I don’t know how lasting a bug bomb will be for protection. You might have to do it a few times per year. I think bug bombs are instant death not preventative?
I didn't even think about bugs and in California we have termites, flyers and subterranean types. I am scheduled to have my house tented (every ten years or so I do it) so I guess that should take care of it for a while. It's unbelievable how much damage termites can do in a short time!!
