I had a serious mice issue too. I got metal live traps. They hold about 10 each. To kill them we just drop the live trap in a water bucket and they drown, dispose the bodies in the trash or bury them. At first we started catching 20 a day now it's one or two
. I also cleaned up the house, sealed any open foods, and looked for mouse holes to plug.
Btw dont get the plastic one get the metal even though theu cost a little more. The plastic one, i caught three mice and they chewed their way out.
Hope this helps!
