The Honest Bit First

Spiders are not a hygiene risk, 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 searching for spider control have a normal number of spiders and a strong dislike of them. That is a reasonable feeling and 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 treat genuinely persistent activity. We will not sell you a treatment because you found three spiders in September, and we would rather say that here than on the doorstep.

When Treatment Is Genuinely Appropriate

When it is not

The Autumn Question

Most spider enquiries arrive between late August and October, and there is a simple explanation. The big house spiders sprinting across the carpet in the evening are mature males looking for a mate. They have usually lived in or near your house all year; they are conspicuous now because they are moving.

A few weeks, every year, ending on its own. Treatment in September is treating a calendar.

What Treatment Actually Does

Applied to the places spiders rest, walk and web — corners, behind and beneath furniture, window and door frames, around entry points — it reduces the population in the treated rooms and remains active for a period.

What it does not do is create a permanent barrier. Spiders continue to come in from outside, so treatment reduces rather than eliminates and works best combined with physical measures.

For Landlords

Tenants report spiders frequently and 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.

Are any UK house spiders dangerous?

No spider found in a British home poses a danger to a healthy adult. False widows can bite if handled or trapped against skin, typically comparable to a wasp sting. Reports of anything worse are almost always secondary infection rather than venom.

Do conkers work?

No. It is folklore with no supporting evidence.

Will treatment stop them returning?

It reduces the population for a period. It does not seal the building.
