Consumer Products Lawn&Garden

I purchased above product to get rid of fleas in my yard. I initially purchased 2 bottles and used according to directions. Each bottle should treat up to 16,000 sqft. My lawn is 20,000 sqft. I ran out of product and bought 2 more bottles, using them properly. My inside dog, a Chihuahua, had 3x the fleas after I treated the lawn than she had before. I contacted Gro Tech July 25, 2008, demanding a refund, but they have ignored me. I just wrote another and have contacted the BBB. Don't buy their products. Their company is as sorry as their products. Guarantees in writing mean nothing to them. So far, I am out $39.15, plus two wasted trips to the store, plus my time.
