The good knight mosquito repelent is very harmfull to health. They not totaly kill the mosquito but spoile the environment.
One night I am started good knight and all family member are sleeped after some time my father woke up then feel very uncomfortable doctor come and check and tell not serious problem. After this incident in my home not use good knight and my father problen not created after.
Plz do not use if in your home BP patient.
