Beach visitors in Skegness are being urged to avoid touching brown-tail moth caterpillars spotted along coastal paths and dunes.
The caterpillars, common at this time of year, have tiny barbed hairs containing toxins that can trigger rashes or blisters on contact.
Signs have been placed near popular walking areas including Princess Parade Car Park, Lagoon Walk, and the Dunes, reminding people that even brushing against these hairs can cause severe nettle-like irritation.
Council teams are monitoring the situation, while wildlife experts advise keeping away from the caterpillars and their webs to avoid discomfort during seaside trips.
