[PestList] RE: ungluing insects

[Dee Stubbs-Lee]

On a similar note, we once successfully extracted a live baby mouse that had 
gotten stuck to one of my sticky blunder insect traps by gently cleaning him up 
with baby oil on swabs. The little guy (whom we named Mr. Bojangles) survived 
the ordeal and was taken home and kept as a pet by one of my big hearted 
coworkers for a week or so until he regained his stamina and could be released 
outdoors.

Hello,

I'm quite new to this group and am following the insect identifications with 
great interest!

My question for you is the following: what means do you use to loosen insects 
trapped in sticky sheets so that they can be properly examined under the 
microscope? During our experiments with solvents and sticker remover, all kinds 
of things kept sticking to the insects, making them difficult to study.
If possible, please provide suggestions of products that we can get in Belgium.

thank you very much!

With kind regards,
Riet

RE: [PestList] catch and release traps

[Dee Stubbs-Lee]

Hi Alex,

I appreciate where you are coming from, however there is a big difference 
between sticky blunder traps (targeting insects) and glue boards (targeting 
rodents). I agree that the larger rodent-type glue boards are inhumane and I do 
not use them precisely for that reason. The small sticky blunder traps, 
however, are the best tool I have for insect monitoring, which is critical for 
preventive conservation of collections. While I have occasionally (rarely) 
found a small baby mouse stuck to the blunder traps, they are generally not 
strong enough to hold rodents. When needed, I use snap traps for rodents, which 
generally kill efficiently with hopefully minimal fear and suffering for the 
animal. Ironically, as Gretchen pointed out, live traps are probably the least 
humane of all because if not found immediately the rodent can meet an 
unpleasant death from starvation / dehydration before being detected. Careful 
attention to housekeeping and exclusion from our buildings is the best defense 
against having to kill creatures unnecessarily in the name of our work. None of 
us enjoys killing any creature, but sometimes it is simply unavoidable.

Thank you all for your thoughtful response.

We do have a very robust IPM program in place. We have low pest activity and 
the space is well monitored, cleaned and maintained. We have not moved away 
from traditional traps and we still adhere to the highest standards in 
collections care.

That being said this question has been raised time and again by many visitors 
and other staff members that find it uncomfortable that we still use sticky 
traps. Although I do my best to explain this is industry standard there has 
been a call for us to look into it, so here I am. Whilst I appreciate that 
ethical traps may not be possible at the moment, I think it is always worth 
asking the question to the community to make sure there isn't something new we 
could be trying. I am always looking to improve our service to make it as up to 
date and robust as possible. Our collections are of course our priority.

Thank you again for all of your input and thoughts on this.

Kind regards,

Alex

THIS IS AN EXTERNAL EMAIL



I also completely agree with Fran and Joel’s response was excellent.



As conservators and collections care staff, we are responsible for maintaining 
collections to the best of our ability. In relationship to this list serve and 
to the question under discussion, it is our responsibility to protect those 
collections from pests – insect, rodent etc.  If we can do it in a humane 
manner so much the better. At this time, the most effective way to monitor for 
insects is with sticky (glue) traps or light traps (depending on the insect).



The most humane manner to monitor for mice is a snap trap. Catch and release 
rodent traps are available but extremely staff intensive.  If the mouse is not 
released in short order it will die of dehydration (within less than a day).  I 
once saw a female mouse who had given birth in a catch and release trap – 
with-in 12 hours she and her litter were dead. That is not humane. If you 
release near the building they will probably come back in, or will be killed by 
mice already living in the territory they were released. Poison is horrid for 
the mice (they bleed to death internally) and will die in the walls or under 
cabinets, attracting dermestids.



By using accepted standards of IPM – Understanding what is in your building or 
collection through monitoring, blocking holes into the building, good 
housekeeping, managing environment, etc. we can reduce infestations.  This is 
labor intensive, but is much safer for the collection and for staff and public 
than any other method.

