Vermin can attack fridges and freezers: Something that is not so common is when insects or rats attack the seals on your fridge or freezer stored in the garage or shed. If the seal is old and not sealing well vermin are able to smell the food inside the fridge and will start to attack the seal in order to get into the fridge. A well fitted new seal and door alignment should stop this problem, as well as cleaning any spills around the face or on the seal to prevent attracting vermin to the fridge.
