The major cause of maggot damage to plums and gages is the caterpillar of the plum fruit moth. This plum fruit moth trap uses the pheromone scent of the female moth to attract and catch male moths. Keep your plum trees maggot free with the plum moth pheromone trap, a simple and effective way to reduce fruit damage caused by plum moths. The pheromone lure attracts male plum moths, stopping them from mating. Helps prevent maggots by disrupting the life cycle of the plum moth. Just hang the trap in your tree and replace the lure after 5 weeks. Pesticide-free and safe for beneficial insects. How It Works: The pheromone lure attracts male plum moths to the trap. The sticky surface inside traps the moths. This reduces the number of male moths and therefore reduces the number of fertilised female moths. The trap should be placed in the garden at the end of May or after petal drop. If the spring weather is exceptionally warm, or in sheltered urban gardens, it may be helpful to install the trap in mid-May. In the garden, one trap can monitor up to three average-sized trees. It should be hung at around head height on the windward side of the tree (or group of trees). Find out how to protect your fruit trees with our guide. The trap contains everything you need for a year, and the refill allows the trap to be used for a second year.
