Do Huntsman Spiders Bite? Understanding the Risks and How to Identify Them

Huntsman spiders are among the most recognisable spiders in New Zealand, thanks to their large size and long, crab-like legs. Despite their intimidating appearance, many questions remain about their behaviour and whether or not they pose a danger to humans. If you’ve ever asked yourself, “Do Huntsman spiders bite?” or “Are Huntsman spiders dangerous?”, you’re not alone.

This blog provides accurate, up-to-date information to help you understand Huntsman spider behaviour, how to safely identify them, and what to do if you encounter one in your home.

What Is a Huntsman Spider?

Huntsman spiders belong to the Sparassidae family and are known for their speed and ability to climb walls and ceilings. While they may look intimidating, they are generally shy and prefer to avoid human contact. Their name comes from their hunting style—they don’t build webs to catch prey, but instead, actively hunt insects, making them a natural form of pest control.

In New Zealand, huntsman spiders are not native, but introduced species have adapted well to local environments, especially in warmer northern regions.

How to Identify a Huntsman Spider

Correct Huntsman spider identification is key to understanding whether you’re dealing with a harmless visitor or a potential health concern. Here are some traits to help you identify one:

• Size: Huntsman spiders can have a leg span of up to 15 cm.
• Color: They are typically brown or grey, sometimes with darker markings.
• Leg Shape: Their long legs are slightly twisted forward, giving them a crab-like stance.
• Habitat: Commonly found under bark, in sheds, garages, or behind furniture.
• Movement: They are quick movers and may startle you when they dash across a surface.

Do Huntsman Spiders Bite?

Yes, Huntsman spiders can bite, but it is extremely rare and usually only occurs if the spider is provoked or threatened.

Are Huntsman spiders dangerous? Not typically. Their bite may cause:

• Localised pain
• Minor swelling or redness
• In rare cases, mild nausea or headache

Huntsman spider bites are not venomous to humans and are generally considered low-risk. Most bites are defensive rather than aggressive, and Huntsman spiders usually retreat when approached.

What Should I Do If Bitten?

Their appearance indoors is usually accidental, and they pose no long-term threat to your home.
