Bat Control in Wisconsin: When Bats Can Be Removed & What Homeowners Need to Know
Bats play an important role in Wisconsin’s ecosystem—but when they enter your home or attic, they can quickly become a serious problem. Homeowners in Green Bay, Appleton, Brookfield, Sturgeon Bay, and Wausau frequently deal with bat activity, especially during seasonal transitions.
At Erdye’s Pest Control, we specialize in safe, legal, and humane bat control, ensuring your home is protected while following all Wisconsin regulations.
🚨 Why Bat Infestations Should Be Taken Seriously
While bats help control insect populations, they can cause significant issues when they roost inside your home:
- Accumulation of bat droppings (guano) can create strong odors and health risks
- Guano can carry diseases like histoplasmosis
- Bats can potentially carry rabies
- Colonies can grow quickly if left untreated
- Bats often settle in attics, walls, and other secluded areas, making infestations difficult to detect early
🕵️ Signs You May Have Bats in Your Home
Common signs of bat activity include:
- Scratching or fluttering noises at night
- Bat droppings near entry points
- Bats flying near your home at dusk
- Strong, musty odors in attic spaces
If you notice any of these signs, it’s important to act quickly before the colony grows.
⚖️ When Can Bats Be Excluded in Wisconsin?
This is one of the most important—and most misunderstood—parts of bat control.
✅ Allowed Bat Exclusion Periods:
- Early Spring: Before bats give birth
- Late Summer through Winter: After young bats can fly
❌ Restricted Period (Critical):
June 1 – July 31
During this time, bat exclusion is generally illegal in Wisconsin because baby bats (pups) cannot fly. Excluding adults during this period would trap young bats inside, causing them to die.
👉 In most cases, safe exclusion is performed:
- Before June 1
- After July 31 (typically August–May)
⚠️ Why Professional Bat Control Matters
Bats are protected animals in Wisconsin, and it is illegal to kill them in most situations. The correct method is exclusion, not extermination.
At Erdye’s Pest Control, we follow all state regulations and use humane methods that protect both your home and the bats.

🏠 How Bats Get Into Your Home
