Keeping porcupines out of your home and garden area requires a combination of several control methods. Keep in mind that some porcupine population control methods, such as trapping and shooting, are not legal in all areas, so be sure to check with your local wildlife agency before enacting a plan.
- Fence the area
Orchards, vegetable gardens and small trees should be surrounded by sturdy fences to keep porcupines away from them. Because porcupines can climb, a single electric wire placed over an 18-inch high wire fence may be effective in keeping them out. A plain wire strip around the top of the fence at a 65-degree angle to the upright wire may also work.
- Place traps
Always check with local fish and wildlife authorities before setting traps for porcupines to ensure that you remain within legal guidelines. These agencies are able to advise you on trap sizes and types that are allowed in your specific area. Keep in mind that catch-and-release traps are not the most effective means of controlling porcupine populations.
- Use a gun
If shooting porcupines is legal where you live, you may be able to keep porcupine populations down by using a 22-caliber pistol or shotgun as easily as trapping the beasts.
