Leopard Gecko Birthday Treats: What to Feed, What to Skip, and the Waxworm Situation

Leopard geckos are insectivores, they eat insects and only insects. A birthday feast is a prey variety event: a better-than-usual insect offering, possibly with a premium treat prey item that they don’t get on a regular basis.

The Birthday Prey Options

Per VCA Hospitals leopard gecko feeding guidance:

The everyday feeders (safe, nutritious):

• Mealworms, the most common leopard gecko staple. Important caveat: mealworms should be offered in a dish, not loose in the substrate. Loose mealworms can burrow into loose substrate and cause impaction if ingested with substrate material. Mealworm dish birthday feeding is appropriate.
• Crickets (gut-loaded)
• Dubia roaches, nutritionally superior to mealworms; many leos take them readily

The birthday premium treat prey:

• Waxworms: The waxworm is the ice cream of the leopard gecko world. Most leos pursue waxworms with visible enthusiasm. They’re very high in fat, too much fat as a regular diet causes obesity and fatty liver disease, but as an occasional birthday treat, 2–3 waxworms for an adult leo is appropriate and genuinely well-received.

• Hornworms: High moisture, soft body, calcium-rich. A birthday hornworm for an adult leo is an excellent premium treat. They’re larger than waxworms so size-appropriateness matters. Hornworm Feeder Insects
• Silkworms: Nutritionally excellent, high calcium, high moisture, low fat. A premium treat without the fat concerns of waxworms. Live Silkworm Feeder Insects

The Impaction Note

Leopard geckos kept on loose substrate (sand, crushed walnut shell) are at risk of impaction from accidentally ingesting substrate with prey. This risk is highest with mealworms, which are loose and can pick up substrate.

Birthday or not: feed in a ceramic or smooth-sided dish where prey can’t easily get into the substrate, or temporarily move the gecko to a paper towel-lined feeding container for the birthday feast if the main enclosure has loose substrate.

What to Avoid

• Fireflies and lightning bugs: Potentially toxic to reptiles
• Wild-caught insects: Parasite and pesticide risk
• Plant matter: Leopard geckos are insectivores; vegetables, fruit, and greens are not appropriate
• Superworms for juveniles: Too large; appropriate for adults only in appropriate sizes
