Josie, I would generally discourage efforts to spray the outside of the building, as I think it would neither be particularly effective nor sustainable. One could also argue that it wouldn’t be environmentally responsible.
What kind(s) of flies are entering in abundance, and during what seasons? Are you burdened with them now? If so, these likely are cluster flies that have been overwintering within the attic or wall voids, but then cause havoc within the human-occupied spaces. There are options to better manage these flies that don’t depend upon frequent and widespread pesticide applications. I anticipate that dermestids, booklice, and silverfish are already in residence within the museum. Accordingly, I’d encourage mitigation and prevention efforts inside to protect your accessions while continuing to exclude entry of new ones from outside. Richard J.

Some of our biggest threats are dermestids, booklice, and silverfish. We also play host to many flies, which not only poop on our collections, but provide a meal for and attract more dermestids. Attempts at sealing our buildings have been made but we still struggle. Our problems are so extreme that we're considering spraying the OUTSIDE of our buildings to help mitigate these risks. The pest company has recommended the following products: demand, Temprid, and Delta guard granulars. I've spoken to the pest company about wanting to keep the pesticides outside because we're a museum, and they understood. I was hoping to receive some opinions about the safety and efficacy of the use of these chemicals and others at your institutions for pest management. Please feel free to share any experiences you find relevant to this topic, positive or negative! Thanks.
