Hello! I have a succulent that i’ve been taking care of for the past year. I went to water it today and I found a small insect that looks like an ant running around in its soil.
I then check the leaves and see there are more in there. Is this common, or harmful to my succulent? And how do I get rid of them without them coming back.
Things to note: I live in Massachusetts and its currently very hot outside (85 F) and it lives in my window cill with the AC on. I’m also new to plants overall.
