Overview

Sand fleas (Emerita talpoida) are small crustaceans that burrow in the sand in the wave wash zone. They're not actually fleas but got the name from their jumping motion. Pompano, kingfish, and other surf species actively seek them out. Collecting sand fleas is part of the surf fishing tradition.

Frequently Asked Questions

How do I find sand fleas?

Walk the wash zone and watch for V-shapes in the sand as waves recede. Dig quickly with your hands or a rake. They burrow fast.

Do I need a sand flea rake?

It helps but isn't required. A rake with mesh bottom lets sand fall through while keeping sand fleas. Hands work fine for small quantities.

Are sand fleas always available?

They're seasonal. Peak abundance is late summer through fall. Winter they migrate offshore. Spring they return gradually.
