Lucy, you always have the best ideas.
Awww Snoopy, that's so sweet. Lildago is a wonderful poster and trust me, we've all been on the receiving end of needing support in any number of areas. You'll be helping someone else soon enough.
My problem with D-con is they still die somewhere in your home; hence there's still a smell to deal with.
When we first moved into our house years ago, it was newly built. Somehow a family of mice ended up between the wall of our bathroom and closet. Particularly in the middle of the night, there would be this scratching in the wall. We were desperately trying to figure out how to get out whatever it was, when Mr. Rose finally hit on a brilliant idea. He stapled a large baggie to the wall where the noise was, then cut a little door in the wall, and sure enough, two mice popped out into the baggie. It was creepy yet wonderful to know they were out and we were rodent-free.
