• Hang traps in the trees by the end of June, to catch the apple maggot flies as they first attempt to lay eggs
• Hang one trap per ca. 100 fruit (after thinning) in each tree
• Hang one or two spheres for small trees and five or more traps for larger trees
• Place at least one trap on the side of the tree that faces any wooded or brushy area
• A second trap should hang on the south side of the tree
• Remove any leaves or fruit touching the traps
• Check traps weekly and, as needed, clean off the Stiky Stuff-coated insects and re-coat, or replace with a new coated trap
• If you do not use a scent lure, spray for apple maggots as soon as you catch a single adult (scent lures not recommended for backyard growers)
• If you hang a trap with a scent lure, wait until you have caught a total of five flies, whether all caught at once or one at a time
