How to Breed Lizards

Provide a suitable environment for the lizards. Lizards need very specific conditions to live in. Keep the lizards in at least a 30-gallon terrarium. Research the lizards' country of origin and set the humidifier and heat lamps to the temperature and humidity of their natural habitat. Rain-forest lizards such as the iguana, for example, who live in Central and South America, will not thrive in desert like conditions.

Provide consistent day and night cycles. Many lizards' circadian rhythms take around one year to become accustomed to new day and night cycles. Emulate their natural habitats' day/night cycle as closely as possible. Be patient, they may not breed until they have adapted to the new rhythm.

Keep no more than one male per 30-gallon terrarium. In general, male lizards are territorial and aggressive towards other males. You may, however, keep more than one female per male lizard. Acquire a sufficiently large enough cage to house the lizards, especially if you decide to keep more than one male in the terrarium at a time. They must have space enough to avoid each other. Prevent certain breeds of male lizards, such as geckos, from even seeing another male even if they are in different enclosures.

Set aside a place where they can lay eggs. Cut a hole into a plastic tub such as an old margarine tub or large coffee canister. Lay damp moss or soil in the bottom of the tub where they can lay their eggs. Keep the tub heated to between 80 and 84 degrees. Keep the soil or moss slightly damp at all times, except in the case of day geckos, who's eggs decay in damp conditions. Lizard eggs generally hatch withing 55 days. Keep a ready supply of insects at hand to feed the female and baby lizards during and after the 55 days.
