A homeowner in New South Wales, Australia, made a terrifying discovery when she found her vacation home infested with thousands of dangerous wolf spiders that "play dead" to avoid being exterminated (video below).
Kathy Holmes, a teacher from Broken Hill, New South Wales, said the creepy creatures "just kept coming" even after being exterminated, according to the Daily Mail. A video Holmes posted online shows dozens of the spiders in a dustpan.
"I killed these in less than an hour they were relentless," Holmes wrote online. "And they often played dead the devious little eight legged Freaks."
"When I was [at the house] on Friday, the walls were moving with spiders. I have never seen so many before," Holmes told The Sydney Morning Herald.
"It gives me the heebie-jeebies," she said of the infestation.
Nearby Lake Menindee has been empty for several years, during which time many of the spiders have made the dried-out lakebed their home. Recently, the area has had a season of high rainfall, filling the dry lakebed -- so the spiders have looked for other places to live.
"It's beautiful here, except for the millions of spiders," said Ross Leddra, who lives near the lake. "You have to watch where you are sitting, and the kids are going crazy."
The wolf spiders in Holme's house are ground-dwelling creatures, and it's likely the spiders moved from dry lakebeds and streambeds after recent rains.
"Insects need water to survive, and so when you get conditions, such as a lot of water inland, it creates more habitat," said Stephen Doggett, an entomologist from the Department of Medical Entomology at Westmead Hospital. Doggett said the increase in rainfall in the area may have led to an increase in bugs like mosquitos.
"And then you get an explosion of predators that follow the insects," such as the spiders, said Doggett.
A wolf spider bite usually only causes local itchiness and pain, but can occasionally lead to swelling, extreme pain and nausea.
