Skunks are common North American mammals recognized for their distinctive black and white coloration and potent defensive spray. Though often maligned due to their odor, these creatures play a role in local ecosystems by controlling insect and rodent populations. Understanding their behaviors, particularly their feeding schedule and defense mechanisms, can help homeowners coexist peacefully with these solitary animals.
Nocturnal Activity: When Skunks Are Most Active
Skunks are primarily nocturnal, meaning they conduct most of their foraging activities under the cover of darkness. They typically emerge from their dens shortly after sunset, making the twilight hours a period of heightened activity. This habit helps them avoid many natural predators, such as coyotes and bobcats. Peak foraging usually occurs in the late evening and continues until just before dawn, when they return to their burrows or sheltered resting spots.
While nighttime activity is the norm, skunks are sometimes seen during the day. Exceptions include nursing mothers needing extra food, juveniles learning to forage, or individuals forced to hunt due to scarce food sources. During the winter, skunks enter a state of torpor and will emerge on warmer nights, especially when temperatures rise above 30°F, to search for food.
The Omnivorous Menu: What Skunks Eat
Skunks are classified as opportunistic omnivores. Their natural diet primarily consists of animal matter during the warmer months, as they favor insects such as grubs, larvae, grasshoppers, and beetles. They locate these by scent and dig them up, often leaving small, cone-shaped holes in lawns.
Plant materials like berries, roots, and nuts become more significant components of their diet during the fall and winter when insects are less abundant. In residential areas, skunks are frequently drawn to human-provided food sources. These accessible attractants include unsecured garbage, compost piles, and pet food left outdoors overnight.
Understanding the Skunk’s Defense Mechanism
The skunk’s defense mechanism is an oily liquid stored in two glands located near the anus. This yellowish musk is composed of sulfur-based organic compounds called thiols, which create a strong, rotten-egg-like odor. Skunks can accurately aim this spray up to 10 to 15 feet away using specialized protrusions.
Spraying is generally a last resort because it can take up to 10 days to fully replenish the supply, leaving the skunk vulnerable to predators. Before deploying the spray, the skunk gives clear warnings to encourage a threat to retreat. These signals include hissing, stomping its front feet, and raising its tail.
Tomato juice is ineffective at neutralizing the odor and only masks it temporarily. The most effective method for immediate odor removal is a mixture that oxidizes the thiols into scentless compounds. A solution of one quart of 3% hydrogen peroxide, one-quarter cup of baking soda, and one to two teaspoons of liquid dish soap is recommended.
Practical Steps for Minimizing Yard Encounters
Reducing the presence of skunks in a yard centers on eliminating the food and shelter that attract them. Homeowners should secure all outdoor garbage cans with tight-fitting lids or bungee cords and avoid placing trash out until the morning of collection. Since skunks are drawn to easy meals, all pet food should be brought inside before dusk.
Addressing potential den sites is another effective deterrent. This involves sealing off access to areas beneath porches, sheds, and decks with galvanized wire mesh. To prevent startling a skunk during its active hours, motion-activated lighting can be installed. This sudden burst of light causes the animal to move away from the area.
