Recently a bunch of my plants are getting infested with what look like gnats, and I'm assuming what are their babies. The gnats are very small and black, and the "babies" are even smaller and green. I've been spraying my plants with neem oil, since I've had success with neem oil for lots of other things, but it doesn't seem to be working. I've attached a picture of the pests. Hopefully you can see it. My camera isn't super great.

I think it is aphids. Fungus gnats don't bother the plant material, they fly around and lay eggs in the soil.
Might try washing them off with plain water.
i'm pretty OK today, how are you? ;^)

Unfortunately washing them off doesn't seem to be helping much. They just come back, and now a few of my plants are looking pretty sickly. Are there any sprays I can use, or something like that?

Yes, aphids. Washing them off does work but you have to make sure you wash the aphids down the drain. Insecticidal Soap works also if you want to try something a little more deadly without killing yourself in the process (and you don't have to get them down the drain). You will have to keep spraying as they will be back.

Are your plants in the house? My aphid problems are usually done with our first hot, low humidity days so I am surprised you are still having problems.

Yeah these are on house plants for the most part. I had some on my potted plants out on my patio, but as you said, they seem to have gone away since it's been really hot and dry. But the inside plants are still having a problem. If I keep my inside plants outside for a few days, will that get rid of them? I might try that.
