We recently moved to Utah and live in Uintah Highlands. The past couple of weeks we have noticed an incredibly high concentration of a black and red beetle looking flying insect at our windows and on our house. When I say high concentration, I mean too many to count. We are not familiar with these insects and are wondering how we can get rid of them.



USU Extension has a Fact Sheet about Boxelder bugs. You can find it at this link: http://extension.usu.edu/files/publications/factsheet/ENT-41-06.pdf

These bugs are very difficult to control. Fortunately, they don't harm people, homes, or plants. But they can be a terrible nuisance.

One suggested control is to drown them. Line up some plastic trays underneath the wall where the bugs are congregating, then spray water down the wall so that the bugs are washed down into the trays of water. Because they don't swim well, most of them will be trapped and drowned.

To keep them out of your home, seal all cracks and crevices. You can use sticky traps in windowsills to help catch some.
