How did they they run out of venom?
Not enough funnel spiders were donated to The Australian Reptile Park's anti-venom programme, last year.
A recent heat wave also encouraged more spider activity and bites, the reptile park's general manager Tim Faulkner said.
"We have tried to catch enough spiders ourselves and we just can't."
How dangerous is it to catch a spider?
If someone is bitten by the funnel spider, the large fangs and acidic venom will make the bite painful. A major bite can lead to death within an hour if left untreated.
But the reptile park says there is a safe way to catch deadly spiders and all you need is a wooden spoon and glass jar.
"With an appropriate jar and a wooden spoon, you can flick the spider into the jar so easily," Faulkner said.
Avoid using plastic containers as spiders can bite their way out.
While Australia has a bad reputation for its long list of deadly animals, the reptile park said there have been no deaths from funnel-web spider bites since the anti-venom programme began in 1981.
How is a venom turned into an antidote?
The venom is secreted through the spider's fangs, and then collected.
The park delivers the venom to a division of a blood plasma and vaccine maker, which converts it into the life-saving antidote. The antidote is administered to those bitten by poisonous spiders.
