I sprayed two bottles for the second summer application of Cutter Backyard Bug Control Spray last night at 7, I sprayed all hard surfaces, the fence the siding, flower beds, lawn, and into the very wet forest as well. Mostly I use this every summer to get rid of mosquitoes, ants, and fleas. I have never had much of a problem with those since using it twice in the summer. But the MOTHS ARE GONE from the bushes! Remember, Cutter will prevent all insects including beloved Bumble Bees in your yard as well. So weigh it out since I have a very shady yard with few flowers for bees and butterflies, I'll take the trade off to save my sod.
I sprayed the Cutter about 10 days ago. I didn't see anymore moths for about 5-6 days, then they came back. I used 2 bottles of it, 1 in the front yard and 1 in the back. I've got 2 more bottles ready to go and may just try using 2 bottles in the front and 2 in the back. Even when I use Cyonara, the directions say 1 oz per gallon and I usually use 1.5-2.0 oz per gallon.
Maybe I am contributing to the "cause" but I have been also been spreading fertilizer (Hydro Phos) pretty regularly. I don't see any really bad spots in my yard, but knowing that I have those stinkin' sod worms and moths, I'm trying to keep what good grass I have, alive.
The pesticide, either spray or granules stay in the soil. My guess and my hope is that when the caterpillar hatches out of the egg it dies from the pesticide at ground level. I have never had lawn damage. but I have seen the moths. So maybe this works because I have always use bug granules and Cutter combination even before there were infestation of Sod Webworms. My neighbors have but got to it before they killed their lawn. If you see dead grass, it's too late. They have done the damage. The idea is to keep ahead of them. Again, my focus has always been against fleas, ants, and mosquitoes.
Out of the 16 houses on my short street (it's a "U" shaped street), I am the only one that does my own lawn - the rest have lawn crews which I personally think are bringing them in from other lawns on their equipment. I may be fighting a losing battle.
