Hi Jodi, There are a number of reasons to resort to “spraying”, primarily it is a form of blocking. As you noted, you do not want to do anything like this in direct contact with collections, nor any general spraying or fogging with pesticides. Most often, a barrier of residual contact pesticide (dust, film, paste, spray) can be laid or sprayed into cracks and crevices. This must be done carefully and should be done by a PMP. This is particularly helpful in controlling pests (silverfish, cockroaches, ants, etc.) in old buildings where there is no other way to eliminate all of the cavities. Our PMP uses a residual pesticide around the gaps where plumbing comes through the walls, areas that the plumbers do not want to close up because they need to access. This kind of treatment is also helpful if you serve food in the building.
One very important procedure is to make sure you have the SDS of any pesticide that is being used. The need for this should be written into the contract. One of the things we did when hiring our PMP was interview them to determine if they understood what IPM was and were willing to work with us. I have talked to the PMP technicians at length about what we expect (also should be written into the contract) and have toured the facility with them. We meet on a regular basis, so that I know what pest issue are going on and what recommendations they are making to facilities. We work together on the solutions, as needed. See the section on Solutions in MuseumPest net. – there is a page on crack and crevice treatment. I hope this helps.

Do not click links or open attachments unless you recognize the sender and know the content is safe. Hey all, I’ve found the guidance for working with pest management professionals on the museum pests site. 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!
