How to Get Rid of Bats: The Ultimate DIY Guide That Really Works!

If you’re shooting lasers through your attic—or hearing mysterious, high-pitched squeaks at night—chances are you’ve got bats on your hands. While these little night flyers are essential to ecosystems, they’re not welcome guests in attics, sheds, or barns. Not only can bats damage your property with droppings and urine, but some species carry serious diseases like rabies and histoplasmosis. The good news? You don’t need a wildlife expert to eliminate bats—this ultimate DIY guide reveals proven, safe, and effective ways to get rid of bats the right way.


Understanding the Context

Why Bats Invade Homes (And Why DIY Can Work)

Bats seek shelter in quiet, dark spaces—precisely the areas where humans sometimes unwittingly create inviting habitats. Cracks, gaps, and unmaintained roofline features can turn your home into a cozy bat hotel. Unlike rodents, bats can’t chew through wood easily, but they’re opportunistic explorers. Once inside, they settle in and require professional removal due to zoonotic risks.

Why DIY Works:
Professional bat removal often involves specialized tools, permits, and safety gear—not to mention local regulations protecting bats. A well-executed DIY approach reduces risks, costs, and stress. With the right steps, you can safely and humanely exclude bats without harming them or your property.


Key Insights

Step-by-Step: How to Get Rid of Bats Effectively

1. Confirm Bat Presence (Don’t Guess!)

Look for:

  • Earliest morning or latest evening droppings (guano)
  • Foul, musky odor
  • Scratching or squeaking sounds in the attic
  • Grease marks or oil smears near entry points

Use a flashlight at dusk to spot roosting colonies, but always wear gloves and a mask—bat waste contains deadly fungi.

2. Seal Entry Points (The Key to Prevention)

Bats enter through gaps under ¼ inch—so focus on sealing small cracks, broken screens, and loose fascia boards. Use:

  • Steel wool plugged with steel putty
  • Caulk with bird/rodent-resistant formulas
  • Window and chimney caps

Important: Never seal bats inside—this traps them and violates wildlife laws. Always secure them outside.

Final Thoughts

3. Install Bat Exclusion Devices

These one-way doors let bats fly out but prevent reinfestation. Install them at your most likely entry points during daylight hours when bats are dormant. Wait at least 3–5 days to ensure all individuals have left.

4. Clean and Sanitize Safely

If bats have already moved in:

  • Wear full PPE: HEPA-rated mask, gloves, goggles
  • Moisten droppings with diluted bleach (1 part bleach to 10 parts water)
  • Scrub affected areas, then dispose of contaminated materials in sealed bags
  • Ventilate the space afterward—unventilated areas trap dangerous spores

5. Deter Bats with Non-Lethal Scare Tactics

While bats won’t stay, they return if conditions are right. Try:

  • Reflective tape or CD reflectors (movement deters nervous flyers)
  • Wind chimes or ultrasonic devices (some disrupt bat sonar)
  • Decoys like plastic owls or fake snakes (rotate them weekly)

6. Call Professionals When Needed

Complex cases—large colonies, nesting in hard-to-reach areas, or repeated infestations—benefit from expert help. Wildlife removal specialists ensure humane, legal, and thorough bat eviction, reducing disease risks.


When to Call a Professional

  • Bats occupy chimneys, vents, or protected wildlife areas
  • Entry points are inaccessible or extensive
  • You suspect rabies exposure or severe infestation
  • Local laws require licensed intervention

Prevention: Keep Bats Out Before They Enter

  • Seal gaps and holes year-round
  • Install bat-proof screens on vents
  • Trim trees near eaves to eliminate landing sites
  • Maintain attics with regular inspections
