I have to say I find it amusing how some of you never see any spiders including red backs despite living here for years. Must be city dwelling
I can say that this year alone in Albany WA I've seen a couple of dozen red backs and a few wolf spiders whilst doing the garden. When at work in Wagin (country WA) I couldn't even begin to list how many red backs I've seen. See a few huntsmen a year and white tail spiders too.
So they are there. But I know when I first came over I was paranoid about spiders and would check the corners of rooms etc when I went in them. Now I don't even worry, infact the Red Back siting on the garage roll door I've just left there to happily while away her life until she moves...
Not to mention the Christmas spiders and golden orb spiders I've seen too...
Surprisingly I've not been bit and I don't know anyone who has been bit in the past few years that I've been here.
And like the above, I'll take the spiders over the stink bugs!
