We have loads of False widows here in Worthing on the south coast.
They can bite and my Mrs has been twice but she hardly reacted at all, a tiny bit pf swelling but nothing major, I have gently handled them but normally move the ones that are inside with some paper, they are not overly aggressive and don’t want to waste their venom.
A work colleague’s father was bittern and he reacted badly and had to go to hospital but that is no really any different to the fact some people react badly to wasp stings etc.
Leave them be and you will be fine, wasps on the other hand need torturing before death as are evil sadistic sting happy monster !!!
