Wildlife removal: squirrels, raccoons, bats, and what humane really means

Wildlife in your attic, walls, or crawlspace isn't an extermination problem — it's a removal-plus-exclusion problem with a legal layer. Squirrels and raccoons damage insulation; bats and birds can carry diseases; all of them require species-specific approaches and often permits.

Squirrels: $300–$700

Most common attic invader. Pros set live traps or one-way exclusion doors at entry points. Babies in spring/fall require waiting until they're old enough to leave on their own (humane standard). Total project typically includes trap, removal, and exclusion sealing.

Raccoons: $500–$1,200

Larger, more destructive, and frequently rabies vectors. Live trapping plus exclusion is standard. Most states require licensed nuisance wildlife operators. Mother raccoons with babies in attics require careful timing — never seal a mom out before babies can travel.

Bats: $400–$1,500

Exclusion-only (live trapping is generally illegal and harmful). Pros install one-way exclusion devices, wait for the colony to leave, then seal entry points. Cannot be done June-August in most states due to flightless pups. Guano decontamination ($200–$800 extra) is often necessary.

Birds: $200–$800

Sparrows, starlings, and pigeons. Exclusion uses netting, spikes, and gel deterrents. Federally protected species (most native songbirds) cannot be killed; only the non-native invasive species can be controlled aggressively.

The exclusion + repair step

Wildlife removal without exclusion is a failure. Pros seal entry points with hardware cloth, sheet metal, or appropriate construction materials. Insulation damaged by wildlife frequently needs replacement ($1,000–$5,000 depending on extent) — and this is often a separate line item.
