I also use the AdvantageII yard spray to knock them back. We haven't seen a flea yet this spring, and only 1 tick, and it was on the cat.
We have had quite a lot of rain this year . . .I am seeing little flies that I have never seen before. They don’t look like your normal fly. I hope this isn’t the beginning of one of the plagues that God is promising in the end times. Some weird stuff going on.
