Why Do Grey Squirrels Problems Keep Coming Back in Greenwich Properties?

A Vacated Territory Does Not Stay Vacant

This is the fact that explains almost every squirrel recurrence.

Grey squirrels are abundant across suburban south-east London, and a warm dry roof void with an accessible entrance is a desirable place to be. Removing the animals that were using it does not make it less desirable. It makes it available.

So a cleared loft with the entry point still open is not a solved problem - it is a vacancy. The interval before something else finds it depends on the local population and the time of year, and in an area with mature tree cover it can be short.

The programme deals with the animals. The entry point decides whether that matters six months later.

1. The Entry Point Was Never Closed

The commonest reason by a wide margin.

Proofing is quoted separately at £180, up to 1 hour and carried out after the loft is confirmed clear - never before. Where it is skipped, the roof void stays available. Where the opening is a rotten soffit, a failed verge or displaced tiles, that is a roofing repair rather than proofing, and a roofer will quote it.

Either way, something has to close. A trapping programme without a repair at the end is half the job, and we will say so rather than let you believe otherwise.

2. The Road Is Still There

The half that gets forgotten even when the hole is closed.

Squirrels reach a roof along branches, fences, cables and neighbouring roofs. Closing one opening on a building that a branch still reaches means the next animal arrives at the roof and looks for a different way in - and an older roofline usually has more than one weak point.

Cutting back an overhanging branch is the single most useful thing a householder can do, and it is the intervention most likely to change the long-term picture. Where the route is a cable or a neighbour's tree, it is worth at least knowing that is what you are dealing with.

3. In a Terrace, the Entry Point May Not Be Yours

Where a run of terraced houses has a continuous roof void, animals can enter at a defect four doors down and be heard above your bedroom.

Sealing your own roofline in that situation achieves nothing except a false sense of having dealt with it, and it is the reason the survey looks further along the run than the house the noise is in.

The practical answer involves the neighbour, or in a managed block the freeholder or managing agent. A report describing where the entry actually is is what makes that conversation productive.

4. Nothing Changed Above the Ceiling

A less obvious contributor. A roof void that offers deep insulation, undisturbed space and no human presence is more attractive than one that is used for storage and entered regularly.

That does not mean filling your loft with boxes to deter squirrels. It does mean that a completely undisturbed void on a property with mature trees is always going to be a candidate, and the entry point matters more there than anywhere.

The Seasonal Pattern People Read as Recurrence

Squirrels use lofts most in the colder months and around breeding. A property can be genuinely quiet through the summer and busy again from autumn without anything having failed.

The way to tell the difference: if the entry point was closed and the loft confirmed clear, autumn activity means a new opening or a different route. If it was never closed, autumn activity is simply the vacancy being filled.

The Damage That Accumulates While It Recurs

Worth stating because it is the real cost of leaving the cycle running, and none of it is our invoice:

• Cable insulation. Gnawed repeatedly by each successive occupant. A genuine fire risk, and worth an electrician's attention.
• Insulation. Torn up and compressed, which reduces its performance as well as making a mess.
• Water. A roofline opening lets weather into the void whether or not an animal is currently using it, and that damage continues quietly for as long as the hole is open.
• Timber. Gnawing on joists, rafters and boarding.

What Ends It

Two things, in this order, and neither works alone:

1. Close the building properly. Proofing where the opening is a proofing job; a roofer where it is a roofing one. After the loft is confirmed clear, not before.
2. Remove the road. Cut back the branch, or at least know that the cable or the neighbour's tree is the route, so the next inspection starts in the right place.

Done together, that is what turns a recurring annual problem into a one-off - and it is a considerably better outcome than a trapping programme every winter.

The Three-Year Comparison

Worth setting out, because the choice between closing the building and repeating the programme is usually made on the first year's figures alone.

The second row costs more in year one and less across the three, and that is before counting the damage that accumulates while the first row runs: insulation torn up repeatedly, cable gnawed by each successive occupant, and weather entering through a roofline opening that stays open the whole time.

Where the opening needs a roofer rather than proofing, the arithmetic still favours the repair - it is simply somebody else's invoice. What does not make sense in any version is a trapping programme every winter with nothing closed at the end of it.
