Wolf spiders are venomous, not poisonous. Their venom is used to subdue prey but is generally harmless to humans. A bite from a wolf spider may cause some pain, swelling, redness, and itching, but it is not medically significant or lethal for most people. Serious reactions are rare and usually related to allergies or secondary infections. Medical attention is typically not required unless there is an unusual allergic reaction or the bite becomes infected.
Distinction Between Venomous and Poisonous
- Venomous means the spider injects venom through a bite or sting.
- Poisonous means harmful toxins are absorbed or ingested.
Wolf spiders are venomous; they do not pose a poisoning risk from contact alone.
Symptoms and Effects of Wolf Spider Bites
- Mild pain and swelling at the bite site.
- Redness and itching sometimes occur.
- Severe pain is uncommon, but possible.
- Necrotic ulcers have not been shown to result from wolf spider bites.
- Rare systemic symptoms like nausea or headache can occur but are uncommon.
Safety and Precautions
- Wolf spiders are not aggressive and bite mostly in self-defense.
- Bites usually occur if the spider is provoked or accidentally handled.
- Medical care is rarely necessary unless allergic reactions occur.
In summary, wolf spiders are venomous with bites that may cause mild reactions in humans but are not considered dangerous or poisonous.
