need to know more please
i have spiders like this in my house in iowa!! never seen them any where till i did research and found your pics do u know if they r harmful i have been bit by one and had a slight reaction ie itching small bump red then lil pain but lasted almost a week,i dont know it my head aches had anything to do with the bite at the time? thank you for any thing you can tell me about these spiders.

 
Are you sure?
These spiders are only 2 mm. I don't think it's even possible for them to bite through human skin. As the Balabans mentioned on your other post you only need to watch out for widows & recluse spiders. Any other spider bite (which are extremely rare) might cause a reaction like a bee sting... harmless.

From Rod Crawford...
Definitely not Erigone - they have teeth around the edge of the
carapace. Microscopic examination needed for positive ID. One
possibility would be Pelecopsis sculpta, but that's not something I'd
really expect on a windowsill (they're moss spiders).

Rod looked at this again and says it's "probably" Entelecara acuminata
