I have severe arachnophobia, I live in Australia and you find those demon spawn everywhere...and we have so many venomous ones...so if I see one that's bigger than my pinky nail, it dies. The only one that gets a free pass are daddy long legs but if it goes within the vicinity of my bed, I'm gonna kill it.
Although because I'm so terrified of spiders I try to kill them by throwing shoes at them from a distance and my aim is terrible so they usually flee the scene unharmed anyway -___-