Good luck

[PestList] RE: silverfish damage

[Dee Stubbs-Lee]

It’s consistent with the sort of damage I’ve seen with silverfish as well. 
Conventional wisdom says silverfish are associated with high RH, which is 
generally true, but I’ve also often collected live ones in surprisingly dry 
ambient conditions. One tip to keep in mind if you are using sticky blunder 
traps to monitor for silverfish activity: the silverfish often get stuck to the 
sticky strip on the underside of the trap (the one that holds the trap to the 
floor) as well as or even instead of the sticky pad inside the trap, so be sure 
to check the underside.

Good luck!

This does look like silverfish damage. The hole is consistent with damage I 
have seen and it looks like there is grazing as well. Do as Volker suggests, 
and look for thin spots or trails.  This indicates grazing.

What are your environmental conditions?  Silver fish much prefer warmish, humid 
areas.  Do you have a water source (sink, drain?) in the area.

To determine if it is active or not, and to properly identify the culprit, you 
should monitor. Place blunder traps (sticky traps) in the area around where you 
suspect activity, and under sinks, around the edge of the room.  If you are not 
catching any insects then it is probably inactive.  Good idea to continue 
monitoring though.

Good luck

dear mike,

I think, it’s hard to tell – if a damage is recent or historic.
you could ask a paper-conservator.

if the paper is pretty dusty and the feeding sites aren’t – than they might be 
recent…

I think the damage  is from a silferfish!

hold the paper in front of a light source and look from the other side,
then you should see the thiner parts in the papersurface…

Hi Dee
It's a bit tricky with the photo quality, but at least some of the specimens 
appear to have the attenuated wings that are typical of Dorypteryx. If you do 
an image search for that genus, you will be able to see the form of the adult 
(with wings) and the nymphs (without).
If they are Dorypteryx, this is a booklouse/barklouse that is turning up more 
frequently in museums and galleries, but it seems to cause few serious 
problems. As others have said, it would be a sign that humidity levels may be a 
bit high.

RE: [PestList] Need for advice

[Dee Stubbs-Lee]

We have a similar whale jaw bone / former door frame, which has been on 
permanent exhibit in its current installation since the 1990’s. As Rich noted, 
freezing hasn’t been an option  due to the size. We’ve not noticed much pest 
activity around it, however marine mammal bones are notoriously greasy and we 
have observed a steady but very slow flow of molasses-like material from it 
onto the floor around its support mount. The specimen in question has been in 
the museum collection since long before we had a conservation staff, and I do 
not have any information about how it was first processed or prepared upon 
collection by the museum, although we do have a photo of it in-situ in use as a 
door frame.

This sounds as intriguing is it will be challenging. I’ve seen a few such 
displays in which the hollow jaw bone had been inhabited by mice (within a 
museum), and by spiders, paper wasps and mud dauber wasps (outdoors). The bones 
might be endowed with yet other cavity-dwelling beasts. Freezing is not likely 
an option (who has a freezer that size?). If you’re concerned that any beasts 
might be transported indoors, then consider wrapping or tenting the bones, and 
purging the interior with a gas that either has toxicant properties (less 
desirable for many reasons) or one that merely displaces oxygen. Perhaps, you 
might initially assess the bones in a garage setting where any escaping 
villains won’t pose risk to museum accessions.

Good luck!

Dear all,
Our local Botanical Gardens has had a whalebone arch on display in the open 
since the 1800s.  There is very little known about the arch, other than that it 
is the jawbone of a whale, possibly a Fin whale or a Blue whale.  As you can 
imagine, it is in a very weathered state, and it recently collapsed, so we have 
been asked to bring it into the museum to work on it.
Our conservator has never had to work on anything like this, and we are also 
concerned about the potential introduction of ‘unwanted guests’.
Do any of you have any experience with this kind of object, or any advice on 
how we should proceed?
Frankly, at the moment, we are feeling a bit overwhelmed.
Grateful for any advice.
Thank you,

Geraldine

Interesting, thanks Adam. I think I may also have found evidence of this 
species in prior years (typically around late December) though its identity had 
not yet been confirmed. I have not yet seen any such creatures so far this 
year, but will definitely keep an eye out. Can we assume this is an incidental 
visitor from outside and not a major threat to collections?

