The best way to control problem birds is by?

• A. Trapping
• B. Exclusion
• C. Shooting
• D. Avitrol

Answer: (B)

Blocking access to a structure is the most effective way to handle problem birds because it stops them from entering, roosting, and nesting in the first place. Exclusion works by sealing gaps, installing chimney caps, vent covers, door sweeps, and other barriers, plus using netting or bird-proofing materials on open areas. When birds can’t find suitable shelter or nesting sites, the infestation drops dramatically and doesn’t rebound as quickly as with reactive methods.

Trapping tends to remove birds temporarily and can be impractical for whole-building problems. Shooting is usually unsafe, often illegal, and doesn’t address how birds are getting in. Avitrol is a restricted chemical method that carries safety and non-target risks and isn’t a preferred long-term solution. So the most reliable, humane, and sustainable approach is to exclude birds from the structure.
