There are 22 species of tsetse flies that transmit a group of parasites, causing the disease trypanosomiasis, which in one form or the other is prevalent throughout most of Africa. It accounts for sickness and deaths among livestock and agricultural losses, thus enhancing rural poverty. In humans, trypanosomiasis is better known as 'sleeping sickness', which is endemic in some parts of Africa.

Vestergaard manufactures various types of tsetse fly traps and targets. These traps and targets, in blue and/or black attractant cloth screens, are impregnated with deltamethrin, a biodegradable insecticide, and function by attracting the tsetse flies to the cloth screens that trap and/or kill them. This technique reduces tsetse numbers significantly.

Traps and targets can both be used to eliminate a vast portion of the tsetse population. While targets are used only for control, traps can also be used for entomological surveillance. Moreover, tsetse traps have the advantage of being costeffective and community-based. For scientific purposes, the traps can be supplied without insecticide.

Different models of traps and targets have been designed for use against specific target species in specific environments. The insecticide treatment of the traps and targets will last approximately one year depending on local conditions. The colour fastness of the fabric will last two to three years, also depending on local conditions. Specifications of different models are provided in this catalogue.
