Bats provide major ecological and economic benefits in Minnesota. They consume thousands of insects each night, including mosquitoes and crop-damaging beetles, reducing the need for chemical pesticides and helping farmers save money. Species like the little brown bat and big brown bat play key roles in controlling pests, while the hoary bat helps maintain healthy forest ecosystems. Their guano also enriches soil, supporting plant and wildlife health.
Homeowners can protect bats by installing bat houses on buildings or poles at least 12 to 20 feet high, facing south or southeast to capture the warmth. They can also reduce pesticide use, preserve roosting sites like old trees or barns, and avoid disturbing bats during summer maternity season or winter hibernation. Creating bat-friendly yards with native plants and nearby water sources also supports bats.
