“Sand flea” refers not to an insect, but, in this article, to a small 10-legged crustacean also called a sand crab or mole crab, among other names. It is used as bait in saltwater fishing for species such as pompano, redfish, and sheepshead. [1]

  1. Sand flea eggs are orange in color; many fishermen believe these eggs are what attract fish to eat sand fleas. They therefore like to thread orange plastic beads on their line before attaching the hook.
    • Small fluorescent orange bobbers can serve the same purpose as the beads, with the added benefit of keeping the bait just off the bottom.
  2. If you like to fish with light line (10 to 15 pound test/5 to 7 kg class), use a heavier monofilament leader (25 pound test/12 kg class) of about 18 inches (45 cm). You can attach a snap swivel to the line to make it easier to change hooks/lures.
    • You may also want to use a small split shot for added casting weight.

  3. Some fishermen use only a small split shot for added casting weight, while others use sinkers of up to 4 ounces (114 g), depending on where they’re fishing and what species they’re after.
  4. There are two styles of hook commonly used for hooking sand fleas:
    • Pompano fishermen favor the Kahle hook, which features a wide, round bend that aims the hook point back toward the middle of the hook shaft. Other circular style hooks can work equally well.
    • Sheepshead fishermen prefer to use a long-shafted hook, typically about size 1.
  5. Thread the point up through the body above the telson (spade-like tail section) and belly sac toward the head, making sure the crustacean can disperse its eggs as you retrieve it. [2] Ideally, the hook will be run through at enough of an angle so the crustacean will be pulled to the side when you retrieve the bait.
    • Some fishermen prefer to push the barb through the shell, while other fishermen prefer to poke only the hook point through the shell. Lightly hooking the sand flea this way makes it less likely to hang up on seaweed or rocks.
    • Some fishermen prefer to remove the sand flea’s hard outer shell altogether.

  1. This exposes the areas sand fleas inhabit.
  2. The V-marks are places where sand fleas have dug themselves in. [3] You may also be able to see a few sand fleas in the process of burying themselves.
  3. The easiest way to do this is with your hands, a sand shovel, or a sand rake, but some fishermen instead put out a thin net where the sand fleas are, kick the sand to loosen it, then let the tide sweep the dislodged sand fleas into the net.

Sand Flea Storage

  1. Sand fleas need enough moisture to keep their gills wet, which is why you use moist sand. You do not want to submerge them in water, however, as they will drown.
    • If the weather is especially hot, cover the moist sand with a damp cloth. You may also want to cover the cloth with ice chips to keep the cloth and sand beneath cool.
  2. Sand fleas will keep 3 to 4 days in a bucket of moist sand, but during that time, they do produce a yellow-colored waste that must be removed to keep them from suffocating.
  3. If you can’t readily find sand fleas, or you find more than you can use during a single outing, you may want to freeze and store sand fleas for future use. To do this, first boil the fleas and then freeze them. Frozen sand fleas will keep 3 to 4 months.

    What is the best thing I can use for catching sand fleas?

    Sand fleas can be identified by small bumps and v-shapes, so once you've spotted a colony, grab a big handful of sand and set it on a bucket lid. Sift through the sand for sand fleas, then collect them in your bucket — it's that simple!

      Tips

      • While fishing with sand fleas, you can also fish the area with jigs colored the same color as sand flea eggs, which are orange, or a shade of pink similar to the egg color. Many pompano fishermen believe the color of the sand flea’s eggs attracts fish to the sand flea. [4]
      • Keep your hooks sharp when fishing with live sand fleas. Fish will usually strike the bait such that they will impale the hook point in their mouths; you don’t need to set the hook. (If you do, you may actually take the bait away from the fish.)
      • If you prefer an artificial substitute for sand fleas, you can use an artificial lure molded to resemble a sand flea. Hook and fish it the same way as you would a natural sand flea.

      Warnings

      • “Sand flea” can also refer to a parasitic crustacean found in the North Pacific that can exist well away from the shoreline and be brought into houses by hitchhiking on pets and other animals. [5] This kind of sand flea is not intended to be used as bait.
      • The name “sand flea” as used here refers to crustaceans of the genus ‘’Emerita’’ belonging to the suborder ‘’Anomura.’’ “Sand flea” can also refer to a shrimp-like crustacean of the family ‘’Talitridae’’ or to an insect more properly called the sand fly. [6]
