Numbers of Britain’s deadliest spider, the False Widow, are thought to be on the rise. Last year the venomous spiders caused havoc on the UK with several schools being forced to temporarily close due to infestations. Experts say the insects are not normally aggressive towards humans and bites are rare, but if the spiders are caught in clothing, prodded or squashed they may give you a nasty nip.

What to do if the False Widow spider bites you

A False Widow spider’s bite usually only cause minor irritation.

However, some stings can be painful and trigger a serious allergic reaction.

The spider’s venom can cause localised pain, minor swelling and, in extreme cases, nausea.

When the insect bites, it releases saliva that can cause the skin around the bite to become red, swollen and itchy.

If you are bitten by the spider the first thing to do is wash the area with soap and water.

A bite spray or antiseptic cream will also help to prevent infection.

But if there’s a lot of swelling and blistering or if there’s pus you could have an infection and it could be wise to seek medical help.

What is the False Widow spider?

The False Widow spider is often mistaken for its much more dangerous distant cousin, the Black Widow.

The noble false widow is the most venomous of the three types of false widow species found in and around British homes.

It is believed that the spider was first imported to Britain in bunches of bananas from its native homelands of Madeira and the Canary Islands.

The first sighting of a noble false widow was in 1879 in Torquay but the species has since spread across southern England.
