Okay so a few weeks ago my girlfriend's flowers or whatever was inside the house and i noticed a little bug with wings come to the surface when i watered her plant. I looked it up and its a fungus gnat. I removed her plants from the house immediately. I also had a water leak issue with my washing machine discharge hose, which will cause them to stay in that area as well. I got all the causes fixed. But earlier when i was feeding, it seemed like i caught something in the corner of my eye fly by me, but it was small. Assuming the obvious, i dug my finger about 1/2 inch deep into the coco in each pot (i have 3), and in one of the finger holes i saw a super tiny White larvae thing. Im assuming thats fungus gnat larvae..
Ill say this before it even gets brought up. Im definitely not over watering. Im watering once to twice a day in coco (normally once a day), i have decent amount of perlite for drainage, fabric pots, and they are elevated. Runoff also gets drained so that i avoid problems with standing water, such as gnats...
How do i get rid of these bastards? I could put sand or dry coco on top of the medium, but i feel like theyre gonna eat my roots either way if i dont get them out of there with a pesticide of some sort. Im like 3 full weeks into flower with autos. Any suggestions? Thank you
