Get Rid Of Spider Problems | Spiders Removal Specialists
Although spiders do good by eating flies many people have a real fear of the eight-legged creatures. It is for this reason PEST UK provides a service of treating spiders.
False Widow Spiders
“False widow” is a general term for any one of up to about 120 species of spider that resemble the notorious black widow spider. Steatoda Nobilis is the spider that has made headlines in the UK. It is sometimes also referred to as a “British black widow”, and is about the size of a 50 pence piece. Steatoda Nobilis is identifiable by its bulbous brown abdomen with cream coloured markings that often resemble the shape of a skull. It has a tawny body with reddish-orange legs.
How Dangerous Are False Widows?
Not very. False widows can bite but like all insect bites the reaction gates from person to person.
Where do they come from?
The false widow spider is not uncommon in Berkshire, Hampshire, South Bucks, South Oxfordshire, West London & Surrey where it has been found for over 100 years. It is suspected to have arrived in Torquay as a stowaway in a crate of bananas from the Canary Islands.
At PESTUK, requests for spider control are most common in autumn and early winter. This is when the spider population peaks, and as the days shorten and the weather gets colder and wetter, spiders and other insects venture inside for shelter and warmth. Treatment for spiders is fairly straightforward – we apply a residual insecticide externally around windows and doors as well as inside on walls and ceilings concentrating on the wall/ﬂoor and wall/ceiling junctions.
Preparation Prior To Treatment
When we treat we apply a residual insecticide to around windows (including sills), wall/floor junction, and ceiling/wall junction so if these areas are clear of furniture and other objects but more importantly they are clean and dust-free prior to treatment. Removing creepers and vegetation from external walls make a difference as this removes spiders’ shelter.
The rooms that have the spiders will be treated with one (or both ) of the following insecticide sprays: Effect Microtech CS’* which contains Permethrin, HSE Number 6287 and made by Sorex or K-Othrine WG250, HSE Number 5390 which contains deltamethrin 25%. These insecticides are the most modern insecticide available. The insecticide lasts for up to 3 months and the spiders absorb the insecticide as they walk over it and then die.
What Do I Do Afterwards?
After treatment, do not let domestic animals walk on treated surfaces until dry and if bare skin comes into contact whilst wet then wash. Do not vacuum the carpeted areas that have been treated for at least two weeks or longer if the room(s) are at low temperature.
As ‘new’ spiders will constantly be entering the house complete eradication is not usually possible but the treatment will drastically reduce numbers. In some cases one spray should be sufficient to deal with the problem but often the premises will need treating at least twice. Any insecticide treatments will only work on clean surfaces.

Spiders – General Information
Spiders are very successful invertebrates, occurring all over the world in many different habitats including meadows, hill, wood and buildings. They are not insects but Arachinida.
Spiders lay eggs that hatch into miniature spiders and then grow (after shedding their skins several times) into adults. The female spider in all species is larger and heavier than the male. Many have acute vision, especially the ‘Hunting’ spiders that stalk their prey.
All spiders are capable of injecting poison from their fangs into their prey. Very few spiders in England can puncture human skin. The web is spun from glands at the tail of the abdomen. All spiders are capable of spinning webs, even the new ones that don’t use webs to catch their prey. Spiders are very clean and spend hours grooming and cleaning.
Occasionally foreign spiders can be imported from hotter countries. These can kill, depending on the species.
