Fleas generally cannot live in human hair. While most species prefer to live on the furs of animals, they can use humans as temporary vectors. In such cases, fleas can infest and bite humans. You may get infected if there is a serious case of flea infestation in your environment. Fleas can transmit various diseases and cause allergies and must be treated promptly.

There also are different types of fleas you might come into contact with, especially if you have pets. Being aware of them can help you take effective control and prevention measures. The four common types of fleas are (1):

  • Cat flea (Ctenocephalides felis): Commonly found on cats, but can also infect dogs and other animals
  • Dog flea (Ctenocephalides canis): Primarily affects dogs, but can also feed on other animals

  • Rat flea (Xenopsylla cheopis): Infests rats and is known for transmitting serious diseases like the bubonic plague

  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.
