Myth: Mice love cheese and it makes a great bait for mouse traps.

In fact, as any pest exterminator or pet shop owner knows, mice don't really like cheese at all and they'll even actively shy away from certain types of cheese (they have a very sensitive sense of smell and certain cheeses give off odors that are repulsive to many types of mice).

According to Dr. David Holmes of Manchester Metropolitan University who recently did a study on whether mice liked cheese or not, while if hungry enough, mice will pretty much eat anything (even nibble on you, cardboard, whatever), most type of mice strongly prefer grains, fruits, and sweet things; certain types of mice will also eat insects and other small animals. Basically, they like to eat what they've been accustomed to eating since before humans started making cheese around 10,000 years ago.

So if cheese isn't an effective bait for mouse traps, what is? Turns out, mice go crazy for peanut butter (aside: peanuts are not actually nuts). They also like chocolate (the sweeter the better).
