In the UK many news articles can be found about False widow spiders. They would bite people, kill animals and they even infested a school which was then fumigated (2013).
However they are very widely spread already (originally they come from the Canary islands).
In recent years I have seen them often inside the house here in Ireland. At one time I had nearly 50 of them indoors.
They made various cobwebs but did not bother me at all.
It is very easy to handle a steatoda nobilis spider and they do not bite at all.
Once you picked it up, you can make it drop down very easily as well.
They are not likely to bite because they do not rest or make a web inside clothing (like for instance brown recluse).
What they like most is inside kitchen cupboards, in corners under the ceiling, and also on window sills.
As soon as these spiders make a cobweb (indoors), they will stay there, sometimes for months. They also wander around sometimes.
I had one of these spiders living in a cardboard box inside a kitchen drawer for nearly two years!

information about false widow spider
Steatoda nobilis and Steatoda grossa are similar, but Nobilis normally has reddish legs. Grossa is also known as "cupboard spider":
S. grossa, often known as the cupboard spider. A dark-colored spider which resembles specimens of Latrodectus, though without the characteristic bright marks found on most widow spiders. This spider is known to occasionally prey on true widows. Bites by S. grossa have been known to produce symptoms similar to (but far less severe than) the bites of true widows. Originally from Europe, but now found worldwide.
S. nobilis. This spider, a native of the Canary Islands, has since been introduced into the United Kingdom and across Europe. Sensationalist news reports in the UK have focused on its reportedly-painful bite, including a case of man needing treatment for symptoms of heart seizure.
S. paykulliana, another spider which is often confused with Latrodectus. This one is generally found in the range of Latrodectus tredecimguttatus and is frequently confused with it. Has a medically significant (but not serious) bite.
