A heating device (1) forcibly generates an air draught which passes into the surroundings via a supply (3) of insect attractant, through an outlet (2) and out of a hole (10). A vapour which attracts insects is taken along with the air draught, with the result that a stream of attractant vapour escapes at the top from the outlet (2). Flying insects of the type attracted by the attractant used in the supply in each case are attracted to the insect trap, pass into it and are trapped by a sticky substance provided on an inner casing (4). <IMAGE> |
