What is this bug?

Asked November 8, 2017, 1:40 PM EST

Good Morning,

We are experiencing lots of new bugs around our house this fall.

They are about a third the size of a mature Boxelder bug and similar in appearance. We have always seen Boxelder bugs here in Grand Junction around this time of year.

These new bugs are small enough to get around the screens and are in most of the windows of our house. They have a distinctive odor if disturbed. I've been using the vacuum to collect them in the house.
Are they something we need to worry about? Are they laying eggs in the house? Is there a good way to get rid of them?

Thank you.

Hello Pete,

It is an elm seed beetle. It is new to our area and just a nuisance. Caulk if possible and vacuuming is a good move. They are just trying to find a warm place for winter. They will do no harm.
