A mouse problem
Some vermin are indeed smart. They can learn to avoid traps. Try moving the location of the traps on a daily basis. Keep them close to the walls. Look for entry locations, remember a mouse can squeeze under holes that would require you or I to lose weight. The best bait I've found for mice is hard salami in a snap trap. They seem not able to resist it.
Good Luck and a Happy and miceless NewYear,
Mice kept on running in and out of my garage but i use the elecrtic mice replelleres.
There are unltasonic ones selling for about $18 CND (these work for about 1 month)then there is a better one called "pest offense" this works all of the time and it is great.It also works on some other rodant pests. GOTO www.pestoffence.com
When I moved into my house, let the cats downstairs about once per week. First couple of weeks, two dead mice. Still let them down once in awhile, not a mouse to be found.
