I work in the Pentagon, and the building guys strongly advocate steam cleaning as the best way without tossing around alot of toxic fumes (which everyone hates). My guess...without DDT around...every single house in America will have a steam cleaner within five years.
You’d think the Pentagon would have phasers or something from the black project to deal with them. :)
They used the planet killing carbon dioxide to freeze kill the bugs but you could hear the Ozone screams form northern Colorado. /s
I hope we regain sanity and bring back DDT.
