10 common spiders found in and around Britain’s homes — but are they really all harmless?

As we enter spider mating season, we look at some of the eight-legged creatures you might bump into in UK homes — and whether it’s worth running for the hills

Arachnophobes, look away now.

With the spider mating season upon us, the creepy crawlies will leave their webs and venture indoors to find a partner.

And here’s a fact to make your skin crawl: there are over 650 different species of spiders in the UK — and all of them bite.

But, luckily for us, only 12 of these species have enough venom that can cause harm to a human.

We’ve put together a list of 10 of the most common spiders you’re likely to find around the house in the coming months, and most importantly — whether they’ll cause you any danger .

So keep your eyes peeled and a glass at the ready as you find out which spiders are friends are which are definitely foe .

1. Missing sector orb web spider

Also known as Zygiella x-notata, this spider is named because it spins an orb web with one full sector missing.

With a size of up to 15mm, this arachnid is relatively small and is common around Britain’s houses and gardens.

The spider, which is not harmful to humans, can be distinguished by its pale body and legs, with silvery-grey markings on its abdomen.

Usually seen indoors in the autumn and winter months, this spider prefers warmth and is most common in areas around Leicestershire and Rutland.

How big are they? Up to 15mm

Are they harmful? No, not at all

2. Giant house spider

Measuring a size of 120mm, this critter is most common in the autumn months when the males leave their webs in search of females.

Often the spider you’re likely to find in the bath, they can run extremely fast, but only for a limited length of time before they have to stop to recover from their exhaustion.

These large spiders build sheet like webs and may be found in garages, sheds, attics and cavity walls where they are less likely to be disturbed.

Giant house spiders do possess a potent venom and can bite, but they do not usually pose a threat to humans.

How big are they? Big — 120mm

Are they harmful? Potentially, yes — but they’re not at all aggressive

3. Daddy long legs spider

Unlike the hairy giant house spiders, these creepy crawlies have small grey bodies and long, thin legs.

Although they can vary in size, the Pholcus phalangioides (to give them their scientific name) can potentially measure up to 45mm.

Urban myths exist that suggest the daddy long legs spider contains the most potent venom but that their fangs aren’t strong enough to penetrate human skin.

Reports on research into this theory suggests that the spiders can bite — but the venom will only deliver a brief mild burning sensation — if anything at all.

How big are they? Up to 45mm

Are they harmful? No, not really

4. Lace web spider

Usually found on outdoor walls and fencing, these spiders will retreat inside in the autumn months to find a mate.

Heavy rainfall can also force these spiders into the house, usually because they have been flooded out of their own home.

They generally grow to a size of around 20mm and are brown with yellow markings on the abdomen.

Be on your guard when you see one of these spiders, as they have been known to bite people in recent years.

Bites are reported to be painful but the symptoms usually just consist of localised swelling for around 12 hours.

How big are they? 20mm

Are they harmful? Yes — if they bite, you’ll know about it

5. Zebra jumping spider

These eight-legged creatures are small, reaching a size of just 8mm.

Recognisable from their distinctive white and black markings, the move in a jerky ‘stop, start’ motion.

These spiders are usually seen from spring through to autumn and can be found on external walls, as well as indoors where they will enter through open doors and windows.

They are more likely to flee from humans than attack them, but they can bite — although the venom is not considered medically threatening.

How big are they? Small — just 8mm

Are they harmful? No

6. False widow spider

The species, also known as Steatoda nobilis, usually has an overall size of 20mm and is characterised by a dark brown colour and a bulbous abdomen.

Adult female false widow spiders are known to have bitten humans, although they are not usually aggressive and attacks on people are rare and there are no reported UK deaths.

Symptoms of a bite can range from a numb sensation to severe swelling and discomfort.

In serious cases there can be various levels of burning or chest pains, which will depend on the amount of venom injected.

How big are they? 20mm

Are they harmful? In a word, yes

7. Cardinal spider

The cardinal spider is the largest spider in the UK, growing to an overall length of 14cm in some cases.

Also known as Tegenaria parietina, it is known as the cardinal spider in Britain because of the legend that Cardinal Thomas Woolsey was terrified by this species at Hampton Court back in the 16th century.

Although they are mainly thought to be harmless to humans, these arachnids get a bad reputation because of their huge size, incredible speed and their nocturnal habits.

Bites from these spiders are rare, and painless.

