Australians are being warned that recent hot, wet weather has created perfect conditions for deadly funnel-web spiders to thrive.

The Australian Reptile Park posted the warning to its Facebook page this week.

"Because of the recent rains and now the hot days we're now experiencing, funnel-web spiders will start to move around; in particular, male funnel-webs as they start to venture looking for a female funnel-web spider to mate with," Dan Rumsey, a zookeeper at the park, said in a video accompanying the post.

A funnel-web spider is pictured at the Australian Reptile Park January 23, 2006 in Sydney, Australia. The Funnel Web is one of Australia's deadliest animals, with a venom that is packed with at least 40 different toxic proteins. A bite from a Funnel Web causes massive electrical over-load in the body's nervous system. Finally, fatalities occur from either heart attack or a  pulmonary oedema, where the capillaries around the lungs begin to leak fluid and the patient effectively drowns. Death can come as quickly as two hours after a bite if no medical treatment is sought. Due to advances in anti-venom, there has been no death from a Funnel Web bite in Australia since 1980. Australia is home to some of the most deadly and poisonous animals on earth.  (Photo by Ian Waldie/Getty Images)

Severe thunderstorms over the weekend caused flash flooding and hail in parts of New South Wales and Queensland.

The rainfall combined with high summer temperatures have created ideal tropical conditions in which funnel-web spiders thrive, Australian Reptile Park keeper Jake Meney told the Australian Broadcasting Corp.

Rumsey said, "Funnel-web spiders are potentially one of the most dangerous spiders on the planet, in terms of a bite towards humans, and we have to treat it very seriously."

No one has died from a funnel-web spider bite since the 1980s, in part because of the reptile park's antivenom program.

In the Facebook video, Rumsey encouraged adults to catch male funnel-web spiders and bring them to the park, where they are milked for the raw venom.

He said the ground-dwelling spiders are easy to catch. They can't climb smooth surfaces like plastic or glass. Rumsey suggested using a metal spoon or plastic ruler to guide the spider into a glass jar or plastic cup or container.

Of the 35 species of funnel-web spiders, the Sydney funnel web — Atrax robustus is the deadliest, according to Australian Geographic.

They tend to live in rainforests and wet scrub forests, but they can venture into private gardens. They like dark spaces, so they have been known to crawl into shoes and laundry baskets left outside.
