I wish it worked that easily with the gnats I have. They look like miniture flys but gnat size. Have used many different sprays for the inside of the house with no avail. The suckers seem to fly between the drops. They also seem to be immune to residuals on the walls.

Almost ready to get some of the pest strips for barns. I am aware there is a tie between them and several health problems but no 2 legged children in household.
