Mosquito Bits

When I came home to the gnat apocalypse, I bought some nematodes and mosquito bits. I used both in the next watering (soaked them through), then watered as normal with bits. The problem disappeared overnight.

I use a combo of mosquito bits with every watering and sticky traps, might also help to bottom water for a bit and/or remove the top layer of soil. The mosquito bits mostly helps with the larvae

with that many plants i would definitely use mosquito bits or predatory nematodes.

Mosquito bits work. They attack the larva so it takes time to see the end result.

Agreed. Mosquito bits are super effective.

Buy a bag of Mosquito Bits and make "tea" out of them, then water your plants with that and add some to the soil bag. ... I had a severe infestation about two years ago ..., used this method, and been gnat free since then.

I feel like neem oil and mosquito bits are the things I’m seeing most of for bug remedies.

Mosquito bits + hot water. Keep this for 5-6hrs then strain the bits n pour this water in affected plants as part of regular watering. Keep using the yellow sticky traps. This treatment should effectively kill both soil larvae n adult gnats.

For me, what worked was a combination of mosquito bits, beneficial nematodes, and sticky traps for monitoring.
