Onslaught is labeled for a wide variety of small flying insects including gnats, midges and other small biting flies and should help reduce the amount of noseeums on your property. Be sure to spray the areas where you have noticed the noseeums landing or resting as Onslaught will only eliminate those insects that land on treated areas. You want to dilute it 1oz per gallon of water.
