Squirrels are a member of the rodent family and are common in many parts of the world. They easily adapt to humans and therefore live in developed areas. They spend much of their time scurrying around looking for food. Squirrels are arboreal, which means they usually make their homes in trees. Sometimes however, squirrels may damage trees by chewing on its bark and often times, squirrels use trees as a means to get into a house to nest, primarily in the attic. Whatever the reason, there are several approaches to getting rid of squirrels in trees.
Install a 12 to 18 inch wide piece of sheet metal on the tree trunk about four feet above the ground. Attach the sheet metal to itself, not the tree. Also, do the same for any surrounding trees that give the squirrels access to the tree you are concerned about. You can also trim the branches of surrounding trees to cut off access. However, if the tree is near a house, power lines, or any other structure that give the squirrels access to the tree, this method will not work.
Use moth balls. Place several moth balls in nylon stockings and hang about a foot down off the branches throughout the tree. If it a fruit tree, hang several near the heavy clusters of fruit. If you know where the squirrel's nest is, hang extra near the nest. Since moth balls are toxic, be sure to use caution and never leave them in reach of children or pets.
Use Ro-Pel. This product is non-toxic and designed to get rid of rodents due to its bitter nature. It comes in a spray form and is safe on trees. Follow the directions and all precautions on the label to apply to your tree.
Set up a trap. You may need a permit to trap a squirrel so contact your local animal control to find out. Generally, a five by eighteen inch trap will suffice. Open the trap and place peanut butter on the trip lever. Follow manufacture instructions for setting the spring loaded door, which usually involves just locking two pieces of metal together that will snap apart to close the door when the lever is pushed.
