I have a gnat problem! I heard sprinkling a little bit of cinnamon on the soil will kill them. will it harm my plant?? if so whats some easy methods to get rid of them? please help!
i read you can use insecticide wipes to get rid of gnats. wipe around the edge of the pot and then put the wipe in the pot under the plant. i hope this helps!
You can put a peeled slice of potato on the top of the soil and it will attract larvae up to it. Just pick it up and look under it after a day or so and you should see some larvae that you can pick out. You should also buy some of these yellow sticky card traps to catch the adults. Put a couple near your plants, the yellow attracts adults and they get stuck and die, without using poisons! I think a layer of sand on the top of your soil will suffocate the larvae as well, if you wanted to try that.
