Sightings of Brown-tail Moth caterpillars at Ventnor have been reported to the council.
Following the reports, the council has treated public sites such as the paddling pool in Ventnor to remove the creatures, whose hairs can break off as barbs, causing skin irritation and breathing difficulties.
“We are liaising with Ventnor Town Council to manage the annual influx of this particular young insect. I would remind the public that the hairs on Brown-tail Moth caterpillars can cause skin and eye irritation, particularly in children, so it is important to avoid handling them,” said Lee Matthews, recreation and public spaces manager for the Isle of Wight Council.
“If you are unfortunate enough to be affected, you can expect a rash together with irritation similar to a severe nettle rash. Because the hairs can become airborne some people may experience symptoms affecting their eyes and breathing similar to hay fever.”
Normally this will give a few hours of localised discomfort. Washing the affected area with water and the application of calamine lotion on the skin may ease the itching. The hairs may also worsen symptoms of asthma for some people.
You should seek medical advice from your pharmacist or GP if symptoms do not settle down within a few hours.
The caterpillars become active in the spring. During March, caterpillars can be found in their winter ‘tents’. By April the caterpillars begin to emerge en masse from their tents and start to feed.
They gradually move further away from their winter tents during May until they become solitary. The creatures spin a cocoon and pupate, with adult moths emerging in July/August, ready to mate. Females lay eggs near the tip of shrub branches and then they spin a tent at the end of the shoots in readiness for winter.
