Fungus gnat experiment # 569

25 feet of noseeum screen with 20 x 20 mesh. A few bags of fat rubberbands. $30 for both.

After failing 568 times with poisons and potions, pots and bags, prayers and insults, I have decided to try and block their entryways. They love my 2 gallon pots with the 5 holes around the bottom that not only are open on the sides, but a bit of the bottom as well. You can always manage them on the top of the soil but they will annihilate you from the bottom and sides if they can get in.

I tried all the other stuff and gave up. Fabric pots kept them out of the bottoms but I hated using them. So now I tried this:

So far I don't think they can squeeze thru the holes. Their wings kind of block it. Been 3 days since transplant and no gnats yet. I will call this working or failure after a full flower or about 2 months of no infestation. As soon as I see one single gnat get thru this will be a failure. I can vac off the ones up top easily and all others get soaked with a good Cleanse feed from Athena. Always the ones on the sides/bottoms get away.

Water comes out very easily and holds nothing back so I got my fingers crossed with this experiment. Cheap too :blsmoke:

I thought of something like this I just thought theyd get thru any imperfection. So I thought maybe if the tent was sealed enough. They all have to be though.

Sucks to hear you tried so many things, feeling hopeless again about my gnat and or root aphid issue.

Then why the current effort?

BMC Microlift's active ingredient is bacillus thuringiensis israelensis (BTi), which is 100% effective in eliminating fungus gnats. BTi kills the larvae and breaks the lifecycle. It has no effect on adult gnats, so the process takes a few weeks until they're eliminated.

I commend your efforts, but it seems you missed the simplest, most effective, treatment for fungus gnats.

Is 8% the best concentration? Eyeing that. Didnt think it would be so cheap amd long lasting. Bought 60$ in mosquito bits but they failed to tell me using it per label causes white mold to form often times.

Which it did. Id be willing to add that to my reservoir dtw coco. Hopefully the 3ppm chlorine wont do too much to it but read it shouldnt.

OP did say they tried it though. I cant recall what I found with shotty research but I think I read others not having luck with it.

Learned on another thread to make sure its not root aphids which look similar and bti doesnt kill aphids. Just a fyi.

Also read drying back as much as possible helps and I saw less flyers from a mistake not feeding for 48hrs. Or was it the mosquito bits? They arent molding in some pots but can at any time.

I was thinking same thing OP thought of but like a bag shape that goes around the whole pot maybe just seal it off in the drippers amd main stem.

I much rather just use the liquid bti I just damn.. Aint got much to lose may as well spend another 20$ and try it. Yall convincing me. Hope to hear what OP has to say.

Ya you can use whatever you like medi. I was just posting an idea. Wasn't asking for advice. I think you know my answer about BTI. I said it in another post somewhere. Works on small controllable grows. If you have gnats anywhere else in the house they will just get right back in a week later and restart the whole mess again.

I said “similar to this” :-). I tried with 15 gallon fabric pots, and bought several different size and types of mesh covers made for protecting small outdoor fruit trees. I put the covers on the bottom, and tried to cinch them around the stems to keep the pots completely covered and keep gnats out. I also put the perlite layer on top to block them. It made watering a pain, and top dressing was even worse. They still eventually got in. I scrapped the idea and used the BT and some chemical-free sticky traps and fly strips gnats. Gnats and covers are both gone. Ted talk over

Again, I'm glad BTI worked for you and your humongous grow. Glad you worked it out with Ted as well. Whoever he is.
