Oh honey, I know how you feel. I left for a 6 day trip and came home to my kitchen drawers, cupboards filled with mouse dung. My beloved husband said "I've trapped them all and taken care of the mice. I thought I'd leave the kitchen so you could see it."
"Seeeeee it?" How bout cleaning it! It took me a couple days to strip everything out & bleach it all down. And I still saw two more mice under the kitchen sink! The upside was that when we figured out how they were getting in, (through a hole in the wall behind the old dishwasher), I ended up with a brand new dishwasher and a nice clean kitchen! Good things can come in small unexpected packages. I thank the mice for the new dishwasher

We use snap traps because they are the quickest. I put several plastic bags on my hand before picking them up, then turn the bag inside out around them & tie it shut quickly. I would never ever use sticky traps, I've seen mice caught in them and that mouse goes through a living hell before it dies. And poison sounds like an awful way to go to me.

It is sad, but sometimes it must be done. You are not a bad person because of it. Just imagine if rodents overran the world....yuck! (Remember the Black Death?)
