Fleas are common parasites that infest pets and their bedding, transmitting diseases like Bartonella, Rickettsia, and tapeworms. They reproduce rapidly, causing re-infestation and increasing the risk of severe allergic reactions and anemia, especially in vulnerable pets. If left untreated, severe flea infestations can lead to life-threatening conditions such as flea anemia, particularly in small or young animals.

Mites are microscopic parasites that can infest pets and their bedding, leading to skin conditions like mange. Sarcoptic mange, caused by Sarcoptes scabiei, is highly contagious and results in intense itching, hair loss, and skin infections. These mites burrow into the skin, causing discomfort and potential secondary infections. If left untreated, this can lead to a weakened immune system, systemic illness, and, in severe cases, death.

Ticks are dangerous parasites that infest pets and their bedding, transmitting serious diseases like Lyme disease, ehrlichiosis, and babesiosis. These parasites create a high-risk environment for re-infestation and disease transmission. Lyme disease, in particular, can cause severe long-term health issues like kidney failure and neurological disorders, potentially leading to death if not treated promptly. Regular sterilization of bedding and preventive care are essential to protect pets from these life-threatening parasites.
