can someone please id this spider for me I found it in my shed which gets used by my family, should I be concerned for my family? do I need to get someone in to deal with them?
This is Steatoda nobilis, the noble false widow. I would certainly take any you might find inside the house & throw them outside. Regarding the shed...you could get someone in to remove them, but if they are established in your area, you might find that, eventually they are replaced?
Females tend to stay close to a hiding place/cover & don't wander around much, rarely leaving their web. It would be wise to be aware of them in order to avoid mishaps in the future, but they are not aggressive - bites are very rare and usually the result of the spider being crushed against the skin. The venom is not dangerous to healthy humans, those with reduced immunity & allergies should excercise caution, any signs of infection (possible with any bite/sting/cut) should be treated sooner, rather than later. Females like a degree of space between each other, so it's not like having a wasps nest in the shed, there won't be hundreds of individuals in a nest, or zooming back & forth.
Ultimately, you have to do what you feel is best for you & your family, I certainly wouldn't like to be bitten (or to hear of anyone else receiving a bite), but they are well established where I live & most of us have some around the exterior of our home (I have them inside & out) & in sheds/garages etc., they don't really pose a significant risk. They are certainly not deadly, as reported in the press.
I did think it was the false widow but wasnt sure. I now feel that I have to tell the local paper or something because these spiders are not suposed to be in our area. I live in Peterhead, Aberdeenshire in the north east of Scotland. I also have a small dog which likes to eat insects so Im a bit concerned for it too.
Thank you very much for your info it is really helpfull and kind of you. Im a big woose when it comes to spiders so atleast now I know what I'm dealing with.
Steatoda nobilis has been spotted in Aberdeen before, possibly better to contact the British Arachnological Society & if you feel it necessary, take your captive down to the local GP practice, so that they are aware of their presence (there is no antivenom required, or necessary, "treatment" is only likely to be antibiotics if a bite becomes infected).
