Mosquito Mosquitoes!
With the help of Malaria Malaria, the mosquito mosquitoes will spread a fatal disease to each of the mosquitoes, thus killing them!
Step 3: Profit!!!
They are working on breeding mosquitoes that can’t carry the malaria virus and releasing them to spread that gene, that way the mosquitoes still survive (important food source for some animals) and their bites wont cause malaria.
