How to keep squirrels out of my house and other buildings

Squirrels normally build nests of leaves or live in hollow trees, but they will nest in manmade structures if they find access. Here are some ways to decrease the likelihood that squirrels will invade your home:

  • Trim branches and trees six to eight feet away from buildings to minimize the likelihood of squirrels jumping from nearby trees onto roofs.
  • If squirrels are gaining access by traveling on wires attached to your house, install 2-foot sections of 2- to 3-inch diameter plastic pipe over the wire. Slit the plastic pipe lengthwise, spread it open and place it over the wire. The pipe will rotate on the wire and cause squirrels to fall off. Never install this type of wire guard on or near electric lines. If a power line is the travel path being used, contact your electric company for assistance.
  • Tactile repellents, e.g. Squirrel Scram, on railings, columns, and other surfaces may deter squirrels from climbing. WARNING: These products are known to entrap and kill small birds, are messy, and can stain building finishes so use caution. Apply masking tape to the area you want to protect, and then apply or brush over the masking tape. These products work by sticking to the squirrels’ feet, which frustrates the animals and causes them to avoid the area.
  • To ward off chewing squirrels, apply the taste repellent Ropel to siding, outdoor furniture, fences, garbage cans, window screens, around repaired holes, and on trees and shrubs.
  • You should see similar results odor and taste repellents outdoors around flower beds, potted plants, and on bulbs to prevent digging and feeding. 

Laws and regulations to be aware of

While we attempt to provide guidance about state and federal regulations pertaining to specific species and control techniques, we do not provide information about local jurisdictions (city, town, county, etc.) where regulations may be more restrictive, especially as it applies to discharge of firearms, transport of animals or use of trapping equipment. Contact your local city or county government to inquire further. No guarantee is made that information (or lack of information) associated with a species or control technique is completely accurate or current. You should become familiar with federal, state and local laws before beginning any wildlife control activities.
