Patent ID: 7152365

Claim:
A method of capturing insects, comprising: (a) providing an elongated housing having an affective length and a sidewall which extends between an upstream end and a downstream end to substantially surround a housing interior, said housing constructed to permit airflow between said upstream end and said downstream end, while impending passage of insects therebetween; (b) providing a movable closure at an upstream end portion of said housing, with said movable closure being biased into a closed position hindering access to the housing interior through said upstream end; (c) evacuating air from said housing, while retaining the movable closure in the closed position, thereby to establish a potential vacuum source within the housing interior; (d) placing said movable closure proximate to a target insect; and (e) creating air pressure within the upstream end portion of said housing that is less than ambient pressure at the upstream end whereby ambient air is drawn into the housing interior at a sufficient flow to cause said movable closure to move into an open position to thereby te create an entryway into the upstream rigion from the upstream end and to draw the insect into the upstream region to be trapped therein when the movable closure returns to the closed position.
