The site of a wolf spider bite is somewhat swollen and red. Upon closer inspection, puncture wounds or a tear mark are visible from the fangs. Rarely, some necrosis of the skin occurs around the bite. Necrotic tissue is discolored, soft and painful, and it emits a foul odor.
Once bitten by a wolf spider, there are some telltale symptoms. The initial bite is painful. In addition to the wound site becoming red and swollen, there may also be swelling in the lymph glands for several days following the bite. According to the Fumapest Group, a wolf spider bite does contain venom, but it is not considered to be overtly dangerous or lethal to humans.
