Hang the red ball traps in the proximity to fruit at eye level, on the south or southeast side of the tree. For large, mature trees, use up to 6 traps per tree. If using more than one trap per tree, place some traps facing a wooded or brushy area.
Hang each trap on a sturdy stem about 1' above a dense patch of fruitlets, and remove any foliage to create a leaf-free area that is at least 18" in diameter.
The apple maggot lures increase the efficacy of the traps by attracting flies from a distance. Situate the lure on the same limb about 12" behind the trap (so the lure is closer to the trunk than the trap is), on the underside of the branch. Leave the packaging fully intact on the lure; the apple essence scent penetrates the plastic.
