Fleas primarily target animals, especially pets like dogs and cats, but they can indeed affect humans as well. While fleas do not live on humans, they can bite us, leading to itchy, red welts on the skin. This is especially common in areas where pets are present. Additionally, fleas can transmit diseases, although this is more common in animals. To protect both your pets and yourself, it's important to treat your pets for fleas regularly and maintain a clean environment. If you notice flea bites on yourself or your pets, consider consulting a veterinarian for effective flea control methods.
