In my experience, cats are the most humane and efficient way to control unwanted critters in the property. You may get rid of mice the quick way, but they come back. Cats tend to deter future invasions.Originally Posted by Jetter
What you can do is buy one of those electrical boxes that trap mice and kills it. Its like a foot long and it takes batteries. Inside the box there is an exposed wire that hangs down so when the mouse goes in, it electricutes it. Apparently the batteries are powerful enough to do the job. We have used them at a rental house we have and it is truly the only thing that really works. You'd have to put dog food (or cat food) just at the inside of the box to attract the mouse. Of course, you'd wanna block off the area so you're cat will be alright. Another option is that you can block off the hole by the washer and then go outside and try to find where it go in at and load that area with DECON. It will reeeeeeek but it'll do the trick.
