I've got a huge Fungus Gnat problem, and It's starting to make me mad. Here is what I've tried so far: I tried the Hydrogen Peroxide method of control - Not all that successful. On the House Plant Forum it was suggested that yellow sticky traps and Mosquito Dunks left in your watering can will eventually rid your plants of the nasty buggers. Well it has been 2 weeks and I've seen very little difference in the numbers of Gnats. You can see be this picture (not very appetizing is it) how many Gnats are involved. On the back of the card you can hardly see any yellow left. There has to be at least 300 on there. The plant that is infested the most is my multiflora, and there is a lot of Coir in the potting mix. I don't know if that is contributing to the problem or not. Does anyone here have any other suggestions as to what else I can try? I really want to rid myself of these nasty things. I'm open to any and all suggestions including chemicals.
