What has everyone got such a problem with spiders? They kill flies and other bugs which actually spread disease. Spiders are a blessing. In Europe, there are none than can poison you. Whenever I see a spider on the floor, I move it to a high-up place like a bookshelf or similar using an empty toilet roll tube or similar so that it can easier build webs in the corner.
"Ditto" that, spiders are usually harmless and if unprovoked generally stay out of your way but we do have an exception in Australia we have a spider called The Funnel web and it is always out to get everything in its way mainly in mating season when they get antsy and skittish so they attack anything that moves and not only that but it is one of the most poisonous spiders in the world so yeah not a good combination of aggression and poison, then we have The white tail and its venom literally eats the flesh away near the bite it breaks down tissue so its not a good fella and it usually resides in houses then there is the Red back which is just god dam poisonous and can cause severe illness the ironic side to the red backs is the fact that they like man made structures to make their webs like brick work or concrete so wherever we are they are, the Black house spider and then there is the Trap door and their about the main culprits.

So yeah looks like Aussies lucked out with the critters lol we have some pretty bad snakes to, but then again we don't have bears and wild cats etc we just got all the poisonous things.

Flies do annoy me especially when you have your hands full and you can't swat them away and they always seem to find the same place on your face to annoy you every time they land. Do you ever talk to flies and tell them to F*** off and then you start to threaten them and tell them you will kill them if they don't p**s off haha and then you realise you are talking to a fly.
We have a big prob with mozzies we just had our biggest recorded case of Dangi fever in north Queensland over 500 case i think so yeah they are a big pest and you can even get in trouble for not checking your yard for ideal breeding places for mozzies so you have to be carefull about puddles of water and the like so they don't spread.
