While some amphipods may become a nuisance to certain homeowners, like the terrestrial amphipods commonly referred to as land shrimp, that’s not the case with sand fleas. According to Texas A&M, sand fleas “generally cause no problems or concerns in urban environments.” Instead, they prefer to stay in their sandy beach environments. For this reason, it’s unlikely that you’d bring a sand flea home with you. Finally, sand fleas are most active during the nighttime, which is not when most beachgoers are visiting the beach, so you might not even come across these hopping crustaceans unless you are digging in the sand or picking up rocks on the beach.
