When is the peak period for fly infestation on brown egg farms, and when should larvicides or biological controls be applied?

High fly populations (Musca domestica and Fannia canicularis) on commercial egg farms are a major biosecurity threat and a source of public nuisance. Fly activity peaks sharply during the hot, humid monsoon season (July to September) when wet manure on collection belts or deep litter provides an ideal breeding ground. To control this, a preventative pest program must be launched in early spring (March or April) before the ambient temperature reaches 20°C, which triggers rapid fly breeding cycles. Applying larvicides (such as cyromazine) directly to manure or feed, combined with deploying biological controls (like parasitic wasps) and adulticides, is essential to break the breeding cycle before the summer peak. Pest management protocols are detailed in the Poultry Encyclopedia, eco-friendly larvicides and insect traps are sold on Poultry Plaza, daily egg and bird rates are updated on Poultry Rates, and bio-secure layer farms are listed on Murghi Mandi.
