Why reptiles get stuck shed
Reptiles shed their outer skin as they grow. A healthy shed comes off in large pieces (snakes often in one piece). Stuck shed (dysecdysis) happens when the old skin dries out before it loosens. Common causes:
- Humidity too low for the species
- No humid hide (a hide with damp moss)
- Dehydration: no water dish, or water the animal can't easily reach
- Nothing rough to rub against: bare tanks with only smooth surfaces
- Less often: mites, illness, injury or poor nutrition
Check these areas
| Area | Why it matters |
|---|---|
| Toes and feet (geckos, lizards) | Rings of shed constrict and can cost toes |
| Tail tip | Same risk; tail tips can die off |
| Eyes (snakes: "eye caps") | Retained caps can build up and damage the eye |
| Around the vent and head | Can trap bacteria |
How to remove stuck shed safely
1. Warm soak or "sauna"
- Lizards and geckos: a shallow bath of lukewarm water, about 85–90°F (29–32°C), no deeper than the animal's shoulders, for 10–15 minutes. Supervise the whole time.
- Snakes and small geckos: a "sauna" is often easier. Put the animal in a ventilated tub with damp (not dripping) paper towel, close the lid, and leave it somewhere warm for 20–30 minutes.
2. Gently roll the shed off
Use a damp cotton swab or your damp fingertip and roll the loosened skin in the direction it would naturally come off. For snakes, letting them crawl through a damp towel in your hands often helps.
3. Stop if it won't come off easily
Never pull or pick at shed that isn't loose. You can tear the new skin underneath. Repeat the soak once or twice a day, and the shed will usually loosen over 1–2 days.
Retained eye caps (snakes)
Don't try to pick off eye caps with fingernails or tweezers. Raise humidity, use a humid hide, and the cap usually comes off with the next shed. A damp cotton swab gently rolled from front to back after a sauna can help. If it doesn't come off, or the eye looks cloudy, sunken or swollen, see a reptile vet.
When to see a vet
- Shed on toes or tail tips that won't come off after a couple of days, or skin that looks dark, swollen or dry
- Repeated bad sheds despite correct humidity
- Retained eye caps that don't come off
- Tiny moving dots on the skin or in the water bowl (possible mites)
How to prevent stuck shed
- Check humidity with a digital hygrometer, and match it to the species (see the care sheets).
- Always provide a humid hide: a hide packed with damp sphagnum moss.
- Keep a water dish the animal can easily reach and climb out of.
- Add rough surfaces: cork bark, branches, slate and rocks to rub against.
- Raise humidity a little when you see a shed coming (dull colours, cloudy eyes in snakes).

FAQ
How do I get stuck shed off my leopard gecko? A warm shallow soak or damp-paper-towel sauna, then roll the loose shed off with a damp cotton swab.
Is stuck shed dangerous? It can be, especially on toes, tail tips and eyes.
What causes stuck shed? Mostly low humidity, no humid hide or dehydration.
