Frequency: Juveniles shed more frequently — sometimes every 2–3 weeks. Adults slow to every 4–8 weeks. A gecko that hasn't shed in 10+ weeks may be experiencing a husbandry problem. Check humidity first — it's the most common factor for this species.
Shed phases
PHASE 1Pre-shed (a few days before)
What you'll see
- —Skin appears dull, grey, or milky
- —Eyes may cloud over
- —Reduced appetite — completely normal, do not force-feed
- —More time tucked into foliage or a hide
- —Less active than usual
What to do
Confirm humidity is holding at 60–80% with a hygrometer, and mist as usual. Do not handle unless necessary. A properly humid enclosure is usually all this species needs to shed cleanly.
PHASE 2Active shed (typically completes in one session)
What you'll see
- —Gecko rubbing against branches or cork bark
- —Visibly pulling at loose skin
- —Skin usually comes off as one whole piece, unlike patch-shedding species
- —May eat the shed skin immediately after — normal behaviour
What to do
Do not interfere. Do not peel skin off manually unless a retained piece is causing harm. Most geckos complete a full shed in under 24 hours.
PHASE 3Post-shed check
What you'll see
- —Bright, clean colouration
- —Clear eyes
- —All toes accounted for with no retained shed rings
What to do
Check every toe, both eye caps, and the tail tip within 24 hours of shed completion. These are the three common sites for retained shed. Normal appetite should return within 24–48 hours.
Whole-enclosure humidity, not a single hide
Why no dedicated hide
Unlike species that need a small humid microclimate inside an otherwise dry tank, a mourning gecko's whole enclosure should already run at 60–80% humidity. A single humid hide isn't the mechanism here — consistent misting across the entire enclosure is.
Misting routine
Mist once or twice daily so humidity spikes noticeably after each session and drops somewhat before the next — this natural cycle is healthier than trying to hold humidity artificially high and constant.
Ventilation still matters
Good airflow (mesh sides, a well-ventilated top) keeps that humidity from turning into stagnant, mould-prone dampness. Humidity and ventilation work together, not against each other.
Confirm with a hygrometer
A digital hygrometer is the only reliable way to know your misting schedule is actually holding the enclosure in range — don't rely on guesswork or how the substrate looks.
Retained / stuck shed
Why it matters
Shed rings on toes cut off circulation. Even one missed shed ring can restrict blood flow — two or three shed layers cause permanent toe loss. Check every shed, every time.
How to fix it
Soak the gecko in a shallow warm bath (no deeper than ankle height) for 10–15 minutes. Gently roll a damp cotton bud across the affected toe. The skin should slide off. Never pull or force it.
Why it matters
Retained eye caps are immediately visible as a dull, grey film over the eye. Left untreated they cause eye infections, corneal damage, and blindness. Retained caps also happen in layers — you may not notice until several have accumulated.
How to fix it
Do not attempt to remove eye caps with tweezers or cotton buds on the eye surface. See a reptile vet. A warm damp cotton pad held gently over the eye for 2–3 minutes may loosen the cap — but eye caps are vet territory.
Why it matters
Retained shed on the tail tip constricts the tip and can cause it to die and fall off. Less urgent than toes or eyes, but still requires attention.
How to fix it
Warm soak for 15 minutes, then very gently roll the retained skin off using a damp cotton pad. The skin should slide rather than peel.
Why it matters
Shed skin around the nostrils can block airflow. Around the lips it can restrict the mouth. Uncommon but worth checking on every shed.
How to fix it
Warm soak and gentle removal with damp cotton bud. If the gecko is distressed, stop and try again later.
Root causes of problem sheds: Retained shed in this species almost always traces back to insufficient humidity — check your hygrometer reading and misting frequency first, not temperature (which usually isn't the issue for a species that doesn't need supplemental heat). Cork bark and rough branches to rub against help too. Never repeatedly force a gecko to soak without fixing the underlying humidity — you'll be treating the symptom forever.
What not to do: Do not pull or peel shed skin off a gecko. Do not soak a gecko in deep water. Do not leave a gecko alone for days around shed time without checking. Do not panic if they skip a meal — it's normal and will resolve within 48 hours of a successful shed.
