The Forestry Commission may issue you with a Statutory Plant Health Notice (SPHN) asking you to take action.
Removing nests and caterpillars is a hazardous operation. We therefore recommend that a professional does this work. You can find a professional on the Arboricultural Association website. They may spray the trees with an approved bio-pesticide or insecticide.
