Squirrel Key Facts
  • Grey squirrels Sciurus carolinensis are invasive pests, not native to the UK.
  • Grey squirrels are also responsible for the decline in native red squirrel Sciurus vulgaris numbers
  • As well as causing physical damage and noise complaints, like other rodents, squirrels can cause contaminations.
  • Like a rat a squirrels teeth are always growing
  • Squirrel often enter home through holes in roofs. where they can be found taking insolation and damaging wood and boxes
  • The Squirrel

    A common pest problem is when squirrels get into the loft space of a building, as they can cause structural damage particularly to loft insulation, timbers, pipework and any stored items.

    This in turn can pose a significant fire hazard when insulation on electrical wiring is stripped. Squirrels may be noisy, and are often known to drown in uncovered water storage tanks, which may contaminate the water supply.

    For squirrels, prevention is certainly better than cure, but as they only need a hole the size of the squirrel’s head to gain access to a building, prevention can be challenging.

    If squirrels have actually been seen entering a property their access points will be clear, but otherwise narrowing down their routes can be difficult. Stuffing a piece of newspaper into a suspected access hole will be easily removed by a squirrel, and this will reveal that the hole is in use.

    The RSPCA advice recommend strong wire mesh size no larger than 25mm to block access holes to squirrels, as well as repairing slipped slates, rotten soffits or missing bricks.

    Squirrel Pest control


    Grey squirrels can cause damage when they enter roof spaces of houses and buildings. For example, they can:

    • Chew on woodwork and ceilings
    • Strip insulation from electrical wires
    • Tear up fibreglass insulation 
    • Contaminate cold water tanks with urine and droppings.

    People also report sleep issues due to the loud noises they make at night while they’re scuttling around your attic. Squirrels are most active before sunrise, especially in winter, but ends well before sunset.
