Iguanas are mammals and don't lay eggs!
Green Iguanas (female) will dig holes in the ground to lay eggs. She will dig additional holes to confuse would-be egg poachers. After that she leaves the eggs, the hatchlings will grow up by themselves.
Not necessarily ! Many female lizards (including anoles, geckos and iguanas) will lay eggs at regular intervals. However - unless the female has been mated with a male, the eggs will be infertile, and will never hatch.
Marine iguanas are prey for Galapagos Hawks. When the females go into the caldera to lay eggs in the soft ash, the hawks have a killing spree! They kill by digging their talons into the iguanas' bodies.

Cockroaches have many natural predators. These include toads, frogs, iguanas, beetles, and geckos. Some types of wasps also lay their eggs on cockroach eggs, which then feed on the cockroach eggs.
They lay eggs and heat it with covered grass
Females lay their eggs about 65 days after mating (eggs take 59 to 84 days to develop before they are laid). Over the course of three days, females may up to 65 eggs, each measuring around 15.4 mm in diameter, and 35 to 40 mm in length (Frye, 1995). Eggs are deposited into nests which are located 45 cm to more than a meter deep, and may be shared with other females if nesting areas are limited.
