Huntsman spider

Huntsman spiders are a group of large, fast-moving spiders in the family Sparassidae, known for hunting prey rather than catching it in webs.

Updated September 12, 20261 min readCited sources

Huntsman spiders are large, fast-moving arachnids in the family Sparassidae that actively hunt prey instead of building webs. They are common in warm regions worldwide and are often found in homes, sheds, and gardens.

What it is

Huntsman spiders belong to the family Sparassidae. They are typically large, flat spiders with long legs that extend sideways, a shape that helps them fit into narrow spaces. Unlike web-building spiders, they rely on speed and agility to catch insects and other small animals.

Where they live

These spiders thrive in warm climates across Australia, Asia, Africa, and the Americas. They shelter under tree bark, in rock crevices, under logs, in foliage, and inside human structures such as homes, garages, and sheds. In Canada, they are rarely encountered outdoors but may appear in imported goods, greenhouses, or while travelling.

Human interactions

Huntsman spiders are generally harmless and prefer to flee when disturbed. Bites are uncommon and usually cause only local pain, redness, or swelling. Some species may produce more noticeable symptoms like nausea, but serious effects are rare. To remove one indoors, gently trap it in a container and release it outside.

In short

  • Huntsman spiders are active hunters, not web-builders.
  • They are large, fast, and found in warm regions globally.
  • Most species are not dangerous to humans; bites are mild.
  • In Canada, they are uncommon and usually linked to imports or travel.
Canadian angle

Huntsman spiders are not commonly associated with Canada because they prefer warm climates; Canadian readers are more likely to encounter them in imported goods, greenhouses, or while travelling abroad.

Quick questions

Are huntsman spiders dangerous?
They are generally not considered dangerous. Most bites cause only local pain or swelling, though some species can cause more pronounced symptoms.
How big is a huntsman spider?
They are large spiders with very long legs; leg span varies by species, with some reaching tens of centimetres.
How do you get rid of huntsman spiders?
Seal cracks and gaps, use flyscreens, and reduce clutter. If one is indoors, trap it gently in a container and release it outside.
