Bats are important for the ecosystem, no doubt. But when they start roosting under your porch or hanging out near the front door, they can quickly become a frustrating problem for homeowners in Michigan.
Whether it’s the unsightly guano buildup or the surprise flutter of wings when you step outside at night, bats roosting where they shouldn’t be can disrupt your sense of comfort at home.
While it’s never a good idea to harm bats, keeping them away from living spaces is important for safety and cleanliness. Bat droppings can carry diseases, and having bats too close to your home can lead to unwanted noise, mess, and potential health risks.
That’s why many homeowners look for simple and humane ways to keep bats from settling near entryways and porches.
If bats have started nesting around your entryways, it may be time to think about pest control strategies that are safe for both your home and the environment. Here’s what you need to know about how to deter bats from your porch, and what works.
Key Takeaways
- Seal small gaps around your porch to keep bats from roosting in hidden spots.
- Use safe deterrents like lights, shiny objects, or mild bat repellents to make your porch less inviting.
- Remove attractants by turning off porch lights and cutting back trees near your roofline.
- Call a pest control pro if bats keep coming back or get into your attic.
Why bats love porches
Your porch, especially if it has overhangs, eaves, or exposed rafters, offers the kind of sheltered environment bats look for in a roosting spot. These protected areas mimic the natural crevices they’d find in caves or trees.
Your porch also tends to be near food sources because flying insects are drawn to your porch light at night. That combination of shelter and snacks makes your front porch pretty appealing.
Signs you have a bat problem
If you’re seeing bat droppings (also called guano) on your porch railings or deck furniture, it’s a strong sign that bats may be roosting nearby. Bat guano is small, dark, and crumbly, often confused with mouse droppings.
You may also hear scratching or chirping sounds at dusk or see bats flying out from behind soffits or shutters as the sun goes down.
Even one bat can leave behind droppings and noise, which can be a problem, especially if you have pets or young children playing outside.
Step one: Seal up entry points
The most effective long-term strategy to get rid of bats and keep bats from returning is exclusion. That means figuring out how they’re getting in and sealing those spots once you’re sure they’ve left.
Look for tiny gaps around beams, under eaves, behind shutters, or in decorative trim. Even a hole as small as ½ inch is big enough for a bat. Use caulk, mesh, or weatherproof foam to seal these entry points.
If you’re unsure whether bats are still inside, one-way doors can help: they allow bats to exit but not re-enter. Just make sure to remove the one-way doors and seal up the hole after the bats have left.
DIY bat deterrents: What works (and what doesn’t)
When it comes to keeping bats off your porch, some DIY tricks are worth trying, but not all of them hold up. Here’s what to know:
- Bright lights: Bats prefer dark, quiet areas, so installing a motion-activated porch light can make the space less attractive. Keep in mind, though, that more lights can also draw more flying insects, so this might make your porch brighter but also attract more bugs.
- Mothballs and peppermint: Some homeowners swear by these, but their effectiveness is hit or miss. Bats may be temporarily deterred by strong smells, but they often return once the scent fades.
- Aluminum foil or mylar balloons: Hanging these near the roosting site can create reflections and movement that startle bats. It’s more of a short-term fix, but it’s safe and easy to try.
- Wind chimes: Like shiny deterrents, these rely on noise and movement. They may work best in combination with other methods.
Some homeowners also try commercial bat repellents, but results vary. These products may offer short-term relief, especially when combined with other deterrent methods.
Don’t give them a reason to stay
If you’re serious about keeping bats off your porch, you’ve got to remove what’s attracting them in the first place:
- Turn off your porch light at night or switch to yellow “bug lights” that attract fewer insects.
- Eliminate standing water, which can draw insects (and in turn, bats).
- Trim back nearby trees that offer easy access to your roofline.
Should you install a bat house?
It might seem counterintuitive, but one way to keep bats away from your porch is to give them somewhere better to go. A properly placed bat house can lure bats away from the spots where they don’t belong, like your porch.
Mount the bat house at least 10 feet off the ground on a building or a pole, ideally 20 to 30 feet from your home. Keep it out of direct light and away from regular human activity. You might not get bats right away, but over time, they may choose the bat house over your porch as a roosting site.
When to call for professional bat removal
If you’ve tried DIY deterrents and bats keep returning, or worse, if you suspect a bat infestation inside your attic or walls, it’s time for professional help. Bat removal isn’t just about eviction. It requires a humane and legal approach called bat exclusion, especially since many bat species are protected.
If bats keep returning despite your efforts, consider calling a pest control expert who specializes in humane bat removal and exclusion.

Final thoughts
Keeping bats away from your porch starts with understanding what they want and removing it. Whether it’s bright lights, blocking entry points, or installing a bat house nearby, a mix of deterrents can go a long way. And if bats still won’t budge, you know who to call.
Successful bat control often means using a mix of techniques, sealing entry points, reducing insect activity, and offering alternate roosts like a bat house.
