DDT still works, especially limited localized application instead of the widespread agricultural saturation like was done in the 1950s. I have a recipe but lack the procedural expertise to process it and unfortunately my chemist colleagues (I'm a math professor) have so far refused to assist. I would absolutely use it around my vacation cottage to keep the grandkids comfortable. Having a small supply would also be comforting to my wife who expends considerable effort to avoid bedbugs when we travel.

Bear in mind in this case the bed nets the mosquitoes are avoiding were treated with DDT.

Without looking it up I'd be willing to bet it was DEET and not DDT. Or maybe permethrin or some other pyrethroid.

you are damn right. mosquito tends to avoid pyrethroid treated surfaces including bed nets due to excito-repellent mechanism. though DDT still works as confirmed in one of my bioassay at a town Nassarawa near kainji dam in nigeria where i recorded high mortality using DDT WHO biassay kit, the health risks is what toned down the use and also high resistance acquired during post world war II.

When I was an early elementary age bicycle rider we used to ride thru the DDT fog from mosquito control trucks in the neighborhood. 50+ years later still here. A few bednets won't hurt anyone.
