Would bombing work?

Okay well we live in fl so of course in the summer time there is tons of bugs, but we keep getting brown lacrosse[spelling] spiders in our house, gross and scary right? Well if we were to bomb our house would that get rid of them?! We have no clue were...

there comming from. When we first moved in there was a big one on my bathroom door. We thought it was becuase it got between the new carpets when they brought it in and blah blah blah
But my mom has no money. So we have no clue how much it would be.
And there have been plenty of other bugs.
So would boming work?! And how much would it cost?
Please and thank you :d

Well first off those spiders are posianes so they can hurt you bad... I live in florida so I get roaches bad but you can go to wal mart and get raid bombs there only like 5 -10 dollars not that much and that should work... let me know what happens but be carefull
