Mosquito Bits is a good product. You can find it at almost any chain hardware store in the US, not sure about outside the US though. It is a bacteria (Bacillus thuringiensis subspecies israeliensis also known as BTI) that controls the larvae stage of gnats and other water born insects (like mosquitos). Simply dissolve it into whatever water you use to hydrate your cakes (if hydrating coir blocks use 1 quart less of boiling water and when cool add the 1 quart with BTI to field capacity) and in your spray bottle if using one. It is entirely harmless to humans or other animals. Alternately you can use a 4:1 water to 3% hydrogen peroxide to mist with. This will kill the larva as they hatch in the substrate but can damage existing fruits so don't spray in a fruiting tub. Gnats are attracted to high moisture content. If you don't want to go the above route, try running less field capacity. Too often people will believe they are at the right point but are oversaturated, and the gnats will definitely tell the story. If you grab a handful of substrate and squeeze it hard there should be only a couple drops of water expressed... a stream or multiple dribbles is too wet and can become a gnat breeding ground.

Fans. Mosquitos and most other small insects will not be able to withstand the turbulence of the fans to land on you safely. Picaridin Spray - Picaridin, also known as icaridin, is an insect repellent which can be used directly on skin or clothing.[1] It has broad efficacy against various arthropods such as mosquitos, ticks, gnats, flies and fleas, and is almost colorless and odorless. A study performed in 2010 showed that picaridin spray and cream at the 20% concentration provided 12 hours of protection against ticks.[2] Unlike DEET, picaridin does not dissolve plastics, synthetics or sealants,[3] is odorless and non-greasy[4] and presents a lower risk of toxicity when used with sunscreen, as it may reduce skin absorption of both compounds.[5] Mosquito Bits - as others have said, this is incredibly effective and although you have stated you have no standing water in your yard, I would recommend walking around your property immediately after a heavy rain to see where you may have some hidden water pools. I also may or may not yeet a bunch of these bits into my neighbors yard as well.

TL;dr - Water your plants with a "tea" made from Mosquito Bits and consider replacing window screens with a denser screen mesh gage. Between buying some new plants and getting fruit from a farmers market a few years back, my home went from being "annoying gnat free" to fully infested (to the point where I was killing 20-40 of them per day by smashing them on the windows -- gross!). I went through a few home remedies like the apple cider/red wine/dish soap route and yes, while they killed the adult gnat/flies that were flying around, it wasn't killing their larvae. So for a few years I kept killing the adults but the little buggers kept coming back. Eventually I tried something called Mosquito Bits and used that each and every time I watered my plants. It took a while, but it definitely made a more sizeable reduction of the little buggers flying around. During the winter months there were zero adults that could be seen! But during the summer months ... they came back. I was really confused by this seasonality of the annoying gnats! Until one day ... when I saw a little bugger scoot its way through the mesh netting of a window screen and get its self positioned between the screen and the glass window pane! Uggh. Those little buggers are so little they can enter your home on warm days/nights when you have your windows opened! I'm at the point now that I want to try replacing my window screen with a more dense window screen mesh weave, but haven't quite gone down that route yet. The benefits would be less likelihood of the annoying gnats, pollen, and dust from entering my home, but the view out the windows will be a bit more occluded. Might be a small price to pay, though.

Here’s a link for the mosquito bits and I put them in these tea bags which makes it really easy when making the water. You soak 4 Tbsp per gallon of water (each teabag fits 2 Tbsp) for at least 30 mins and you use that water to water your plants. It does take 6 waterings before they’re completely gone. You can also try to take the first couple of inches of soil off and replace just that. My understanding is the eggs are in the first 1-2 inches of soil. I know it’s terribly frustrating and they’re annoying af but don’t give up. You’ve got this.
