The CB PCO Fogger with Pyrethrins will kill the exposed gnats, but it will most likely have no effect on their eggs. The eggs are usually protected because of their hard shell and because they are placed into voids, cracks, crevices and other protected areas where the fogger is unlikely to penetrate. If you suspect that the gnats are breeding and laying eggs indoors, you should try to find the area that they are depositing their eggs. Depending on the type of gnat you are dealing with, they could be developing in drains, soil in potted plants, organic buildup in the bottom of trash cans, debris under appliances, etc. In most cases, a thorough cleaning of the infested area is needed.
