Six spiders you're probably going to see in your house this September

Pest management consultant Clive Boase said: “Sightings of spiders often peak from September as males of many species reach adulthood and venture into homes in search of a mate, but we could be seeing a lot more of them than normal over the next month or two.”

But there's no need to be alarmed. Here's our guide to the six spiders you're most likely to spot.

Money spiders

Easily identified from their small bodies (5mm or less, although their legs can be quite long) and their habit of hanging upside down under a sheet web. More than 40% of Britain's spiders belong to this family, and they're not all the shiny black ones you might be thinking of.

Their webs are very often seen in shrubs or bushes, but they will also take up residence in the corners of houses, where at this time of year you can see the males doing their mating dance for the females. Totally harmless and traditionally believed to bring good luck.

Daddy Long Legs or Cellar spiders

These are big and a bit freaky looking. They are rarely found outside, and prefer to hang uspide down in their scruffy webs in the warm corners of your ceilings or cupboards. They grow to 45mm (including legs) but they're harmless and they do eat a lot of other spiders, including some house spiders (see below). So unless you really can't stand them, this one is worth leaving alone.

House Spiders

These are the biggest of Britain's spiders, with some reaching an overall size of 12cm. It's one of the only species to match a large body with large thick legs. This one, the Tegenaria duellica, is only found in the east of Dorset - in the west your house spider is the Tegenaria saeva. They spin very large webs that can last for years, often passing from generation to generation. The webs were were reportedly used as bandages in the 1700s, while the spiders themselves were once eaten alive as a cure for a fever. We don't recommend that, but they're much less scary than they look.

Lace web spiders

These are often mistaken for false widow spiders, but are longer of body, with shorter and thicker legs. This spider comes indoors in the autumn to look for a mate or if it's rained a lot and their homes have been flooded.

If you're not sure if you've got a lace weaver or a false widow, look for a web - the lace weaver's web is flat and intricate, and usually built over walls or other surfaces, with a central hole where the spider hides. They're pretty mean looking, with a total length of 2cm and quite thick legs. They do bite, but they're not aggressive and symptoms should consist of swelling for no more than 12 hours.

False Widows

This is Steatoda Nobilis, the noble false widow. It's one of three false widow species in the UK, the largest - and the one mostly likely to come into your house. It's been on the south coast for more than 150 years. The British Arachnological Society says: "Everybody in the coastal counties of Southern England has had lots of them in their house and garden for many years, whether they have been aware of this or not."

The false widow is unlikely to bite you unless you sit on it or it gets trapped in your clothes. Should you get bitten, it should be no more painful than a wasp sting, experts say - pointing out that many of those with spider bite horor stories did not see the creature that bit them.

If you don't want to take the risk, they are pretty slow moving, so they're easy to catch and remove from your house. They are mostly found outdoors but they do like to lurk under washing machines, fridges and toilets.

Other types of false widow you might see are the rabbit hutch spider - much smaller and not known to bite - and the cupboard spider, which does bite, but not often.

Zebra Jumping spiders

These tiny - 8mm- spiders are usually found in the garden but do occasionally make their way through open doors and windows at this time of year. They're harmless, but if you're not expecting it their jump might alarm you. And their mating dance is something pretty special.
