Squirrels that make their nest in homes, wreak havoc since they use pieces of house to build their nest. A squirrel's teeth are constantly growing so they have to continuously gnaw to wear them down. They can chew through wood, wiring, and even plumbing.
A pest control professional will trap and dispose of the animals once caught. Once squirrels have established a nest, they do not give it up easily, you can seal up the openings where they get in and out, and they will chew a new hole through the wall to get back in. They must be removed permanently.
Once the house is squirrel-free, it is time to seal gaps in the exterior. Common problem areas are eaves, soffits, cornices, and entry points for wiring and pipes, as well as gaps along the foundation. Loose flashing and siding should be repaired, small cracks caulked tight, and large holes filled with wood, sheet metal, or wire mesh. All vent outlets for dryers, bathrooms, and attics should be covered with metal screening and chimneys capped.
Remove the temptations that attract squirrels, such as bird feeders, and eliminate their means of getting to the house, overhanging tree limbs should be cut back ten feet from the house. Utility lines need to be squirrel proofed wires tougher. Slice a two-foot length of PVC pipe along its length and slide it over the wire. When a squirrel attempts to cross it, the tube will twirl and the squirrel will lose its balance.
Home owners frequently request that captured wildlife be taken away and released into nature. This is not a good idea because the squirrel may return and re-infest the house, squirrels can find their way back from as far away as ten miles.
In many parts of the country, there are laws against transporting live wildlife. They must be euthanized, his is more humane because trapping and releasing an animal often dooms it to starve.
In houses, fifty percent of unsolved fires are possibly caused by squirrels nibbling on the electrical wires.
