An apparatus to project toward a tree to disburse a pheromone, comprising :a releaser (20) removably adjacent to a capsule (25) via an extension (120); whereby said releaser (20) and said capsule (25) are disposed adjacent to each other in a deployable state (180), then the releaser (20) separates from the capsule (25) but is still connected via said extension (120) whereby inertia causes said releaser (20) to move away from said capsule (25) into an attachment state (200). A method of applying a pheromone onto a tree branch, comprising: positioning a releaser (20) to a first end (122) of an extension (120); positioning a capsule (110) to a second end (124) of an extension (120); positioning the releaser (20) adjacent to the capsule (110) so that the member (10) is in a deployable state (180); projecting the member (10) in its deployable state (180) whereby inertia causes said releaser (20) to separate from said capsule (110) and form an attachment state (200).
