Responding Quickly to Oak Processionary Moth in Fetcham – Specialist OPM Nest Removal by ArborLife Tree Surgeons

Rapid Oak Processionary Moth Removal in Fetcham Protects Residents and Mature Oak Trees

When Oak Processionary Moth (OPM) nests are discovered, swift action is essential. These invasive caterpillars don't just threaten the health of mature oak trees—they also present a genuine health risk to anyone who comes into contact with their toxic hairs.

Recently, ArborLife Tree Surgeons attended Barclay Close in Fetcham, Surrey, to safely remove active Oak Processionary Moth nests from a mature oak tree situated close to residential properties.

Wearing specialist protective clothing and using professional climbing techniques, our qualified arborists carefully removed the nests before they could pose a greater risk to local residents and pets.

Why Professional OPM Removal Matters

Oak Processionary Moth infestations should never be ignored.

Each caterpillar carries thousands of microscopic urticating hairs that can easily become airborne when disturbed.

These hairs may cause:

Painful skin irritation
Itchy rashes
Eye inflammation
Sore throats
Respiratory discomfort
Allergic reactions

Even after the caterpillars have left the nest, the abandoned nests can remain hazardous for many months.

Professional removal significantly reduces the risk of exposure.

Specialist Safety Procedures

Removing Oak Processionary Moth requires far more than standard tree surgery equipment.

During this project in Fetcham our team worked using:

Specialist disposable protective clothing
Full face protection
Respiratory protection
Professional climbing equipment
Controlled nest removal techniques
Secure containment bags for hazardous material

Every stage of the operation was planned to minimise the release of toxic hairs into the surrounding environment.

Working Safely at Height

Many OPM nests are found high within the canopy of mature oak trees, making access both technically challenging and potentially hazardous.

Using advanced rope access techniques, our arborists safely positioned themselves throughout the canopy before carefully removing each nest by hand.

The image below shows one of our climbers suspended within the oak canopy during the removal process while wearing full protective equipment.

Protecting Fetcham's Mature Oaks

Oak trees are among Surrey's most valuable landscape features, providing shade, biodiversity and character to gardens, estates and public spaces.

Where possible, ArborLife aims to preserve the health of the tree while safely removing the infestation.

Early intervention helps reduce:

• Defoliation of oak trees
• Stress on mature specimens
• Future infestations
• Public health risks
• Long-term treatment costs

Frequently Asked Questions

How can I tell if an Oak Processionary Moth nest is active?

Fresh nests are usually white or grey silky webbing attached to the trunk or larger branches. You may also see caterpillars travelling together in characteristic nose-to-tail processions.

Are old OPM nests still dangerous?

Yes. Even after the caterpillars have gone, thousands of toxic hairs remain within the nest and can still cause serious irritation.

What should I do if I find an OPM nest?

Keep children and pets away from the tree and contact a qualified tree surgeon experienced in Oak Processionary Moth removal. Never attempt to disturb or remove the nest yourself.

Can Oak Processionary Moth damage healthy trees?

Repeated infestations can weaken mature oak trees through repeated defoliation, making them more susceptible to drought, disease and secondary pests.