Subject: [PestList] IPM for huge incoming collection of mounted mammals

The New Brunswick Museum has acquired a very large collection of over 400 
mounted mammals. Some are very large species. About 60% are head and shoulder 
mounts, the other 40% are full body taxidermy mounts. Some have some associated 
diorama materials.

These will be coming to us from an off-site, non-museum out of town location, 
where I am told they are densely stored in about a 1700 square foot space on 
private property. I have not seen this collection in  person, only from photos. 
I am they need to be moved to the museum’s collections storage imminently, 
possibly within a few weeks and with as short as possible a processing 
turnaround time. The space that is being considered for housing them is the 
museum’s current preparation workshop, which is about 1780 square feet. We are 
no longer able to use this room for preparation work (wood working, painting, 
etc.) due to ventilation not meeting current health and safety guidelines. The 
workshop has direct access to a freight elevator and to an exterior single size 
door. It has a concrete floor and is located on the museum’s basement level. 
The adjacent collections storage rooms house our most pest-vulnerable 
collections: textiles and ethnographic collections. This workshop room is 
located directly below the conservation lab and loading bay.

We have a small walk in freezer for IPM that is used by all museum departments, 
but this is not adequate to process this large acquisition, and many of the 
mounts may not physically fit in any case. The curator in charge of the project 
would like to avoid hiring freezer trucks, and prefers fumigation.

These mounts are from within the last 50 years or so, so I am hoping that 
arsenic and related hazards  may be less of an issue than with older mounts, 
although I worry about health and safety aspects of fumigating on site, 
especially as my office is immediately above this space.

In addition to my pest related concerns (mainly protecting our other 
collections), I have been told that some of the mounts have visible mold growth 
as well as a musty odour, so these are challenging on many fronts

I am looking for advice on freezing vs fumigation (onsite or off site) vs 
inspection and HEPA vacuuming only, and for dealing with this on an extremely 
tight time frame and with extremely limited resources. I have never dealt with 
an IPM project of comparable size and scope before, so all advice is 
appreciated!

RE: [External Email] [PestList] RE: Advice on blunder traps/m2

[Dee Stubbs-Lee]

I typically monitor about 50 – 60 blunder traps across 4 collections storage 
buildings once monthly. That’s the best I can do time-wise as the only 
conservator on staff. More traps are theoretically better, but as Genevieve 
said, the traps are only as useful as you have the ability to monitor. I have a 
higher concentration of traps where organic materials are stored, and where I 
have had past problems, and fewer where the collections are less inherently 
attractive to pests. Building features such as exterior walls with windows and 
doors, proximity to areas where food is stored or consumed, plumbing pipes, 
electrical conduit and odd corners that are hard to keep clean, places where 
clutter accumulates, flooring (carpeted areas tend to have higher pest counts, 
raw concrete can be associated with dampness), and ventilation will all affect 
what you’ll find in your traps. Over time, you’ll get to know your buildings, 
and will be able to pinpoint the areas you’ll most need to pay attention to. I 
generally place my traps against walls, and in close proximity to a describable 
landmark (for example, Room B12, next to shelving unit 95), and I will change 
the locations periodically, depending on what I’m catching.

I agree with Dan (and everyone else).

Rooms don’t need identical trap amounts to show activity. Some of it depends on 
room size and accessibility. Placing traps as Dan suggested will give you a 
good idea of movement and risk. I sometimes put traps by the bottoms of 
herbarium cabinets that are especially high risk or on shelves by slide boxes 
to monitor volume of Psocids.

