The only good flea is a dead flea. In a couple of weeks we'll be moving into our new country place. [img]/forums/images/icons/smile.gif[/img] The former owner had 4 or 5 dogs, which were kept in two compounds. One was fairly small - about 10 x 15 feet or so, the other was a large fenced area, perhaps 40 feet in diameter. We plan to demolish the smaller compound. The fenced area is going to be a play yard for our little ones.

Since it's almost certain that there are fleas in the ground in both places, how do I go about killing them, and their eggs? I want something that will not leave toxins behind.

Any suggestions?
