Oak Processionary Moth Nest Removal in Weybridge – Safe OPM Treatment by ArborLife Tree Surgeons

Protecting People and Trees: Oak Processionary Moth Nest Removal in Weybridge

Oak Processionary Moth (OPM) is one of the most serious tree pests affecting oak trees across Surrey and Greater London. Not only does it damage the health of mature oak trees, but the tiny hairs covering the caterpillars can also pose significant health risks to people, pets and wildlife.

Recently, our specialist team at ArborLife Tree Surgeons carried out the safe removal of several Oak Processionary Moth nests from mature oak trees at Pine Grove Mews, Weybridge.

Using specialist climbing techniques and industry-approved removal methods, the nests were carefully removed and disposed of safely, protecting local residents while helping preserve these beautiful mature oak trees.

What is Oak Processionary Moth?

Oak Processionary Moth (Thaumetopoea processionea) is an invasive species that feeds almost exclusively on oak trees.

The caterpillars are easily recognised by travelling nose-to-tail in long "processions", which gives them their name.

Although they eventually become harmless moths, it is the caterpillar stage that presents the greatest danger.

Why is OPM Dangerous?

Unlike most garden pests, Oak Processionary Moth is a public health issue.

Each caterpillar is covered in thousands of microscopic hairs containing an irritant protein that can become airborne.

Contact with these hairs may cause:

Severe skin irritation
Painful itchy rashes
Eye irritation
Sore throats
Breathing difficulties
Allergic reactions

Pets, particularly dogs, can also suffer serious reactions after sniffing or touching nests.

For this reason, OPM nests should never be touched or removed by untrained individuals.

Frequently Asked Questions

How do I know if my oak tree has Oak Processionary Moth?

Look for silky white webbing on the trunk or larger branches between late spring and summer. You may also see caterpillars travelling nose-to-tail in long lines.

Is Oak Processionary Moth dangerous?

Yes. The caterpillars have thousands of tiny toxic hairs that can cause skin irritation, eye problems and breathing difficulties in both people and animals.

Can I remove an OPM nest myself?

No. OPM nests should only be removed by trained professionals wearing specialist protective equipment. Disturbing the nests can release harmful hairs into the air.

When is OPM most active?

The caterpillars are usually active from May until July, although nests may remain hazardous for much longer.
