Grey Squirrels: Garden Pests or Home Wreckers?

Grey squirrels present a multi-faceted threat, impacting native wildlife, gardens, and even homes. These invasive creatures have been observed preying on songbird eggs and chicks, leading to an estimated 15% reduction in fledging rates. Their destructive habits extend to agricultural settings, where they damage crops, bulbs, and seeds, posing a threat to orchards and market gardens.

Beyond environmental damage, grey squirrels can infiltrate homes, causing harm to insulation, wires, and structural elements like thatched roofs. They are also directly responsible for the decline of native red squirrels by outcompeting them for resources and spreading a lethal squirrel pox virus to which red squirrels have no immunity.
