Why Do Carpet Moths Often Appear Under Furniture in Cambourne Homes?

Carpet moths appear under furniture because larvae want somewhere dark, still and rarely cleaned. In a modern house, that means the fitted carpet under beds, sofas and wardrobes, even though the house itself may be only a few years old.

Newer Does Not Mean Immune

A common assumption in a newer estate such as Cambourne is that carpet moths belong in old houses. They do not. The insects are not drawn to age; they are drawn to keratin, the protein in wool, silk, fur and feathers. A wool-mix carpet fitted last year is as edible as one laid in 1980.

A carpet sold as synthetic can also surprise people. The pile may be mostly man-made, but the underlay can be wool or felt, and a wool blend is common. If there is damage, something in the floor build-up is keratin.

Why Under the Furniture Specifically

• Fitted carpet continues under beds and sofas, so there is plenty of food that is never walked on
• Vacuum heads rarely reach into the corners behind low furniture
• Spare rooms, studies and box rooms get little use, which suits the larvae
• Dust, hair and lint collect at the edges and add to the food supply

How the Damage Looks

Expect thinning or bare patches that begin at the skirting or under a piece of furniture, sometimes hidden by the gripper rod at the room's edge. You might find silken webbing and fine debris, which suggests moth, or small clean holes without webbing, which suggests carpet beetle. Beetles often arrive through open windows, so a Cambourne home with no history of a problem can still get them.

Sorting It Out

Start by pulling furniture clear and vacuuming the edges and under every piece, then empty the cleaner into an outside bin. Wash wool throws and blankets that can be washed. These steps help and cost nothing.

They will not remove a population that is already established in the pile and underlay. A retail spray does not reach where the larvae are feeding, and it may stain the carpet. That is where treatment is needed.

Cost and Next Step

Our Cambourne carpet moth and beetle service is £220 for the first room and £60 per extra room, fixed and confirmed before work starts. The cost guide sets out what that includes. If there is a re-appearance within 14 days of treatment, we re-treat at no charge.

Why Cambourne Houses Are Not Exempt

Cambourne grew quickly, and many homes were fitted out in the same way at around the same time, with wool-mix carpet on the stairs and landing, and thick underlay throughout. Where a family moves in with second-hand rugs or boxes of woollens from a previous home, those can bring larvae with them. It is also worth checking the stairs, since the carpet tucked behind each riser is as quiet as any floor under a bed.
