Hi Tom. Begin by eliminating entry points. Then you can bait mouse traps with either peanut butter or cheese. Placement of the mouse traps is critical. Leave them where you are seeing the mice. Good luck Tom.
Hire a cat, or barrow one from a neighbor, organic pest control.
Rescue an outside cat from your shelter....you'll save a life and make a friend.
Go around the outside of your house and look very objectively for tiny entrance ways, cracks, holes, windows and casements, door leaks, places where wires/pipes enter or exit your house. Remember mice can climb. Seal them up with a spray-in foam that you can buy at a diy store just for this purpose. Also take a look inside to and seal up those spaces too. The foam will actually cut their faces when they try to chew through it. You might consider steel wool as a backup for some spaces that are large.
Now for the inside, the sticky traps have worked best for us. Mice tend to run around the rooms in patterns so place the sticky traps-wide open and flat in these pathways. They learn fast so keep on altering where you place them in the pathways. These are cheap and you can get a good immediate deal on a package of them from Walmart in the pest control section.
They have a very high metabolism and need to feed often, plus have a need to chew, they do not need water.
When we had an infestation of them (5-7), they ignored the conventional baited snap traps & won't eat the bait of the store purchased devices. They played havoc in the pantry, one mess after the next, it was hard to tell what was going to be compromised next. We ended up putting everything in hard covered plastic bins that was not in a metal can. They even chewed the paper on the cans.
In the closets or storage places in the house, go through the pockets and bags, etc...and look for any forgotten food sources like candy, even in dressers because they will go there.
So sorry you have this problem. Best to you.
