Porcupines do not hibernate. They will either build a nest or find a hollow log, an abandoned burrow, or a stump to protect them from severe weather. And, even though porcupines are mostly solitary, it is common to find several porcupines denning together to stay warm in winter.

Porcupines in Winter

Porcupines are predominantly nocturnal, but during winter when food is more scarce, they will forage both day and night, insulated by their quills and dense guard hairs. During winter, its foraging territory changes, and porcupines stay much closer to their dens than in spring and summer when they can more easily travel for longer distances. Their foraging territory can shrink up to as much as 80-90 percent in winter as they need to save energy, so they retain stored fat through these leaner months. In winter when leaves are scarcer, porcupines will eat the bark of trees, waiting eagerly for spring when they can replenish their fat with new spring growth.

Porcupines live for roughly 10 to 12 years, during which they will use the same den each winter. They place their droppings right at the entrance of their den to deter other animals from moving in.
 

When Porcupines Become a Problem

porcupine basements or crawlspace Portland ME

Porcupines venture into residential areas for a surprising reason—they crave salt that they cannot get from their diet of leaves and bark, and there is plenty of it near humans. Some of their favorite sources of salt include car tires that have driven through salted streets, tool handles and boat oars found in sheds, horse saddles, and plywood that is glued with a sodium-based material.

Porcupines are an uncommon home intruder. If one is a regular in your yard, it is likely because of unusual circumstances such as a drought or food shortage. But, even outside your home, they can cause considerable alarm:

  • They can destroy your trees by stripping them of too much bark.
  • They will help themselves to your vegetable garden.
  • They can damage porches, sheds, car tires, and the wooden handles of tools with traces of human sweat in their search for salt.
  • They pose a health risk to pets, who can fall victim to the porcupine’s quills.
  • Its presence can attract porcupine predators such as fishers.

Ridding Your Property of a Porcupine

Porcupines make strange noises. If you hear strange animal noises, notice that one or more trees are being stripped of their bark, or see small branches and feces around the base of a tree, you might have a porcupine living in your yard. Do not attempt to rid your home of a porcupine on your own.

Porcupine quills are barbed. They are not only painful, but they will also slowly work their way further into a person’s or pet’s skin unless they are removed in a timely way. Critter Control is a full-service wildlife specialist company protecting people, property, and wildlife. We know how to get rid of porcupines in a humane manner and can help you create a landscape that is no longer attractive to these creatures.

Sam did a ton of work on our house when we bought it as a preventative measure against any pests, as the house was not new. We wanted to be sure no mice, bats or other pests could get in. He did all our critter control at our prior house in 2022 so we had him pest proof our next house in 2026. He is the kindest man, knowledgeable and efficient. 100% recommend. You’re buying pest control and peace of mind.

I was concerned that there might be squirrels in my attic. Alex did a complete and thorough inspection of the residential premises, and I am happy to report that he found no such evidence. Alex’s service was very thorough and professional, as well as honest. I would not hesitate to recommend your services to others.

We interviewed 3 companies to evict the squirrels from our attic. Critter Control was, by far, the least expensive. Their promptness and attention to detail was A+. Brandon from Critter Control provided daily reports about the process. Brandon was the star of the show but we enjoyed working with everyone from Critter Control. Thanks Don and Julie

Josh was awesome! We had a critter stuck in our fireplace, and he took his time figuring out the best way to handle the situation. He was creative with his solutions, explained what he was going to do, and made sure we understood the process. He was also just a genuinely great person to work with! As a new homeowner, it was nice to have someone who was patient, knowledgeable, and willing to take the time to get the job done right. He never made us feel rushed, and you could tell he really cared about helping us. Critter Control, you have a great employee in Josh! I hope he gets the recognition he deserves because he did an amazing job. I would absolutely recommend Critter Control, and if we ever have another issue, I will definitely be asking for Josh again!