I know maps are something you definitely don’t want to share online for 
security reasons, but I find putting points on a map really helps me when I 
walk through a space to assess what I need.

Good luck! And I personally find that less traps but that you check 
consistently is better than more traps that you have a hard time getting to and 
are more likely to put off. 

We’ve also found that rooms have higher humidity/temperatures have more pests, 
so maybe bump up the blunder traps in those rooms too.

Thanks Dan. I’ve tried to put traps either side of openings but, definitely 
need to review this and think like a pest!

Adie - yes It’s  just me doing the insect pest traps, but there are rodent 
traps around the building perimeter that are, I presume, monitored by a pest 
control contractor through our estates department. I am the archive conservator 
but also deal with collections care  including IPM.  At present I only have 
traps in strong rooms, plant room, archive staff offices and search room. It’s 
probably a little inconsistent  but we are a local authority archive based 
within the county council headquarters. I’ve tried to monitor in any space 
where archives are used and in adjacent rooms but undoubtedly we will  get 
pests coming In from other areas.

Thanks both!

Hi Dee
Bryobia are visitors, often coming indoors during the summer. They feed on 
plants, so won't eat any exhibits, but they often occur in large numbers and 
accidentally squashing them will leave a red stain, so  they need to be treated 
with care if they do find their way into cases or stores.
There is a fairly good summary about them here -

(the one that holds the blunder trap to the floor). In some cases I have had 
many small silverfish on that underside glue strip and none at all on the main 
glue surface on the upper side. I assume that means they like to stick close to 
the floor surface and sheltered areas, especially when they are young. I am 
going to experiment with this method, though I’ll have to invest a whole 25 
cents per trap rather than 5 cents as Canada has stopped using pennies! ; )

I started this trick many years ago and find it works great.  Silverfish love 
to squeeze themselves into dark cracks and crevices.  The pennies give them a 
perimeter of crevices around the entire glueboard.  It's particularly helpful 
in situations on shelving where starchy items are stored.  It's also great 
around the perimeter of a basement concrete floor where silverfish like to hide 
in the expansion joints.

Subject: [pestlist] Silverfish - Next Steps

Hi All,

I have reason to believe this is a silverfish, and I found it in the archive in 
a corner. The trap is not directly near paper, but there is a lot of 
paper-based historic materials in that room. First, is this a silverfish like a 
think it is? Next, what should I do in terms of notifying my supervisors and 
what are the best practices for next steps? Should a professional pest 
management company come in to inspect the space. I only found one silverfish, 
so does that mean there is an infestation or only a small amount (which is 
still problematic but not as big a cause for alarm).

I look forward to hearing from you all. Thank 

[pestlist] RE: How many monitoring traps?

[Dee Stubbs-Lee]

Hi Elizabeth,

I vary my numbers of traps depending on what is stored in any given room. For 
example, my rooms containing textiles collections have more traps, more closely 
spaced, than do my rooms containing lower-risk items like ceramics. If I have 
something of concern show up one month, I may add a few more traps nearby in 
order to keep closer tabs on the area  for a while. Bear in mind that sticky 
blunder traps are meant for monitoring what’s living in your space, not for 
eradicating any problems, so, ideally, the more traps you have out the more 
accurate your data will be. On the flip side, the more traps you have out, the 
more time it will take to monitor and record your findings. I work for a mid to 
large size museum with collections stored and exhibited in 5 separate 
buildings, but I am a conservation department of one, so I find that monitoring 
about 50 traps in total on a once monthly rotation is about the best I can 
manage and takes me about one full day per month between checking the traps and 
managing my data. You would adjust that to suit your facility, type of 
collections, frequency and type of pest you are finding, and available staff.

Is there a particular ration, per square metres or something that people use

[Consdistlist] effects of roofing tar fumes on collections?

