Spider Control London
Professional Spider Treatment — Domestic & Commercial
While most spiders found in UK homes are harmless, large infestations cause significant distress and can indicate underlying insect pest issues that are sustaining them. False Widow spiders (Steatoda nobilis) — increasingly common across London — can deliver a painful, medically significant bite causing swelling, blistering and in rare cases systemic illness. Noble False Widows have been found across South and East London. Zeus Services provides professional spider control using residual insecticides that also eliminate the insect prey species sustaining spider populations.

How We Treat It
Our step-by-step treatment process, used by every Zeus technician on every visit.
Species Identification
We identify all spider species present, with particular attention to False Widow spiders (Steatoda nobilis). We assess the scale of the infestation and locate all key harbourage areas inside and outside the property.
Web Removal
All accessible webs are removed mechanically before chemical treatment. This forces any remaining spiders into contact with the treated surfaces and prevents new webs being built in the same locations.
Residual Insecticide Treatment
A professional residual insecticide is applied to all corners, skirting boards, window frames, door frames, loft spaces, garages and external wall surfaces. This kills spiders on contact and provides ongoing protection for weeks.
Prey Insect Reduction
Because spiders feed on insects, we also treat the property for the underlying insect populations sustaining the spider infestation. Eliminating the food source is essential to achieve a lasting result.
Frequently Asked Questions
Are False Widow spiders dangerous?
False Widow spiders (Steatoda nobilis) can bite when disturbed, causing localised pain, swelling and blistering. In rare cases bites can cause systemic symptoms including fever, sweating and chest pain. Medical attention should be sought if symptoms escalate. They are found across London and should be treated professionally.
Why do I suddenly have so many spiders in autumn?
In late summer and autumn, male spiders leave their webs in search of females, causing a visible increase in spider sightings indoors. This is natural seasonal behaviour. A large indoor infestation at any time of year warrants professional investigation.
Will spider treatment harm my plants or garden?
We use targeted residual insecticides applied to specific surfaces. We avoid spraying flowering plants and pollinators where possible. We will discuss any specific concerns about your garden before treatment begins.
Do I need to vacate during treatment?
We recommend vacating for 2–4 hours while treated surfaces dry. Pets and children should not come into contact with treated surfaces until they are fully dry. We will advise you on specific re-entry times before we leave.
Can spiders return after treatment?
The residual insecticide provides ongoing protection for several weeks. Spiders entering from outside may still be killed on contact with treated surfaces. Ongoing exclusion — sealing gaps, reducing exterior lighting — helps prevent re-entry long term.
