It looks like it could be a Casemaking Cloths moth.  Similar to a Webbing
Cloths moth, but slightly darker wings with spots.  I would try putting a
pheromone lure (specific to Casemaking moths) in the area and see what it
shows after a few weeks.

Test tape for adhesion to desired plastic bags or sheetings beforehand on a 
practice/Faux object throughout the whole process if materials(tape or bags)or 
cold treatment is new to you. Some tapes appear to stick well and can fail 
during the freeze/rest cycle. JTV

Hi Todd

Regarding the thickness of the plastic wrap/bags, thicker garbage bags/sheet 
plastic is used mainly as it is stronger when handling and there is less 
moisture transmission through the film than with thinner films. As a rough guide
- disposable shopping bags/bin liners are about 1ml (you should double bag if 
using this type)
- ziplock-style sandwich bags are about 2ml (and some have a moisture barrier 
layer)
- 'tough' garbage/garden refuse bags may be 4-6ml. Many of these types of bags 
have reinforced layers that adds to their strength.

You're not creating an oxygen barrier so holes and tears aren't such an issue. 
If you find scrapes or tears just repair them with tape.

One more thing. When you're freezing a lot of items you may find water 
building-up under and between bags of frozen items. You can reduce this by 
using fans to keep air moving over the objects post freezing.

 Best wishes
Alex

Hello Everyone,

Good thread- very informative.

Since the topic of freezing is going on here, I was wondering if I could pick 
your brains on a few things.  Hopefully this doesn't take us to far off topic.

1)  Does anyone here have strong opinions about the mil of plastic used in 
freezing treatments?  Is there a good "go to mil" that you like for freezing 
bags?  Is the only downside to a thinner mil its greater likelihood of tearing, 
or does it have a less desirable affect in other aspects of freezing too?

2)  How big of a problem is it, when loading a freezer, if a small scuff is 
made in the plastic?  If there is any hole/scuff in the plastic membrane (even 
a small fraction of an inch) does that compromise the object inside?  If the 
scuff is made only on the outer bag, and it is "double bagged", does that outer 
bag need to be taken off and "re-bagged"?

If anyone has opinions on these issues I would appreciate your feedback.

Thanks!

   If you can make a small breech in the wrap without risking the pieces you 
could get the desiccant
