Watch a woodpecker drill into a home — this is why early deterrents matter.
Prepare for Your Appointment
1
Note Entry & Exit Points
Observe where birds or bats enter and exit your home. This helps your technician plan the exclusion strategy.
2
Document Peak Activity Times
Record when you see the most activity — dawn, dusk, or overnight. This tells your technician when animals are coming and going.
3
Clear Attic & Storage Access
Ensure your technician can easily reach the attic, crawl space, or storage areas where nesting may be occurring.
4
Photograph Droppings & Nesting
Take photos of droppings, nesting material, or damage. This helps your technician assess the situation before arrival.
5
Don't Block Entry Points
Don't seal holes yourself — animals may get trapped inside, causing odor and health problems. Let your technician handle exclusion.
6
Keep Children & Pets Away
Keep children and pets away from contaminated areas until your technician can assess and address the situation.
Your technician will guide you on arrival.
🔍 Did You Know?
Signs of Bird or Bat Activity
Watch for droppings accumulating on ledges, windowsills, or around your roofline. Scratching or squeaking sounds in the attic at dusk signal bats, while nesting materials in vents, gutters, or eaves indicate birds have moved in.
What Attracts Them to Your Property
Birds and bats seek sheltered roosting spots like eaves, attics, and chimneys. Unsealed vents and gaps in the roofline provide easy access. Nearby food sources such as open trash, pet food, fruit trees, and standing water make your property even more appealing.
Health & Property Risks
Bird and bat droppings are acidic and corrode paint, metal, and masonry. Accumulated guano can harbor histoplasmosis spores, a serious respiratory concern. Nests block ventilation, create fire hazards, and attract secondary pests like mites and beetles.
When to Call a Pro
Contact a professional if you have bats in your living space, a large colony in the attic, or birds nesting in vents or chimneys. Many species are legally protected, and improper removal can result in fines or harm to the animals. Humane exclusion requires proper timing and technique.
Seasonal Patterns
Birds nest most actively in spring and early summer. Bat maternity season runs from about May through August, when exclusion should be avoided to protect flightless pups. Fall and winter are ideal times for sealing entry points before the next breeding cycle begins.
Prevention Tips
Seal gaps along rooflines, eaves, and vents with hardware cloth or mesh. Install vent covers and chimney caps. Remove old nests after the season ends, keep trash secured, and trim tree branches that overhang your roof to reduce roosting opportunities.
✅ What You Can Do
Seal Entry Points
Inspect rooflines, eaves, and vents for gaps. Cover openings with hardware cloth or mesh to block nesting access.
Remove Old Nests
After birds leave for the season, remove old nests from ledges and eaves to discourage return visits.
Use Visual Deterrents
Reflective tape, predator decoys, and motion-activated lights deter birds from roosting on your property.
Secure Food Sources
Keep trash sealed, clean up pet food, and use bird feeder baffles to feed songbirds without attracting pests.
Clean Droppings Promptly
Droppings are acidic and corrode paint, metal, and masonry. Clean roosting areas regularly with gloves and a mask.
Install Bat Houses Nearby
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
Don't Disturb Active Nests
Many species are protected by the Migratory Bird Treaty Act. Removing active nests with eggs or chicks can result in federal fines.
Don't Trap or Harm Bats
Bats are protected in California. Trapping, poisoning, or harming them is illegal. Use humane exclusion during the proper season.
Don't Seal While Animals Are Inside
Sealing holes with bats or birds still inside traps them in your walls — causing odor and health hazards.
Don't Clean Without Protection
Droppings can carry histoplasmosis and other pathogens. Always wear gloves, a mask, and dampen droppings before cleaning.
