If I find OPM nests or caterpillars in my trees, what should I do?

We strongly advise against treating this pest yourself. The health dangers posed by the caterpillar hairs, thousands of which can be in the nests are potentially high. In addition, to effectively manage OPM, the job must be done at just the right stage in the moth's life cycle by someone professionally trained to carry out the task.

Bartlett Tree Experts have highly qualified and trained staff who can advise and treat your tree. We offer a range of effective control methods that include surveying, bio-control treatments, botanical insecticides, insect growth regulators and systemic tree injections. Regular monitoring of oak trees in spring and early summer is recommended. Early detection can prevent infestation and aid in effective management.
