Spiders are not evenly spread through a Finchley house divided into flats. The basement and ground-floor flats, with windows close to the ground, doors onto the garden and cooler, sometimes damp rooms, collect far more of them than the flats upstairs.
If webs keep building up in the same rooms, book spider treatment at £180 for the first room and £60 for each additional room. Call 0800 955 2347.
Spiders follow insects, and insects gather at ground level, in plants, soil, damp paving and the light from windows. A flat at or below ground level in a converted period house has all of that on its doorstep. Its windows open onto the garden or front path, its walls meet the soil, and its rooms are often cooler and quieter than the rest of the house. What attracts spiders into a property explains the pull.

Where a house has a lower-ground or basement flat, the front windows may look out onto a small sunken area with steps down from the path. Leaves, damp and insects collect there, and so do spiders, which then find their way in round the window frame or under the door. Rooms with little light and some damp suit the insects that spiders eat.
The ground-floor flat usually has the back garden, a door or French windows onto it and perhaps a shed. Webs build up around the garden door, the corners of the kitchen in the rear addition and the window reveals. Where the suspended floor has gaps at the skirting, spiders use the void beneath.

The noble false widow is a glossy, dark brown spider with a rounded body that likes gaps around window frames and door frames. Bites are uncommon and are usually likened to a wasp sting. If a bite swells badly or looks infected, speak to a pharmacist or GP, and call 999 for signs of a severe allergic reaction. Are there dangerous spiders in Barnet homes? has more.
In late summer and autumn, male house spiders wander in search of a mate and turn up in baths and running across floors. A few each autumn is normal in a garden flat. A build-up is different: webs, egg sacs and spiders in the same rooms week after week. Why spiders keep appearing in the same rooms helps you tell the difference.
Treatment is aimed at the rooms where spiders have built up and can bring numbers down. It will not stop spiders walking in from the garden or the front area, and it does not change the damp or the insects that drew them. If lots of spiders are feeding on another pest, such as carpet beetles or small flies, that needs dealing with too, as whether lots of spiders mean another pest explains. Ants trailing across a garden flat's kitchen are covered on ant control in Finchley.
Spiders from outside will still appear now and then, especially in autumn and after a spell of wet weather. If they build up again in the treated rooms, get back in touch and tell us which rooms.
