|Codling Moth_statewide (Horticulture/Urban IPM)
Commonly referred to as “the worm in my apple,” codling moths are the primary insect pest of apple and pear in Montana. The adult codling moth typically emerges during apple bloom across the state, which can help growers and homeowners time chemical controls.
There are several options for managing codling moth in backyard plantings. Chemical controls are applied after petal fall and should never be applied during bloom when risk to harming pollinators is high.
