Discovering a squirrel nest, known as a drey, in your loft insulation is a clear sign of an established problem rather than a passing visit. Unlike a squirrel simply sheltering temporarily, a nest indicates the animal — often a breeding female — intends to stay and is likely to have young there or plans to soon.
What a Loft Drey Looks Like
Indoors, a squirrel nest usually looks like a rough, gathered mass of loft insulation, shredded cardboard, fabric or garden debris pulled into a bowl shape in a corner of the roof space. It's often warm to the touch and may have a distinct musty smell if it's been in use for a while. This is different from the twiggy outdoor dreys you might see high in a tree — indoor nests make use of whatever soft material is available in the loft.
Why Timing Matters
Grey squirrels can breed twice a year, typically with litters in early spring and again in mid to late summer, though timing varies. If a nest contains young (kits), the approach needs to account for that — separating a mother from dependent young without a plan for the kits isn't appropriate, and it's also likely to be less effective, since she'll attempt to retrieve them or the young may be left to die in situ, causing odour and further problems.
Why This Isn't a DIY Job
- Confirming whether a nest is currently occupied, and by how many animals, isn't always obvious from a quick look
- Grey squirrels are subject to UK wildlife law, which affects how they can lawfully be dealt with — professional pest controllers work within this
- Handling squirrels directly carries a risk of bites and scratches, and dreys can also harbour parasites such as fleas and ticks
- Removing a nest without addressing the entry point simply invites the same problem to repeat
What Happens After the Nest Is Dealt With
Once a loft is confirmed clear, the nesting material and any contaminated insulation typically need removing and the area cleaned before the entry point is permanently sealed. Skipping this step and just blocking the hole can leave odour, parasites, or damaged insulation behind that continues to cause issues long after the squirrel itself is gone.
