I wore a gas mask. We got them before we did the bug bombs. You're probably right about the vacuum though.
Funny side story, we had friends with keys to the house coming and going every day, so when we bug bombed, we put signs on the doors that said "DO NOT ENTER UNLESS YOU WANT TO DIE!"
The next day, while we were all working, the police raided the house (I had a minor warrant, long story). They called in a SWAT team because they thought the house might be booby trapped.
