Hey guys,

Hoping you can help me identify this little bugger and how to deal with it...
I bought this pot with multiple succulents at costco a couple months ago and I've been keeping it indoors.

Last week I started noticing these little flies around and I was able to trace it back to the succulents. I was able to snap this pic:

It seems to be infested by now. I've killed a whole bunch of them (I use a handheld vacuum to suck them up and then give it a good shaking to kill them), but they keep coming back.
Based on what I looked up online, I think it might be a fungus gnat, but not sure.
It is very small (maybe about a quarter of the length of a grain of rice?).
What I saw online about fungus gnats mentioned that it's often due to overwatering, which makes sense because I did water it a couple weeks ago and I realize now it probably did not need it. There was a layer of moss over the soil which probably has contributed to the moisture. It's been indoors and temperatures have been "fall like" so not much drying out has occurred.

I have since put it outside (to keep it away from my other plants and to help it dry out). I also removed all the moss and dead plant matter, and I'll try to remove some of the top layer of moist soil.

I know that was kind of long winded, but... do you think it's a fungus gnat and if so, is there anything else I can be doing to treat it besides letting it dry out? And if it's not a fungus gnat, what is it and how can I treat it?

Thanks in advance!

Yep, fungus gnat. You can use Mosquito Bits on the soil or just let it dry out. For succulents the dry-out solution should be easy.

Thanks so much!
As I mentioned, I moved the pot outside to keep it away from my other plants and to dry it out.
Unfortunately, temperatures here have been in the low 60's during the day so it'll probably take a while to dry out. It looks like temps are supposed to drop tonight into the low 40's and then mid 30's the rest of the week (evenings). Is that too low for succulents? I really don't want to move it back indoors...

As long as it doesn't get below 35 you should be okay, but it's pushing it. If you have some overhead protection it will be safer.

Thanks again.
In the end I moved it upstairs to an unfinished room in my attic with a single east facing window so it will at least get some light. And this way it's far from any other plants and not much in there for the bugs to get to. Not much heat in there so will take a while to dry out, but at least it's milder than outside.

Well, heat rises so that may help a little. Thumbs up
