I have a cat and ive never had to bomb the house.

I use Frontline on the cat to keep fleas off the cat and i use Flea/tick spray on the carpet all around the house to kill them that way.

Doing this monthly when i apply the Frontline has kept fleas out of the house for years.

PAM will kill them faster than any bombing as Ive used a can testing it out on certain bugs found around the house, and all subsided within 10-20secs.
