Flies and ticks reduce livestock health and farm productivity
Warm weather brings longer days but also increases the risk of external parasites in livestock. These pests can cause stress, reduce weight gain, lower milk production, and in severe cases, lead to death. Managing these parasites is essential for maintaining animal health and farm performance.
Flies are one of the most common problems during summer. In many regions, horn flies, face flies, and horse flies affect cattle. Horn flies are small and usually found on the back and sides of animals. Face flies crowd around the eyes and nostrils, causing irritation. Heavy fly pressure stresses livestock and reduces performance.
Ticks also pose serious health risks. The Asian longhorned tick has spread in recent years and can carry Theileria, a disease that may cause anemia and death. Ticks can also spread anaplasmosis, which damages red blood cells and weakens animals.
Farmers can manage parasites using a combination of methods. Good pasture management helps reduce tick habitats by controlling tall grass and unwanted vegetation. Fly traps placed in barns or gathering areas help control local fly populations.
Insecticides are widely used and can be applied as sprays, rub-ons, or tags. Pour-on and rub-on products allow animals to treat themselves while moving through specific areas. Spray treatments are applied directly to affected areas.
Mineral supplements with insect growth regulators help control flies by stopping larval development in manure. For best results, these should be introduced before the fly season begins.
Fly tags release insecticides slowly and offer long-term protection. However, farmers should rotate their products each year. This reduces the risk of pests developing resistance and ensures continued effectiveness.
