My go to pest killer is "Tempo SC Ultra" good residual, pet safe AFTER it dries, listed safe for food facilities, kills A LOT of different pests (not an instant knock down, so don't think it will kill stinging pests on contact, ask me how I know!). I spray the exterior of my buildings in the fall when those damn bean beetles (orange lady bugs) and boxeleder bugs start to look for winter shelter. End up with piles of the damn things at and around the foundation. Not sure what is in it, but spraying the perimeter of buildings, and entry points like the sill, windows, and doors, has proven quite effective. Heed the warnings though, it kills aquatic life as well if allowed to contact those areas. Kinda expensive, but a little goes a long way.
