Xylitol doesn't kill mice, wish it did! I have a mouse in the kitchen that got into a drawer & ate at least 2 pieces of gum & I'd hope it would kill said mouse but it didn't. 2 days ago this mouse jump started my heart as I was fixing breakfast for my boys & as I reached to turn on the water this nasty creature came running at my hand causing me to jump & almost fall. I've got 4 traps but haven't caught it yet. Mice belong outside where the owl can catch them not in my kitchen.
