This is why cases are frequently reported among travelers or individuals living in rural, tropical regions where proper screening might be less common, allowing the infected insects to land and feed unnoticed. Alternative Routes of Infection While the vector method is the most common pathway, there are instances where botflies get into humans through more direct, though still unintentional, means.

Symptoms and Early Detection Once the larvae have successfully entered the human dermis, they begin the process of maturation, which leads to the symptoms that alert the host to the infection. In Central and South America, where Dermatobia hominis is most prevalent, the primary vectors are often mosquitoes from the genus Aedes and Psorophora, as well as stable flies.
If a female botfly deposits eggs on fabric and that fabric then comes into contact with a warm area of human skin—such as the armpit or groin—the larvae can emerge and penetrate the skin directly. Common Vectors and Environmental Triggers Understanding the insect vectors is central to answering how do botflies get into humans , as these arthropods are the unwitting chauffeurs of the botfly lifecycle.

Unlike typical flies that are merely nuisances, botflies have evolved a complex lifecycle that hinges on exploiting other animals, including humans, as incubators for their developing young. One documented route involves the accidental introduction of eggs via contaminated clothing, bedding, or towels.
