Black Shiny Spiders

[theboyrob]

At my parents house in France in the end wall theres probably around 30-40 small black shiny spiders lurking in the cracks.

I am unsure to whether these could be a problem. It seems to me having so many in such a small area isn't good, especially with them sounding like possible black widows!

Has anyone any experience with spiders?

my dads out there at the moment and back on the weekend, will try and get him to get a picture.

Just seems wierd hows there's so many all together, must be 40 at least on a 15ft long end house wall.
