Before you start getting rid of porcupines, you need to know a lot about them. Information about their diet, habits, and preferences will help choose a method to eliminate unwanted guests.

What are porcupines

Porcupine is a big rodent with a very recognizable feature: these animals have sharp needles on their bodies. The animal needs such a peculiar weapon for protection. In case of danger, these rodents shake their numerous needles, emitting a crackling sound, warning, and frightening the predator.

If this does not help, they can rush to attack their abuser. The quills on the porcupine’s body are weak and fragile, but it cannot throw them. When attacking, they get stuck in the enemy, causing severe pain. The needles of this rodent are equipped with a large number of small scales, making the process of removing them rather painful.

New ones replace the lost needles. A porcupine, on average, changes several thousand of the needles during its life. And the total number of needles in the North American porcupine is 30 thousand or more.

Porcupines are mostly active at night. Social flock life is not for this kind of animal. Unlike the other species, the North American porcupines may form flocks, including a mother with its offspring. In the wild, porcupines live for about ten years, in captivity, two times longer.

What do porcupines eat

Before you find out how to get rid of these animals, you have to know about porcupine eating habits. The porcupines` species are vegetarians. They eat exclusively plant foods, including grass, fruits, leaves, bulbs, shoots, and plant rhizomes. Sometimes they also can feast on the tree bark. However, sometimes they can eat bones to sharpen their teeth and to get some minerals.

Porcupines can make nests, but they usually hide for cover. The shelter can become a hollow log, an abandoned rate of another rodent or larger animal, and holes between stones. In your home, they may also take refuge in a basement or shed where there are holes. So it is worth searching for any secluded places.
