Intense scalp itching followed by the appearance of red welts, bumps, or pus-filled blisters (usually on the neck or scalp) can be symptoms of flea bites. Individuals allergic to flea saliva may experience irritation, redness, and scalp inflammation. If the irritation and redness last up to 3 days or more, consult your doctor.

It is difficult to distinguish between human and animal fleas without a microscope or the proper knowledge of their anatomy. Hence, you must treat them if you experience any of the symptoms mentioned above.

  1. It is possible you have pets that could have been infected. Give them a bath with a specially formulated shampoo and a flea comb to get rid of any fleas or ticks. Protect yourself by wearing gloves while bathing your pet. A serious infestation would warrant a veterinarian’s advice for proper treatment.
  2. Wash your pillows, linen, towels, clothes, and other household items. Also wash all your pet beds, toys, and mats.
  3. Disinfect your hats and headgear or accessories by keeping them in sunlight for a few hours. You can even spray tea tree oil or apple cider vinegar to remove any fleas.
  4. Vacuum your carpets, curtains, rugs, and couches. Call pest control if there is a serious infestation.
  5. Clean or close any open garbage spaces around your home as they could be a source of flea infestation too.

Frequently Asked Questions

Will fleas lay eggs in human hair?

No, fleas don’t lay eggs in human hair. Fleas cannot breed living off human blood. They lay eggs in cats, dogs, and other pet animals.

How long do fleas live on humans?

Fleas cannot live long in human hair, and our strands are not thick enough for them.

Will fleas go away on their own?

No. Once fleas find their host animal, they can stay on them, lay eggs, and cause an infestation.

Where do fleas hide in the bedroom?

Fleas need blood to survive. They will be found on animals or humans. But check your pillowcases, sheets, and mattress – as they can survive on inanimate objects for about 24-48 hours without blood.
