Patent ID: 8356444

Claim:
A wasp trap, comprising; a vapour chamber detachably couplable to a collection chamber; the vapour chamber having a property to form a vapor that is based on an attractant material within the wasp trap, the vapour chamber including: a wasp entrance defined in a wall of the vapour chamber; a restriction part connected to the vapour chamber, the restriction part being sized to control the movement of wasps from the vapour chamber to the collection chamber when coupled, and the restriction part includes a surface sloping downwardly towards an opening into the collection chamber; a tubular inlet extending downwardly from the restriction part; and the collection chamber including: a housing, an entrance into the housing, and a self-closing part designed to automatically seal the entrance when the collection chamber is detached from the vapour chamber in order to prevent escape of wasps from the collection chamber; the self-closing part includes a resilient diaphragm with three or more inwardly-extending resilient closure elements, and the diaphragm is dome shaped toward an interior of the housing so that the closure elements are more easily deflected to open the diaphragm in an opening direction toward the interior of the housing; wherein during coupling of the vapour chamber and the collection chamber, the tubular inlet is insertable through the diaphragm which will deflect the resilient closure elements in the opening direction to open the entrance, and is thereafter removable to allow the resilient closure elements to return to their undeflected position to close the entrance; the wall of the vapour chamber is substantially transparent, at least a portion of the collection chamber is transparent, and the restriction part is opaque.
