Due to the fact that Covid-19 disease is spreading rapidly and there are many concerns about the unknown routes of transmission of the virus, which is an special attention and study should be done on the routes of transmission and spread of this disease, so that with the correct and accurate knowledge of the routes of transmission of the disease, the necessary measures can be taken to reduce and control this disease. Some insects such as flies and cockroaches, according to the characteristics of the behavior and biology, as well as contact with human lives, can be potential mechanical vectors of pathogens, especially coronavirus. Although transmission of the coronavirus by different species of insects is being studied by scientists, the transmission of the virus by bloodsucking insects has not been reported or confirmed. only way to prevent it is to get an effective vaccine. For this reason, methods in the case of some insects, such as flies, as mechanical vector, methods of control and removal of vector, including mechanical and physical methods: (placing nets on doors and windows, Ventilators), improving the environment :(correct garbage collection, preventing the accumulation of waste Human and animal), chemical methods: (spraying surfaces and space), etc are effective in Conflict of interest None declared. Acknowledgement Thanks to those who helped us with this study. important and priority issue for the World Health Organization. Therefore, Disease and since there is no definitive cure for the disease and the controlling coronavirus disease.
