Fungus gnats are also an issue if you keep indoor plants.
I recently discovered that you can water your plants with mosquito dunks in the water, which will put the bacteria (aka: BTI, bacillus thuringiensis strain BMP 144) contained in the dunks into the soil. The bacteria then paralyze the larvae growing in the soil and they die.
Doing even more research, it seems there is a newer strain of the bacteria (AM 65-52) that you can buy in 16lbs! buckets for $570 off Amazon (or people have broken it into smaller batches on ebay).
This stuff really works like magic. Once the adults die off, no more appear.

- hahajk 3y agoI remember reading that fungus gnats are a sign you're overwatering your houseplants. (Water uptake is correlated with photosynthesis, indoor plants don't get or usually need much light). I just did a quick internet search and it looks like the popular advice for fungus gnats is still the same - water less. It'll also prevent root rot.
- latchkey 3y agoThat certainly helps, but doesn't really solve the problem. With that logic, every time you water, even infrequently, is a chance for them to come back.
- javajosh 3y agoI have to say that excitedly waiting for Amazon to deliver 16 lbs of bacteria makes me want to laugh/puke/write a screenplay for black mirror.
- sshanky 3y agoThis definitely works for me. One of my favorite solutions. I used to have a bottle of concentrated bacteria but I don’t know where to find that any more. Now I get something called mosquito bits and let them soak in the water I use on the plants.
