House flies are an important filth breeding pest in both rural and urban areas. Commercial baited fly traps are commonly used to attract flies by vision and odor, but typically they capture and kill just a small percentage of the fly population. To improve trap performance, a 46 cm wool cord (6 mm diameter) was dipped in 2.5% imidacloprid (Maxforce Spot Bait) and looped around a Farnam Musca-Doom Disposable Fly Trap baited with commercial fly attractant. Flies (300-500) were released into screened cages with sugar water, water, and fly medium as nutrient sources. Traps were hung and fly counts were recorded over 48 hours. Without treated cord, unbaited fly traps captured and killed 5% of the fly population, whereas, baited fly traps captured and killed 6% of the population. When treated cord was wrapped around the unbaited trap, 84% of flies were killed. When a baited trap with a treated cord was used, 75% of flies were killed. A treated cord loop hung alone killed 95% of the fly population. Treated fly cords can be used to enhance the performance of commercial baited fly traps or could be used alone for control of flies.
