What Are Leopard Gecko Mites?
External mites can occasionally infest leopard geckos, feeding on their blood and causing irritation, stress, and, in severe cases, anemia. Prompt treatment helps prevent the infestation from spreading. Mites spread rapidly between enclosures and should be addressed as soon as they're identified.
How to Identify Mites on a Leopard Gecko
Mites are tiny — about the size of a poppy seed — and appear dark red, brown, or black. They move. Common signs include:
- Tiny moving specks on your gecko's skin
- Irritation around the vent, eyes, and skin folds
- Mites hiding around enclosure seams, corners, and under decor
- Excessive rubbing against enclosure surfaces or decor
- Restlessness and visible discomfort
- Lethargy and reduced appetite in heavier infestations
- Visible mites on your hands after handling
Quick Rule: If you see tiny moving specks on your gecko or around enclosure seams, assume mites until proven otherwise and act immediately.
How to Treat Leopard Gecko Mites
Effective treatment requires addressing both the gecko and the enclosure simultaneously. Treating one without the other guarantees reinfestation.
Step 1: Isolate the Gecko
Move your leopard gecko to a temporary quarantine tub with paper towel substrate, a water dish, and a simple hide. Keep it simple so mites have nowhere to hide.
Step 2: Treat the Gecko
Use a mite treatment specifically labeled for reptiles and follow the manufacturer's directions exactly. Do not use products containing permethrin or DEET — these are toxic to reptiles. A shallow soak may help loosen debris and make mites easier to spot, but it should not replace an appropriate reptile-safe treatment.
Step 3: Strip and Disinfect the Enclosure
- Remove and discard all substrate.
- Remove and discard or thoroughly disinfect all porous decor.
- Scrub the enclosure with a reptile-safe disinfectant, paying attention to corners and seams.
- Allow everything to dry completely before reassembling.
- Use paper towels as substrate during treatment so mites are easy to spot.
Step 4: Treat All Reptiles in Your Collection
Inspect every enclosure carefully. Mites spread easily between collections — even animals without visible mites should be monitored closely.
Step 5: Repeat
Most mite treatments do not kill eggs. Repeat the full treatment cycle in 7–10 days to catch newly hatched mites before they reproduce.
What Not to Do
- Don't use dog or cat flea products — most are fatal to reptiles.
- Don't use products containing permethrin, pyrethrin, or DEET.
- Don't treat only the gecko and ignore the enclosure.
- Don't handle other reptiles after handling an infested gecko without washing hands and changing clothes.
- Don't ignore mites — infestations grow exponentially.
How to Prevent Mites
- Quarantine all new reptiles for a minimum of 60–90 days before introducing them to your collection. New reptiles remain the most common source of mite infestations.
- Wild-caught feeder insects or contaminated enclosure furnishings can occasionally introduce external parasites — source feeders from reputable suppliers and inspect used equipment before introducing it to your collection.
- Inspect new geckos thoroughly before purchase — check skin folds, around the vent, and between the toes.
- Wash hands between handling different animals.
- Inspect your gecko regularly during routine handling — early detection makes treatment far easier.
FAQ
Can leopard gecko mites infest my home?
Reptile mites prefer reptile hosts and don't establish permanent infestations on humans, but they can bite and temporarily survive off the host. Treat promptly to prevent spreading to other enclosures.
Where do mites come from?
Most infestations are introduced through new reptiles, contaminated substrate, used equipment, or contact with infested animals at reptile shows or pet stores. Quarantine is your best defense.
