I don't mind bugs being in my house, it's when they're in my hair that it's horrid. Some jackass of a 'friend' has given me and lots of other people headlice. Horrid little sods, it's horrid to scratch your head and have a bug fall out, engorged on your blood.

Satisfying to crush them beneath your fingernails though. A nice pop as your stolen blood squirts out.
