Like the BG-Sentinel, the patent-pending mixture of three different components of human skin odour is a result of 15 years of academic research into the host-finding behaviour of mosquitoes.

A specially designed dispenser releases each compound in a specific quantity, composing a finely tuned pattern of artificial skin emanations. This forms a unique "perfume" for an added sensitivity and specificity of the BG-Sentinel trap.

Extra care was taken to ensure a long-lasting release of the components: the dispenser remains effective for up to five months.
