Squirrels – Don’t let them drive you nuts!

When we think of animals belonging to the rodent family, often times, squirrels are not top of mind. Probably the most aesthetically pleasing of their kind, they are almost always seen nibbling on something to eat due to their constantly growing teeth. This gives them somewhat of an endearing quality along with their bushy tails and playful movements, often depicted in movies as cute and friendly creatures. Seen scampering up trees and daringly traversing a telephone line or two, squirrels are disregarded as nothing more than part of the scenery.

However, squirrels that find themselves near to or even inside your home, can cause serious damage and wreak havoc in your garden, furniture and more dangerously, electrical wiring and support beams in your house. Once squirrels settle in an area, they are very difficult to get rid of and will make themselves comfortable. Similar to rats and mice, they make excellent climbers, which means that entering your home through the attic or chimneys does not pose much of a challenge for them.

Types of Squirrels


Ground Squirrels

Ground squirrels stay true to their name and mainly roam on lower level surfaces. Although they can climb, the ground squirrel will always opt to hide in burrows when they are threatened or frightened. Primarily active during the day, ground squirrels prefer warm, sunny weather and will hibernate during the colder months. Ground squirrels live in colonies and will spend their time storing food, resting and rearing their young. They will usually forage for food near to their burrows, which is why they mainly inhabit areas that are close to buildings or bordering farms and crops. Feeding on a diet mainly consisting of grains, nuts and seeds, ground squirrels are voracious in their appetite for grasses and plants especially after they emerge from hibernation.

Damage caused by ground squirrels

Ground squirrels can cause major damage in and around gardens, farms and crops. Feasting on plants, both food-bearing and ornamental, ground squirrels can devour fruit and nut trees, vines, shrubs and vegetables. They will even gnaw on irrigation systems and sprinkler heads, making their presence a nightmare for homeowners and farmers.

Their burrowing habits can also prove detrimental to livestock, humans and machinery as the uneven surface makes it difficult to walk on, also causing damage to the machinery. Burrows can pose structural problems, affecting the moisture level in tree roots, often causing them to fall over as well as interfering with the structural stability of buildings. If there are excessive colonies of ground squirrels in any one area, the chances of the spread of disease is also high.

Tree Squirrels

There are several types of tree squirrels that are commonly found near homes. Although they primarily inhabit wooded areas, residential and commercial development has caused them to seek new places to live (including your attic!)

Some of the more commonly seen squirrels are:

  • Gray squirrels – Typically found in rural areas that are densely populated with trees. Gray squirrels can wreak havoc in your backyard by digging holes in the ground and flower beds to bury acorns. Feeding nuts and seeds, they will not hesitate to overthrow your bird feeder to get to the seeds!
  • Fox squirrels- Prone to nesting in trees and hollowed out trunks, the fox squirrel can also do damage in your garden, destroying flowers, plants and fruit trees.

Damage caused by Tree squirrels

Much like their more undesirable counterparts, rats and mice, tree squirrels use their superior climbing skills to find ways of entering your home and setting up residence in your roof or attic. A good way to determine if you may have a possible squirrel infestation is to know what signs to look out for:

  • Since tree squirrels are excellent climbers, checking the higher level areas of your home are essential. Taking a good look inside your attic for evidence of damage to insulation, wood beams or electrical wiring. This is especially important as chewing of these wires can cause shortages and result in home fires.
  • If you notice small holes in your yard, chances are squirrels have been busy hiding their food throughout your exterior space.
  • Scratching sounds coming from your attic could be a sign that squirrels have entered your home. If there are utility lines near to your house, this is a good indication that squirrels may have found their way to your roof, and then into your attic as these guys are not afraid of running across high wires.

Some of the ways that squirrels can cause damage in and around your home are:

  • Chewing on electrical wiring
  • Gnawing at support beams in your attic or under your home.
  • Ripping apart insulation, window and door frames
  • Destroying bird feeders, potted plants and flowers
  • Squirrels that carry diseases, as well as squirrel fleas, can pose serious health risks.

Control & Prevention

While an overturned potted plant, or a few holes in your garden may be more of a nuisance than anything else, the prospect of squirrels chewing on electrical wires or beams is far more attention worthy. Even one squirrel that has entered the home can cause major issues. Controlling these erratic creatures can be quite the challenge and if you suspect that there may be a possible infestation, it is important to contact your pest service professional. As with other rodents, keeping squirrels away from your home is key and your pest control expert may apply certain exclusion and trapping techniques to prevent squirrels from entering and capturing those that have already found their way inside. As with any rodent, trapping and removal of squirrels is best left to a professional.

Some ways that you can help keep squirrels away from your home are:

  • Trim branches or trees that may be close to your roof line to avoid giving squirrels easy access.
  • Repair any openings or holes under gutters, on your roof and around the perimeter of your house.
  • Remove any bird feeders that are near to the home as these can attract squirrels looking to establish a food source.

Always contact your pest control professional if you think that the problem is beyond your control. Your service expert is trained to provide the best advice and procedure for keeping your home squirrel free.
