Areas Affected by OPM
Originally native to the Mediterranean regions of Europe, the oak processionary moth continues to spread and is now well established in a number of countries including Germany, Belgium, and Holland. The caterpillars were first found in London in 2006 and government studies show the pest spreading on an annual basis.
West and Southwest London are most severely affected with OPM-infested trees confirmed in the following boroughs: Barnet, Brent, Bromley, Camden, Croydon, Guildford, Ealing, Elmbridge, Epsom & Ewell, Hackney, Hammersmith & Fulham, Hounslow, Islington, Kensington & Chelsea, Kingston, Lambeth, Lewisham, Merton, Mole Valley, Newham, Richmond, Southwark, Spelthorne, Tower Hamlet, Waltham Forrest, Wandsworth, Watford and Westminster.
