Mosquitoes are important vectors for both human and veterinary diseases. Pathogens and parasites cause widespread sickness and mortality, as well as a significant negative impact in many countries. Synthetic pesticides are now the standard of protection against these lethal mosquitoes. Synthetic pesticides, on the other hand, have a huge cumulative effect on nature, such as non-target effects, pollution, and so on. As a result, the researchers shifted their focus to a new alternative strategy that would be acceptable for both the environment and public health. The use of bio-insecticides derived from botanical extracts appears to be a potential way of vector control. Many plant extracts contain secondary metabolites, which have stronger insecticidal properties. Similarly, pests are another natural organism that causes enough harm to crops to put the human population at risk. There are numerous pests that are unique to each plant species. We use synthetic insecticides to control pest populations, but this has negative implications such as health risks. As a result, efforts are being made to isolate biological molecules from plant sources, which are both environmentally beneficial and cost effective. In this regard, a variety of medicinal plants have been investigated for pest management since these botanicals offer pesticidal properties. The goal of this review was to assess current research on botanicals as potential insecticides and pesticides in terms of chemical composition and biological activity.
