I live on 5 acres that I converted from farmland just south of San Antonio Texas. My property is very sandy. I have not yet been able to establish much grass. My wife breeds dogs for a hobby. We have about 20 dogs in pens outside. We have a terrible flea problem. My neighbor gave me a bucket of Agrevo Drione. It is suppose to be very good on fleas. Can anyone tell me about this insectide and how to use it.
