Do Leopard Geckos Bite? Does It Hurt?
Why it usually doesn't hurt much
Leopard geckos have many small, blunt teeth adapted for gripping insects, not tearing flesh — most adult bites feel like a firm pinch, and many don't break skin at all. A hatchling's bite is essentially unnoticeable.
Common triggers
Feeding-response bites happen when a gecko mistakes a finger for food, especially around feeding time or if hands smell like feeder insects. Defensive bites happen when a gecko feels grabbed, cornered, or startled — often linked to being handled from directly above or picked up too fast.
Reducing the chance of it
Wash hands before handling to remove feeder scent, avoid handling right around feeding time, approach from the side rather than from above, and let the gecko walk onto your hand rather than grabbing it.
If it does happen
Stay calm and let go of any grip reflex rather than yanking away, which can startle the gecko further. Clean any broken skin as a normal minor precaution.

A single adult leopard gecko needs a 20-gallon long tank as an absolute minimum, with a 36x18 in (40-gallon breeder) footprint now considered the recommended standard — plus a secure lid, an under-tank heater on a thermostat, a thermal gradient, at least three hides, and a shallow water dish.
Set up in this order: substrate, then heat source wired through a thermostat, then hides and water dish, then decor — and run the whole enclosure for at least 24–48 hours to confirm stable temperatures before your gecko moves in.
Hatchlings can start in a 10-gallon tank or tub, juveniles do well in 20 gallons, and adults need a 20-gallon long as an absolute minimum — with 36x18 in (40-gallon breeder) now the widely recommended standard, not just an upgrade.
Heat a leopard gecko enclosure with an under-tank heater and/or overhead heat source (halogen or deep heat projector) wired through a thermostat — a thermostat is mandatory, not optional, and heat rocks should never be used.
Leopard geckos can survive without UVB using dietary D3 supplementation, but current husbandry guidance now recommends low-level UVB (roughly 2–6% T5) as best practice — it improves D3 synthesis, bone density, and natural behavior, and views on it have shifted significantly from older nocturnal-species advice.
Keep ambient humidity around 30–40% across most of the enclosure, with a dedicated humid hide raised to roughly 70–80% to support smooth, complete sheds.
