Chemical Controls

Although chemicals are important, complete reliance is not effective. The most effective use of chemicals is in conjunction with natural enemies and proper sanitation. Overuse of chemical insecticides will speed up the resistance problem and kill the beneficial predators and parasites in the manure.

Baits can be used to control adult flies that are attracted to livestock and poultry operations.

Sprays can be used to treat areas where adult flies congregate. Avoid spraying breeding sites; doing so will damage the natural enemy population.
