Fleas do not affect humans the same way they do dogs and cats. However, a bad infestation in the home can lead to flea bites on humans, which are often painful and embarrassing. In some instances, a flea bite can even transmit a very serious illness. To protect yourself and your loved ones, here’s what you should know about fleas to manage and prevent infestations in the home.
Fleas prefer pets, such as dogs and cats, when seeking sustenance, but they will also bite humans. This typically occurs when a human poses the best option for a meal. Fleas can live in pet bedding and other types of fabric throughout the home. Because they breed so quickly, a home may become infested in a short period of time.
Flea bites cause tiny red spots on the skin, often in clusters of three and four. Flea bites can also appear in a line.
Most people only experience mild irritation with flea bites, but the insects can sometimes transmit more serious illnesses. Flea-borne spotted fever and murine typhus are caused by bacteria that infects fleas and is passed to humans via flea bites.
Fleas also cause an allergic reaction in some. This can lead to inflammation around the bite, as well as the appearance of rashes and hives. In rare instances, an allergic reaction caused by a flea bite may result in:
Incessant scratching of flea bites may also cause an infection, which requires medical attention.
To avoid scratching flea bites, apply a topical ointment with cortisol to control itching and inflammation. Calamine lotion is also effective at relieving itching associated with flea bites.
If you have pets, apply topical flea treatments to keep the insects out of your home. Also, launder pet bedding with soap and hot water to kill any existing fleas.
