Prolonged wet and hot weather produces conditions favourable to flystrike in livestock. Sheep in particular can be severely affected quickly.
Producers should lookout for wounds or sores that are infested with maggots. These wounds will often be noticeable because of a very strong smell or they are weeping liquid and staining surrounding wool. Common sites include the breech and around the pizzle of wethers and rams.
For small numbers of struck sheep, it may sometimes be possible to catch and treat individuals in the paddock. However, for larger numbers, yarding with crutching and/or chemical treatments may be best as soon as this can be accomplished.
