<p>There is disclosed an apparatus for dispersing an attractant having a housing (10) having a first plurality of apertures (11), a rotatable insert (20) for carrying the attractant and positionable within said housing, the insert including a second plurality of apertures (22) which can be aligned with the first plurality of apertures (11) so as to provide a plurality of openings (41) for the distribution of said attractant between the insert (20) and said housing (10) and a closure adapted (30) to engage the housing (10) and retain the insert (20) therein whereby selective rotation of the insert (20) relative to said housing (10) varies the area of the plurality of openings (41) in order to vary the rate of dispersion of the attractant.</p> |
