With the coming of autumn, it is brown marmorated stink bug season once again. We’ve put together the information you’ll need to handle any calls that might come your way. A year ago, here in the Michigan State University (MSU) Extension Director’s Office, our phones were ringing off the hook with people calling to report sightings and to ask questions. This year, we’ll be ready. Use the following resources and websites to learn about the invasive pest yourself as well as give to any interested callers:
- The Midwest Invasive Species Information Network (MISIN) collects information on sightings of brown marmorated stink bugs but only in certain areas. Because the stink bug is well-established across the southern half of the Lower Peninsula, the network is no longer collecting information on sightings in this region. However, the northern half of the Lower Peninsula and the Upper Peninsula are regions that should report. For a comprehensive map of the current BMSB establishment in Michigan and the most up-to-date information, check out “Why and How to Report Sightings of Brown Marmorated Stink Bugs in Your Home or Business” by Julianna Wilson, MSU faculty member in the Department of Entomology.
- To report sightings in the requested areas, people will need to go to the MISIN website or mobile app, register as a user (it’s free) and follow the instructions for submitting a report.
- “The Brown Marmorated Stink Bug (BMSB): Information for Michigan Residents on a New Home Invader” by Paul Botch, MSU Department of Entomology, and Diane Brown, MSU Extension, goes in depth and covers background information, identification and eradication. This is a great resource to familiarize yourself with in order to answer questions. It’s also a comprehensive resource to send to anyone asking for information.
- MSU Diagnostic Services faculty member Howard Russell created “Managing Brown Marmorated Stink Bugs in Homes” about preventing and managing the brown marmorated stink bug in homes and in farms.
- If you have any calls from folks who’d like to have an insect identified, Howard’s “Tips on Submitting Insects for Identification” is an excellent resource on mailing a specimen or sending in digital photos.
Another common question we receive is if the insects are harmful to people or pets. Thankfully, they are not. If the bugs are harmless, why is this such a big deal? The brown marmorated stink bug is an invasive species that can cause damage to Michigan plants and crops, and the further we can track its spread, the more effective we can be in prevention and management.
