Also if you have a bug problem that needs dealing with, and don’t live with pets, toddlers or now apparently anti-vaxxers. 1 part Diatomaceous Earth, 1 part Borax, spread in a thin covering around the affected areas.
When I was a kid my dad would make ant baits out of boric acid and honey, keeping them out of reach of the dog and being very clear with my brother and I that this was poison. I did the same in an apartment a few years ago to take care of an ant problem, and it worked great. About 2 parts honey to 1 part boric acid powder, I think?
