What can I use in my sump pump to control sewer flies? I see live larva floating on top of water.

I also have what looks like gnats on the bathroom floor & kitchen floor? Are these baby sewer flies, they do fly? Any help would be appreciated.

Answer:

We would suggest a product called Invade Hot Spot.  Invade hot spot is a foam in an aerosol can that you can apply to cracks in the tile on the kitchen and bathroom floors where the drain flies are breeding.  Typically this happens when there are cracks in tile or other places and water and grime get down in these cracks.  Fly larvae can breed in these areas.  You should treat over multiple days with the foam and it will eat the "gunk" in the cracks which should eliminate the breeding locations.
