Officers in three police cars rushed to the scene, suspecting foul play Mr Howard says it was probably the most embarrassing day of his life

Police received a panicked call from a passer-by and attended a home in the northern suburb of Edgewater on Wednesday to investigate reports of a man yelling "Why don't you die?" loudly and repeatedly while a child was crying inside.

Admitting the commotion came from him, Rhys Howard confessed he had a fear of spiders and his partner usually killed them.

"I came out of the bedroom and I saw a spider on the floor … I freaked out as I normally do," he said.

"My partner was in the shower so I grabbed the first thing I saw, which was a nappy because we're toilet training our daughter, and I went down on my knees and I whacked it a few times.

"I was screaming, 'Why don't you die?' at the top of my lungs and repeatedly … because I'm terrified of them."

Mr Howard said his toddler became hysterical in a nearby room when she heard the screams.

His partner, Kara Loran, said Mr Howard was still shaking with fear when she came out to see what the noise was.

"This is pretty normal for him — he is an over-the-top person," she said.

Two police officers arrived shortly after Mr Howard's outburst.

"I'm very embarrassed, it's probably the most embarrassing day of my life, but it's hilarious as well," he said.

"We've just been constantly laughing for the past two days now about how big it has gotten.

"I think a lot of people can relate to having a fear of spiders. They're a nasty creature."

The couple said they would like to thank the passer-by for their concern and for contacting police.

Three police cars rushed to deal with the 'murder'

Wanneroo Police officer-in-charge Senior Sergeant Simon Hazel said three high-priority police vehicles were deployed as soon as the call was made.

"On arrival the officers were met at the door by a female who immediately started laughing," he said.

"They went and spoke to the male occupant … everyone had a great chuckle about it.

"Fortunately, it wasn't a serious job and everyone was OK. Except for the spider."

Senior Sergeant Hazel said the episode was a welcome bit of levity in a job that rarely saw the lighter side of life.

"It's a huge relief for the officers that they've rocked up and it's a little bit of arachnophobia as opposed to a homicide," he said.

"The positive that comes out of this is the neighbourhood watch philosophy of looking out for your neighbours and caring for the people in your street."

Senior Sergeant Hazel said the ordeal had also prompted a lot of one-liners being exchanged at the Wanneroo Police Station.

"Only in Australia — snakes, spiders, crocodiles and sharks, that's what we're known for, but it doesn't usually happen in the metro area. It's out of the ordinary," he said.

"We want to create the SRT — the Spider Reaction Team.
