You are vacuuming the spare room and notice a patch of carpet that looks a bit threadbare. Maybe you blame the cat scratching at the door. Then you see a tiny, hairy grub wriggling near the skirting board.
That is not the cat. You are looking at the early signs of carpet beetles.
I see this every autumn across Auckland. The weather cools down, you shut the windows, and you turn on the heat pump. Suddenly, you have created a five-star resort for one of New Zealand’s most destructive fabric pests.
As a certified pest tech, I do not do panic. But I will give it to you straight: if you ignore these signs, you are looking at thousands of dollars in ruined wool carpets and clothing. Let’s break down exactly what you are dealing with and how we fix it.

The earliest signs of carpet beetles include bare, threadbare patches on wool carpets, tiny shed larval skins near skirting boards, and small, hairy grubs known as woolly bears. You may also spot adult beetles—small, mottled insects 2-4mm long—crawling near windowsills seeking light.
