That looks to be the hunting wasp Pseneo punctatus. During the warm seasons it hunts leafhoppers and stores them in nest cells to provide food for the young wasp. A sheet on this insect is at: https://webdoc.agsci.colostate.edu/bspm/arthropodsofcolorado/Pseneo-punctatus-leafhopper-hunting-was...

This insect appears indoors when potted plants that were outdoors in the summer are brought inside.  This insect nests in soil and will often nest in the soil cracks of potted plants.  Normally the adults emerge in late spring.  But when brought indoors they emerge months prematurely.

This wasp is harmless and the problem will ultimately end on its own as the wasps emerge, then die without reproducing.
