Spalding Labs – Proven, Organic-Safe Fly Control Spalding Labs has provided poultry producers with effective, science-backed solutions for long-term fly control since 1976. Our innovative approach focuses on prevention—killing flies before they hatch—with Fly Predators®, tiny beneficial insects that safely and effectively reduce pest fly populations without harmful chemicals. Fly Predators target and kill developing pest flies in organic matter like manure and litter, breaking the life cycle and dramatically reducing adult fly populations around poultry houses. This preventive, organic-safe method supports improved flock health, air quality, and worker comfort without relying on chemical sprays or baits. Our entomologist-led team works directly with poultry operations to design a customized, location-specific fly control plan that accounts for climate, housing type, manure management, and seasonal challenges. This tailored approach ensures the most effective, cost efficient, sustainable fly management program possible. Spalding also offers complementary products to help maintain cleaner, more comfortable facilities year-round, including Bye Bye Odor®, a microbial ammonia and odor eliminator that works at the source.
