Hm yeah, that’s fair. I wonder if limiting it to indoors pests, specifically the big two invasive species, would have prevented that. To my (very limited) knowledge, bed bugs aren’t eaten by many things. Bats? German roaches eat them but we don’t want them either.

I’m not overly attached to DDT though, a public health program of Alpine spraying indoors would probably do the trick. I doubt anyone has the political capital to get it done, but the return of bed bugs will be disastrous
