Introduction

Muscidae sp. - Copyright Alan Hadley

The family Muscidae contains many non-biting (nuisance) flies and blood sucking (biting) flies. There are only two nuisance flies of veterinary importance, these are the Musca spp. and Hydrotaea.

Nuisance flies are not only irritating to animals, but can also carry serious diseases and so should be controlled from an animal welfare point of view.
