I am not going to try to take apart the dishwasher. Call me chicken.

Thanks for the suggestions. I will let you know as the battle progresses. If I suddenly stop posting you'll know the roaches won.

We have 2 cats, one is a great mouser although she prefers baby bunnies, of which there are plenty. She's getting older and doesn't see or hear as well, but she can still catch a baby bunny. She is very generous, and often leaves half the bunny for us. On our doorstep. Always with the stomach prominantly displayed.

And yet a few years ago we did have a mouse problem, in the attic. Of course, we don't let her go in the attic, no matter how she pleads. We put out traps and poison and the mice disappeared eventually. Now that the field across the street is being developed, we will have fewer mice, and baby bunnies, and deer. Instead we will have college students. Of all vermin, college student infestations are the worst.
