Iguana Reproduction Iguanas lay eggs even when they are not fertile. In fact, females will lay abo ut 20 to 70 eggs per year once they reach sexual maturity. When 65 days have passed after mating, the female iguana will deposit pale, cream-colored eggs into burrows that she constructs. Within 90 to 120 days, the eggs hatch and young iguanas will emerge. Where Do Iguanas Lay Eggs? Since they require a habitat that is extremely hot, iguanas lay their eggs in yards that get plenty of sunlight. In addition to unsightly eggs being deposited throughout residential areas, property owners also deal with the burrows that female iguanas create to protect their young. Iguana burrows ruin the appearance of lawns, as well as make landscaping difficult. These holes can be deep, so they also pose a threat to children and pets who play in yards. Iguana eggs can attract other unwanted pests in the area such as raccoons and snakes. Removing Iguana Eggs As iguanas never come back to check on their eggs or young, it may seem like a good idea to pick them up and simply place them elsewhere. However, iguanas and their eggs may contain Salmonella bacteria, which can be hazardous to human health. If egg removal is a must, homeowners should wear protective gloves, though it is best to leave this job to the experts. The professionals at Critter Control have the necessary training and experience to remove all eggs and assist in iguana control.
