Treating your house and yard are just about the only way to totally eradicate the ticks. And doing that, depending on how you choose to do it, could be risky to the health of your pets. I have resorted to chemical treatments of my yard in the past, but only when I knew that I could keep my cats and dogs out of there for at least 24 hours while the treatment worked and the grass and beds dried.

Frontline Plus is a great product, but like you said, it works when the ticks bite, which is a good thing, but if your animals are bringing in ticks, further action in treating your yard and home are probably necessary.

Good luck!
