A garden that runs down to the brook is full of insects, and where there are insects there are spiders. By late summer the shed, the garden room and the window frames on the garden side of a Whetstone house hold far more of them than the street side.
Spider treatment here is £180 for the first room and £60 for each additional room, and you can ask about the shed when you book. Book a spider treatment or call 0800 955 2347.
Damp ground, long grass, hedges and the brook's own insect life feed a large spider population at the bottom of these gardens. The rooms that face them, and the outbuildings in between, are where spiders are seen most. The corridor and the other animals it brings are covered on Pest Control Whetstone.

Timber outbuildings opened only now and then give spiders dry corners, stacked pots and folded furniture to hide in, with insects coming in through every gap. Garden offices and summerhouses with glazed doors draw flying insects to their lights after dark, and web-building spiders follow. Indoors they pick similar quiet places, as where spiders hide inside homes describes.

Windows on the garden side, lit in the evening, attract moths and midges from the lawn and borders, and spiders spin across the frames to catch them. False widow spiders, now widespread in the south of England, often settle in the gaps round window frames, sheds and garden furniture. Reducing spiders around windows and doors has practical steps for frames on the garden side.

From late August into October, large house spiders turn up in baths, on carpets and along skirting boards. Most are males that have left their webs to find a mate. In a brook-side house the back rooms, the utility room and any room with a door onto the garden usually see the most, and the numbers fall away again as the weather gets colder. Older cottages, with gaps round old doors and windows, tend to let in more than a well-sealed flat above the High Road. Why there are so many spiders in the house explains more.
Treatment reduces the spiders in the rooms and buildings that are treated. It cannot stop spiders living in the garden, the hedge or along the brook, and with that much habitat outside, some will always find a way in. The honest aim is fewer spiders in the places that matter to you, alongside the practical steps further down. Whether professional pest control can reduce spiders sets out what to expect.
A shed or room thick with webs may simply be telling you there is plenty for spiders to eat. Whether lots of spiders means another pest problem explains what to look for. Tiny cream larvae in a carpet or holes in wool could point to carpet moths, while small mottled beetles on a sill in spring may be carpet beetles.
When you book spider control, list the rooms you want treated and say whether a shed, garage or garden room should be included. Clear clutter from the corners and edges of those rooms, and pull stored items away from the walls of the outbuilding. If the shed or garden room is where the webs are thickest, say so, because it may be the most useful place to include. You will be told what to expect afterwards, and if numbers build up again, get back in touch.
Spiders across the rest of the borough are covered on Spider Control Barnet.

The garden side faces the hedges, long grass and the brook, which hold far more insects, and spiders gather where the food is. Book a treatment for the rooms that are worst.
A bite can be painful, rather like a bee or wasp sting, but serious reactions are rare. If a bite swells badly, looks infected or you feel unwell, speak to a pharmacist or GP, and call 999 for signs of a severe allergic reaction. Dangerous spiders in Barnet homes has more.
Tell us which outbuildings you want included when you book, and we will confirm how they are counted.
It reduces them in the treated rooms, but with so much habitat outside it cannot stop every one. Sealing gaps and cutting planting back from the walls helps keep numbers down.
Rooms with a door to the garden, a damp corner or little disturbance suit them. Why spiders keep appearing in the same rooms explains.
Spiders live in lofts wherever insects do. Why there are spiders in the loft covers what it means.
