Gnats on my Aloe Plant
I noticed I have gnats that buzz around and are crawling on my aloe plant.
Are they harmless? Should I kill them off? If so, what can I use? I don't want to kill my aloe plant.
The plant is indoors, and in a terra cotta pot. I give it a 1/2 quart of water every week. The pot is well drained, with two inches of gravel at the bottom.
