Deciding between DIY bat exclusion and hiring a professional depends on colony size, roof complexity, and your comfort level with heights. Both approaches can be effective, but they have different costs, timelines, and success rates.
This guide compares DIY bat exclusion with professional removal side by side, so you can make an informed decision based on your specific situation.
Key Takeaways
- DIY cost: DIY bat exclusion costs $200-$600 for materials (exclusion valves, hardware cloth, caulk, chimney cap, PPE).
- Professional cost: Professional removal costs $500-$2,500 depending on colony size, home complexity, and cleanup needs.
- When DIY works: Small colonies (under 20 bats), simple rooflines, and easy attic access are good DIY candidates.
- When to hire a pro: Large colonies (50+ bats), complex rooflines, wall roosts, and inaccessible attics require professional help.
- Hidden costs: DIY mistakes can cost more than professional work. Sealing bats inside, missing entry points, or falling from a roof are expensive errors.

When DIY Bat Exclusion Makes Sense
DIY bat exclusion can be successful and cost-effective in these situations:
- Colony size under 20 bats (small, manageable colony)
- Simple, single-story roofline with easy access
- Entry points are clearly visible and accessible
- You are comfortable working on a ladder at roof height
- You have the time to perform the work over 1-2 weeks
- Guano accumulation is minimal (under 2 inches deep)
- The bats are in the attic, not in walls or chimney

When to Hire a Professional
Professional bat removal is strongly recommended in these situations:
- Colony size of 50+ bats (large colony)
- Complex multi-story roofline with multiple valleys
- Bats are in wall cavities or other hard-to-access areas
- The roofline is steep or dangerous to access
- You have a large accumulation of guano (2+ inches deep)
- The bats have been present for more than one year
- You are unsure about the bat species or legal status
- Previous DIY attempts have failed
- You are physically unable to work at heights
Pro Tip
When hiring a professional, ask about their exclusion methods, warranty, and whether they subcontract the work. A reputable company will use one-way exclusion valves, seal all entry points, and provide a written warranty.
Avoid companies that offer to \”remove\” bats with traps or poisons , these are illegal for bats.
How to Choose a Bat Exclusion Professional
Not all wildlife removal companies are equally qualified for bat exclusion. Here is what to look for:
- Licensed by the state wildlife agency (required for bat work in most states)
- Member of the National Wildlife Control Operators Association (NWCOA)
- Specializes in bat exclusion (not general pest control)
- Uses one-way exclusion valves, not traps or poisons
- Provides a written warranty (typically 1-5 years)
- Has positive reviews and references specifically for bat work
- Carries liability insurance and worker’s compensation

Frequently Asked Questions
Does homeowners insurance cover bat removal?
Most homeowner’s insurance policies exclude bat removal and damage. However, some policies cover structural damage caused by bats. Check your policy and ask your agent.
How long does professional bat removal take?
Most professional jobs take 1-3 days for installation, followed by a 5-7 day exclusion period. A final visit is needed to remove valves and seal remaining openings.
Can I negotiate with a bat removal company?
Yes. Get multiple quotes (3-5 is standard). Some companies offer discounts for off-season work (fall and winter). Bundle inspection and exclusion for a better price.
What happens if the bats come back?
A reputable company provides a warranty. If bats re-enter within the warranty period, they return at no cost. This is the main benefit of professional work.
