Loft insulation is one of the quieter casualties of a squirrel infestation. Homeowners in Thatcham often focus on the noise or the visible mess, but the damage happening to insulation underneath it all can have a real effect on energy bills and comfort long after the squirrels themselves are gone.
How squirrels damage insulation
- Shredding — squirrels tear insulation apart to use as soft nesting material, particularly when preparing for young
- Compacting — repeated movement across the loft floor flattens fluffy insulation, which significantly reduces its thermal performance
- Fouling — droppings and urine soak into insulation, which is both a hygiene issue and a source of persistent odour
- Displacement — insulation gets pushed aside or piled up as squirrels create routes and nesting areas around the roof space
Why compacted or soiled insulation matters
Loft insulation works by trapping air, so its effectiveness depends heavily on it staying loose and evenly spread. Once it's compressed or matted from nesting activity, it loses much of its insulating value even though it's still physically present — which means a homeowner can end up paying more to heat the house without any obvious sign that the insulation itself is the problem. Soiled insulation also isn't something you want sitting directly above living spaces indefinitely.
What to check once squirrels are removed
After squirrels have been cleared from a Thatcham loft, it's worth having the insulation properly assessed rather than assuming it's fine because it's still there. Areas near known nesting sites or well-used runs are the most likely to need replacing, while insulation further from the activity may be untouched.
Squirrel damage to insulation is often more extensive than it first appears, especially once you factor in fouling that isn't visible without moving material aside.
