Mosquitoes become infected with tiny immature forms of the heartworm, called microfilariae, when they bite an infected animal. Inside the mosquito, the microfilariae develop into larvae. When an infected mosquito bites a new animal, these larvae enter into the new animal's body causes. Heartworm preventive medications kill the larvae, thus preventing them from maturing into adult heartworms. If left untreated, heartworm disease usually causes death.