[Dee Stubbs-Lee]

Apologies for c ross posting:

The building housing our museum's Exhibitions Center (we are a tenant within a 
larger commercial complex) has been undergoing major roofing repairs for the 
last several months, and the work is expected to continue over the next year. 
The tar fumes are quite noticeable inside the building at times, and have 
occasionally been unpleasant enough that we have closed to the public. The 
question of what effect the fumes may have on the artifacts (mixed collections) 
has come up. We are trying to assess whether the risks inherent in clearing the 
top floor of all collections and moving them to offsite storage are more or 
less of a danger than leaving the collections exposed to fumes. I have not been 
able to find any hard data to support either argument, but my instincts tell me 
that a major collections move may well be the riskier option, especially since 
our offsite storage options are not climate controlled and have no fire 
sprinklers. Do any of the list members have relevant experience and insight?

Thanks,
Dee

I have seen cigarette beetle larvae eat glued furniture pieces.  They just eat 
the glue, not the wood.

If it's hide glue, that might explain carpet beetles, because I've seen that 
before.

We also just noticed today that the damage you attributed to the powderpost 
beetles seems to correlate with areas where there had been old glue (brittle 
and brownish, so appears to be a hide glue). Perhaps there was a protein 
attraction at play as well as moisture?

Thanks, Tom! It is certainly the worst case of beetle damage I have encountered

had also wondered about possible past storage on a damp surface – anything is 
possible, although there is no obvious musty odour or fungal growth currently. 
I should have mentioned that the legs appear to have had casters or other 
secondary feet at one time, but these are no longer with the piece. There are 
smaller flight holes scattered throughout the whole piece (mostly in drawer

was far more substantial.

Knowing where you are located, the fact some of the wood appears to be 
hardwood, and the large diameter of the exit holes and galleries, I would guess 
it's extremely old deathwatch beetle.  I think the desk probably either sat in 
water or at least a very moist area for an extended period of time before it 
was salvaged and ended up at your place.  Could it have been stored in an old 
barn? or similar situation?  This type of beetle attacks wood damaged by fungal 
invasion.  I've rarely seen it in my 43-year career.

Hi all,

On Friday, one of my colleagues was trying to shift a slant front desk a few 
inches on a carpeted surface. One of the legs caught on the carpeting and 
cracked readily . (We do know that neither carpeting in storage areas or moving 
furniture solo is good practice, but sometimes we don’t live in an ideal

[Consdistlist] should musical instruments be maintained in playable condition?

[Dee Stubbs-Lee]

Dear Distlist,

One of our curators has asked me about the ethics and precedence for deciding 
whether or not a musical instrument in a museum collection should be maintained 
in playable condition. In the past, we have always treated musical instruments 
in our collection as static, non-operating historical objects, however a recent 
acquisition proposal has the curator wondering if we might wish to take a 
different approach with an instrument currently under consideration for 
acquisition. Can you please point me to good, recent discussions of this 
question in the conservation literature and/or policy documents from other 
museums that take this into consideration, in order to help us to make an 
informed decision?

Many thanks,
Dee

[Consdistlist] Vortex fire suppression system

[Dee Stubbs-Lee]

I understand that a "Vortex" fire suppression system has been proposed for some 
areas of a new facility our museum is planning (to house diverse collections of 
humanities, archival and natural sciences material including some particular 
areas of concern for fire suppression such as alcohol preserved collections and 
potentially unstable early plastics). I understand this "Vortex" system uses a 
combination of compressed nitrogen and water mist. I am aware that users of 
"dry pipe" type systems have reported problems with corrosion developing in the 
pipes. I would be interested in hearing from other museums that use this system 
about the pros and cons and whether we should be advocating for or against 
choosing this system.

