How can I protect myself from sand fleas? - in detail
Sand fleas, also known as beach fleas or sand hoppers, are tiny crustaceans that bite exposed skin when they mistake it for a host. Bites cause itching, redness, and occasionally small pustules. The insects thrive in moist, sandy environments, especially after high tide or in areas with decaying organic matter.
Wear tightly woven, long‑sleeved shirts, long trousers, and socks made of synthetic fibers that do not retain moisture. Tuck clothing into footwear to eliminate gaps. Apply insect repellent containing at least 20 % DEET, picaridin, or IR3535 to all exposed areas; reapply according to product instructions, particularly after swimming or sweating. Avoid walking barefoot; use water‑resistant sandals or shoes with closed toes.
Limit exposure during peak activity periods, typically early morning and late afternoon when sand temperature is lower. Rinse feet and legs with fresh water after leaving the beach to wash away any insects that may have attached. Dry the skin thoroughly before dressing to prevent the fleas from moving into clothing folds.
Maintain the beach area by shoveling away debris, removing seaweed, and allowing sand to dry between visits. In campsites, keep sleeping mats and towels off the sand, using raised platforms or hammocks. Store clothing in sealed bags when not in use.
If a bite occurs, clean the site with mild soap and cool water, then apply a topical antihistamine or corticosteroid cream to reduce inflammation. Over‑the‑counter pain relievers may alleviate discomfort. Monitor for signs of infection, such as increasing redness, swelling, or pus, and seek medical attention if they develop.
