I live in ft. worth tx. I have a acre, and my poor dogs get fleas and ticks so bad in the summer. Frontline dosnt work at all. Plus I dont want to use chemicals on my dog or yard. What can I use to treat my yard without chemicails and my dogs.I spent 40 bucks on the cedarcide spray, only works to get them off .
not to keep them off for long. thanks for any advice

I haven't tried it yet, but plan on it this year.

Diatomaceous earth

If traditional chemicals are not an option for you, there are several good organic products such as EcoSmart line. You can also use an IGR such as Nyguard which can be used pre-flea season as an Insect Growth Regulator.
