As if devastating wildfires and golf ball-sized hail weren’t enough — now Australia has to worry about an increase in the deadly funnel-web spiders.

The extreme weather conditions down under has sparked concerns of a boom in activity for the venomous arachnids, whose bite can kill a human in just 15 minutes.

“Because of the recent rain 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,” said Dan Rumsey, a worker at Australian Reptile Park, which issued a warning video on its Facebook page.

He continued, “Funnel-web spiders potentially are one of the most dangerous spiders on the planet in terms of a bite toward humans, so we have to treat it very, very seriously.”

Rumsey said the park has history working with funnel-web spiders’ raw venom — key to making anti-venom. He urged adults to catch the eight-legged creepy crawlers, particular male ones, so the park can continue harvesting the life-saving venom.

“Just by donating a spider to the Australian Reptile Park, you are contributing to saving people’s lives,” he said.

Rumsey said that no one’s died from a funnel-web spider bite in Australia since the 1980s.

There are 35 species of the funnel web, which thrive along Australia’s eastern coast from New South Wales to Queensland, according to Australian Geographic. Several species are known to have deadly bites.

The nocturnal creatures, which range in size from 1 cm to 5 cm, often times end up in people’s shoes or homes.
