Common Household Spiders – Friend or Foe?
Spiders are unsightly household pests that are extremely common throughout Australia. Some of these eight-legged arachnids are highly venomous, hence provoking fear and even phobias in some people. Spiders are also known to be useful pest control agents in some homes, however, there is always the risk of overpopulation which may lead to spider infestation – and as the old saying goes, ‘Enjoy everything in moderation’… Unless they are venomous.
