Stable Fly Management

In previous years the Shire of Gingin has been affected by large populations of Stable Fly (Stomoxys calcitrans L.), particularly in the warmer weather. As a result the Shire works closely with the Department of Primary Industries and Regional Development (DPIRD) with a collective view to combating the problem.

Stable Fly can be a serious pest to livestock owing to its painful bite when it draws blood during feeding. 

Association with Raw Poultry Manure

DPIRD has discovered an association between the use of poultry manure and rotting vegetable matter in relation to the breeding of the stable fly. Therefore commercially derived untreated poultry manure must not be stored or used on land for agricultural activity or transported within the Shire of Gingin (in accordance with the Biosecurity and Agriculture Management Act 2007). Additionally, farmers feeding bulk vegetable waste to their stock may also be contributing to stable fly breeding, particularly if the vegetable waste is not spread thinly in paddocks.

The Shire of Gingin requests that the public be vigilant regarding Stable Fly infestations and report any fly breeding or excessive numbers to DPIRD ( on 1800 084 881 or download DPIRD's MyPestGuide Reporter app.

Please see the Stable Fly Action Group website for more information.
