Mosquitoes
Mosquitoes are yet another example of how one should never underestimate a threat because of their size. Mosquitoes spread all types of illnesses that reportedly lead to about 830,000 deaths annually like malaria, Zika, Japanese encephalitis and dengue fever. In fact, malaria cost the lives of 445,000 people in 2016 alone. Fortunately, mosquitoes are vulnerable to insecticide. Another great way to avoid attracting them is to get rid of still water on a property where mosquitoes like to lay their eggs.
