Hi Todd, There is paper from the Stockholm IPM 2019 conference proceedings I contributed to where we tested Long Lasting Insecticidal Netting (LLIN) which contains alphcypermethrin and is typically used for mosquito control. It contains results from extensive materials testing, entomological lab, and practical field application. We saw promising results against clothes moths and dermestids. Happy to share more info if you or anyone else is interested.

Permethrin also used for head louse control. Here's some information about the mattress liners. ActiveGuard Mattress Liners are treated with Permethrin and will continue to kill bed bugs and dust mites for two years. ActiveGuard Mattress Liners are the only mattress liners that actively kills bed bugs within 72 hours. These liners not only kill the current bug infestations but will protect against new infestations. ActiveGuard Mattress Liners have been implemented in major hotel chains internationally and nationally. ActiveGuard Liners were initially developed as a tool against dust mites that produce asthma-associated allergens by a team of medical entomologists in London. These durable mattress liners were developed as a natural extension of the globally accepted use of malaria nets. Permethrin-impregnated bed nets have been used for decades to provide mosquito protection because of the repellent nature of permethrin against mosquitoes. EPA issued a new label for ActiveGuard Liners in 2012, removing use restrictions; it is available for people of all ages, even small children. Louis N. Sorkin, B.C.E.

I’m not finding any information about it on the Bayer US website. I’ll see what I can dig up for you. As Riza mentioned, there are permethrin products designed to be applied to clothing, camping gear, and the like for protection against ticks. (You can’t do this with most permethrin products...just the ones whose labels say you can.) However, those are different products than Perigen, so the precautions and “length of service” may be different.

Apparently "Perigen" is a pesticide connected to the Bayer company, and "permethrin" is the active ingredient. I had never heard about Perigen until today, and I am wondering if anyone on the list is familiar with it. I am interested to hear anything you might have to say, but I am curious about a few things in particular. 1) Are carpets/rugs treated with this material safe? -It looks like there are a lot of warnings about storage/application of the actual pesticide. I'm more looking to confirm the basic safety understanding on whether it's toxic/non-toxic to visit/live in a house with textiles treated with this material. General questions a museum should be aware of like: "If people touch the rug, do they need to wash hands before eating", or, "this material has been found to off-gas toxic fumes for decades- it should definitely be removed if you find anything treated with it". 2) How long does the pesticide stay "active/present" in the rug/carpet after treatment? These rugs are about 30 years old. 3) The wool carpets/rugs in the house seem to be pest free after 30 years. One could make the argument Perigen seems to be working. I'm surprised I haven't heard much about it in IPM forums. I understand why museums wouldn't treat collection objects with it, but I'm more curious about institutions using it to treat pest issues in "non-art spaces" (carpet in offices, general storage spaces, office furniture?, etc). My guess is it's not widely used for a reason- does it have some major downsides? Maybe it is widely used and I have just been out of the loop until now- you learn something every day.
