DNR Warns: Black Bears Can Squeeze Through Your Pet Door

Michigan's black bears are currently shopping for winter real estate like it's peak season on Zillow, and according to the Department of Natural Resources (DNR), your deck, shed, or unsealed crawl space is looking way too affordable. As winter creeps in, bears stop their 24/7 buffet routine and start seeking a snug spot to snooze — and if you're not paying attention, that "spot" could be the space under your porch where you store half-broken lawn chairs.

Why Bears Pick Your Home for Denning

BearWise, a partner of the DNR, says bears typically den in hollow trees, caves, or dense thickets — you know, normal bear stuff. But sometimes they look at your storm cellar or tire pile and think, "Wow. Open concept. Great airflow. Zero rent."

Here's something you may not know: bears don't have collarbones. Translation? An adult bear can squeeze through an opening the size of a pet door. Yes, even your pet door.

How Many Bears Are in Michigan?

The DNR reports we've got around 10,300 bears in Michigan's Upper Peninsula and another 2,100 in the Lower Peninsula. Many are still out foraging due to warmer weather, but the U.P. bears are hitting snooze mode early thanks to recent snowfall. Meanwhile, the Lower Peninsula is still racking up nuisance bear complaints.

Home-Security Tips from BearWise

BearWise suggests locking ground-floor doors and windows, swapping lever handles for round knobs (bears can open levers like seasoned burglars), and installing outward-opening doors. They also offer tips for scaring bears away — ideally before you realize one has claimed your shed as its winter condo.
