Which would you rather have in your home; bugs, or spray strong enough to kill them?

Watching TV that question popped into my mind as they ran an Ortho™ commercial. As I was watching the actors in the commercial spray deadly poison around their baseboards, sills, cabinets, entry ways for piping and any other place creep-crawly critters might squeeze in, I wondered if the cure might be a lot worse than the disease. What do you think? Live with the occasional spider, or spray every way that they can get in, and hope the poison doesn’t affect humans.
