Rabbit flea is usually parasitic on the animal or human body, and absorbs the blood of the host for a long time. Keeping pets at home will increase the risk of rabbit flea infestation, because this parasite often parasitizes the pet first. Rabbit flea can spread diseases, and can easily cause allergic dermatitis, posing a threat to human health. After the parasite, people will obviously feel itching, so it can be quickly removed, and the itching and red bite marks will slowly disappear.
