Removing A Massive Botfly Maggot From A Tiny Cat

Botfly is the North American rabbit or rodent botfly. The adult botfly puts its eggs near or in the opening of rodent and rabbit burrows. After hatching, the Botfly, which typically infect rodents and rabbits, enters the host’s body through an opening such as the nose or mouth, or through a skin wound. A dog or cat is often accidentally infected with the larvae as they investigate rabbit or rodent or burrows (holes).

After several days, the Botfly migrate to the tissues beneath the skin where they encyst and continue their development. Larval development within the host may last from nineteen to thirty eight days in small rodents and from fifty five to sixty days in jackrabbits. After leaving the host, the larva develops into a pupa (immobile cocoon-like stage) in loose soil, debris or forest duff. The pupation period may be as long as 7 to 11 months or as short as 28 days, depending on the environmental temperature and botfly species.
