What is the most common ectoparasite found in rodent colonies?

Mites are recognized as the most common ectoparasite in rodent colonies due to their ability to reproduce quickly and their affinity for living in the fur and skin of rodents. Some specific species of mites, such as the fur mite and the hair follicle mite, can cause significant health issues in rodent populations, including skin irritation, hair loss, and secondary infections, which may lead to decreased animal welfare and impact research outcomes.

Rodents can harbor mites with little notice as many infestations can remain asymptomatic until they become severe, which makes routine monitoring and control measures essential in laboratory settings. Understanding the life cycle and impact of mites is crucial for maintaining a healthy rodent colony, which supports the validity of research conducted using these animals.

While other ectoparasites, such as fleas, ticks, and bedbugs, can indeed affect animals, their occurrence in rodent colonies is notably less common compared to mites. This further solidifies the recognition of mites as the predominant ectoparasitic threat in such environments.
