Oak Processionary Moth Infestation in Epsom

Earlier this summer, the team at Arborlife Tree Services was contacted by a homeowner in Epsom who had spotted unusual web-like nests high up in the canopy of their mature oak tree. Upon inspection, we confirmed it was an infestation of the Oak Processionary Moth (OPM) — an increasingly common pest in Surrey that poses serious risks to both tree health and public safety.

Because OPM caterpillars have tiny, toxic hairs that can cause skin irritation, eye inflammation, and respiratory issues, it was crucial to deal with the problem promptly and safely.

How We Safely Removed the OPM Nests

Initial Inspection & Risk Assessment

Our qualified arborists conducted a full site inspection, identifying several silk-like nests containing OPM larvae along the trunk and branches. We assessed the level of infestation, proximity to public footpaths, and access requirements.

Protective Equipment & Safety Measures

Due to the hazardous nature of OPM, our team wore specialised PPE, including full-body suits, gloves, and respirators. We established a secure perimeter to keep residents and pets safely away during removal.

Mechanical Removal of Nests

Using rope access and extendable poles, we carefully removed each nest without disturbing the caterpillars unnecessarily. Every piece of material was sealed in biohazard bags to prevent contamination and ensure safe disposal.

Disposal & Site Clean-Up

The contaminated nests and debris were disposed of in accordance with DEFRA and Forestry Commission regulations. Once completed, we sanitised tools and equipment to prevent cross-contamination to other sites.

The Importance of Professional OPM Removal

Attempting to remove Oak Processionary Moth nests without proper equipment and training is dangerous. Even old, abandoned nests can release harmful hairs when disturbed.

Hiring trained professionals like Arborlife Tree Services ensures:

• Safe and compliant removal procedures
• Protection for people, pets, and wildlife
• Prevention of further spread to nearby trees
• Full reporting for compliance where needed
