  2. Avoid Early or Late Hours: Don’t go to the beach before 10 or 11 in the morning, and don’t wait until it starts to get cool to leave. These hours are the favorite times for these fleas to come out and eat.
  3. Cover Yourself in Repellent: If you know there’s a chance you’ll encounter sand fleas, a repellent should be applied to the entire body. This will also ward off sand fly bites, mosquitoes and bites from other pests.

Some experts recommend not laying on a beach towel or blanket either.

Instead, you should lay on a lounge chair or regular chair. This will keep you out of reach of the fleas and is recommended. If you’ve been bitten on a particular beach before, you may want to follow this advice to ensure that you’re not bitten in the future.

If you’re walking on the beach, you should wear socks or shoes.

The Steam Cleaning MythGreen-white steam cleaning working on floor.

There is a myth going around online that you can steam clean areas where sand fleas are present. But this isn’t quite true. First and foremost, these crustaceans can live in water, and they live on the beach or in the desert where sand is in abundance.

Since this is the case, you can’t use a steam cleaner to kill them.

Sand fleas will not invade your home like a dog or cat flea will. These fleas don’t have any reason to stay in your home, and if you see one in your yard or in your home, there is no cause for concern.

As for steam cleaning the beach or desert, this is just silly misconception where the person is confusing a regular cat or dog flea with sand fleas.
