I am phobic of spiders too. Sleep with a flyswatter where you can reach it while you sleep. Ask your roomate to go through the kitchen and around the house and find the spider and kill it or haul it outside far away from the house. If it has been a few days, the spider is no longer in the kitchen. My home is larger than yours I'll bet ( I live in the US) and the last tiny spider I saw walked from one end to the other overnight. The spider is outside by now looking for water to drink and a meal. There are no bugs inside.

I would just love to see Australia, but then I watched this show on the animal planet station about how 3 of the top ten venomous spiders live there. And then there are the snakes...
