I have that one that looks like a badminton racquet but the gnats slipped through the webbing. I scored more with mosquitoes, which are bigger than gnats around here.

Cythan I am interested in the info about your bug zapper.

No Pest Strips will control a fungus gnat and fruit fly infestation.

Cythan, I realize it has been a while, but this post is the most helpful. We live in a wooded area, near a protected wetland, and also have a Guinea pig. We will be trying your insecticide, but also are interested in the bug zapper as well. Do you still have the information from the box?

I dont know about outside but inside the ole "apple cider vinegar" works like a charm for fruit flies. I put a little in a dish/bowl , add a drop of dish soap, cover with cling wrap and punch tiny holes for the flies to enter, they will go in but wont come back out. Place near where they are congregating even if its right on your worm bin . This does not work for gnats. Its also easy to tell which you have. Gnats are slow long legged fliers and fruit flies are fast fliers. It seems the FF are the ones attracted to the worm bins as they try to lay eggs in the food you put in thats why its important to cover with a nice layer of shredded paper each time.

I would like to no which bug zapper is best
