The Giant Huntsman Spider (Heteropoda maxima) is the largest spider by leg span, reaching up to 12 inches (30 cm). Found in caves in Laos, it has gained a reputation for its massive size and speed. Many people wonder: Does the Giant Huntsman Spider bite? Is it venomous or dangerous? Based on what I know about Huntsman spiders, here’s the truth about their bite, symptoms, and interesting facts.
Does the Giant Huntsman Spider Bite Humans?
Yes, the Giant Huntsman can bite, but it rarely does. It is not aggressive and prefers to run away when threatened. However, a bite can happen if:
- It feels trapped or cornered.
- It is accidentally touched (e.g., reaching into a dark space where it’s hiding).
- Someone tries to handle it roughly.
Despite its intimidating size, this spider is not considered dangerous to humans.

Symptoms of a Giant Huntsman Spider Bite
While the bite may be painful, it is not lethal. Here’s what to expect:
Mild Symptoms (Most Common)
- A sharp sting at the bite site
- Redness and slight swelling
- Mild pain that fades within a few hours
- Itching around the bite
Moderate Symptoms (Less Common)
- Increased swelling in the surrounding area
- A burning sensation for a few hours
- Minor numbness or tingling near the bite

Rare but Possible Severe Reactions
- Allergic reaction (rash, dizziness, difficulty breathing)
- Secondary infection if the wound is not cleaned properly
Unlike venomous spiders such as the Black Widow or Brown Recluse, the Giant Huntsman’s venom is not medically significant.
