A tsetse fly trap typically works by attracting the flies with a bait and then trapping them in a device. The design combines a visual attractant with an odor attractant to lure the flies.
The visual attractant is often a blue and black cloth, which is believed to mimic the color of animal skin, which tsetse flies find attractive. The odor attractant is a chemical compound that mimics the scent of animal urine or other organic material.
Once the tsetse flies are lured to the trap, they are typically captured by the insecticide embedded in the trap.
Tsetse fly traps can be an effective tool for controlling the spread of diseases such as sleeping sickness, which is transmitted by tsetse flies. By reducing the population of tsetse flies in an area, traps can help to reduce the risk of disease transmission to humans and livestock.
