Oak processionary moth population exploding in London

Posted by Landscape Juice on September 30, 2014 at 3:26pm

Populations of toxic oak processionary moth (OPM) ‘exploded’ this summer despite control efforts, spreading from west London to as far as Stratford’s Olympic Park.

Children at a school have been affected and arborists at Kew Gardens have developed rashes after being stung by the poisonous hairs shed by the moth’s caterpillars, which appear from late spring to early summer.

The invasive caterpillars feed voraciously on oak leaves. They have no natural predators in England and have established in west London since they were believed to have arrived on oak saplings imported from Holland in 2005.

"I charge on site if need be, or at home first, depending on how long I am at the job, which are mostly half days. I only spend 15 minutes max dringing to/from home so no way I could charge in the van even if I wanted to go down that route. Most…"

So it is not expensive to buy and is lightweight, so easy to handle. One guy I used to work for…"

"Tiller or rotavator, it still the same mud.
Ten ton of the council soil improver from the household recycling mixed in with it would help, don't call it compost because it's not.
Edit- looking at the photo again, make it at least twenty tons."
