No. Gargoyle geckos do not tolerate hot summers, and heat is the most common way a healthy one dies. They are cool-climate New Caledonian forest animals, and a room that drifts into the high 80s is a genuine emergency rather than a discomfort.
Quick answer
- Correct range is roughly 72–78°F. Normal room temperature in most homes.
- Sustained temperatures above the mid-80s are dangerous, and the low 90s can kill within hours.
- No basking lamp. No heat mat. Cooling is the equipment that matters for this species.
- Night-time drops are welcome, not a problem.
- The warning signs are quiet: lethargy, refusing food, sitting on the cool floor instead of climbing.
Why they are so heat-sensitive
Rhacodactylus auriculatus comes from forest and scrub in southern New Caledonia, where it is nocturnal and spends the day in cover. It never evolved to sit under a hot sun, and unlike a desert lizard it has no behavioural repertoire for shedding heat. In an enclosure it cannot leave, a hot room is inescapable.
This is the same constraint that governs crested geckos, which come from the same islands and fail the same way. If you keep both, one hot week endangers the whole collection at once.
What to do about a hot house
| Approach | Notes |
|---|---|
| Room choice | The cheapest fix. Basements and north-facing interior rooms run several degrees cooler than the rest of a house |
| Air conditioning | The reliable one. If you keep New Caledonian geckos in a hot climate, this is husbandry equipment, not a luxury |
| Placement | Away from windows, direct sun and any electronics that dump heat |
| Airflow | A fan moving room air helps; do not blow it directly into the enclosure and dry the animal out |
| Evaporative cooling | Light misting at the hottest part of the day helps briefly. It is a stopgap, not a plan |
| What not to do | Ice packs inside the enclosure. The swing does more harm than the heat |
Measure with a thermometer inside the enclosure at the height the animal actually uses, not on the room wall. The top of a tall vertical enclosure runs warmer than the floor, and that is where a gargoyle sleeps.
Signs it has gone too far
Heat stress in this species is undramatic until it is severe. Watch for an animal that stops climbing and stays on the substrate, refuses food for several days in hot weather, sits with its mouth open, or looks slack and unresponsive. Move it to a cooler room and let it stabilise gradually rather than plunging it — and if it does not recover promptly, that is a reptile vet call.
The mirror-image mistake, for contrast, is on the desert side: uromastyx need a 120–130°F basking surface and die of damp instead. Species, not general reptile rules, decide everything here.

Common questions
What temperature is too hot for a gargoyle gecko?
Sustained temperatures above the mid-80s°F are dangerous, and the low 90s can be fatal within hours. Aim for 72–78°F.
Do gargoyle geckos need a heat lamp?
No. They are nocturnal forest geckos and normal room temperature suits them. A basking lamp is a hazard rather than a help.
How do I keep a gargoyle gecko cool in summer?
Move the enclosure to the coolest room you have, keep it away from windows and sun, use air conditioning if your climate demands it, and measure at the height the gecko actually rests.
What are the signs of overheating in a gargoyle gecko?
Staying on the floor instead of climbing, refusing food during hot weather, open-mouth breathing, and general slackness. Cool the animal gradually and contact a reptile vet if it does not recover.
Can gargoyle geckos and crested geckos take the same temperatures?
Yes. Both are New Caledonian species with the same cool requirement and the same vulnerability to heat, so one hot room threatens both.
