Oak caterpillar moth danger
SIGHTINGS of a hairy caterpillar that can make humans and pets very unwell must be reported this summer, but people are being urged not to touch them.
England is about to enter its ‘greatest risk period’ when oak processionary moth caterpillars emerge before turning into adult moths. The moths have been previously found in West Berkshire woodland.
Their appearance, usually between mid May and July, can pose a risk to the public and their animals.
The caterpillars should not really be touched under any circumstances.
Oak processionary moths are officially classified as tree pests, having been first identified in London back in 2006.
Since then the creature has spread in much larger numbers and outside the capital to many surrounding counties, particularly in the South East of England.
Alongside their ability to make people and pets feel unwell, the caterpillars have can cause damage to oak trees.
Their desire to feed on several species causes the trees to lose their leaves, affect their growth and lead to them becoming more vulnerable to other stresses like drought.
A Forestry Commission spokesperson said: “To safeguard tree and human health, it is important that members of the public report any suspected sightings.”
How to identify an oak processionary moth caterpillar:
The caterpillar nests are typically dome or teardropshaped and usually around the size of a tennis ball.
The caterpillars, are about 2cm long when fully grown, will have black heads and bodies which are covered in long white hairs.
It is a protein in the hair which will cause itchy rashes, eye, and throat irritations.
Anyone who spots this particular caterpillar in the weeks ahead is asked to report their sighting to the Forestry Commission via the Commission’s Tree Alert portal. Alternatively call 0300 067 4442.
Sightings can also be reported by emailing opm@forestrycommission.gov.uk
Anyone who has come into contact with one of the caterpillars should visit a pharmacist for help with milder reactions or consult a GP for more serious reactions.
If animals have been seriously affected, animal owners should contact their vet for help and treatment.
