Damage to Structures

The charm of Eastern Gray Squirrels often fades when their activities take a toll on structures. Their relentless gnawing on wood, plastic, and even electrical wiring poses a significant threat to homes and buildings. Attics and crawl spaces become prime locations for nesting, leading to potential structural damage and fire hazards resulting from wire-chewing. Identifying signs of structural compromise, such as chewed insulation or droppings in overlooked corners, is crucial for homeowners seeking to address and prevent damage caused by these industrious squirrels.

Managing Eastern Gray Squirrel Damage with Prevention and Control

Habitat Modification

In the ongoing dance between humans and Eastern Gray Squirrels, one effective strategy for damage prevention involves habitat modification. By manipulating the environment to make it less appealing to these nimble foragers, homeowners and land managers can discourage destructive behaviours. This might include strategically placing bird feeders, securing trash bins, and minimising easy access to potential nesting sites.
