The field mice is a name given to any type of mouse that lives in meadows and fields to feed off the crops. They are no different than regular mice other than where they live.

Adult field mice can breed as early as fifty days old. The female can breed year round and once they mate the gestational period is only twenty days. They tend to have litters with between 10-20 pups in them. That is how they reproduce so fast. Not to mention a female can breed again in as early as 2 days after weaning the babies. Which means that one female could possibly have 6-8 litters a year. Yielding approximately 160 babies per year. Now if they are inbred mice the gestational period is shorter, so they can breed more often.
Field mice will eat anything that is not meat. They love to feed on fruits, vegetables and grains. Mice can consume about 3.5 Oz of food per day, which may not seem like much if you only have a few, but within a year you could have 200 or more mice. That could add up to a lot of crops and grains lost for a farmer. Field mice are primarily nocturnal, so you will need to try and see them at night.
Field mice can carry parasites on their bodies and in their feces. Since they will normally defecate shortly after eating, chances are anything they have been into will have feces in it. These parasites have been known to cause some serious illnesses in humans. In the US there has been evidence of field mice carrying the Hantavirus. This virus has been known to cause Hantavirus Pulmonary Syndrome in humans coming in contact with excretions from field mice.
Getting Rid of Field Mice
The best way to get rid of field mice is with traps or poison. Just be careful where you put them so that no one else comes in contact with them.
Prevention of them is the best method. You may not be able to prevent all of them from getting into crops, but there are things you can do to limit them. A good natural enemy to field mice is a cat. You could get a few outside cats to roam around in the fields at night to catch the mice. Traps are also a good idea; just remember where you put them because they will catch other things as well.
Make sure that all openings are covered around your house. You will also want to make sure that there are no openings in barns or sheds where grain or crops are being stored. Using hardware netting can help to cover holes while still allowing venting.
