Mosquitos, midges, tsetse flies, lice of head, body, and many other places... all those bloodsuckers could well be away from us IMHO.

I used to be a walking feast for mosquitos and midges until I started taking in a teaspoon of vegemite per day. It took a couple of weeks to work, but they no longer bother with biting me any more. Huzzah.

Up to you whether the cure is worse than the disease.
