Frontline is fine, we've been using it on our numerous dogs and cats for as long as I've had snakes. It's the cheaper brands that you have to look out for, and like the previous reply said, the stuff you put in the carpet or spray.
Just use common sense (don't touch it for 24-48 hrs, etc) and you should be just fine!

318 pairs of ribs.
In stating this I place reliance
On a seance with one who died for science
This figure is sworn to and attested,
He counted them while being digested."

Pakistan is looking shifty,
North Korea is too risky,
Bomb Iraq!
