Quarantining a New Reptile
The most common way an established collection gets mites or parasites is a new animal going straight into the room. Quarantine is unglamorous and it is the cheapest insurance there is.
What quarantine is actually for
It buys observation time. Parasites, mites and early respiratory infections rarely announce themselves on day one, and an expo or shop animal has usually been close to a lot of other animals. Quarantine separates a problem that affects one animal from a problem that affects your whole collection.
How to set it up
Simple and observable. Paper towel or newspaper substrate so stools and mites are visible, a hide, a water bowl, correct heat, and nothing porous. Keep it in a different room if you can. If you cannot, keep it as far from the others as possible and always clean and feed it last, never first.
How long
Longer than feels necessary. Keepers commonly run 30 to 90 days, and the longer end is sensible for an animal of unknown origin or one bought at a show. Parasite life cycles and the slow onset of respiratory signs are what set that window, so cutting it short defeats the purpose.
What to watch for
Weight trend, feeding response, stool consistency, and anything in the water bowl. Tiny dark specks drowned in the water are often the first sign of mites. Bubbles at the nose, open-mouth breathing or clicking are respiratory signs and need a vet rather than more waiting.
Common questions
How long should I quarantine a new reptile?
Commonly 30 to 90 days, with the longer end for animals of unknown origin or bought at a show. The window exists because parasite cycles and early respiratory signs take weeks to become visible.
Do I need to quarantine an animal from a good breeder?
Yes. A reputable breeder reduces the risk considerably but does not remove it, and the cost of being wrong is your whole collection rather than one animal.
What substrate should I use during quarantine?
Paper towel or newspaper. The entire point is visibility: you are inspecting stools and watching for mites, and loose substrate hides both.
How do mites spread between enclosures?
Mostly on you. Hands, sleeves, cleaning cloths and shared tools move them between enclosures far more efficiently than the mites travel alone. Service quarantine last and wash thoroughly afterwards.
