The Urban Pantheist

Hi, i was hoping somebody here would be able to help me. I just spotted i bright red spider running accross the bathroom door, and then onto the floor. I paniced and immediately stamped on it. Having looked about on the internet it looks like the woodlouse spider is the closest description to what i saw - I've also recently saw the odd woodlouse in the bathroom, so this would make sense. I have a 4 month old baby living in the house, and am now worried about her safety. Is there likely to be more of these spiders? Is there a way to get rid of them, and will my daughter be safe? Thanks in advance for any help :)
