Don’t panic: Sea lice are common at Mid-Atlantic beaches

Earlier this week, some swimmers in Virginia Beach felt the sting and itching sensation of being bitten by sea lice.

The term “sea louse” doesn’t describe a single species, but is actually a family of tiny, translucent crustaceans — locally, they’re often blue crab larvae or jellyfish larvae — but many possess pincers large enough to irritate someone’s skin.

One Virginia Beach swimmer Thursday documented the sea lice he discovered in his bathing suit pocket:

Last summer, Ocean City had a brief but significant struggle with sea lice.

They’re in local beaches every year to some extent, with water temperatures and sea current direction playing a large role in determining whether the sea lice season is a boom or bust.

“If it does happen to you, where you start itching really bad within your suit, the best thing you can do is get to your hotel room, take that suit off, get it rinsed out,” said Tom Gill, of the Virginia Beach Lifesaving Service, to WTKR, in Norfolk, Virginia.

Gill said cooler waters by Friday seems to have alleviated the problem in Virginia Beach.

And, despite the “ewww” factor and temporary discomfort of a rash after being stung, there is, believe it or not, an upside to sea lice.

“Anyone who enjoys eating steamed blue crabs should welcome the sea lice,” said Chris Witherspoon, with the Virginia Aquarium.

“Around one out of every 500,000 blue crab eggs will become an adult crab — without sea lice appearing along shore and in the Bay each summer, there would be no blue crabs here.”
