Abstract
An insect trap which comprises a chimney member adapted to allow a flow of air to be forced therethrough, a reservoir of insect attractant which under the influence of the flow of air is evaporated and borne as a stream of attractant vapor emanating from the chimney member into the surrounding atmosphere, and a tacky substance provided inside the chimney member which will trap flying insects lured therein by the stream of attractant vapor.
Claims8
An insect trap, comprising:
- a chimney member;
- an electrically powered heater located underneath the base of said chimney member with the base of said chimney member being mounted directly to said heater so as to allow access thereto only through the top of said chimney;
- a reservoir containing an insect pheromone, located adjacent to and above said heater;
- and
- a tacky substance located inside said chimney member;
- whereby the heater evaporates the insect pheromone and generates a convection flow of air which carries the pheromone out of the top of the chimney into the surrounding atmosphere and the insects thereby lured by the pheromone through the top of the chimney become trapped by the tacky substance.
