I've noticed that my houseplants are infested with what I believe are fruit flies, and I suspect they're coming from the soil. Can anyone confirm if mosquito dunks are effective against these larvae? What's the best way to use them, and how much should I add per gallon of water?

Yes, they work on all types of fungus gnat larvae in the soil! Just make sure you’re using it correctly, and you should see results. It's one of the best treatments out there for this problem.
Definitely sounds like you're dealing with fungus gnats rather than fruit flies! Mosquito bits or dunks, which contain *Bacillus thuringiensis israelensis*, are effective for killing the larvae, but they won't address the adult flies or pupae immediately. Expect to see some continued hatching for about six days while those pupae come to fruition. To use them, mix a small amount—think of 4 M&M-sized pieces of the dunk or bits—in some water, let it sit overnight to activate, then water your plants with that solution.
That’s right! Just keep an eye on your plants, and you should see a reduction in the gnat population soon.
For sure! I've used them with great success on my indoor plants, and it's super easy.
