That would depend on the type of spider. Most are harmless, but a few can be lethal or cause severe skin lesions. If you are bitten try and get someone to catch the spider and take it with you to hospital so that it can be identified and your treatment tailored to that particular spider's venom.
No, they are not poisonous to humans. Their bite is non-lethal, but it will cause some pain.
