Mosquitoes transfer Heartworms by ingesting baby Heartworms and then biting your pet and leaving behind the worms to mature and become adult Heartworms. The United States as a whole experienced above average precipitation and seasonal temperatures in 2016, leading to perfect conditions for breeding the mosquitoes that transmit heartworm disease.
A variety of Heartworm preventatives are available through J.M. Pet Vet and J.M. Pet Resort. These preventatives do not keep your pet from getting Heartworms from mosquitoes. Instead, they work by killing the baby Heartworms that mosquitoes leave behind before the worms can mature and infest your pet.
