Cuterebra, or rodent bots, is a genus of flies that attack rodents and similar animals. All ages and sexes of cats can be affected as long as the individual has access to the outdoors. Hay aproximadamente 150 especies conocidas en el mundo, llamadas vulgarmente reznos.Producen miasis, que causa grandes pérdidas económicas en el ganado doméstico.
Cuterebra larvae are opportunistic parasites of dogs, cats, and ferrets. Flies are usually host- and site-specific relative to their life cycle.

Take a look at what botflies and warbles are and how they affect cats.

Cuterebra are larger than bot flies and pose serious danger to your kitten. The Cuterebra, or botfly, is an almost 1 inch-long parasite, which needs a small mammal to complete its life cycle. The larva, because of its spines, can pose an extremely painful subepidermal condition. TIL a huge Cuterebra botfly larva was extracted from the tiny nostril of an eight-week-old kitten in North Carolina, USA. Feline botfly infestations are quite common.

Los éstridos (Oestridae) son una familia de dípteros braquíceros especializados en un modo de vida endoparásito dentro de los tejidos de animales vivos, incluyendo los vertebrados y el ser humano.

Pets can contract cuterebra in their larval stage—often called "warbles"—when chasing and hunting small rodents and digging or sniffing near a rodent's den. Larger burrows under your kitten's skin may indicate cuterebra infestation. However, the eggs or hatched larvae can stick onto a dog or cat if they pass by. The larvae then migrate to a subcutaneous (under the skin) spot on the body where they can make a tiny opening through the skin for breathing.

The eggs hatch into larvae and invade the dog or cat through the mouth, nasal passages, or an external wound. Take your kitten to the vet immediately. The authors discuss the epidemiology, life-cycle, and diagnosis of non-tropical botfly infection. A cuterebra is the larval stage of the bot fly, which is found in most regions of North America. Most cases in North America occur in the late summer/early fall. Pet owners usually notice these revolting creatures as a new bump on the skin of their dog or cat. Do not attempt to remove cuterebra larvae yourself. The human botfly occasionally uses humans to host its larvae. Reported is a case of myiasis from Cuterebra botfly larvae in a man from northern New York with no tropical travel. The botfly will react instantly by poking out of the hole. Bot flies are large, non-feeding flies and they tend to target small mammals (mostly rodents, including rabbits) as a host for their larvae. The fastest way to remove a botfly is by putting a generous amount of iodine in the hole. Your cat or dog passes by the area, maybe sniffing out a mouse, and picks up the eggs on her coat.
