The tsetse flytrap

The flytrap solution

Research at the Kenya Institute had shown that the tsetse fly is most common near game parks, where it is carried by buffalos and elephants. The fly then moves on to cows on neighbouring land, with devastating effects for local farmers.

The research had also shown that the tsetse fly could be tricked into thinking that a cloth model of a cow was a real animal (a similar idea to a scarecrow). The flies are attracted by the smell from two bottles hanging on the model, one containing acetone and the other cow's urine. They land on the model to suck the 'cow's' blood, and are lured into a trap where they die.

A charity called World Neighbours, which was involved in the research, invited Practical Action to join them in piloting the tsetse flytrap in Kathekani.

The success of the project surprised everyone. When it began, with ten traps, each trap caught 2,000 flies every day (a total of 20,000 flies). Now there are 160 traps in the Kathekani area, and just 22 flies a day visit each trap (a total of 3,520 flies). This shows how much the fly population has fallen since the introduction of the traps.
