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 in Sulham Woods in Pangbourne near Reading. Two spots were sprayed today, but the operation has been delayed a number of times this year, because of the weather.

However, the use of chemicals has concerned environmental groups - who say other creatures, not just the caterpillars and moths, will be harmed. Cary Johnston reports.
