Grey Squirrels (Sciurus Carolinensis) are a non native species brought into this country for the amusement of landowners at the beginning of the Victorian era. Like many other species we have had the naiveté  to introduce, the grey squirrel has gone on to cause wholesale destruction to our native flora and fauna, while additionally causing damage and risk to homes and businesses.

A few Grey Squirrel facts…

  • This species is native to the eastern part of North America.
  • The first recorded sighting of the Grey Squirrel ‘in the wild’ was at Llantysilio Hall in Denbighshire in October 1828.
  • In 1938 it was declared illegal to import any more Grey Squirrels in GB, but unfortunately the squirrel was already well established.
  • Where inhabiting the same ranges, the Grey Squirrel causes the extinction of our native Red Squirrel (Sciurus Vulgaris) through competition for food and territories. Sadly the grey also carries and transfers a pox virus – fatal to Red Squirrels but fairly harmless to themselves, that exponentially increases the replacement of the reds.
  • Grey Squirrels like to take eggs and fledglings from nesting birds.
  • The Greys are known to cause ring barking in young stock trees and there is marked loss and damage to trees from bark stripping leading to exposure to disease/pests where grey squirrel inhabit.
  • Grey Squirrels are a risk to homes and businesses though chewing of wires, water pipes, timber framework and insulation.


Here at Landguard Pest Control we understand these little guys look cute and cheeky. But aside from the aforementioned impacts, these rodents just do not naturally belong here. Control of the species is promoted by the Government through DEFRA and the Non-Native Species Secretariat. Landguard has also worked with the Red Squirrel Survival Trust in Cumbria.
