How to Keep Bats Away From Your Porch: A Comprehensive Guide

Bats are an essential part of our ecosystem, but they can become a nuisance when they choose to roost on your porch. In this comprehensive guide, we’ll discuss how to keep bats away from your porch while also respecting their role in the environment. We’ll cover bat behavior, legal and ethical considerations, prevention and deterrent methods, installing bat houses, and when to call a professional.

Understanding Bat Behavior

Before we delve into keeping bats away from your porch, it’s important to understand their behavior and habits.

General Bat Behavior and Habits

  • Bats are nocturnal creatures, meaning they are active at night and rest during the day.
  • They seek out dark, secluded areas to roost during the day.
  • Bats are not aggressive, but may bite if they feel threatened.

Reasons Why Bats Are Attracted to Porches

  • Porches offer dark, sheltered areas for roosting.
  • Insects, which bats feed on, are often attracted to porch lights.

Benefits of Having Bats Around

Despite the challenges they may pose, bats provide several ecological benefits.

Ecological Benefits

  1. Pollination: Bats help pollinate plants, particularly in tropical and desert ecosystems.
  2. Pest Control: They consume large quantities of insects, reducing the need for pesticides.

Misconceptions About Bats

  • Bats are not blind, although they use echolocation to navigate in the dark.
  • Bats do not intentionally tangle in hair; they are skilled at avoiding obstacles.

Legal and Ethical Considerations

Before taking any measures to deter bats, consider the legal and ethical aspects of bat removal.

Legal Restrictions on Bat Removal

  • Some bat species are protected by law, and it is illegal to harm or kill them.
  • Check your local regulations to ensure you are compliant with wildlife protection laws.

Importance of Humane Methods

  • Bats play an essential role in the ecosystem and should be treated humanely.
  • Focus on prevention and deterrent methods rather than lethal measures.

Prevention and Deterrent Methods

To prevent bats from roosting on your porch, consider implementing these strategies:

Removing Attractions

  1. Eliminating food sources: Turn off porch lights to reduce insect populations, or use bug zappers to keep insects away.
  2. Closing off nesting sites: Seal cracks and crevices in walls and eaves to prevent bats from roosting.

Installing Physical Barriers

  1. Porch screening: Install screens on windows and doors to prevent bats from entering your porch.
  2. Netting: Attach netting to the underside of porch eaves to block access to roosting spots.
  3. Bat cones: Install bat cones or tubes, which allow bats to exit but not re-enter the roosting area.

Using Lights

  1. Motion-activated lights: Install motion-sensor lights to startle bats and discourage roosting.
  2. Floodlights: Use floodlights to illuminate the porch area, making it less appealing to bats.

Utilizing Sound Deterrents

  1. Ultrasonic devices: Install ultrasonic devices that emit high-frequency sounds to repel bats.
  2. Radio or other noise sources: Play a radio or use other noise-generating devices to create an unwelcoming environment for bats.

Natural Repellents

  1. Essential oils: Use essential oils, such as peppermint or eucalyptus, to create an unpleasant smell that deters bats.
  2. Mothballs: Hang mothballs in a mesh bag near roosting spots, but ensure they are out of reach of children and pets, as they can be toxic.

Installing Bat Houses

Installing a bat house is an effective way to encourage bats to roost away from your porch.

Purpose of Bat Houses

  • Bat houses provide alternative roosting sites for bats, reducing the likelihood that they will choose your porch.
  • By attracting bats to bat houses, you can still enjoy the benefits of having bats around, such as pest control, without the nuisance of them roosting on your porch.

Choosing the Right Location

  • Install the bat house at least 10-15 feet off the ground to protect bats from predators.
  • Choose a location with plenty of sunlight, as bats prefer warm roosting sites.
  • Ensure the bat house is near a water source, as bats need water for drinking and foraging.

Proper Installation and Maintenance

  • Mount the bat house on a pole or the side of a building, avoiding trees that may obstruct the entrance or provide easy access for predators.
  • Ensure the bat house is securely attached to prevent it from falling or swaying in the wind.
  • Clean and inspect the bat house annually, preferably in the fall or winter when bats are not present, to ensure it remains in good condition.

When to Call a Professional

In some cases, you may need to seek professional help to address a larger bat problem.

Signs of a Larger Bat Problem

  • Large numbers of bats roosting on your porch or in your home.
  • Persistent bat droppings and strong odors, which may indicate a large colony.
  • Structural damage caused by bats, such as stained or sagging walls.

Identifying Local Wildlife Control Services

  • Research local wildlife control services that specialize in bat removal.
  • Look for companies with experience in humane bat exclusion techniques.
  • Ensure the company is licensed and adheres to local regulations regarding bat removal.


By understanding bat behavior and employing a combination of prevention and deterrent methods, you can effectively keep bats away from your porch while respecting their important role in the environment. Remember to always use humane methods and consider providing alternative roosting sites, such as bat houses, to encourage these beneficial creatures to live nearby without causing a nuisance. If you suspect a larger bat problem, don’t hesitate to contact a professional wildlife control service for assistance.
