It is hard to get DDT out of the food chain because it is an oily substance that doesn’t break down or mix with water. So it’s probably not a great idea to spray it all over the place. But I can’t imagine that controlled application inside a residence would be much of a threat to anything or anyone.
The problem with the libs is that they get their kicks from controlling our lives and banning creature comforts, yet they always seem to be able to obtain anything they want. Kind of like how the gun grabber politicians all surround themselves with armed security guards.
A lot of hotels near the border have their employees bring back DDT laced pesticides to use on bed bugs when they come back from visiting family in Mexico. So as long as that continues it will be hard to get rid of it entirely.
