Hi all,

anyone know of an equivalent to mosquito dunks, or if in fact mosquito dunks are reatailed in the UK? Those yellow traps don't seem to be working.

Ta muchly.

also you need to remember that gnats are a symptom of your soil being too wet for too long - so ease off on the watering and let the top of the soil get dry inbetween.

Ive had fungus gnat probs on and off for a while, my planst at present have 2" of sand on the top of the soil to keep the little b******s at bay.

I havent tried horticultural soap yet, but i will be buying some of this to try for my next grow i think.

These are multi-purpose, but it says they are designed for sciarid flys, which is what i believe fungus gnats are.

The gnat off does look pretty good too, though i think this may work in a similar way using nematodes rather than fungus.

Thanks, managed to find it for a tenner. Can't ease up on watering, my plants are hungry. I mentioned those yellow fly traps not working, I tried pure orange juice in tubs, it goes gooey under the lights and catches them. Just need to kill of the larve now with bug of when it arrives.

You got gnat off for a tenner ? no way dude, if i was you i'd buy a hundred bottles cos i never seen anyone sell it for that price,

gnat off holds um back , but a nemitode drench is a cure and easy to use

Thanks guys, ordered the cheaper stuff, asked before about those mosquito dunks but unavailable in the uk so hopefully this stuff will do the job coz them little bastards really rape your plants, very destructive. i will report how the stuff does in a thread when i use it.

Ive tried a fly traps & "Gnat off" they control gnats but doesnt eradicate them. Then I went for natural predators, Hypoaspis did the job. If you cant find them cheap them PM me.

australian so probably not too good if in a hurry,but sounds good.

 

[bigwity]

i put a fan blowing over my pot tops it stops them landing

 

[dawgsbolloxs]

ive used greenfly killer from bayersgarden products with good success on small pots/rootd cuts ...B&Q

I was reading the organic gardening catalogue the other day and i noticed they had a predator for Fungus Gnats (Sciard flies,Fungus Flies) called Hypoaspis, it says the adults and larvae on the larvae of the Fungus Gnat, it says one treatment lasts 4-5 months, so that should be plenty long enough for almost any grow.

Nilnat works. I had a heavy infestation and now I don't, I use a little every watering. I've tried neem compost, keeps them away for about 4 weeks, neem oil wasn't too good, but it's worth using in conjuction with nilnat to spray the top of the soil to pick off any adult gnats and sticky fly traps.
