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. 😉 Genevieve ================================================= Genevieve E.

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!

Adrian’s “munchability index” (love that term) provides a guide to number of traps, but so does accessibility. How many doors, vents, floor drains, pipe chases, windows, trash bins, etc are in the area you wish to monitor? Think like a pest and place traps where pests are likely to be drawn or to gain access to the area; the more such points, the more traps you’ll want to start with. And, of course, different pests will prefer different points of access, so consider all possibilities. --Dan Dan Wixted Pesticide Management Education Program (PMEP) Cornell University Ph (607) 255-7525 525 Tower Road FAX (607) 255-3075 CALS Surge Facility psep.cce.cornell.edu<https://urldefense.proofpoint.com/v2/url?u=http-3A__psep.cce.cornell.edu_&d=DwMFaQ&c=WO-RGvefibhHBZq3fL85hQ&r=EYdhJ0HrhAMcA2aVQ-I4N7lml00zxsXPbHYeP7843No&m=47rRqN4dGhVawHCJdBW0_2iBMTjcR-LCkKdusQ-2cag&s=sl4OflQhgHr37uer_wBU60xFtyZmqTyz-L3BG_1Y8Zg&e=> Ithaca, NY 14853 dj...@cornell.edu<mailto:dj...@cornell.edu> From: 'Lindsey Gibson' via MuseumPests <pestlist@googlegroups.com<mailto:pestlist@googlegroups.com>> Sent: Tuesday, July 21, 2020 9:06 AM To: pestlist@googlegroups.com<mailto:pestlist@googlegroups.com> Subject: [PestList] Advice on blunder traps/m2 Good afternoon, I am currently reviewing IPM procedures in my organisation and hoping for a bit of advice on placement of blunder traps. At present the number of traps in each of our archive strongrooms is not consistent. This is in part due to accessibility of each space. I would like to increase/reduce trap numbers (and regularity of trap placement where possible to have a more accurate comparison of pest numbers in the different spaces. I have not been able to find any guidance on an optimal number of traps/m2. Can anyone direct me to guidance on this/advise me?
