Cat fleas are all over the house and require the use of disinfectants and insecticides to drive them away. First, clean the house, isolate the cats, spray the diluted disinfectant in every corner of the house, and then use Spray insecticide in areas where fleas often hang out, and close the door for a day. Many fleas will die. If there are still fleas surviving, it is recommended to do it again every few days.
Tips:
Usually pay attention to environmental hygiene, clean and disinfect regularly, ventilate frequently, and deworm cats on time.
