Did You Know?
A single bat can eat up to 1,000 mosquitoes per hour — one of nature's most effective pest controllers.
Woodpeckers drum up to 20 times per second. Special shock-absorbing skull structures protect their brains.
Bats pollinate over 500 plant species worldwide, including bananas, mangoes, and agave.
Pigeons can navigate home from over 1,000 miles away using Earth's magnetic field, the sun, and road landmarks.
Bats use echolocation so precise they can detect a human hair in total darkness. Some calls exceed 140 decibels — louder than a jet engine.
Starlings form flocks of over a million birds in mesmerizing aerial patterns. Each bird tracks just seven neighbors, yet the flock moves as one.
What You Can Do
Inspect rooflines, eaves, and vents for gaps. Cover openings with hardware cloth or mesh to block nesting access.
After birds leave for the season, remove old nests from ledges and eaves to discourage return visits.
Reflective tape, predator decoys, and motion-activated lights deter birds from roosting on your property.
Keep trash sealed, clean up pet food, and use bird feeder baffles to feed songbirds without attracting pests.
Droppings are acidic and corrode paint, metal, and masonry. Clean roosting areas regularly with gloves and a mask.
A bat house on a nearby tree gives bats an alternative roost after exclusion — keeping them around to eat mosquitoes without living in your attic.
What to Avoid
Many species are protected by the Migratory Bird Treaty Act. Removing active nests with eggs or chicks can result in federal fines.
Bats are protected in California. Trapping, poisoning, or harming them is illegal. Use humane exclusion during the proper season.
Sealing holes with bats or birds still inside traps them in your walls — causing odor and health hazards.
Droppings can carry histoplasmosis and other pathogens. Always wear gloves, a mask, and dampen droppings before cleaning.

No-Kill Methods
Prepare for Your Appointment
Observe where birds or bats enter and exit your home. This helps your technician plan the exclusion strategy.
Record when you see the most activity — dawn, dusk, or overnight. This tells your technician when animals are coming and going.
Ensure your technician can easily reach the attic, crawl space, or storage areas where nesting may be occurring.
Take photos of droppings, nesting material, or damage. This helps your technician assess the situation before arrival.
Don't seal holes yourself — animals may get trapped inside, causing odor and health problems. Let your technician handle exclusion.
Keep children and pets away from contaminated areas until your technician can assess and address the situation.
Your technician will guide you on arrival.
