Hi Fran, I know, that the fungus called Beauveria bassiana was tested successfully in the past against fruit flies, weevils other stored product insects. Further the patented formular Aprehend should have admission against Bed Bugs (Cimex lectularius) in 49 US-states and Puerto Rico and 2019/2020 in California and Canada. For Europe we have no admission against Bed Bugs yet. But I would not use this product in collection storage rooms, if you know about the source of Bat bugs in the roof. Collect one of this bugs and let him determine from a insect specialist or pest control expert. Maybe it is Cimex pipistrelli known by bats. See more https://en.wikipedia.org/wiki/Cimex Sealing gaps to the roof, look at the sources (Bats are actually in the roof??) and monitoring with blunder traps should solve this non-museum-pests-problem.

I received an email seeking advice on a product used to kill bed bugs – Aprehend<https://www.aprehend.com/treatment/>, a “natural biopesticide composed of Beauveria bassiana fungal spores” Here’s what the person described: Bed bugs have been found in traps in the collections storage room (it’s a standard office-size space with a locking door). A plan has been approved to use a product called Aprehend in the collections room. The manager says it gets applied via a pump spray bottle, and they would spot apply along the floor and baseboards. The door to the collections room would need to be left open to ventilate the room after application. I have recommended that they only leave the door open while staff are in the building, but that the room gets closed again at night. I’m wondering if a) are there any milder pesticides that could be applied first (albeit, time is of the essence with bed bugs), and b) if the Aprehend is used, will it be detrimental to the collection in any way? There are rarely people in the collections room (no curatorial staff at the park), so it’s curious how the bugs got in there in the first place. The park has bats in the roof, and is wondering if they could be the vectors of the pests. Does anyone have any experience using this product, or any thoughts on whether it would be detrimental, if applied in the way that is described? Thank you!
