Sheep farming is an important part of livestock care, but one serious problem farmers face is blowfly strike in sheep. This condition can cause stress, pain, and even death if left untreated. Blowfly strike happens when flies lay eggs on the skin, and the hatched maggots eat into the flesh of the animal.
Farmers know that healthy flocks are key to good production. When sheeps blowfly strike occurs, it reduces wool quality, lowers weight gain, and creates welfare concerns. Understanding what causes this issue, how to spot it early, and ways to prevent it can save animals and protect farm income.
- Blowfly strike is a global sheeps health issue.
- It needs regular monitoring and care.
- Quick treatment ensures better recovery.
What is Blowfly Strike in Sheep?
Blowfly strike is a condition caused by green or blue bottle flies. These flies are attracted to moist and dirty areas on the sheep’s body. Once they lay eggs, the larvae (maggots) grow fast and begin to damage the sheep’s skin. This leads to infection and severe wounds.
When we say blowfly strike sheep, we mean a sheeps affected by this fly attack. The disease is most common in warm and humid weather, especially during the summer months. It is a painful problem that needs attention as soon as possible.
Key facts:
- Blowfly strike can spread quickly within a flock.
- Wet wool, urine stains, and dirty back ends attract flies.
- Prevention is easier than cure.
Causes of Blowfly Strike Sheep
The main cause of blowfly strike is fly activity. Female blowflies search for moist areas on the sheep, such as wounds, dirty wool, or skin folds. They then lay eggs, which hatch into maggots.
Poor hygiene and lack of shearing can also make sheep more likely to get the disease. For example, a sheep that has not been crutched (wool removed from the back end) is at high risk. Rain, humidity, and high temperatures give the perfect environment for blowflies to thrive.
- Warm and humid weather conditions
- Dirty or damp wool around the tail
- Cuts, wounds, or untreated skin infections
- Long wool without shearing or crutching
Signs of Blowfly Strike Sheep
Farmers need to check their flocks daily for signs of sheep blowfly strike. Early detection can save an animal from pain and suffering.
The first signs are changes in behavior. Sheep may appear restless, stamp their feet, or bite at affected areas. As the maggots grow, the wool may become damp, discolored, and smelly. In severe cases, the sheep may stop eating and lose weight.
Symptoms to watch for:
- Irritation, scratching, or constant movement
- Dark patches of damp wool with a bad smell
- Visible maggots on the skin
- Weakness or loss of appetite

Impact of Blowfly Strike on Sheep Farms
The effect of blowfly strike in sheep goes beyond animal suffering. Farmers face financial losses due to reduced wool quality, treatment costs, and in severe cases, loss of animals.
Sheep blowfly strike also reduces growth rates, as affected animals stop feeding properly. Stress from pain and infection can cause long-term harm. For commercial farms, this means lower income from meat and wool production.
- Poor wool quality due to damaged skin
- Higher veterinary costs for treatment
- Increased workload for farm workers
- Risk of losing valuable breeding stock
Preventing Blowfly Strike in Sheep
Prevention is the best way to protect flocks from blowfly strike sheep. Farmers should focus on good hygiene, regular shearing, and chemical protection when needed.
Shearing in spring removes heavy wool and reduces risk. Crutching and dagging (removing wool around the back end) help keep sheep clean and less attractive to flies. Fly repellents and insecticides can be used during peak fly season.
Prevention steps:
- Shear sheep before summer to reduce wool buildup
- Keep back ends clean by crutching or dagging
- Use approved fly treatments or repellents
- Manage wounds quickly to prevent fly attack
Treatment of Blowfly Strike Sheep
When a sheep is affected, fast treatment is important. The first step is to clip away the dirty wool around the struck area. This helps expose the maggots and allows medicine to reach the wound.
Sheeps with blowfly strike need immediate care. Farmers often use special insecticides to kill the maggots. After treatment, the wound must be kept clean and checked daily. Severely affected animals may need veterinary support and antibiotics for infection.
- Clip wool around affected areas
- Apply insecticide sprays or dips
- Give supportive care and pain relief
- Monitor until full recovery
Seasonal Risks of Blowfly Strike in Sheep
The risk of sheeps blowfly strike is highest in warm and wet seasons. In many countries, this means spring and summer. Farmers must prepare in advance to protect their flocks.
During peak fly season, sheep should be checked at least once a day. Young lambs and older sheep are at higher risk. Farmers should also note that weather changes, like sudden rains, can trigger a rise in fly numbers.
Seasonal care tips:
- Watch flocks more closely in summer
- Apply preventative treatments before fly season
- Shear and crutch sheep before warm months
- Reduce damp areas in fields when possible
Long-Term Control of Blowfly Strike Sheep
Good farm planning is needed to control blowfly strike in sheep over the long term. Relying only on chemicals can lead to resistance in blowflies. Farmers should combine hygiene, breeding, and management practices for lasting results.
Breeding sheep with less wrinkled skin helps reduce strike risk. Improved nutrition keeps animals stronger and less likely to suffer. Integrated farm management, with both natural and chemical methods, is the best approach.
- Use resistant sheep breeds where possible
- Keep pastures clean and dry
- Rotate fly treatments to prevent resistance
- Train farm workers to identify early signs
FAQs About Blowfly Strike
Blowfly strike is a condition where flies lay eggs on the skin, usually in damp or dirty wool. The eggs hatch into maggots that eat the sheep’s skin, causing pain and infection.
Sheeps blowfly strike is mainly caused by warm weather, high moisture, and dirty wool. Flies are attracted to damp or soiled areas, especially around the tail and wounds.
Sheeps with blowfly strike often look restless, scratch or bite themselves, and have patches of wet, smelly wool. In some cases, maggots may be seen on the skin.
Treatment includes clipping away dirty wool, applying insecticides to kill maggots, and cleaning the wound. Severe cases may need veterinary care and antibiotics.
Yes. Preventing blowfly strike sheeps involves shearing before summer, keeping wool clean, using repellents, and checking flocks daily in fly season.
Conclusion
Blowfly strike in sheep is one of the biggest challenges for sheep farmers worldwide. It causes pain for animals and financial loss for farms. By knowing the causes, spotting signs early, and focusing on prevention, farmers can keep their flocks safe.
Caring for sheeps means acting fast when sheep blowfly strike occurs and building long-term strategies to reduce risks. With good farm management, strong hygiene, and seasonal planning, blowfly strike can be controlled effectively.
