Snake Mites
What is it?
Snake mites (Ophionyssus natricis) are tiny blood-sucking parasites that live on snakes and in their enclosures. Heavy infestations can cause anemia, and mites can spread infections like IBD.
What signs should I watch for?
Signs to watch for include tiny black or red moving dots, often around the eyes and under scales; soaking in the water bowl more than usual; rubbing, irritability, or restlessness; and raised scales or abnormal shedding.
How is it diagnosed and treated?
Mites are usually visible on exam. Treatment involves reptile-safe antiparasitic therapy and a thorough clean of the enclosure and all furnishings; mites hide in crevices and around tank lids.
Can it be prevented, and what's the outlook?
- Quarantine all new snakes and inspect them closely.
- Repeat treatments are often needed to break the life cycle.
