Based on the third image, that one looks very much like the false widow spider. These are the UK's most poisonous spider, so you shouldn't attempt to pick it up with bare hands if you want to move it outside. You should be careful not to get bitten. These Spiders are rapidly spreading throughout the UK from the south east and if you type false widow spider into google you can read more there.
Image 1 & 4 are the same spider I call it spidey 1 & images 2 & 3 are the same spider I call spidey 2! They are both very similar in size & appearance but spidey 1 is always hanging upside down & doesn't stray far from the safety of the nook it has found itself. As I am a complete arachnophobe these are the best pictures I can offer & I kinda expected that it was going to be a false widow if I'm honest. I do not plan to get any closer to either of these spiders but I am however concerned about what I am reading about them as I have a 3 month old baby & an autistic 4 year old who has no fear of bugs or anything really so obviously my concerns are primarily for their safety. What would be the best thing to do? Leave well alone & pray they don't enter my house (right now they are both living in my front door frame) or find someone to safely remove in order to minimise any danger to my unsuspecting children?
Thank you for your response Insectwatch
I agree with insectwatch, these are false widows (Steatoda nobilis).
They obviously concern you, so perhaps getting someone to remove them would be a good idea, for your peace of mind. However, it is likely that more may eventually turn up, if they are established in your area. As the winter draws closer, they are less likely to be replaced until next year.
They do like man-made structures (like porches, window frames/sills, exterior walls etc.), but they don't relish contact with humans. They are not aggressive. They tend to stay high off the ground & stick to their webs, close to their hiding place. They can move pretty fast when spooked and dashing back to safety.
If they have set up home in the porch, then it is unlikely that they will voluntarily leave their webs, or head indoors. They will most likely just sit the winter out, outdoors & reappear in the spring.
Despite somewhat sensationalised reports in the press, they are not deadly, nor dangerous. They are able to deliver a bite (like a wasp/bee sting), but this is very, very rare & usually if trapped in clothing & being crushed. I don't doubt that a bite is unpleasant & something to be avoided wherever possible.
Notice that many of the reports of bites occur when the victim is sleeping...I don't know about you, but I sleep with my eyes shut and can't see much! ;-) The victims then discover these spiders living in another part of their property and put 2 & 2 together, but it doesn't necessarilly add up, as the females (large bulbous abdomens) don't roam around, of their own accord. Males (smaller abdomens, about the same size as the head) do wander & it is wise to remove any that you see, however these are less conspicuous as false widows & I suspect a lot get overlooked due to looking like generic 'spiders'.
They are very well established where I live and still the vast majority of the population here are totally unaware of them, despite the fact that many of us pass within feet of them every day...I certainly do, as I have one living in my front room. She has only left her web once in the last year & that was only to steal food from a neighbouring spider's web. Whenever there is significant movement, or if I seem to be taking too much interest in her, she bolts for cover. The way I look at it, is - that as long as I know she is there, she isn't anywhere else & that destroying her web/trying to catch her is more likely to bring us into contact, especially if I fail to catch her, or if she has to wander off to find a new home.
FWIW I was a "complete arachnophobe" too, until a couple of years ago.
If the chances of the straying from their webs is unlikely then I am happy to leave them be! I'd much rather know where they are than not! Also as it seems they only come out at night I'm thinking my 4 year old is highly unlikely to actually see one. Thank you so much for your help and advice.
