Are flea bombs safe ?

I have a flea infestation and been having to vacuum like 5 times a day and give our animals baths constantly and wash everything every other day. People are suggesting using a flea bomb but others are saying it is not safe and that it is bad for your home and air. Doesn’t it get all over everything ? We have a 1 year old and I’m also pregnant so this concerns me. But we’re at the point where me and my poor sweet baby have bites all over us. I feel like a bad mom right now.
