The pests can also proliferate on bird nests animal carcasses and dead insects cluster flies lady beetles stink bugs wasps etc which tend to be associated with attics chimneys basements and light fixtures.
The duration of the larval stage also depends on the type of carpet beetle species and temperature.
Most species of carpet beetle measure 1 to 4 mm in length as adults.
All species of carpet beetles undergo complete metamorphosis passing through the egg larval and pupal stages before developing into adults most carpet beetles develop up to four generations yearly while varied and black carpet beetles develop only one.
