Barber’s pole worm thrives in warm and moist conditions that most of Australia’s sheep regions have experienced recently. 

As a result, producers are battling infestations of barber’s pole worm outside traditional endemic regions for this parasite. 

Summer and autumn are the greatest risk periods to sheep health. However, eggs deposited in late summer and autumn may develop into infective larvae that persist throughout winter into spring.
