I have recently found this spider in my block of flats that has white markings on its back. This isnt the best pic but in all honesty i was too petrified to go any closer.....besides spiders are my number 1 fear even money spiders! I reported it to a neighbour who tried to catch it but it was too fast to be caught and got away! Since finding this my neighbour has had a look around the rest of the block and has found alot more in other places all with similar markings on their backs.
The photo isn't really sharp enough to ID the spider.
Can you tell us anything about the spider's webs, what they look like?
Even if it was a false widow (I'm not saying it is, there are a few species it could be & some that are often mistaken for false widows), if you get too close it will run off to find a hiding place, it's not likely to jump from the web. It's web is its shelter & means for catching food. I have been photographing a false widow in my living room for years, the biggest problem is getting it to stay in sight long enough ;-) They are actually quite docile & shy.
Most importantly remember there aren't any truly dangerous UK spiders.
Thank you for your advice. When i was trying to photograph the spider it was gone in a blink of an eye I was shocked at how fast it had moved! it has since been hiding somewhere behind a light.it has spun 4 different webs above 4 lights on the wall. The webs are long and kind of hammock shaped if that helps at all,they have an awful lot of green fly stuck to them too. What with all the horror stories in the news of people being bitten and the fact im a big wally and run a mile from any spider its had me a little bit worried as to how likey it is one would actutally bite you, i have young children and would freak if i found one in my home. Also is there is an infestation is there any thing that could be done to have them removed?
They do mostly hide away during the day & patrol their webs from dusk onwards. Females really tend to stay put, disturbance by humans & predators is most likely reason for them to wander. Males do tend to wander more in search of females.
There are still a few other species that make similar webs, so I'd still await better confirmation.
I'm sure that someone will take your money to remove them & you are perfectly entitled to do so, given your concerns for your children. But bear in mind that they are more likely to be stung by wasps & bees, that once the spiders are removed that new individuals may repopulate the same places & that botched attempts to remove them may see displaced spiders looking for new places to set up home?
Bites usually occur by accident, maybe someone interfering with the web, or a spider getting trapped & squashed against the skin, they don't prowl around looking for people to bite, it's a rather unlikely scenario even where false widows are common. Be aware of them, certainly tip any outside should you find any inside your home, but many of us live in close quarters with them day in, day out with no issues.
