Identifying and Managing Pitch Moth Infestations: Expert Advice from Trickinnex Tree Trimming & Falling LLC

March 3, 2025

Pitch moth infestations can cause significant damage to pine and coniferous trees, weakening their structure and making them more vulnerable to disease. These pests, including species like the Western Pitch Moth (Synanthedon sequoiae), lay eggs on tree bark, and their larvae tunnel into the cambium, feeding on sap and causing excessive resin production. If left untreated, pitch moth damage can lead to branch dieback and structural instability. At Trickinnex Tree Trimming & Falling LLC, we specialize in identifying and managing pitch moth infestations to keep your trees healthy and thriving.

Signs of a Pitch Moth Infestation

The most common indicator of pitch moth activity is the presence of large, sticky resin masses on the trunk or branches of pine trees. These formations occur as a defense response from the tree when larvae burrow beneath the bark. Other signs include wilting or dying branches, weakened tree growth, and entry holes in the bark surrounded by pitch buildup. If you notice these symptoms, it's crucial to take action before the infestation spreads.

How to Protect Your Trees from Pitch Moth Damage

Preventing pitch moth infestations starts with proper tree maintenance. Avoid unnecessary pruning during peak egg-laying seasons (spring to late summer), as fresh cuts can attract adult moths. Regularly inspecting your trees for early signs of damage and promoting overall tree health through proper watering and fertilization can also deter infestations. Our team at Trickinnex Tree Trimming & Falling LLC offers expert tree trimming, bark inspections, and treatment solutions to mitigate pitch moth damage and prevent future outbreaks.
