If you've been up into the loft and found insulation pulled apart, compressed into clumps, or dragged into a corner, that's one of the clearest physical signs of squirrel activity we see on inspections across Earley. It's not random destruction — it's purposeful nest building.
Nesting Behaviour Explained
Grey squirrels build nests called dreys, and while their natural drey is constructed from twigs and leaves high in a tree, a loft space offers something better from the squirrel's point of view: shelter from weather and predators, and soft, warm material already lying around in the form of loft insulation. Fibreglass or mineral wool insulation gets torn up, balled together, and shaped into a nesting site, often tucked into a corner or against a chimney breast for extra warmth.
The Knock-On Effects of Insulation Damage
- Reduced thermal performance, meaning your loft insulation stops doing its job properly and heating bills can creep up
- Insulation compressed or displaced from where it needs to sit evenly across the loft floor to be effective
- Contamination of remaining insulation with droppings and urine, which can create odour issues and isn't something you want to handle without care
- Insulation pulled away from areas around pipework, increasing the risk of frozen pipes in winter
- Ongoing damage that continues as long as squirrels remain in residence, rather than a one-off event
Replacing Insulation Without Fixing the Cause
It's tempting to simply top up or replace damaged insulation once you notice the problem, but doing that before the squirrels are removed and the entry point is sealed just means the new insulation gets shredded too. Dealing with the cause has to come before dealing with the damage.
If your Earley loft insulation looks like it's been through a storm, it's worth having it checked before you spend money replacing it. Pest Services Berkshire can confirm whether squirrels are responsible, remove them, and advise on next steps so any insulation work you do actually lasts.
