"I think a lot of people think that every spider is out to get them. In Australia, we have over 8000 species of spider and only two that will kill you, and they haven't killed anyone in 40 years.
Macquarie University post-doctoral researcher Lizzie Lowe says spraying gardens with broad spectrum insecticide destroys the eco-system, allowing only the "hardiest" of pests to flourish with unlimited resources.
"People may want to eradicate everything in the backyard, but you shouldn't actually want every insect in your garden dead. You want to have the good guys to help control the bad guys... so you don't have these massive outbreaks of creatures," Dr Lowe said.
