Confirm what it is, find how it is getting in, check for cable damage — and resist the strong urge to block the hole, because that is how a bad situation becomes a worse one.
Confirm the animal, locate the entry point, and check for gnawed cabling. Then call someone — trapping is £280, and rodent treatment is £190 to £240 if it turns out to be rats or mice.
Do not block the entry hole. It is the instinctive response and it is the wrong one, for reasons set out below.
This costs nothing and is the most useful diagnostic available. Over three or four days, note the times you hear activity.
| Pattern | Most likely |
|---|---|
| Daytime, especially early morning and late afternoon | Squirrel |
| After dark, quietening by dawn | Rats or mice |
| Constant, high-pitched, with calls | Birds |
| Dawn and dusk, heavy and intermittent | Squirrel |
| Light, fast skittering at night | Mice |
Squirrels are diurnal, rodents largely nocturnal. Heavy thumping in the middle of the afternoon is about as clear an indicator as you will get without seeing the animal.

Only if you can get up there safely and there is boarding to stand on. If not, skip it and tell us.
Do not disturb a nest, and do not handle droppings or fouled insulation without gloves and a mask.
This is the instinctive response, and it is the one that turns a manageable problem into an expensive one.
A squirrel sealed inside a roof space will gnaw at whatever stands between it and the outside. That means cabling, pipework, timber and plasterboard — and if it does not get out, a dead animal somewhere you cannot reach.

Properties in Harrow Weald HA3 with mature trees close by and timber soffits are the classic setup for this. If you have both, the soffit is where to look first.
Possibly — birds in a roof space are usually higher-pitched, more constant, and often accompanied by calls. Nesting birds have legal protections, so it is worth establishing which you have.
Not reliably. A warm dry roof space beats anything available outdoors.
Not directly, provided you do not try to handle it. The risk is to the building — cabling above all.
Roof spaces attract wasps as well — and that is a £90 fixed cost in Harrow Weald, with our guaranteed service.
Note the times you hear activity over a few days. Daytime noise points to squirrels; night-time to rats or mice.
No. A squirrel sealed inside will gnaw at cabling, pipework and timber trying to get out — and if there are young, it creates a welfare and smell problem.
Gnawed cabling first, then damaged pipes, torn insulation, droppings and daylight showing at the eaves.
We would not recommend it. A cornered squirrel bites and is strong for its size.
No. Rodenticides are not appropriate for squirrels and misuse carries legal consequences.
Possibly — birds are usually higher-pitched and more constant, often with calls. Nesting birds have legal protections.
Not reliably. A warm dry roof space is better than anything outdoors.
Squirrel trapping is £280. If it turns out to be rats or mice, treatment is £190 for a flat or £240 for a house.
