My list is very subjective.
Cockroaches (pest) is my N.1 on the list
N.2 Ticks!!! The fuckers rain from the trees and latch onto you!!!
N.3 is shared by parasites, any worms, lice, fleas, you name it;
N4. Leeches. Because fuck leeches. They are slow, yet they will still get you, and unless you have coated yourself in DEET they will bite you, and the bite will bleed for a while, and if you are like me you may get an allergic reaction.
Anything that can be reasonably warded off with regular repellent and/or window screens gets a pardon from me.








Where I live I can assure you they drop from the trees. Are you in Australia as well? Every time I removed ticks they were on my neck, shoulders, armpits and breast areas.
