High Rock Beagles, I use Ortho Max too on our entire yard and I don't have fleas either. My wife just put out some of it on a few ant hills as well.I don't have fleas. I've been treating the ground with orthro max or equivilant for the past 20 years. I use a big bottle of Happy Jack dip makes 30 gal. Add 1 bottle of kerosene to it and 1 box of cooking salt and stir for ticks. Dip dogs every 2 weeks. Works great repels mosqitose well too. Use it all season.
