There’s a product that used to be called EcoRaider (I think it’s called EcoVenger now) that worked for me. It’s pet safe, kills eggs, and has residual effects for two weeks. I applied it EVERYWHERE, then applied it again two weeks later as recommended. I sprayed a bedbug and it seized up instantly and died.

I can’t recommend it enough, I was freaking the F out when the infestation started. Check it out online, it has awards from Entomology societies.
