Damage and Damage Identification

Skunks become a nuisance when their burrowing and feeding habits conflict with humans. They may burrow under porches or buildings by entering foundation openings. Garbage or refuse left outdoors may be disturbed by skunks. Skunks may damage beehives by attempting to feed on bees. Occasionally, they feed on corn, eating only the lower ears. If the cornstalk is knocked over, however, raccoons are more likely the cause of damage. Damage to the upper ears of corn is indicative of birds, deer, or squirrels. Skunks dig holes in lawns, golf courses, and gardens to search for insect grubs found in the soil. Digging normally appears as small, 3- to 4-inch (7- to 10-cm) cone-shaped holes or patches of upturned earth. Several other animals, including domestic dogs, also dig in lawns.

Skunks occasionally kill poultry and eat eggs. They normally do not climb fences to get to poultry. By contrast, rats, weasels, mink, and raccoons regularly climb fences. If skunks gain access, they will normally feed on the eggs and occasionally kill one or two fowl. Eggs usually are opened on one end with the edges crushed inward. Weasels, mink, dogs and raccoons usually kill several chickens or ducks at a time. Dogs will often severely mutilate poultry. Tracks may be used to identify the animal causing damage. Both the hind and forefeet of skunks have five toes. In some cases, the fifth toe may not be obvious. Claw marks are usually visible, but the heels of the forefeet normally are not. The hind feet tracks are approximately 2 1/2 inches long (6.3 cm) (Fig. 3). Skunk droppings can often be identified by the undigested insect parts they contain. Droppings are 1/4- to 1/2-inch (6 to 13 mm) in diameter and 1 to 2 inches (2.5 to 5 cm) long.

Odor is not always a reliable indicator of the presence or absence of skunks. Sometimes dogs, cats, or other animals that have been sprayed by skunks move under houses and make owners mistakenly think skunks are present.

Rabies may be carried by skunks on occasion. Skunks are the primary carriers of rabies in the Midwest. When rabies outbreaks occur, the ease with which rabid animals can be contacted increases. Therefore, rabid skunks are prime vectors for the spread of the virus. Avoid overly aggressive skunks that approach without hesitation. Any skunk showing abnormal behavior, such as daytime activity, may be rabid and should be treated with caution. Report suspicious behavior to local animal control authorities.

Legal Status

Striped skunks are not protected by law in most states, but the spotted skunk is fully protected in some. Legal status and licensing requirements vary. Check with state wildlife officials before removing any skunks.

Economics of Damage and Control

Skunks should not be needlessly destroyed. They are highly beneficial to farmers, gardeners, and landowners because they feed on large numbers of agricultural and garden pests. They prey on field mice and rats, both of which may girdle trees or cause health problems. Occasionally they eat moles, which cause damage to lawns, or insects such as white grubs, cutworms, potato beetle grubs, and other species that damage lawns, crops, or hay.

Skunks occasionally feed on ground-nesting birds, but their impact is usually minimal due to the large abundance of alternative foods. Skunks also feed on the eggs of upland game birds and waterfowl. In waterfowl production areas, nest destruction by egg-seeking predators such as skunks can significantly reduce reproduction. The occasional problems caused by the presence of skunks are generally out-weighed by their beneficial habits. Some people even allow skunks to den under abandoned buildings or wood-piles. Unless skunks become really bothersome, they should be left alone. An economic evaluation of the feeding habits of skunks shows that only 5% of the diet is made up of items that are economically valuable to people.

The hide of the skunk is tough, durable, and able to withstand rough use. Generally there is little market for skunk pelts but when other furbearer prices are high, skunks are worth pelting.
