You can neem seedlings. Don't put them under any direct light until they are totally dry or they will burn badly.

For fungus gnats you can get BT mosquito bits or crush up BT mosquito dunks and sprinkle them on the soil when you water. That will kill off the larvae and break the reproductive cycle.

^^^ like @bam0813 says.

For neem to do anything, the bug has to eat it. The adult gnats don't feed on the plant. The adults aren't the problem. They're just an annoyance. It's the larvae in the soil that do the damage.

You've got to break their reproductive cycle.

You're probably keeping the grow medium too wet.

And like @bam0813 already said. Spraying the plant won't do anything with fungus gnats.

Adjust a fan to blow over the tops of your spots. Sticky pads will kill the adults and letting your soil dry out will help. You're keeping them too wet.
