HUGE SPIDERS will be invading your home soon as mating season begins — but which creepy crawlies should you expect to catch a glimpse of?

It is the time of year when eight-legged pests begin to invade your home. While it is a customary event each year as the autumnal season arrives, almost one in five Britons across the UK suffering from arachnophobia struggle with this time of year. Spiders begin to take over people’s homes from September through until October while they seek out a dry place to mate, which means by the first week in October you should start to see them less often. But what types of spiders could you see in your home?
The Giant house spider can reach up to 120mm wide and is most commonly found in sheds and gardens and cavity walls where they are less likely to be disturbed.
However, as mating season begins they move inside to find a dry place to mate.
Often the Giant house spider is one that you will find in your bath.
They can run very quickly, but only for a short amount of time before they need a break to recover from their exhaustion.
This breed of spider is renowned for making large webs which can last for years.
Giant house spiders do possess potent venom and can bite, but they do not usually pose a threat to humans.
Cellar spiders, or Daddy Long Legs, are large and off-putting as they can grow up to 45mm.
Unlike the hairy giant house spiders, these critters have small grey bodies and long, thin legs.
Urban myths exist which suggest the daddy longlegs spider contains the most potent venom, but that their fangs are not strong enough to pierce human skin.
Reports suggest that cellar spiders can bite, but the venom only delivers a very brief and mild, burning sensation.
Money spiders are Britain’s smallest spider, growing no more than 5m long with their leg span recorded as 2mm.
Their name comes from an old superstition that if one got stuck in your hair, it would bring you good luck and increased wealth.
The money spider often hangs upside down under a sheet web and their webs can normally be spotted in bushes or shrubs.
During mating season, they are often seen in the corners of homes.
The money spider weaves hammock shaped webs and bites its prey to paralyse it — before wrapping it in silk and eating it.
They are harmless to humans as their fangs are not anywhere near big enough to break human skin.
Lace web spider
Lace web spiders are usually found on outdoor walls and fencing, these spiders will retreat inside in the autumn months to find a mate.
People are known to mistake these creatures for false widow spiders, but in fact, they are different.
They have long bodies, as well as shorter and thicker legs and are known for heading inside homes during the autumn to mate, especially if there has been a lot of rain causing them to lose their home.
Generally, they grow to a size of around 20mm and are brown with yellow markings of the abdomen.
In recent years, these spiders have been known to bite people and the reports have said the bites are painful, but the symptoms usually consist of localised swelling for around 12 hours.
False widow spider
The false widow spider, which grows to around 20mm, is nocturnal and therefore generally spends the daytime sleeping.
They like dry and warm environments and do not like being disturbed which is often what attracts them to people’s homes.
Even though they are more likely to be spotted outside, they also like to perch themselves under toilets, fridges and washing machines.
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.
If bitten, symptoms include a numb sensation to severe swelling and discomfort.
In more serious cases, there can be various levels of burning or chest pains, which will depend on the amount of venom injected.

Spider season is here and West Midlands residents will likely see a rise in eight-legged friends in the weeks to come.
The chilly weather will see more and more male spiders leave their webs in search of females, with households across the region set to be home to plenty of arachnids.
