The caterpillars of the oak processionary moth infest oak trees, defoliating the tree and leaving it vulnerable to other threats. The main concern comes from the caterpillar's hairs which can cause irritation to the skin and allergic reactions.

How do I know if I have a Oak Processionary Moth problem?

If you think you’ve spotted signs of an oak processionary moth infestation, you’re in the right place. This quick guide to oak processionary moths will help you determine if it is in fact oak processionary moths you are dealing with.

The caterpillars of oak processionary moths infest oak trees, eating the leaves, weakening the tree and leaving it vulnerable to other threats. Oak processionary moth caterpillar nests are also a hazard to health as the hairs on caterpillars can cause skin irritation and allergic reactions.

First identified in London in 2006, oak processionary moth infestations have spread to some surrounding counties including Surrey and other parts of south east England. See the latest distribution map.

Oak processionary moths spread by flying from one tree to the next. Normally they stay close to the tree they were on as a caterpillar.

The caterpillars have black heads and grey bodies covered in long white hairs. 

Nests are commonly found in early summer, in the trunks and branches of oak trees. 

At Beaver we practice Integrated Pest Management (IPM). This is a sustainable approach to managing pests by combining biological, cultural, physical and chemical tools in a way that minimises economic, health, and environmental risks.

Oak Processionary Moth Nest Removal

Nests are generally located above the ground areas of the tree and prefer sheltered areas. Gaining access can be done through use of a M.E.W.P or rope access. Our trained technicians will use high suction industrial vacuums to remove the webbing and caterpillars. All necessary PPE is worn and hazardous biological waste is removed from site.

Oak Processionary Moth Treatment

We use environmentally friendly insecticides and specialist machinery to treat the moth infestation effectively. The treatment is most effective between the 1st and 3rd growth stages which is generally mid-April to the end of May.