[Consdistlist] lead time for conservation

[Dee Stubbs-Lee]

At my institution we are currently debating what constitutes a reasonable lead 
time for conservation related work (including condition assessment, treatment 
proposal and agreement, conservation treatment, treatment photography and 
documentation, design and fabrication of any necessary exhibit mounts, and 
packing for travel) for artifacts destined to go out on exhibition or loan. 
While to some extent  this has to be determined on a case by case basis;  for 
broad planning purposes what would constitute a generalized expectation of 
person hours per artifact? If any other mid-size to large museums have policy 
or procedural documents relating to this that they are willing to share, it 
would be very helpful in informing our discussions.

Thank you,
Dee

Tootsie roll slices attached with a hot glue gun. I have incredible success 
with that as a bait. If you use mini t-rex traps the bait will work for years 
as the other mice can't get to it when it snaps shut.

Hi everyone,

I am looking for suggestions for bait for snap trap style mouse traps in our 
collections storage areas. We previously used peanut butter with some success, 
but concerns have been raised about potential staff and visitor allergies due 
to the peanut butter potentially being spread around and urinated out by the 
mice who escape the traps. I read somewhere that gummy bears might work as 
bait, but that was in the context of rat traps and I have not yet tried them 
for mice. (Thankfully, we don't have a rat problem!). Obviously, I would prefer 
a solution that will not add to our insect pest issues. Total exclusion of mice 
is difficult if not impossible as we are in an old building with an infinite 
number of possible entry points.

What you are catching on your glueboards means one thing; they are flying to 
lights affixed to your building at night, dropping down to the perimeter, and 
then walking into your building.  It's time to tighten up your building's 
exterior envelope.  Change your mercury vapor lights to sodium vapor ones.

Hi everyone,

I have recently had a few unwanted visitors in our basement level storage 
(primarily textiles and ethnographic materials). I have attached a couple of 
blunder trap images with a tape measure in centimeters for scale.

I believe the first image shows a hide beetle, partially chewed by the adjacent 
smaller beetle (black carpet beetle?). Can anyone confirm? I have very 
occasionally had these before.

On the second trap, the black one at the top I have also seen before and have 
been previously told it was a mealworm beetle. The two lower ones are new to me 
and appear to be the same species as each other. The photo doesn’t show it 
well, but they are an iridescent copper colour. These were on a common blunder 
trap that was near a pheromone trap for beetles (I’m experimenting) that has 
attracted larder beetles – may be a clue?

Any thoughts?

Thanks,
Dee

​Megan is correct - the first trap is one of the Rove beetle species 
(Coleoptera: Staphylinidae)

all beetles on the second trap are all Ground beetles (Coleoptera: Carabidae), 
the two 'bronzey' examples (bottom left and middle) are Carabus sp. and the one 
top right another carabid species. All are incidentals and of no pest status, 
but if these large beetles can get in then so can other potentially pest 
species so screening on ground floor windows and bristle strips on bottoms of 
doors would be worth considering.

All the best,

Stuart

I can vouch for this – many of my museum’s collections storage areas are 
carpeted (a situation I inherited rather than chose). Despite having 
desperately low RH in the building most of the winter, we still often see 
silverfish in the carpeted rooms – a moldy microclimate under the carpets, I’m 
guessing.

Good evening, PestList’lers – I also point out that a large expanse of any 
floor covering made from a natural fibre, whether sisal or wool, cotton, jute, 
etc., will also absorb and hold a lot more moisture out of the environment 
where it is installed than a floor covering made from one of the synthetic 
fibres (i.e. acrylic, nylon, etc.). So if your floors do not have a vapor 
barrier properly installed, the floor covering will act like a giant sponge, 
sucking up moisture from the floor/ground. If your building does not have the 
relative humidity controlled, the natural fibre floor covering will make it 
even more complicated to control. Mould/mildew spores will love it and flourish 
with abandon….ugh…especially on the side in direct contact with the floor and 
away from the light (mould/mildew is considered a ‘pest’, right?).

Any finish applied to a floor covering, whether fire retardant or stain 
repellency, will be rubbed off as the floor covering is walked on/have stuff 
dragged across it. Meaning it would have to be reapplied periodically. So the 
carrier fluid would be contaminating the space again, whether water (raising 
the RH in the environment) or some other fluid which would off-gas in to the 
space as it dries.

