5. Most mice feed on fruits, seeds, grains, and occasionally meat.
6. They produce 5–10 litters a year with up to 14 mice in each litter.

Are Rats And Mice Dangerous?

Rats and mice alike can exhibit similar behaviors inside your property if they have infested your home. They are also both dangerous in several ways. Rodents are infamous for their ability to carry and spread a number of potentially dangerous diseases. They also can trigger allergies in people. A rodent problem can be a mess to clean up due to the amount of droppings and urine left behind. Lastly, they can cause significant damage to your home. Both mice and rats will chew through insulation, cardboard, wood, and electrical wiring. Needless to say, this can be rather dangerous.
