A method of controlling pests includes applying a trap (10) to a plant. The A trap (10) includes a tube (12) of resilient material with a longitudinal slit (16) in its outer wall (14) for at least part of the length of the tube (12) and a number of apertures (18) in the outer wall. The resilience of the outer wall (14) urges edges of the outer wall on opposing sides of the slit (16) towards each other. The trap (10) is installed by extending the tube (12) around a trunk (20) of the plant, so that its two opposing ends (22,24) face each other, and inserting one end of the tube (22) inside the opposing end (24) by urging open the slit (16) at the outer end to enlarge the outer end and gripping the inner end by an inward resilient load from the outer wall of the outer end. |
