This is a little series I am starting today – I will post advice about how to evict critters from your kitchen without using chemicals 
Mice
Mice do not like peppermint. If you a few sprigs of fresh peppermint between your cabinets, and also where you suspect them to enter your kitchen, they will be deterred. You can also make a solution of 2 cups of water and 3 tsp of peppermint essential oil, and spray wherever you find mouse droppings.
Hint: Mice usually stay close to walls, so that’s where you need to look for the droppings.
