Managing Tip Moth Infestations in Evergreen Trees

Identifying Tip Moth Damage

If you see larvae boring into the tips of your evergreen branches—especially in sandy, clay-like soils like those in Rio Rancho, NM—you’re likely dealing with tip moths. The adult moth lays eggs on terminal buds; the hatching larvae tunnel into the shoot, causing the tip to die and the tree to produce multiple new leaders, creating a bushy appearance.

Effective Control Strategies

Because the larvae are protected inside the stem, foliar sprays must be timed precisely before entry, which is difficult. A systemic soil-applied insecticide like Bayer Advanced Tree & Shrub Insect Control is more reliable: the roots absorb the product and move it to the foliage and stems, killing feeding larvae. Prune out and destroy dead tips to remove any larvae still inside. Always follow label directions and verify the product at your local nursery.