How big are they? Very — 14cm

Are they harmful? No, they look much scarier than they actually are


8. Money spider

From the Britain’s biggest to the smallest, money spiders grow no more than 5mm long, with their leg span just 2mm.

They get their name from an old superstition that if one got stuck in your hair, it would bring you good luck and increased wealth.

The money spider weaves hammock shaped webs and bites its prey to paralyse it — before wrapping it in silk and eating it.

The fangs on this spider are not anywhere near big enough to penetrate human skin.

How big are they? Tiny — 2mm

Are they harmful? No, not at all

9. Tube web spider

As you might expect, this spider is aptly named because of the tube-shaped web it spins to catch its prey.

They are often found in cracks in buildings which they will cover with silk lines while they wait in the entrance.

Originally a species from the Mediterranean regions, it can now be found in British towns including Bristol, Cornwall, Gloucester, Dover, Southampton and Sheffield, amongst others.

This spider does bite and the pain has been compared to a deep injection with the sensation lasting for several hours. Despite this, the bites do not appear to have any lasting effects.

How big are they? Up to 22mm

Are they harmful? Kind of — their bite might hurt, but the pain won’t last

10. Cupboard spiders

Closely related to the false black widow, the Steatoda grossa is often mistaken because of its dark colour and similarly bulbous abdomen.

It usually grows to approximately 10mm in length and its appearance can vary slightly from purple to brown to black.

The female can lay egg sacs at least three times a year which typically contain between 40 — 100 eggs.

They have been known to bite humans, but are not usually agressive.

Although injuries are minor, symptoms can include blistering and generally feeling unwell — which can last a couple of days.

How big are they? Up to 12mm

Are they harmful? A bit — they don’t bite often, but when they do it hurts


8 British spiders you’re likely to find at home this autumn

From daddy long legs, to money spiders.

During the colder months, British spiders will often enter our homes in search of somewhere warm to hide.

Most British spiders found in UK homes are harmless to humans, but lots of people are scared of them nonetheless. Whether it’s in the corner of our living room, in the bath or hanging quietly from the ceiling, these are the eight most common UK spiders you’re likely to spot.

Keep an eye open for these during autumn and winter.

1. Daddy Long Legs

One of the most common spiders found in UK homes is the Daddy Long Leg. Commonly also known as Cellar Spiders, the thin, spindly spiders have extremely long legs and are often found in corners of the home, particularly during late summer. During the day, this species will stay incredibly still, however, when they are disturbed, they will vibrate on their web to scare away any attackers.

2. False Widow Spider

While these spiders aren’t usually dangerous to humans, if they get caught in your clothing they might give you a little nip on the skin. These bites don’t cause much irritation, but it’s always advised to head to your local GP if irritation continues over a prolonged period of time. Most False Widows are a brownish colour with white markings on their back. When the weather cools down, you may notice the eight-legged creatures coming into your home to keep warm.

3. Giant House Spider

The Giant House Spider is one of the fastest spiders around, and can impressively run up to half a metre per second. It can be identified by its large, brown body and will commonly be found in UK homes during autumn. Places to spot them include behind the fireplace, in the bath or under the sofa.

4. Lace Web Spider

The Lace Web Spider is usually around four to 15mm long and can be spotted living in the holes of walls and bark. These are very common and widespread around the UK, so don’t be surprised if you find them around your home during autumn and winter, particularly after it has rained. Their web is made from a fine silk (which is where their name comes from) and has a wooly texture.

5. Zebra Spider

The Zebra Spider — or the Jumping Spider — can be identified by its black and white body. This species may be smaller in size compared to others, but they can move very fast (especially when they feel they are being attacked). During April and October is when you are most likely to see this spider.

6. Cardinal Spider

One of the largest spiders in the UK is the Cardinal Spider — which can grow up to 14cm in size. You’ll be able to spot this species by its reddish brown body and find it living mostly in walls of buildings. They’re not prone to bite humans, but have been known to react with a bite if they feel threatened.

7. Money Spider

The Money Spider is a family of very small spiders, which are also often known as Sheet Weavers. They are often spotted close to ground level on garden plants, in long grass or around plant pots outside. Around five millimetres in length, they are small compared to others found in the home. You’ll be able to identify the spider by its glossy brown body.

8. Orb Weber Spider

Orb Weber spiders are found between July and October, making webs in gardens around the country (and helping to keep the flies out). They are eight millimetres long and get their name from the large orb-shaped web they spin.
