Carpet Beetle Larva

 

Larvae of the Carpet Beetle

Carpet beetles undergo complete metamorphosis. In length, the life cycle of these beetles ranges from two months to many years. The life cycle of these beetles starts when the adult female beetles lays their eggs. They can lay their eggs indoors and also infest the mice, nest of birds and other insects also. At a time, female beetle can lay 100 eggs. Within 7 to 35 days, the eggs will hatch into the larva. The larval stage is the destructive stage of these beetles. Adult carpet beetles are fliers, so they can move from one place to another. Larva can survive without food for many weeks. Larva can take over a year to develop into adults. The duration of the pupal stage varies. And in the spring or summer season, Adult beetles emerge. Within 9 months to 2 years, young beetles develop into the adults. Climate and food also affect the development of the beetle.
