I have a 20 gal tank. How many oz of Demon should I add to treat my yard??
I have a 1 acre yard. I'm having a grasshopper problem this year. Nothing seems to work for more than a week. I was hoping Demon would last a little bit longer in the yard.
Demon will last up to 30 days on outside surfaces depending on the rain and sun exposure but is not actually labeled for grasshoppers.
Talstar P would be a good choice for grasshopper control and will last up to 30 days as well. You should start applications before the grasshoppers have a chance to hatch for best control. You should thoroughly spray your lawn and water in the application with about a .25 in of water to help the product get past the thatch layer and into the soil where grass hoppers actually develop. If you already have grasshoppers you can use Talstar P at the highest usage rate of 1 oz of product per 1 gallon of water for the quickest knockdown. Use sufficient amounts of water to help the product get to the soil layers.
