Getting rid of sand fleas outside is nearly impossible because they bury themselves in sand. Infestations in homes should be handled by professionals, who are likely to use bug bombs that release toxic gases to kill the fleas. However, sand flea infestations in the home are rare because the crustaceans prefer to live near large bodies of water. Also, sand fleas don't travel very far from where they are born.
Sand fleas are often believed to be related to the house flea. However, sand fleas are crustaceans, not insects. This means that they are part of the same family that lobsters, crabs and shrimp belong to. Just like the common house flea, a bite from a sand flea injects anti-coagulants into the victim, which allows the fleas to suck out the blood that they require to lay eggs. The bite from a sand flea is much more painful than a bite from a house flea.
Due to the bacteria that sand fleas carry with them, it is possible to develop a fever or catch a disease from sand flea bites. After being bitten by a sand flea, the victim should avoid the temptation to scratch because this increases the risk of the bite becoming infected or turning into a rash. Sand fleas often live in large groups, and they make a high-pitched whining sound. If the group is large enough, this sound can be heard by the average person.