Feel free to contact me off-list if you need further clarification.
Regards,
Meg

I am writing about the choice of floor covering requested by the Director's 
Office at our art museum.  They are interested in installing either Sisal or 
Wool sisal in the Directors office.  There will also be two or three 
accessioned paintings exhibited in this space as well.  I am concerned about 
the tastiness of both of these choices (sisal and wool sisal) to potential 
critters.  The Director's office is in a different corridor than the art 
collections however I am concerned about creating a potentially amiable 
environment for pests in general within the museum.  What do people think?  
Should I continue to advocate for synthetic flooring options which have 
heretofore not been of interest unfortunately?  I do not believe that they will 
be using a foam pad under the rug which is a good thing to avoid any potential 
off-gassing of the foam.  I am also concerned that a fire retardant applied to 
the sisal may be necessary from a safety point of view.  I will off course 
follow-up with an exam of the MSDS sheet of the fire retardant.  But basically 
my question has to do with whether or not a large expanse of sisal is of 
concern to nearby collections on display.  I don't want to be a PEST!

I guess the big question is what is the proximity of the director’s office to 
the collections on exhibit or in storage, especially the more vulnerable 
materials? The shorter the distance, the more urgent the problem. That should

I REALLY appreciate everyone weighing in on this issue!!  Your opinions are 
very interesting to me and those involved in the ordering of the Director's 
rug.  This is as good example as any of the many tangential issues that as 
conservators we are involved with in any museum.



Gratefully,



Ingrid Neuman

I’m not a conservator or an entomologist, but the largest infestation of 
silverfish I ever saw was beneath a 9’ round sisal rug on a travertine tile 
floor.  Ugghhh!

Thanks Leon,

Good suggestions. In my experience, I have quite often found frass piles on my 
sticky traps without the associated pest being trapped. Not sure how they get 
away, but they manage...

Hello Dee- 

I would create a new pest called mouse droppings, the risk would be
Indicator. If you don't have mouse traps set it could easily happen that
you have mice without actually seeing one. I would also track mouse damage
although there's bound to be droppings around any damage.

There is a Notes field with each observation so in the case of damage there
would be some merit to tracking it and describing it in the notes field.
Then you've got a tracking of the damage history.

We do have a search in the works that will let you pull all records that
have a particular word or phrase in the notes field. We are expanding the
export that is currently by start and end date to include filtering by other
fields.

As far as the tracking a reduction to frass of a pest I'll leave that to
those more knowledgeable. I would think that anything feeding off of a
trapped pest would itself be caught.

Thanks, Zak. These all sound like great improvements! I tried Zak's a few
years ago but didn't stick with it. I'm looking  forward to trying it again
soon. One dilemma I've not found a great solution to in any tracking method
(and I'm hoping someone may have a suggestion) is how to track things of
note when there is no actual body count available on the sticky traps --
perhaps mouse droppings, or a previously trapped insect subsequently being
reduced to a frass pile by some other insect the next month. Any thoughts?

Hello - 

One of the advantages of this type of list and having the person that
designs and writes the software is a part of the list and it provides a
direct line of communication not normally available with software products.
I appreciate the comments about my products and do pay attention to them.

The current suggestions we've been working on were the ability to do a
backup of your data to your location and the need to get an Excel accessible
export. We now have answers for both. Under the utilities section there is
now a one click, all inclusive backup. This is a backup that we can restore
your site from. It is not readily human readable, it is made for our restore
system to read. This is meant for catastrophic situations - someone
mistakenly goes through and deletes a large amount of data for example. We
still backup the whole site each night for our purposes.

For the Excel export we've added a link on the Reports page to an Export
page. There are two options on this page. The first will let you define a
start and end observation date (defaulting to your first and last
observations entered) and then you can download the information in a CSV
file format that can easily be imported into Excel. Once in Excel it can be
sorted, graphed, printed and more.

