The most common types of squirrels involved in human-wildlife conflicts in North America and Europe include:
Eastern Gray Squirrel (Sciurus carolinensis): The most common tree squirrel in urban and suburban areas of North America and an invasive species in the UK and Italy.
Fox Squirrel (Sciurus niger): Larger than the gray squirrel, common in the eastern and central US.
Red Squirrel (Sciurus vulgaris): Native to Eurasia, its numbers have declined in the UK due to competition with the gray squirrel.
American Red Squirrel (Tamiasciurus hudsonicus): A smaller, territorial squirrel found in coniferous forests of North America.
Flying Squirrels (Genus Glaucomys): Nocturnal and gliding, they often inhabit attics.
While squirrels are often seen as charming park animals, they can become significant pests when they encroach on human habitats.
1. Property Damage
This is the most common and costly issue.
Attic Infestation: They seek out attics for nesting, causing a range of problems:
Chewing Wires: This is a major fire hazard. They gnaw on electrical wires, internet cables, and PVC pipes.
Structural Damage: They chew on wood beams, siding, and roof vents to gain entry.
Insulation Damage: They soil and tear up insulation with their urine and feces, reducing its effectiveness and creating odors.
Noise: Scratching, scurrying, and rolling nuts in the ceiling can be a significant nuisance.
2. Agricultural and Garden Damage
Crop Raiding: They dig up newly planted seeds, eat corn, and damage orchards by feeding on fruits and nuts.
Garden Destruction: They dig up flower bulbs, eat tomatoes, berries, and other garden produce.
Bark Stripping: They can girdle and kill trees by stripping bark from branches and trunks.
3. Bird Feeder Dominance
Squirrels are notorious for raiding bird feeders, consuming large amounts of seed, and often damaging the feeders in the process. They can deter birds from visiting.
