Mosquitoes are weak fliers
Many of the mosquito species only weigh about 2.5 milligrams and generally do not fly above 25 feet. This is the main reason why mosquitoes are considered as weak fliers in the flying pest category.
One of the best ways to keep mosquitoes away from you is by set-up the fan on high speed to make them not be able to land securely on you due to the wind that fan blows. Furthermore, the fan also reduces body heat and sweat, which become the sensory information for them to locate their prey.
