The difference between Funnel Web Spiders and trap door spiders

Both the Sydney Funnel web spider and trap door spiders are classified as ground spiders which means unlike other spiders they do not create webs.

Ground Spiders are found dwelling underneath bark, rocks, and other objects on the ground and will only leave the burrows when they need to hunt for food.

All ground spiders are nocturnal hunters and hide during the day, however, there have been reports that ground spiders have ventured out to find a mate or to move to higher ground during heavy rain and floods.

The funnel web spider is considered the deadliest spider in Australia, whilst the trapdoor spiders venom is not fatal to humans and only causes minor symptoms.

Are you worried about ground spiders ?



To the untrained eye, both spiders do look the same, however one is dangerous and deadly and the other is considered a low risk.
