Hi,

Had the same problem. Used the Victor clip mouse traps with peanut
butter, they look like Big paper binder clips. The glue ones also work
but can only be used once. The Traditional wire ones are cheap but do
not work that well. Most caught in one night was 3 mouses / mice.

The mice kept on turning up though over the next six months. Tried
desperately to look for a hole could not find one. Noticed most of the
action was in one area of the basement. Eventually found a hole there,
or rather a gap in between the wall and a drain vent pipe. The metal
cover had come loose and the critters could sneak pass.

To seal up the gap used foam sealer. These are available at Home depot
for about $US 7 per can. One can has more than enough. Try and make
sure you find all your holes because once started the can is good for
about 20 minutes. What happens is the foam starts to set in the
plastic feed tube if you do not keep on spraying. So you got to use it
up and fill all your holes in one shot.

So far so good ... fingers crossed .....

Best, Mike.
