This time of year I have generally have loads of mosquitos in the backyard. Really a nuisance where you're trying cook out, or just chill on the deck. I came across a product that really worked wonders for me. It's called Cutter Bug Free Backyard. It comes in a hose end spray bottle. I picked up a bottle at Lowes, sprayed my backyard and the results were amazing. The mosquitoes just disappeared. The label says its effective for up to 4 weeks, but I think it lasted about two or three weeks for me. The bottle covers about 5000 sq ft and costs about $8.00. I'm not associated in any way with Cutter, but I wanted to let you know about it and am wondering if others have had good results with it.
