I’ve had problems with these buggers for a long time, I don’t know if it’s fungus gnats but these little fellows like to put larvae in my flower pots and I have tried every trick in the book…
Killing them each time I see one…
Use water with some vinegar and soap (it does attract them but they reproduce faster than they are dying) and change soil – I have not tried putting sand on top, apparently this will suffocate the larvae and make the plants less interesting for the flies to lay their eggs in.
There was a time I only found one fly in total, they seemed to have died (after I had located what flower had been infected to the max and sprayed it almost to death with green soap (I was desperate))!

I had once planted a garlic, it grew nicely until they actually made a LARVAE NEST inside the actual garlic! These larvae seem to love garlic, lol. It was a horrible experience seeing all the larvae which looked more like translucent worms with something black in them, crawling around the garlic root and eating it from the inside. Ugh… *shivers*

But now they are back, more than ever and they rapidly increased when I bought three new plants from a flower shop (eggs or larvae probably came with all of them – you could think they actually try to defeat these buggers in the store but it doesn’t look like it!)

I ordered a bag of nematodes (Steinernema feltiae) and put it into water and watered almost all plants (one bag wasn’t enough – I probably used more than I should have in each pot).
The results will be very interesting, I can’t wait to see these f*****s gone o_O.

My “sweetie” is VERY tolerant of my worm hobby, and he shrugs off the flies that have emerged from my bin that hve the worms from the farm manure. I know for a fact, that he would not be impressed with a bloom of fungas gnats. I’ve had them in houseplants before and they are a big pest. Having 4 bins in an apartment (!) I am always on the lookout for unwanted pests and not overfeeding to ward off potential problems.
Like a “apple” I would like to know where you purchased these good bugs in case I have a need for them in the future.

LOVE your site!

do you have a recommendation as to where to find nematodes?
