So I finally seen the dreaded fungus gnats . I read in othe post that mosquitos dunks work but is it ok to spray the leaves by accident? Also are fruit flys a concern cause they are everywhere in my grow room . I just notice roots on most my cuttings so I'm a little worried . Can't tell you guys how excited it is to see roots on 100 % of my cuttings . My wife calls me obsess cause I keep checking on them lol.

Oh ur lucky with cuttings mine aren't doing anything.

there is a product on ebay called gnatrol its an organic bti larvacide. works wonderful for gnats and its cheep. gnats will kill your trees and young rooted cuttings as they lay their eggs in the soil. the transparent worm like lava will eat the roots along with any other organic matter. once you see gnats then you already have more than enough larva to kill your figs and or other plants. gotta act quick.

Oh ok but isn't that the same ingredients as the mosquito dunks ? I didn't know they were that harmful to plants seen only a few

Neem works good on leaves not sure about the soil for gnats. I know some who have used neem with soapy water on the soil surface for mites.

Gnats are no joke. One year I lost close to 300 hundred cuttings that were already rooted and growing in cups. It was that that led me to gnatrol.

I lost half of my rooted cuttings to fungus gnats last year, but saved four trees by using Bt. The adult gnats aren't the problem. They lay eggs in the soil, then the larve eat the roots and into the cutting itself (gross!). You'll see tiny whitish worms munching on your cutting if you pull it out of the soil. Get a bottle of ready made Bt (kills all catepillar larve, nothing else), and spray until it wets the soil really well. Next, make sure you make it inpossible for adult gnats to reach the soil again. Apply a layer of sand on top, then plastic wrap around the base secured with a rubber band. You have to spray every 4-6 days I think...check the Bt directions. This worked for me, hope it helps, and best of luck!

Ok will do asap .
