Forest Wolf Spider
This Forest Wolf Spider is rather large, male 3/8", female
3/8 - 1/2". This Wolf Spider hides by day, hunts at night.
They are superb hunters, both day and night. The bite causes
intense itching and may progress to (necrotic arachnidism)
local tissue death. The venom is cytotoxic and generalized
destruction of red blood cells are not usually seen. Treatment
is the same as for the brown recluse.
Outdoor Treatment for Forest Wolf Spider
Elevation of the extremity is important.
Cool compresses rather than warm are important. Tetanus update
should be provided. Keep the bite site clean until reaching
your health care provider for further treatment. Antihistamines
may help control itching but will not change the wound. Sometimes
surgical excision of the wound site needs to occur.
A series of 515 cases of confirmed Lycosa
bites in Brazil showed that most occur between the hours
of 6 AM and 6 PM, at a fairly consistent rate year-round.
The most common bite sites were feet (40%) and hands (39%).
The most common signs and symptoms were all local, with
pain in 83%, swelling in 19%, and erythema in 14%. No local
necrosis was described.
In the United States five cases of Lycosidae bites have
been documented. One resulted in skin necrosis at the bite
site, probably from the combined results of envenomation
