Harvest Mite

A very tiny creature living in long grass but which can be carried into homes on clothing or the coats of dogs. Can give a very irritating bite.


Harmless spider-like creatures with eight exceptionally long, thin legs. They do not spin webs but occasionally wander into homes.

Head Lice

A medical problem more common since the development of “resistant” strains of lice.

The head louse is a blood-sucking parasite about 3mm long, greyish, but adapting to the hair colour of its host. The tiny, pearly eggs or “nits” are cemented to the hair close to the scalp and there are three nymphal stages. The eggs hatch in about eight days and the complete life cycle takes about 18 days.

The bites cause inflammation and itching, which leads to affected children scratching the scalp, introducing secondary infections such as impetigo or eczema, or literally feeling lousy.


Twice the size of the common wasp and brown and yellow instead of black and yellow. Builds nests in hollow trees and similar sites and individuals only occasionally enter houses.
