if you spray your house, leave it for an hour or two, return then air it out. do not breathe it in as its a toxin for small creatures
I would call an exterminator, and go stay at a hotel for a week after they come. We had baaad fleas in the house we were going to move into when I was 8 months pregnant, so we sprayed the floors down with bug spray before putting the carpets in (so the carpets wouldn't have spray on them...we also have a toddler), and I stayed away for a full week before we started moving things in.
it's VERY VERY bad to breathe bug spray while pregnant. avoid it however you can.
Very bad!!!!! And unless you are drowning them right on their skin it will not get rid of them! I would get some sage esential oil or pepermint and put a few drops on cotton balls and put around rooms to keep them out.
But spiders are good bugs! They keep bad bugs away! I have some around my house and as long as they are not biters I leave them alone
