Fungus Gnats! Help!
Comments (17)Sounds like you have a few good suggestions, Blossomgirl. One option that I haven't heard floating around is to simply repot. No chemicals needed. The larvae live in the medium. No medium, no larvae. You can also use a horticultural oil or insecticidal soap as a drench, and that should kill larvae and adults in the medium alike. The key is also to run your plants drier so you kill off the larvae that thrive in moist environments. I would also like to correct a couple misconceptions I have read in this thread: 1) the larvae do NOT eat orchid roots or algae. They eat the fungus in the soil, nothing more. hence their name Fungus gnats. Proper treatments for commercial production always include a fungicide. 2) the presence of gnats does NOT necessarily indicate that the medium is too wet. Gnats are resilient little buggers and survive on less moisture than you think. I've had plants stay bone dry for a couple weeks, only to water and have them still be there. They can be pretty difficult to get rid of. The "too wet" mantra is a bit outdated, especially when you consider there are a lot of plants , like spathiphyllums and caladiums, whose preferred moisture level is definitely on par with ecology of gnat larvae. It makes sense if you have gnats on a cactus or other dry-thriving plants, but not with the majority of other plants we have in our collection...See Moreplease help....I got my first fungus gnat and I don't why

Comments (8)The soil is a mix between MG General Potting soil and a cactus citrus mix for drainage. I water them 2-3 times a week very lightly ( generally little to no water comes out the bottom of the pots). I only fertilized them once lightly about three months after they had started growing with a liquid fert mix from "organic choice?" The fazli is about a foot and a half from the flourescent light and 2-3 feet from the 60watt incadesent light, which I only started back up yesterday, my last bulb burnt out 2-3 weeks ago. The little tiny haden (i believe) is 2 feet further away. The flourescent light is on from 7:30am until 7:30 pm or so with a few breaks during the day. The incandescent light is on intermittently between 10:30am and 3 pm. I live currently in upstate ny, st lawrence county (zone 3a-3b). How would you reccomend acclimating them to the light. And I've also read that mangos are very susceptible to salt burn, should I consider leaching the soil?...See Moreplease help - fungus gnats eating bulbs?
Comments (2)Fungus gnats eat the roots. I'm not sure how many you have but try letting the soil dry out a little before watering again....See Moreshiver
