Ornithonyssus bacoti, commonly known as the tropical rat mite, is a parasitic mite that primarily infests rats but can also bite humans when rodent hosts are unavailable or nearby. These mites do not live on humans permanently but feed on blood, causing skin irritation and discomfort. Infestations are often associated with rodent populations in buildings, especially in urban areas where rats are prevalent.
When tropical rat mites bite humans, they cause small, itchy red welts that can lead to intense itching and, in some cases, secondary infections if scratched excessively. Bites are usually found on exposed skin, especially at night when the mites are most active. The psychological impact of an infestation can also be significant, as people may experience anxiety and insomnia due to the persistent itching and discomfort.
Controlling Ornithonyssus bacoti infestations requires addressing the root cause: rodent control. Eliminating rodents from the area, sealing entry points, and ensuring proper sanitation are essential steps. In heavily infested areas, insecticides may also be used. Treating the skin irritation in humans involves topical anti-itch creams and antihistamines to reduce discomfort. Preventing rodent infestations and maintaining clean living spaces are key to reducing the risk of mite-related irritation.
