CHARLESTOWN, R.I. (WLNE) – The Rhode Island Department of Environmental Management (DEM) issued an advisory Wednesday that Atlantic Sea Nettle Jellyfish have been spotted in large numbers in two Charlestown ponds.

The jellyfish have been identified in Ninigret and Green Hill Ponds.

DEM says anyone planning to recreate at these ponds should bring a first aid kit, including a bottle of vinegar and sting spray.

The sting of a Sea Nettle can cause moderate discomfort and itchy swells on the skin. If you are stung, DEM says to:

  • Remove visible tentacles with a gloved hand or a plastic bag
  • Rinse the affected area in vinegar or a commercially available sting spray (or saltwater)
  • Do NOT rinse with freshwater, as this can worsen the sting
  • Apply heat pack or rinse under hot water
  • Use an ice pack and/or hydrocortisone cream to reduce discomfort
  • If symptoms worsen, seek medical attention

DEM says these jellyfish are common in Rhode Island during the summer, though the reason for their high numbers right now is not understood. Their numbers are expected to decline as the season goes on.
