Yes, humans can get fleas from dogs, but they can't live on us long-term, and they actually prefer furry, four-legged hosts.
Here's what to know about flea bites, health risks, and keeping your family protected. (For the full picture on how dogs pick up fleas in the first place, see our guide to fleas on dogs.)
Can fleas live on humans?
Fleas do not live on humans. While they can occasionally bite, fleas require thick fur to burrow into, hide, and lay eggs. That's why, of the roughly 88 flea species found in Australia, only a handful bother with humans at all, and almost always the cat flea (Ctenocephalides felis), which happily feeds on cats, dogs, and occasionally us.
Fleas are excellent jumpers, launching themselves onto a new host from up to 30cm away. So if your dog's has a current flea infestation, don't be surprised if the occasional flea jumps on your ankles when you are patting them.
What do flea bites look like on humans?
Flea bites show up as small, intensely itchy red bumps, usually clustered on the legs and feet, since fleas aren't great climbers and tend to bite wherever they land first.
The bumps typically appear within about half an hour of the bite, and some people develop a stronger, more inflamed reaction if they're sensitive to flea saliva.
What health risks do fleas pose to humans?
For most people, flea bites are an itchy inconvenience rather than a genuine health threat, but there are a few risks worth knowing about.
Allergic reactions are the most common concern. Flea allergy dermatitis causes intense itching, redness and hives in sensitive individuals, whether the bite came from a flea living on your pet or one that's hopped onto you directly from the environment.
Secondary infections can follow, especially if bites are scratched repeatedly and the skin breaks.
Fleas can transmit some rare diseases in Australia, but they are uncommon. Some fleas carry the bacteria Rickettsia felis, which can cause flea-borne spotted fever, also known as cat-flea typhus, with symptoms including fever, fatigue, headache and a skin rash. Fleas can also carry the tapeworm Dipylidium caninum, which may infect humans, usually children, if a flea is accidentally swallowed.
If you or your child develop a persistent rash, fever, or other symptoms after flea exposure, it is best to see your doctor.
Vet tip: If you're finding bites on your ankles but haven't seen fleas on your pet, it is best to treat them for fleas on suspicion. Fleas are experts at hiding, and a few bites on you can mean a much bigger population living in your dog's coat.
How do you protect yourself from fleas?
The most effective way to stop fleas biting you is to stop them living on your pet in the first place. Consistent protection with a flea preventative, breaks the flea lifecycle and protects your dog, and in doing so your house and family. Every pet in the home needs to be treated, even indoor cats, since a single untreated animal can keep the whole infestation going.
If fleas have already made themselves at home in your carpets and bedding, treating your pet alone may not be enough. You will need to treat the environment too, so check our guide on how to get rid of fleas on dogs for cleaning, vacuuming and treatment steps.

Bottom line
Humans can pick up the occasional flea bite from a dog with fleas, but we're not a flea's host of choice, and there's no need to panic.
Keep your pets on regular flea prevention, treat every animal in the household, and see your GP if bites become infected or you notice symptoms beyond local itching.
