Spider bites can be from a range of appearances. Some can be VERY large or almost miniscule. Spider bites can also be tremendously itchy but nothing to worry about if you rub hydrogen peroxide to kill all the bacterious venom still left in the bite. Also, if itching continues immediately rub benodryl on the bite (rubbing cream benodryl, not the pill). If itching persists, seek help from a doctor. www.ismp.org
