Just moved to the states, inherited a boomer’s mountaintop villa, they treated it like shit so I got rats.
Traps, RatX, poison, fucking electric shock traps, patching holes but they keep chewing through the fucking drywall, throwing everything I can at the fuckers, but there are some holdouts, sometimes I walk into the kitchen and see a lone rat on the windowsill, and there are still quite a few in my garage.

Need something to plink the cunts with, was thinking a BB pistol I can carry while indoors, I would get a rifle if necessary, but would prefer a pistol.
Wondering what I can get, with the highest muzzle energy possible?
Renovating the house, so I don’t care how deep shit embeds in my drywall, I want these fuckers to drop when I hit them.
What would my /k/ommandos recommend? Are CO2 guns strong enough? i’ve only ever used real firearms before, so not familiar with what I’m dealing with here
