A stark warning has been issued as Britain's 'most dangerous spider' with an 'unbearable' bite is about to invade homes across the UK.
False widow spiders are set to appear in greater numbers as spider mating season is set to begin later on in August.
This is prompting experts to urge people to keep windows closed both day and night.
The venomous animal delivers a bite that, although not lethal, can cause swelling, painful burns and even fever.
It is the largest of the three false widow species commonly found near homes.
