small black flies in soil & air pots

[stinkhairs]

Hi, i have these small black flies floating around my tent. I usually grow in 10 litres pots and whenever i've had them in the past, i just added an inch of sand to the top of the pot, but now 4 of my plants are in air pots, they come out of the soil from all the holes - what can i do to get rid of the buggers?

Any products, or home recipes that work would also be good

grind up about 1/2 a mosquito dunk on top of each pot; lay out some yellow sticky traps to get an idea of how bad the infestation is.

also put a chunk of raw potato on top of your soil; leave it there overnight and in the morning it should be totally crawling with larvae.
lay out some small saucers of red wine in your grow area the flyers will stop by to take a drink and drown in it.

you might consider buying some gnatrol; a product i stand by very much so and have had great success with eliminating fungus gnats.

Gnats love very wet places try not to over soak your soil MJ doesn't like it
there's a few good ways to get rid of them first one i would do is cinamin on top of soil , even mix a little in your food , pour it to them
secondly is cedar mulch place ceder mulch on top of your soil there a good insect repelling source
Also lastly you know them nice smelling kling wraps you put in your dryer to make your clothes smell nice place place them ontop of your soil this alone will repel them from laying larvae in your soil
just remember try not to water your soil to much meaning having it drenched try less amounts more frequently
hope this helps CHEERS DOC

i recently got rid of all my fungus gnats by laying a no pest strip on the top of the soil for a day.

I got rid off fungus gnats and haven't gotten them back. One, I do not use any commercial growing medium,seems whenever I bought soil from a store it came with gnats. Two, I use a vacuum cleaner and suck the little mothers out of the air. It may take a few times to get them all and as larva hatch you keep sucking them up. It takes awhile but it's totally non chemical. Anyone wonder if dunks chemicals ever enters your smoke via the roots. Personally I've become really picky about what I smoke or eat, I mean picky as what was used to grow that plant.

Dunks are a bacillus I believe.

I may hav stopped mine in hydro using Nematodes and sticky traps at my barrels. May being the word.

there's a constant influx of them via the sewer drains here. i put bti in my watering can. there's usually a few hovering around but no more plague proportions.

it's important to take them out. the larvae chew the root hairs.

i've made some interesting observations about them though. as destructive as they are, they will let you know if there's something wrong with your plants, if you're an insect whisperer.

one grow where they showed up after the plants got big enough to survive them, i noticed that certain buds here and there served as gnat burial grounds.. there weren't dead gnat bodies stuck all over the buds, just one or two here and there.

still, gotta take em out before they start using tools and using fire and stuff.

There is a biological way; around here there are lots of these small grey lizards, about 3 inches long. The couple of times I have had these fly things the lizards move into the grow and eat them all. Every single one.

Do they eat the larva also? Do they clean the bacteria from the fine hair roots. Do you have a species name?

I found a large Palmetto bug lounging in one of my seedling cups this morning. I really hate those things. I got like a phobia. I stepped on one barefoot once.

Oh, yeah battling those gnats also.

Thanks for the replies.

ha! at the moment their in the loincloth stage, still better to get them before they start touching a black monolith.

Mosquito Dunks sound promising but i'm in the uk, i don't think you can get them over here. I'm certainly not going to get some fucking lizard wandering around my grow room. Will try the potatoe thing and fly papers. I was surprised the carbon filter extractor wouldn't suck them up?

Funny you say about the soil, as it's canna terra professional plus, and at £17 a bag i wouldn't expect any contraband in it.

the potatoe and the sticky papers will only show you how bad the infestation is but it will do nothing to curb their numbers;

you HAVE to target the larvae somehow or else these damn bugs will haunt your grow indefinitely


you can get the dunks on ebay UK; they are legal in the UK. peace.

the wine or apple cider vinegar so i've heard. i can say from experience that white vinegar doesn't seem to do the trick.
