It’s that time of year once again.

We’re waving goodbye August and saying hello to September, with the record-high temperatures of the summer already looking like a thing of the past and autumn on the horizon – and that, of course, unfortunately means it’s spider season.

According to experts, the giant “hand-sized” house spider is gearing up to rear it’s ugly head in households across the UK as it searches for somewhere warm to escape the harsh outdoor conditions.

Oh, and it’s also looking for a mate too and has been described as “sex-crazed”.

In what is bound to be bad news for Greater Manchester’s arachnophobes, it’s been confirmed that around the first or second week in September, there’ll be a rise in the number of large, male spiders wandering through homes, and females will tend to stay in places like underneath windowsills and webs. 


Of the 650 species of spider in the UK, most are too small to be able to bite, but the Tegenaria Domestica and Eratigena Atrica – also known as the giant house spider – are “generally quite large”, and according to The Wildlife Trusts, can be identified by its dark, hairy body and long legs.

It typically has a leg span of up to 7.5cm, and can run up to half a metre per second.

Professor Adam Hart – Entomologist at the University of Gloucestershire – said that we don’t really need to worry though as they are relatively “harmless”.

He also revealed that peak time for spotting spiders indoors is around 7:35pm.

He continued: “There’s nearly always a way to get in the house, they can also come in through things like towels that are left outside. Keeping your house tidy and keeping clothes off the floor may reduce places for them to hide, but it’s very difficult to keep them out.”

Whilst he did state that this is the typical time for spider mating season, he added that it won’t stick around for long and should come to end at the start of October.

So, what are some of the best ways to deter spiders from your home then? Lucy Askew – spokesperson for Hillary’s – has shared her six top tips on how to keep spiders at bay this autumn/winter:

  1. Put conkers in the corners of your rooms.
  2. Create your own natural spider deterrents using citrus juice, essential oils, and vinegar.
  3. Seal the cracks in your home – especially near windows.
  4. Keep your windows closed at night.
  5. Maintain / keep on top of your cleaning routine.
  6. Turn off your outside lights.
