Flea (Ctenocephalides felis)

Ctenocephalides felis, commonly known as the cat flea, is one of the most prevalent flea species affecting domestic animals and occasionally humans. Despite its name, the cat flea infests not only cats but also dogs, other mammals, and birds. This tiny yet troublesome pest can cause significant discomfort and health issues for pets and their owners.

Cat fleas are small, wingless insects, measuring about 1 to 3 millimetres in length. They have a flattened, reddish-brown body that allows them to move easily through the fur of their hosts. Fleas are equipped with powerful legs that enable them to jump great distances relative to their size, facilitating their movement between hosts and the environment.

Cat fleas are obligate ectoparasites, meaning they depend on a host for survival and reproduction. They feed on the blood of their host, with both adult males and females requiring blood meals to reproduce. The life cycle of the cat flea includes four stages: egg, larva, pupa, and adult. Under optimal conditions, this cycle can be completed in as little as two to three weeks.

1. Eggs: Female fleas lay eggs on the host, which then fall off into the environment, such as bedding, carpets, and furniture. These eggs hatch in about two to twelve days.
2. Larvae: The larvae are tiny, worm-like creatures that feed on organic debris and the faeces of adult fleas. This stage lasts about one to two weeks.
3. Pupae: Larvae spin cocoons and enter the pupal stage, where they develop into adults. The pupal stage can last from a few days to several months, depending on environmental conditions.
4. Adults: Adult fleas emerge from the pupae when they sense the presence of a host, such as through vibrations, heat, or carbon dioxide. They immediately seek a blood meal to begin the reproductive cycle anew.

Cat fleas can transmit several diseases and parasites, including:

• Tapeworms: Flea larvae can ingest tapeworm eggs, which then develop into adult tapeworms in pets when they groom and swallow infected fleas.
• Bartonellosis: Also known as cat scratch disease, this bacterial infection can be transmitted to humans through flea bites.
• Flea Allergy Dermatitis: Pets can develop severe allergic reactions to flea saliva, leading to intense itching, hair loss, and skin infections.

Signs of a flea infestation include:

• Frequent Scratching: Pets may scratch, bite, or lick themselves excessively.
• Flea Dirt: Small black specks, which are flea faeces, can be found on pets' skin, bedding, or in areas where they rest.
• Visible Fleas: Adult fleas may be seen moving through the fur or on the skin of pets.
• Skin Irritation: Red, inflamed skin and scabs can result from flea bites and allergic reactions.

Effective control and prevention of cat flea infestations involve a combination of treatments for pets and the environment:

• Pet Treatments: Use flea shampoos, spot-on treatments, oral medications, and flea collars to kill and repel fleas on pets.
• Environmental Control: Regularly vacuum carpets, furniture, and pet bedding to remove eggs, larvae, and pupae. Wash pet bedding and use insect growth regulators (IGRs) and residual insecticides in the home to break the flea life cycle.
• Yard Maintenance: Treat outdoor areas where pets spend time with appropriate insecticides and maintain a clean, debris-free yard to reduce flea habitats.
