Read the next section before booking. Spiders are the one pest where we most often tell people they do not need us, and we would rather say so on this page than after taking your money.
Spiders are not a hygiene risk, they do not damage buildings, and no spider found in a British home is a danger to a healthy adult. They also eat flies, mosquitoes and other insects, which is a service rather than a nuisance.
Most people who search for spider control have a normal number of spiders and a strong dislike of them. That is an entirely reasonable feeling, and it is not something a chemical treatment resolves well — because the spiders you object to are mostly coming in from outside, and treatment does not stop them arriving.
We will happily take a booking for persistent spider activity. We will not sell you a treatment because you found three spiders in September, and we would rather tell you that here than on the doorstep.
Most spider enquiries arrive between late August and October, and there is a simple explanation. Those big house spiders sprinting across the carpet in the evening are mature males looking for a mate.

It is a few weeks, it happens every year, and it ends on its own. Treatment in September is treating a calendar.

What it does not do is create a permanent barrier. Spiders will continue to come in from outside through the same gaps they always used, so treatment reduces rather than eliminates, and it works best combined with the physical measures below.

Tenants report spiders frequently, and honestly most of those reports do not need treatment. Where a property has genuinely heavy persistent activity — often an empty property, a cellar or an outbuilding — the published room pricing applies as normal.
No spider found in a British home poses a danger to a healthy adult. False widows can bite if handled or trapped against skin, and the result is typically comparable to a wasp sting. Reports of anything worse are almost always secondary infection rather than venom.
No. The conker remedy is folklore with no supporting evidence, and peppermint oil is no more reliable.
It reduces the population and remains active for a period. It does not seal the building, so sealing gaps and reducing insects is what makes the difference last.
A pest that genuinely does need dealing with — wasp nest treatment in Harrow Weald is £90 fixed cost, guaranteed.
£180 for the first room and £60 for each additional room.
Often not. A few spiders in autumn is normal seasonal activity that ends on its own. Treatment suits genuinely persistent heavy activity.
They are mature males looking for a mate. They have usually been around all year and are only conspicuous now because they are moving.

No. It is folklore with no supporting evidence.
Reducing the insects spiders feed on — especially around outside lights — sealing gaps, and clearing webs regularly.
