Jewel Beetles

Asked June 12, 2017, 4:04 PM EDT

We have a small log cabin in Aitkin, MN that is about 5 years old. For the last few years we have had issues with what we sure is a Jewel Beetle boring holes mostly around the outside but occasionally on the inside. We have about 6-10 new holes a week and wondering if there is a safe pesticide or another way to prevent these beetles from making our cabin home? Right now we just fill the holes with caulk and remove the beetles if we see them.

Thank you for the question. Without a good close up photo of the insect and the damage for identification, we can't reply with specifics. Please read our publication on wood boring beetles and their control: https://www.extension.umn.edu/garden/insects/find/nuisance-wood-borers-and-seed-insects-in-homes/
If your beetle is one of these, note that you are managing the situation correctly and they will go away on their own.

Thank you for contacting Extension.
