A little off topic but kind of concerning. About 10 years ago when we moved to this house, I researched permethrin because it was recommended as a good way to protect against mosquitoes but not as scary as DEET. The safety sheets I read said that permethrin was carcinogenic when inhaled. The research strongly recommended avoiding spraying permethrin and if that’s necessary, spray it outdoors while wearing a respirator. This was to be limited too because permethrin is very toxic to honey bees. Since permethrin can’t be absorbed through the skin, it’s not carcinogenic when work on clothes. For that reason, I have been a big fan of Insect Shield bandanas and clothes. They arrive pretreated.
But this thread started me researching again. The safety sheets I now see have been updated. The only serious warning about toxicity is in regards to bees and marine life. In fact, it appears now permethrin is being used as a wide-spread pesticide for crops. But the safety articles no longer warn against inhaling airborne permethrin.
I find that concerning and worth consideration. Ymmv
