Crested Gecko Care in Ireland: Vivarium, Heating, Humidity & Diet

August 21, 2026

Crested geckos are arboreal reptiles from New Caledonia. They are capable climbers and jumpers that need a tall, planted environment, controlled heating, a daily humidity cycle, appropriate UVB and a nutritionally complete feeding plan.

Quick care overview

Commitment: commonly 15–20 years with good care.
Housing: one adult needs a tall vivarium at least 45cm wide, 45cm deep and 60cm high.
Temperature: overheating is a major risk; every heat source needs the correct thermostat.
Social needs: crested geckos are normally best housed individually.

Creating the right home

Use a secure, well-ventilated glass vivarium with dense foliage, cork, vines and branches at different heights and angles. Provide multiple daytime hides and horizontal resting routes near the upper half. Run the completed setup for at least a week before introducing the gecko.

Position the enclosure away from windows, radiators and draughts. Ireland’s cool rooms may require heat, but direct summer sun can overheat glass rapidly.

Create a basking area around 26–28°C and a cooler zone around 20–24°C.
Allow a safe night drop around 18–20°C where appropriate.
Control every heat source with a compatible thermostat and verify with digital thermometers.
Never use red, blue or black night bulbs.

Food and water

Use a reputable nutritionally complete crested gecko diet mixed and offered exactly as directed. Appropriate live insects can provide variety and hunting enrichment; gut-load them and use calcium or vitamin supplements according to the diet, UVB provision and veterinary guidance. Do not rely on mashed fruit alone.

Provide a shallow dish of fresh water even if the gecko also drinks droplets. Remove mixed food before it spoils and monitor intake and body weight.

Choose feeder insects no wider than the gecko’s head.
Remove uneaten insects so they cannot bite a resting gecko.
Do not guess supplement doses—follow product directions.
Use an elevated feeding ledge to support natural arboreal feeding.

Exercise, behaviour and enrichment

Provide safe climbing routes, broad leaves, cork tubes and enough cover for the gecko to move between warm, cool, bright and shaded areas while remaining concealed.

RSPCA guidance describes a normal humidity around 40–50% with short boosts up to about 80% after spraying. The enclosure should then dry back rather than staying waterlogged. Use a digital hygrometer and maintain good ventilation.

Zoofy practical tip

Arrange at least one route across the vivarium that allows the gecko to travel from the cool lower area to the warm upper area without crossing open space.

Health checks and when to call a vet

Provide low-level UVB with shade, targeting the output and distance recommended for the specific lamp; RSPCA guidance references a basking UVI around 0.7. Replace lamps according to manufacturer instructions because useful UVB declines before visible light fails.

Track weight, appetite, droppings, movement and shedding. Stuck shed around toes, marked weight loss, swelling, weakness, tremors, repeated falls or breathing changes requires a reptile vet. Never grab the tail; a dropped crested-gecko tail does not regrow.
