Cat Flea

Updated: Sep 12, 2023

Cat fleas, scientifically known as Ctenocephalides felis, are parasitic insects that primarily infest domestic cats, but they can also affect dogs and other warm-blooded animals, including humans. These tiny, blood-feeding pests are a common and troublesome household pest. Here is a description of cat fleas as pests:

Physical Characteristics:

  • Size: Cat fleas are small, measuring about 1-2 millimeters in length, making them difficult to detect without close examination.

  • Color: They are typically reddish-brown to dark brown in color, with flattened bodies and well-developed legs adapted for jumping.

Habitat and Behavior:

  • Host Parasites: Cat fleas are obligate parasites, meaning they rely on the blood of their host animals to feed and reproduce.

  • Lifecyle: Their life cycle includes four stages: egg, larva, pupa, and adult. Eggs are laid on the host but quickly fall off into the environment, where they develop into larvae and then pupae before emerging as adult fleas.

  • Jumping Ability: Fleas are exceptional jumpers, capable of leaping many times their body length. This ability allows them to easily move between hosts and within the environment.

  • Biting and Feeding: Cat fleas bite their host animals to feed on their blood. Flea bites can be itchy and uncomfortable for both pets and humans, often leading to scratching and skin irritation.

Problems Caused by Cat Fleas:

  • Discomfort: Flea bites can cause itching, redness, and skin irritation in both pets and humans. Pets infested with fleas may scratch excessively and experience hair loss.

  • Allergic Reactions: Some individuals and pets can develop allergies to flea saliva, leading to more severe allergic reactions known as flea allergy dermatitis (FAD).

  • Vector for Disease: While less common, fleas can transmit diseases such as Bartonella (cat-scratch fever) and tapeworms when they feed on infected hosts and then bite humans or pets.

  • Population Explosion: Fleas reproduce rapidly, and a small infestation can quickly become a significant problem if left untreated. Flea eggs, larvae, and pupae can develop in carpets, bedding, and furniture.

Control and Prevention:

  • Pet Care: Regular grooming and use of flea preventatives on pets can help control infestations. Consult with a veterinarian for guidance on suitable flea control products.

  • Environmental Cleaning: Frequent vacuuming and washing pet bedding can help eliminate flea eggs and larvae from the environment.

  • Pest Control Products: In severe infestations, professional pest control services may be necessary to treat both the pet and the indoor environment with appropriate insecticides.

  • Preventive Measures: Year-round preventive measures, even during non-flea seasons, can help keep flea populations in check.
