"Researchers approached us saying that they had heard about oak processionary moth and had been told we are the experts," said London Borough of Richmond upon Thames head of parks David Allister. "We said we are not necessarily experts but we've had experience of the pest."
One Show producers could not be contacted, but Allister said: "Featuring on the show would make the issue national - everyone watches it at some stage."
Richmond teamed up with Bartlett Tree Experts recently for an annual blitz on increasingly virulent attacks of oak processionary moth (HW, 5 May). Tree gangs sprayed branches and trunks to try and control the moth.
Thaumetopoea processionea first appeared in London in 2006 and Richmond has spent £200,000 fighting the moth over four years.
It is believed to have been imported on trees from Holland for a housing scheme in Kew and around 1,800 trees have been treated to date.
