Are Fleas and Lice Related?
WouterWhile fleas and lice are not contagious to humans, some people are allergic to flea saliva and can develop hives. In severe cases, a person can also develop vigorous head scratching, which can lead to infection or skin breakage. However, fleas and lice can be treated safely. Insect repellents can be applied to the head and can keep fleas away for several hours. Other solutions include spraying insecticides in corners and cracks of the house.
Both cats and dogs can become infested with fleas. These insects feed on the blood of warm-blooded mammals. They bite humans, dogs, and cats. While people are not contagious, lice are easily transmitted from human to human in public places. Furthermore, pets with fleas or lice often have poor health and nutrition.
Fleas reproduce quickly, often within a day or two of choosing a host. Their eggs can easily be transferred to other people, pets, or furniture. These eggs can live in a dog’s hair and fall onto the floor or other areas where the dog lies. In addition to direct contact, the eggs can also survive for several weeks without being disturbed.
While both species of lice and fleas are tiny winged parasites, they are quite different. While fleas are usually found on the head of an animal, lice live on the body and are found in the pubic area. Both types of insects can cause annoyance to humans.
