Loft insulation is one of the first casualties when grey squirrels move into a roof space, and it's a question we're asked regularly by Pangbourne homeowners once they've spotted disturbed insulation during a loft visit. The short answer is yes, squirrels can and do cause significant damage to insulation - and it's rarely limited to a small patch.
Why Squirrels Target Insulation
Squirrels don't damage insulation out of spite - they use it as raw material. Soft, fibrous loft insulation is ideal for lining a drey, so squirrels will pull it apart, drag it into a pile, and pack it into a corner or against a water tank to build a warm, dry nest, particularly ahead of the winter and midsummer breeding seasons.
The Practical Consequences
- Flattened or displaced insulation loses much of its thermal efficiency, which can push up heating costs
- Torn and compacted insulation no longer provides even coverage across the loft floor
- Nesting material and debris can end up contaminating stored items in the loft
- Droppings and urine soaked into insulation create odour and hygiene issues
- Insulation dragged near electrical cabling can obscure damage that's harder to spot until it becomes serious
It's Rarely Just the Insulation
Where we find insulation damage in a Pangbourne loft, we nearly always also check the timber and any cabling running through the same area, because squirrels gnawing to build a nest often go on to gnaw structural timber or cable sheathing nearby. Insulation damage is frequently the visible symptom of a wider problem rather than the whole story.
What Happens After Squirrels Are Removed
Once a squirrel infestation has been dealt with, damaged insulation typically needs to be assessed and, in many cases, replaced or topped up to restore proper thermal performance. Contaminated insulation removal is also worth considering on hygiene grounds, particularly in lofts used for storage.
If you've found torn or displaced insulation in your loft, it's worth having the roof space properly checked rather than just tidying it up. Contact Pest Services Berkshire to inspect your Pangbourne property, confirm whether squirrels are the cause, and advise on next steps.
