Harrow is best known for the semi-detached suburbia built up along the Metropolitan line, but the borough also has an older hilltop core and denser streets near its stations, and the pest problems follow the buildings.

Pinner, Rayners Lane, Kenton and much of Harrow Weald are classic 1930s semi-detached Metroland housing, built with gardens front and back. Wasps nesting under the eaves, squirrels using nearby trees to reach the roof, and ants coming in at patio doors are the typical calls from houses of this age and layout.

The hilltop around Harrow-on-the-Hill is older Georgian and Victorian building stock, predating the Metroland expansion around it. Carpet moths and beetles settle into original wool carpets in the larger houses here, and spiders build up in the cellars that are more common in housing of this age.

Around Harrow and Wealdstone stations, and along the High Street, housing is denser, with flats above shops and smaller terraced streets. Cockroaches follow warm pipework through these buildings, and bed bugs and fleas move between flats more readily than they do in the semis further out.

Stanmore and the northern edge of the borough have larger houses and gardens close to open Green Belt land. Rats and squirrels move in from this open ground more readily here than elsewhere in Harrow, so call 0800 955 2347 with the type of property and what you've found.

Rats turn up in gardens backing onto the Metropolitan line embankments, and along older drain runs near Wealdstone.

Mice move easily between the semi-detached houses of Harrow's Metroland suburbs, running along party walls into next door.

Nests appear under the eaves and in shed roofs of the borough's classic 1930s semis. One fixed price, with our 30-day guarantee.

Bed bugs spread between flats near Harrow and Wealdstone stations, so we always ask how many rooms are affected first.

A common end-of-tenancy problem in the flats around the main stations, once a previous pet's eggs hatch for the next occupant.

Cockroaches follow warm pipework through the shops and flats around Station Road and Wealdstone High Street.

Ants come in through patio doors and low gaps, typical of the semi-detached houses with gardens across most of the borough.

Mature trees along Harrow-on-the-Hill and in Stanmore's gardens give squirrels an easy route onto nearby roofs.

Carpet moths do well in the older Georgian and Victorian houses on Harrow-on-the-Hill, in carpets and rugs left undisturbed.

Larvae collect in floorboard gaps and under fitted carpets in the borough's semis, and are easy to mistake for moth damage.

Spider numbers build up in garages, cellars and loft rooms that are common across Harrow's 1930s housing stock.
These prices hold across the whole of Harrow — no postcode surcharges.

Wasp nests in Harrow most often turn up under the eaves of the borough's Metroland semis and in sheds and garden walls behind them. Treatment is charged at a flat £90, and if the nest is still active within 30 days, we come back at no extra cost.
Proofing is charged at £180 for up to one hour, small holes. It suits accessible gaps around a property that could be letting rats or mice in.
In Harrow's semis, gaps under bay windows, around extensions and at airbrick level are the entry points we most often find.
Near Harrow-on-the-Hill's older houses, gaps where pipes pass through original brickwork tend to be the issue instead.
