The answer to 'flea droppings' is that they are a common sign of a flea infestation in your home. Flea droppings, also known as 'flea dirt', are small, dark specks that resemble ground pepper. They are the digested blood of the host animal (usually your pet) that the fleas have fed on.
Seeing flea droppings is an indication that you have a flea problem that needs to be addressed. Fleas can cause itchy bites, skin irritation, and even transmit diseases to both pets and humans. To get rid of fleas, you'll need to treat your home and pets with appropriate insecticides and thoroughly clean carpets, bedding, and other areas where fleas may be hiding.
