Carpet beetles live from as short as 9 months to as long as 3 years.
The lifespan of the carpet beetle depends on their environment and their diet.
The carpet beetles larvae pupate in the last larval skin, with the pupal state lasting from 6 to 24 days.
Carpet beetles can feed on things such as your bedding etc
Carpet beetles are also often mistaken for bed bugs but carpet beetles are different than bed bugs and unlike bed bugs the carpet beetles do not bite humans.
Although if a carpet beetle crawls across your skin the carpet beetle can cause a red, itchy rash due to their prickly larval hairs.
