In Arizona, summer marks the peak of bat activity. As temperatures rise, bats become more active, seeking food and shelter. For many homeowners and businesses, this can mean increased chances of bats entering attics, walls, or other parts of the building.

Why Does Bat Activity Peak in Summer?

Summer is prime time for bats because insects—their main food source—are abundant. Bats emerge at dusk to hunt mosquitoes, moths, and other flying insects. Additionally, summer is maternity season for many bat species in Arizona. Female bats gather in colonies to give birth and raise their pups, often inside attics or quiet building spaces.

Common Signs of Bat Presence

• Chirping or squeaking noises in attics during twilight hours
  
• Dark stains or smudges near vents or roof edges
  
• Strong ammonia-like odors from accumulated droppings (guano)
  
• Seeing bats flying around dusk near your home
  

Why You Should Act Quickly

Bats are beneficial for Arizona’s ecosystem, controlling insect populations naturally. However, their presence inside buildings can pose health risks, such as exposure to histoplasmosis and potential rabies. Also, bat droppings can cause structural damage over time.

Humane Bat Management Solutions

If you suspect bats have taken up residence in your home, it’s important to contact wildlife professionals who specialize in humane bat exclusion. Proper exclusion methods prevent bats from re-entering while protecting the bats themselves, which are often protected species under state law.

Preparing for Bat Season

• Inspect your home’s exterior for gaps or cracks where bats can enter.
  
• Seal openings larger than ¼ inch with appropriate materials.
  
• Avoid disturbing bat colonies during maternity season (usually mid-summer).
  
• Schedule professional bat exclusion services early in the season for best results.

DIY Summer Tips

Install Bat Houses Nearby
Encourage bats to roost away from your home by putting up bat houses in your yard. This helps bats control insects without getting inside.

Turn Off Outdoor Lights at Night
Bats avoid bright lights. Reducing outdoor lighting after dusk can discourage bats from hanging around your house.

Keep Windows and Doors Screened
Make sure all windows and doors have tight-fitting screens to block bat entry points.

Remove Standing Water
Eliminate sources of standing water that attract insects, reducing bat feeding spots near your home.

Trim Tree Branches Away From Roof
Bats can use overhanging branches to access your roof or attic. Keep trees trimmed back.

Avoid Handling Bats
Never touch bats yourself—even if you find one grounded. Contact professionals if you find a bat inside.

Seal Small Gaps and Cracks
Check for openings larger than a quarter-inch and seal them with caulk or mesh before the season peaks.