The second option is a complete download of all of your images

Hello all -

I'm am setting up digest capabilities for this list. Digest mode (and it is 
optional by user) will save the emails that have come in over a certain period 
and then mail them to you all at once. If the period is set to one day, all 
emails coming in that day would be sent to you at one time at the end of the 
day.

I can set the digest period and the send time. Digest period options are: 
daily, weekly, bi-weekly or monthly.

If you think you'd like to use the digest mode, please let me know which period 
you would prefer - I can only set it to one.

RE: [pestlist] Wrapping infested objects for freezing

[Dee Stubbs-Lee]

At our museum, the practice is to routinely wrap and freeze most material 
coming in from outside the building (there is quite a lot of it as our 
exhibitions and collections storage are in separate buildings) in a walk in 
freezer unless the items are felt to be at high risk of damage from freezing. 
Our collections storage facility, like many, is overcrowded and infestations 
could potentially spread quickly -- we feel the risk of infestation outweighs 
the risk of damage of freezing most collections objects.
 
I share Alyssa's concern about the wastefulness of using plastic only once (we 
use polyethylene sheeting, sealed with packaging tape), and we do sometimes 
reuse larger pieces of plastic for that reason. The idea of using a reusable 
freezing container sounds appealing on many levels, however, I have always been 
under the impression that it is important to:
 
a) eliminate any extra air in the bag, and
b) seal the bag so that it is airtight
 
Both of those would be difficult in the case of any reusable see-through 
container or bag that I can imagine.
 
Any thoughts?

Alyssa -

You pose a lot of good questions about wrapping before freezing.

I think the foremost reason from wrapping is to prevent ice crystal formation 
on the surface of the object being frozen.  Using any kind of wrap, such as 
muslin, kraft paper, cotton cloth, etc. will prevent this from happening.  Most 
use zip-lock type bags, which can be re-used.  If something has been properly 
frozen, the wrapping will not be contaminated and can be re-used.

For larger mounts, you may want to consider constructing a framework box with 
polyethylene stapled to the 5 sides, and a Velcro fastening system for the 
final side for putting the mount inside and then sealing it with the Velcro 
attached to the perimeter of the polyethylene.  This framework can therefore be 
used again and again.

I can't imagine the object being reinfested after being properly frozen as it 
sits on a countertop acclimatizing; no institution has that rampant an 
infestation which would cause almost immediate reinfestation.

Subject: [pestlist] Wrapping infested objects for freezing



Hello, 
Here at the Royal Saskatchewan Museum I wrap anything to be treated for insect 
pest infestation in polyethylene plastic prior to freezing. These objects are 
most often natural history specimens (mounts) and textiles or 
leather/hide/feathered objects from our Aboriginal History collection.
Lately this practise has come into question - is it not a waste of time and 
resources to do this, especially since much of the plastic must be thrown away 
to prevent possible cross-contamination? Could the wrapping stage be eliminated 
for adsorbent objects in good condition?
My reasons to continue wrapping are listed below. However, I wanted to pose 
these questions to the list for thoughts, from a practical point of view, as to 
whether wrapping is important, and if so, how and when. Has anyone has come up 
with a more environmental alternative? For example, has anyone found a line of 
vapour -proof, washable tubs that would do the same job for a variety of sizes 
of mounts?
Reasons for wrapping: 
1. To contain infestation while transporting specimen to the freezer 
2. To prevent moisture content changes in the object during freezing, which 
could result in dimensional changes and physical damage
3. To prevent damage from possible freezer failure (water drips/ floods, debris 
from ceiling) 
4. To prevent condensation from forming during its acclimatization before the 
bag is opened 
5. To prevent (or slow) re-infestation during acclimatization 
Your thoughts and ideas on the subject would be most appreciated! 
Sincerely,
