Squirrels are not generally considered to be pests because you usually see them roaming around open park areas and up trees, although sometimes the more rural neighbourhood will infringe a Squirrel Habitat.
Squirrel Habitat
Squirrels can be a very real threat to your home and lifestyle if you live in the right sort of environment to support a squirrel habitat.
Because the natural squirrel habitat is constantly shrinking, more and more often is the likelihood that you will encounter this animal in your neighbourhood. Indeed, it is not unlikely your attic, chimney or crawlspace could become a squirrel habitat!
The problems squirrels and the squirrel habitat generate mainly come from the fact that they like to chew things and can get into very small places often liking to explore new areas.
Gnawing through loose roofing and foundations, or slipping through chimneys and other existing holes means a squirrel habitat can very quickly set up and wreak havoc on your home. 
During the mating season you will be able to hear them and often the sounds of scurrying will become a night time nightmare.
Problems Caused by Squirrels
The more uncommon, although still likely, possibility that a squirrel habitat can cause is a serious health risk to humans.
Squirrels are commonly the primary carriers of tick fever, powassan encephalitis, and rabies. The insects that live on the squirrels can also carry all kinds of nasty micro-organisms and disease.
This is one of the reasons home owners should never attempt their own Squirrel Control solutions. While squirrels have become accustomed to humans, ones that appear particularly fearless around you may be rabid and should definitely be avoided.
Among the many pests a squirrel habitat can bring into your home, ticks and fleas are almost surely present, leading to pet infections as well.
Squirrel Control
Like with many of the other pests encountered in the home it is a very good idea to get a professional to deal with squirrel control because of the likelihood of disease and the fact they will have the correct tools and knowledge to deal with the problem quickly and effectively.
You may well be able to trap or kill one or two squirrels, using a more effective method of squirrel control such as an expert would use will prevent problems such as dead offspring rotting in your attic.
The health risk and the common pitfalls that arise from taking squirrel control into your own hands simply aren't worth it. Squirrel Control Professionals have many ways they can deal with your squirrel problem.
They can trap and kill the squirrels, trap and relocate the squirrels, deploy Squirrel Repellent and even use specially-designed lighting equipment to drive the squirrels away.
Keeping Squirrels Out of your Home
After your squirrel problem has been addressed you should do your best to seal any structural weaknesses in your home, especially the roof and installing a chimney screen.
Be aware, though, that even the most effective treatments may not prevent future infestations if you live in a place desirable for a squirrel habitat.
