How Fleas Can Become Lice
Dogs, cats and other warm-blooded mammals are susceptible to lice infestations. Lice are parasitic insects that live on warm, hairy areas of the body. They can grow up to 4.5 millimeters in length, and are oval or flat in shape. They are dark gray or reddish brown in color. Their eggs are white or tan, and they are also round and flat. Some are symbiotic scavengers, while others are blood parasites. If you think your pet is suffering from lice, make sure to treat all of your pets immediately.
The bites of fleas on humans usually appear in irregular clusters with an erythematous ring around the central bite. They can also cause chronic urticaria, a painful condition characterized by intense itching. The bites are typically concentrated on the lower body, especially the feet and legs. Tight clothing can also be a sign of flea infestation. The marks are often accompanied by red or green discharge, which indicates that the fleas are feeding on blood.
To prevent further infestations, take measures to eliminate the breeding grounds of fleas. Wash bedding, toys and the areas where your pet rests and sits, and make sure that you clean your house and pet grooming tools thoroughly. Insecticides such as Fipronil, imidcloprid and selamectin are effective for controlling fleas. You can also apply topical permethrin, which is not toxic to humans.
