Hello everyone! I was hoping I could get some advice for fungus gnats. I had purchased contaminated soil from a big box store, big mistake. Any way long story short I have used sticky straps in my plants. I got rid of most of them but it’s been a couple of years and I can’t seem to get rid of them completely. Any advice is truly appreciated!
Hello! There’s a multitude of things you can try from Mosquito Bits (sprinkled on the soil, systemic) to watering thoroughly with a solution of peroxide and water (1 part peroxide, 4 parts water). Neem oil pretty much does nothing besides smell. If the plants can tolerate it, wait to water when the soil is dry. Fungus gnats need moisture for their eggs and larvae in the soil. In my personal experience, I moved away from using soil and use my own medium mixture. To get rid of the existing annoying pests, I purchased a Mexican butterwort that decimated the adults in a week. If you find them locally, get 2 or 3, place them in locations where the infestation seems the worst and let them work.

좋아요 1개 I’m happy to help! Like Elon mentioned, sterilizing the soil works, too. I’m not sure how I forgot that. I think it can leave an odor (although not long lasting).

Bunny’s advices are great. I also want to add that if the new soil is contaminated with fungus gnats you can sterilise it before you use it. By applying heat to the soil you can kill the fungus gnats in the soil. Boiling water, microwave or oven are known to use when sterilising the soil ☺️

Hey! My fungus gnat recommendation is adding the mosquito bits to soil, sticky traps, and cinnamon in the top of your soil! Good luck

좋아요 1개I used nematodes to get rid of my fungus gnat infestation. Haven’t seen one since I treated, I’d say it was completely successful!
