Chemicals sprayed from helicopter to wipe out moths

A cloud of chemicals has been sprayed over parts of Berkshire today to halt the spread of a toxic caterpillar. The Oak Processionary Moth destroys trees and causes severe itching and rashes in humans and animals.

The area affected is Sulham Woods in Pangbourne. Two locations were sprayed today - but the operation has been delayed several times this year because of the weather.
