Carpet Beetle

On the Kapiti Coast there exists a couple of introduced species of carpet beetles. The most vulnerable homes are those that have light coloured woollen carpets or fur-shedding pets that live inside. Why these two? Wool and pet fur are the food source for carpet beetles. Preventing your chances of invasion by carpet beetles involves a strict vacuuming regime targeting pet fur, and other dust and debris. 

During summer, the adults resemble small ladybird sized beetles that, more often than not, they can be seen on outdoor flowers. These beetles are harmless. The problem occurs when they inadvertently are introduced into the interior of the home either on cut flowers or through open windows and doors. 

Carpet  beetle  larva

Carpet beetles lay their eggs in cracks or crevices of furniture or on floors near a woollen food source. Over summer months, the eggs hatch out into larvae (commonly referred to as ‘fuzzy’ or ‘woolly bears’). The damaging stage occurs over winter when the larvae feed on your carpet and begin to grow. 

Can carpet beetles be seen? Actually, larvae choose to remain out of sight as they feast on the base of the carpet fibres. You may see the shed and discarded exoskeletons of pre-moulted larvae and the upper fibres (of carpet) that come loose during vacuuming.


Extensive carpet damage from carpet beetle larvae

If you suspect carpet beetles in your home, begin by monitoring the extent of the carpet damage and the rate of spread. The damaged carpet will most likely resemble a condensation rot but its likely it is not. At risk areas include carpet around darkened floor areas, under dressers, behind curtains, along skirting boards, in closets, and beneath upholstered furniture.
