Squirrel & backyard pest control with airguns
By James · Updated July 24, 2026 · Editorial policy
Field protocol: every load gets a 10-shot chronograph string (average velocity, extreme spread, energy) before it's trusted on game. Holdovers are confirmed at real distances, then re-confirmed in field conditions. Shots are recorded through the scope cam, and claims on this page link to footage where it exists.

Legality first — before gear, before anything
Airgun discharge law is hyper-local: state wildlife codes set species, seasons, and legal methods, and city ordinances frequently ban discharging any projectile inside limits regardless of what the state allows. Ground squirrels, tree squirrels, starlings, and rats sit in different legal buckets depending on where you stand. Ten minutes with your city's municipal code and your state's regs is the cheapest gear on this page.
The energy floor — squirrels punch above their weight
Ask anyone who's hunted both: squirrels soak hits that flatten rabbits. Thick hide, dense muscle, absurd will to reach a tree. The working floor is 9–12 FPE delivered at the animal — treat it as a minimum, not a target — and the placement rule is absolute: head, or pass. Verify what your load actually delivers with the FPE calculator and a chronograph; the caliber guide covers why .22 is the sweet spot here.
The backyard setup: quiet, safe, boring
- Platform: shrouded .22 PCP — no springer clatter, muzzle report like a stapler. The Marauder built its whole reputation on this job.
- Ammo: heavy domed pellets kept subsonic (under ~950 FPS). No sonic crack, and pellets shed energy fast past the target — a genuine safety feature near houses. This is one place my slugs stay in the truck: over-penetration has no place in a backyard.
- Backstop: every shot ends in dirt, a bank, or a proper pellet trap. Never sky, never fence line, never "probably fine."
- Angles: shooting upward at a squirrel on a branch sends misses into the neighborhood. Wait for the ground, or position for a rising backstop.
Field proof — pest control on camera
This is the work the guide describes, filmed through the scope. First, a full pest-control hunt in Mexico with the Impact M4:
And the reason pest control isn't optional on my own ground — the rattlesnake encounter with my dog, and the response:
Bottom line
Legal ground, quiet shrouded .22 PCP, heavy subsonic domes, 9–12+ FPE on target, headshots, hard backstop. Pest control done right is quiet, undramatic, and effective — save the drama for the rattlesnakes.
