Thank you for your thoughts Richard! This is exactly what I was wondering. I think we need to do an intensive review of the cracks and leakages into buildings (we have several buildings built between 1948 and 2012 with a lot of leakages), see what we can’t seal up, and consider spraying there if we have evidence that those leakages are contributing to our pest problems.
Best, Jodi From: pestlist@googlegroups.com <pestlist@googlegroups.com> On Behalf Of Pollack, Richard J Sent: Monday, December 5, 2022 3:30 PM To: pestlist@googlegroups.com Subject: [PestList] Re: pest management professionals Jodi, It is my professional opinion that preventative pesticide applications deserve more scrutiny and justification than is the norm. Too many properties are treated ‘just in case’. I’d ask what specific pests are the cause of worry, what are the action thresholds for damage and for pursuing treatment, and what other strategies might be pursued to minimize the likelihood of pest invasion and resulting damage. Spraying the building exterior may not be the best choice to reduce intrusion of pests. Instead, consider modifying the exterior so it is less attractive or conducive for pests. Tighten up entry points to exclude those pests. Protect items of value inside from pests. Monitor for pests, and use the data to inform decisions on how (and when and where) to prevent or mitigate specific pests. In some cases, a carefully crafted preventative barrier application of a residual pesticide in or around certain rooms, corridors, and cabinets may actually offer more benefit than risks within a museum. A standard ‘spray and pray’ strategy so often demanded by homeowners and embraced by some PMPs seems fully inconsistent with modern IPM. I look forward to other replies and perspectives. -Rich Richard J.

I’m wondering if someone can point me in a specific direction to more deeply understand the do’s and don’ts of working with PMPs on preventive spraying. What is spraying good for? When and where should it be done or not done? The last two museums I was at in South Dakota had preventive spraying going on to some degree—not in collections spaces obviously but other areas of the building. Here we have a PMP spray at our associated university buildings but not at the buildings where collections are exhibited and stored. I’m wondering if we should be doing something more in terms of treatments around the exterior of the building to stop pests from getting in. Resources and advice on preventive treatments with PMPs greatly appreciated!
