Thousands of lusty spiders invade British homes as mating season begins

Sex-addicted spiders will invade people’s homes in the coming weeks as the mating season begins.

The arachnids hide in people’s homes all the time, but they usually stay in their webs and don’t move much.

But during the fall, males go out hunting for a mate, meaning you’re likely to see a lot more of them in the coming weeks.

The spider season usually starts in the first two weeks of September and ends in the first week of October.

You may not notice it, but small houses in the UK can often contain up to 40 spiders.

The number can be even higher for larger Victorian properties with lots of cracks and crevices to hide in.

A reader of recalled a recent horrific discovery, saying: ‘This huge furry black spider – horns, fangs, the works – was seen on the doorstep of my bedroom where the balcony door opens into the room.

“I closed the balcony doors and windows hoping it would stay out.

“When I woke up the next morning, the spider was sitting there on the curtains in my bedroom.

“I was shocked, of course, scooped up all the curtains, threw them out the open window and closed it tightly. I didn’t bring them in until I was sure the spider had moved on.’

She thought everything was fine until another unwanted visitor (pictured below) showed up the next day, twice the size of the first in terms of wingspan, much longer legs and very visible hair.

The reader added: ‘While much less bulky and generally less terrifying, it was still an unwelcome visitor to my home. I walked away and left him, because I couldn’t bear to touch it.’

If you need some tips on how to keep them at bay, one of the best things you can do is keep your windows and doors closed.

Spiders also hate essential oils like lavender and peppermint, which is another way to keep them from invading your home.

They are also thought to hate citrus and vinegar, and cleaning your house regularly can help keep them away too.

Expert Richard Jones previously told the BBC: ‘The ones we see scurrying around the house are usually the male house spiders.

“The ones you see running across the carpet in front of you drive you crazy, usually it’ll be a man out on some amorous chase.

“I think even the cleanest, smallest house will have about 20 to 40 spiders. Old Victorian houses like mine – with lots of little cracks and crevices and places for things to get in – I wouldn’t be surprised if we’re well into the four digits.”

There are some 650 species of spiders in the UK but only 12 are really harmful to humans.

The noble false widow spider, or ‘Steatoda nobilis’, has become a common species in urban areas of the United Kingdom.

They can grow to about an inch in length and damage from their bites can range from mild to debilitating pain or a mile to intense swelling.

However, there has never been a confirmed death caused by a false widow in the UK. In Aldershot in 2014, a 60-year-old woman was bitten by one of the creepy crawlies and was taken to hospital.

She had to have a finger amputated, started hallucinating after surgery and died a week later, but even then it has not been confirmed whether the spider was responsible for her death.

Nottingham Trent University ecologist Dr Chris Terrell-Nield says the most common spider to enter people’s homes is the house spider – one of the largest in Britain.

He previously told NottinghamshireLive: ‘The males are up to 10cm across the leg span and can be the size of your hand – that’s the highest range, but it can be two-thirds that size. The size depends on how much they have eaten.

“They’re not dangerous, but they can give you a bite. They have biting teeth. These things are breeding and starting their lifespan in the spring.

‘At this time of year, August and September, the male spiders tend to mate and wander and look for females. When they find them, they mate and lay eggs and usually the male dies.’
