In Michigan specific types of non-protected mammals include the: Arctic shrew,
masked shrew, smoky shrew, pygmy shrew, water shrew, short-tailed shrew, eastern mole, star-nosed mole, eastern chipmunk, least chipmunk, white-footed mouse, deer mouse, meadow jumping mouse, woodland jumping mouse, house mouse, southern red-backed vole, meadow vole, woodland vole, southern bog lemming, Norway rat, and porcupine." There are some protected shrews, but I don’t know the difference between them when I find them in the mouse traps in the shop.
Many things in our state are legal to shoot if they are causing or about to cause damage. Anything that makes a mess out of my place and chews into my barn, garage, shed, and digs up the place even pulling all the gravel out from under my driveway...... is going to get it. I don't go out in the woods and hunt them or anything, but if they are within 50 yd. of a building they are fair game. There is also one less unnamed winged critter around my place after it made a mess of every window in the house and crapped all over my deck and grill because it was obsessed with my sliding glass door. I put up with that for two very long weeks. Then one day he was gone. I don’t know if he was protected or not, but I didn’t do anything so it doesn’t matter.
Here is more info on the cute little devils.
Damage and Damage Identification
Throughout their North American range, chipmunks are considered minor agricultural pests. Most conflicts with chipmunks are nuisance problems. When chipmunks are present in large numbers they can cause structural damage by burrowing under patios, stairs, retention walls, or foundations. They may also consume flower bulbs, seeds, or seedlings, as well as bird seed, grass seed, and pet food that is not stored in rodent-proof storage containers. In New England, chipmunks and tree squirrels cause considerable damage to maple sugar tubing systems by gnawing the tubes.
Legal Status
Chipmunks are not protected by federal law, but state and local regulations may apply. Most states allow landowners or tenants to take chipmunks when they are causing or about to cause damage. Some states, (for example, Georgia, North Carolina, and Arkansas) require a permit to kill nongame animals. Other states are currently developing laws to protect all nongame species. Consult your local conservation agency or USDA-APHIS-ADC personnel for the legal status of chipmunks in your state.
