Treatment of struck sheep

Shear struck wool and a 5 cm barrier of clean wool around the strike, close to the skin to remove maggots. Unless wool is shorn off it is likely that maggot trails will be missed and sheep will remain struck.
Collect the maggot-infested wool into a maggot-proof (plastic) bag and leave the bag in the sun for a couple of days to kill all maggots. This breaks the life cycle. Don’t rely on registered flystrike dressings to kill maggots – some are incapable of killing large maggots and many maggots escape treatment by dropping from the sheep and burrowing into the soil before the insecticide can be applied. Unless maggot infested wool is collected and bagged, most maggots will survive and pupate and come back as adult flies!
Apply a registered flystrike dressing to the shorn area to prevent re-strike. If necessary, these treated sheep may be jetted or backlined along with other susceptible sheep to provide long-term flystrike protection.
Remove struck sheep from the mob. Leaving struck sheep in the mob attracts blowflies. Moving struck sheep to a ‘hospital’ paddock allows closer monitoring of recovery and reduces the risk to the rest of the mob.
Adult ewes that sustain repeated flystrike (crutch or body) should be culled from breeding programs to improve overall flock resistance to flystrike.
