Bexley residents are being warned to stay alert after sightings across the borough of a moth species that can be dangerous to humans and animals.

The Oak Processionary Moth has been found in Danson Park, East Wickham Open Space, Monks Farm Allotment and Sidcup Place.

The species was first found in London 12 years ago, and is known to have settled in Bromley and Greenwich.

While the moths themselves are not thought to be harmful, the hairs on its caterpillars can cause serious allergic reactions.

Cases of skin rashes, sore throats, breathing difficulties and problems with sight have been reported in humans and animals after contact with the caterpillars

Although the greatest risk period is between May and July, Bexley Council has warned people that they could come into contact with the hairs throughout the year as they are often carried in the wind.

The council has promised action in the problem areas where moths and their caterpillars have been spotted.

The Forestry Commission has arranged for trees to be sprayed and caterpillar nests to be removed, with two treatments taking place in each location to see off the pesky moths.

The first sprayings will take place in mid-April, lasting two to three weeks, with the second scheduled for the end of May.

Signs will be put up to clearly mark which trees are being sprayed at any given time.

Bexley Council has assured park visitors that they will not be at risk from the spraying process.
