Is there anything there I can use at home dept to get rid of fungus gnats before they drive me fucking crazy?

You have Home Depot in Switzerland...?

Look for yellow sticky traps.

Do you have any Hydroponics stores near you? That might be a better place to look than the local hardwares stores. Of course if you don't and it's a real pinch you can buy something that is safe for use on fruit and veggies. Just make sure to use it as directed, spray with lights off to avoid burning, do it as far away from harvest as possible, and give a good flush before collecting end product.

I had to buy something called "GoGnats!" recently and I found it at a local hydro store or Neem oil.

Ya better get something fast. They will fuck your shit up. Trust me i know. Start by letting your soil dry out more before watering. Thats where they come from over watering. Get on it. They will hurt your plant. They will turn yellow.

try no pest strips i used them and they work awesome left it in for four days and problem solved and u dont even have to spray ne thing works awesome

what about the larvae in the soil though if I buy traps they will just keep coming back through the soil...Yea I need to find something there to kill the larvae also and not harm my plant

just a side not does anyone know where i can find the link to the youtube video of the guy who did that bad ass outdoor grow in BC...It was a decent 4 min video. I dont remember his sn though but he blocked out his voice and drove into the woods and had to carry a bunch of shit to get it setup

If they get caught by the traps after hatching and getting their wings, then how do they get to lay their eggs in the soil

I just use pyrethrin spray, because I have other pest issues that sticky strips won't fix.

Like black widows.

Try Gnat off, it can be used as a soil drench ans always does the trick for me, Ill have a look wats in it (Active ingredients) and let you know so you can get something similar if you cant find gnat off.
