Professional Bat Control in Castle Rock & the Denver Metro Area
Bats roosting in your attic, garage, or porch? Colorado law protects bats as a beneficial species, making proper removal essential. OMNIS Pest Control specializes in humane, legal bat removal that protects your family while preserving these important creatures. With 13+ years serving Castle Rock and surrounding communities, we know Colorado’s bat species and exactly how to exclude them safely.
Why Bats in Your Home Are a Serious Problem
Popular movies portray bats as symbols of evil and misfortune. While that’s largely unfair to these beneficial creatures, bats inside your home create real problems that demand professional attention. They’re not just a nuisance—they can threaten your family’s health and your property’s value.
Health Risks:
- Rabies exposure – While less than 1% of wild bats carry rabies, they are the leading cause of rabies transmission to humans in the U.S.
- Histoplasmosis – Bat droppings (guano) harbor fungal spores that cause this serious respiratory illness when disturbed
- Parasites – Bat mites, ticks, and fleas can infest your living spaces
Property Damage:
- Guano accumulation damages insulation, wood, and drywall
- Strong ammonia odors permeate living spaces
- Urine stains ceilings and walls
- Entry points compromise your home’s envelope
Pest Threat Level: 5/10
Bats pose moderate risk to homeowners. While they rarely attack humans and most are healthy, the potential for rabies exposure, respiratory illness from guano, and property damage requires professional management. The main threat comes from prolonged infestations where guano accumulates and bats establish permanent colonies.
Low Aggression
Bats avoid humans and rarely bite unless handled. They’re not territorial like wasps or hornets.
Disease Risk
Primary concern is rabies and histoplasmosis from accumulated guano. Proper cleanup is essential after removal.
Protected Species
Colorado law prohibits killing bats. Professional exclusion and humane removal are legally required.
Colorado’s Common Bat Species
Of the 40 bat species in North America, 18 call Colorado home. The three most common species we encounter in Castle Rock, Parker, Monument, and the Denver metro area are:
- Little Brown Bat – Colorado’s most common house-dwelling bat. Small (3-4 inches), brown fur, frequently roosts in attics and wall voids.
- Big Brown Bat – Larger (4-5 inches), often found in garages, barns, and porch overhangs. More cold-tolerant than other species.
- Long-Eared Bat – Distinctive large ears, prefers eaves and covered porches. Less common but present throughout the Front Range.
Each species has different behaviors and roosting preferences, which is why experienced pest control technicians really shine—we have first-hand knowledge of how specific bats behave in Colorado.
Why DIY Bat Removal Fails (And Can Be Dangerous)
Common DIY Mistakes
- Sealing entry points while bats are inside – Traps bats in your home, causing them to seek entry into living spaces
- Using poison or pesticides – Illegal in Colorado and creates a hazardous situation with dead bats decomposing in walls
- Handling bats without protection – Risk of bites, scratches, and disease exposure
- Improper guano cleanup – Disturbing droppings releases histoplasmosis spores into the air
- Timing removal during maternity season – Trapping flightless baby bats inside creates a wildlife emergency
Myths That Get People Hurt
- “Mothballs will drive them out” – Naphthalene repellents are ineffective at safe concentrations and toxic at effective ones
- “Ultrasonic devices work” – No scientific evidence supports ultrasonic bat repellents
- “I’ll just wait for winter” – Big brown bats can hibernate in your attic; the problem doesn’t go away
- “One bat means I have bats” – A single bat may be accidental; colonies are the real concern

The OMNIS Bat Removal Process
Our technicians follow proven methods developed over 13+ years of bat removal in Colorado. Every step is designed to protect you, your property, and the bats themselves.
1. Inspection
We identify the bat species, count the population, locate all entry points, and assess the extent of guano accumulation.
2. Exclusion Plan
We create a customized plan that accounts for the season, species behavior, and your home’s specific vulnerabilities.
3. Humane Removal
We install one-way exclusion devices that let bats exit safely but prevent re-entry. No bats are harmed in the process.
4. Prevention
We seal all entry points permanently and clean affected areas. Optional: Install a bat house to redirect bats away from your home.
Bat Exclusion: The Only Permanent Solution
Exclusion is the most effective and humane method for removing bats from buildings. Rather than trapping or killing bats (which is illegal in Colorado), we focus on sealing them out permanently while allowing any remaining bats to leave safely.
Exclusion Devices We Use
- One-way valves – Allow bats to exit at dusk but prevent re-entry
- Bat netting – Covers larger openings while maintaining airflow
- Chimney caps – Prevent access through chimneys while allowing ventilation
- Vent screens – Metal mesh covers for attic and soffit vents
After bats have vacated, we seal all entry points with professional-grade materials designed to withstand Colorado’s weather extremes.
Safe Guano Cleanup After Bat Removal
Removing bats is only half the job. Accumulated guano poses serious health risks and must be cleaned properly. OMNIS provides complete post-removal sanitation to protect your family.
Why Professional Cleanup Matters
- Histoplasmosis prevention – Disturbing dry guano releases harmful fungal spores; we use proper containment and ventilation
- Complete sanitization – We treat affected areas with antimicrobial solutions that eliminate pathogens
- Odor elimination – Strong ammonia smells from bat urine require enzymatic treatments to fully remove
- Insulation replacement – Heavily contaminated insulation must be removed and replaced
Our Cleanup Process
- Disinfect first – We saturate guano with a hydrogen peroxide and ammonia solution to prevent spore release
- Full PPE – Our technicians wear N95 respirators, goggles, and nitrile gloves
- Careful removal – Guano is bagged and disposed of as biohazard waste
- Surface treatment – All affected surfaces are sanitized and deodorized
- Restoration – Damaged materials are replaced to pre-infestation condition

When to Call for Emergency Bat Removal
Some situations require immediate professional attention:
Signs of Possible Rabies
If you encounter a bat showing these symptoms, do not touch it:
- Fearlessness at the approach of humans
- Frenzied movement during daylight hours
- Poor coordination or inability to fly
- No interest in food or drink
- Paralysis or foaming at the mouth
Call OMNIS immediately if you see these signs. We can safely capture the bat for rabies testing.

Exclusion
- Seal all gaps larger than 3/8 inch
- Install chimney caps
- Screen attic vents
- Repair broken soffit panels
Deterrents
- Install bright lights near roost areas
- Use fans to create airflow
