Who we help
The same moth, very different problems
A single garden oak and an oak-lined golf course present identical biology and entirely different management questions. Choose the setting closest to yours.
Whatever the setting
Two things stay the same
Get the identification confirmed, and make sure the sighting is officially reported.
Not sure what you've found?
Ask an OPM Expert
Send clear photographs of the tree, the caterpillars or the suspected nest and our team will give you an initial visual opinion to help you understand your next steps.
Photo identification is preliminary and may not always be conclusive. A professional site inspection or official confirmation may be required.
Think it may be OPM?
Report Suspected OPM
Suspected Oak Processionary Moth sightings should be reported through TreeAlert, the official tree pest and disease reporting service. This is an external official service and opens in a new tab.
Sending us photographs does not replace official TreeAlert reporting.
