Mouse infestation at my new house and bb guns

A bucket style trap like Glem.Chally suggests can work great.

A bank of snap traps in a wood case can also be very effective but requires a bit more effort to set up correctly.

But my personal favourite:

All three of these solutions have the advantage that you get to keep the corpses. So you don't have to worry about decomposing mice elsewhere in your house. Of course, if you have baby mice hidden away, they'll die without their parents and also cause a stink. 



It seems like an exercise in futility to be shooting a pellet gun at mice in the house. A Crosman P1322 at 1 pump isn't enough to penetrate my own skin. I'd go for at least 3 pumps. That said, clear everything breakable out of the room and cover your windows. 
 
Hey, John, congratulations on your new place! Finally made it happen and got away from that crazy hectic Bay Area! 


you’re in heaven now, but it’s unfortunate about the critters. If it were me I’d be using the traps described by delooper and others, and on top of that I’d have glue traps all over, baited. In time after you go around and patch up any and all questionable access points for these mice, you’ll have won the war and lovin’ your place even more.

if your allergic to cats consider a female German Shepherd as they are all about hunting and killing pests. My female shepherd will jump up as high as she can to nab at a lizard on a tree, and is ruthless on squirrels. She won’t lay idle, always on the prowl she is. Very loyal, also 
 
Here she is, after killing a mouse today-

and here she hides, waiting to snipe on a rat that ran into a hole at the base of the tree to my right behind the storage box-

Dogs (even German Shepherds) have to be taught to hunt. The rare dog just has it in them, but most of the dogs on our farm, if they did not see other farm dogs hunting mice, they'd probably pay little attention to them. 

That said, once a dog learns the fun of hunting mice, they'll love it and always be looking for the little critters. My dog comes back to the house with big fat rats in her mouth. She's so proud of herself. 


 
Definitely getting a dog soon. I had a lab who instinctively killed mice rats and squirrels. I watch a YouTube channel called Joseph Carter mink man. He kills hundreds of mice and rats by picking up bails of hay and pallets and letting his mink in there. Then he has 2 or 3 dogs that murder the ones that run away. It's pretty epic. Thanks for all the ideas.
