What bug is this?

Asked June 22, 2020, 12:44 PM EDT

I have noticed a few of these bugs before but I came home from a weeklong trip and I now see approximately 100 concentrated next to my front window and door. They are pure black on the back with a lighter color on the stomach. They have wings that are barely noticeable. I live in Utah county. Please let me know what type of bug this is!!!!

Hello: That is a nuisance pest called elm seed bug. It does not harm plants or humans, but it does congregate on structures and can come indoors during hot periods of the summer, seeking shade. It feeds on elm seeds.

Below are links to more information, including some management tips (which basically includes elm removal, vacuum up the bugs, seal all cracks and crevices to the house):
