In their search of the perfect piece of fruit to lay their eggs in, the female Apple Maggot (Rhagoletis pomonella) just can't resist a plump red apple. These red spheres will appeal to that weakness and entice her right over. However, once they land on this trap, the adhesive will grab them and their quest will be over. Spread traps throughout your trees and remove, clean and re-use them once every 2-3 weeks or when they become covered with insects.
If you are dealing with an infestation, your best course of treatment will be to use these traps with beneficial insects and other products such as Surround® WP, horticultural oils and yellow sticky traps.
