Need help with Carpet Beetles?
Carpet beetle treatment service
Our carpet beetle treatment starts with an assessment of the affected rooms and the areas where larvae are most likely to be present. This often includes carpets, rugs, skirting edges, wardrobes, under furniture, under beds and other quiet areas where natural fibres, dust, hair or debris can build up.
We normally apply a professional residual treatment to affected hard and soft surfaces, followed by ULV space treatment where appropriate. This helps distribute treatment into cracks, edges and difficult areas where carpet beetles or larvae may be hidden.
Carpet beetle treatment usually requires two visits around two weeks apart. The follow-up visit allows us to reassess the affected areas and apply further treatment where needed.
Preparation and aftercare are important. We will explain what needs to be cleaned, moved, vacuumed or left undisturbed before and after each visit so the treatment has the best chance of working properly.
Before the first visit, the affected rooms should be cleaned and vacuumed thoroughly where possible. Pay particular attention to carpets, rugs, skirting edges, under beds, under furniture, wardrobes, cupboards and other quiet areas where larvae may be present.
After treatment, avoid deep cleaning treated surfaces until we advise it is appropriate. Vacuuming too soon can reduce the residual effect of the treatment, especially around carpet edges, skirting boards and other treated areas.
We normally return around two weeks later for the follow-up visit. Before the second visit, repeat the preparation steps so we can reassess the affected areas and apply further treatment where needed.
How to prevent a carpet beetle infestation
Keep a regular cleaning routine
Regular cleaning can help reduce the risk of carpet beetle activity by removing dust, hair, lint, dead insects and other organic debris that larvae may feed on.
Pay particular attention to quiet, undisturbed areas such as under beds, under furniture, carpet edges, skirting boards, wardrobes, airing cupboards, storage areas and around rugs or curtains.
Where possible, move furniture periodically and vacuum beneath it. Professional cleaning of carpets, rugs and curtains may also help remove debris and residues that can attract fabric pests.
Check high-risk items and entry points
Second-hand furniture, vintage clothing, rugs, animal-fibre textiles, dried flowers, taxidermy, stored fabrics and old bird nests can all increase the risk of carpet beetles being introduced or supported in a property.
Inspect second-hand or stored items before bringing them into the home, especially if they contain wool, silk, feathers, fur, hair or other natural materials.
If there are old bird nests in or around the roofline, loft or vents, these may need to be removed safely where access allows. Insect monitors can also help detect early activity before damage becomes more noticeable.
If cleaning and prevention steps are not stopping the activity, see our guide on when to call a professional pest controller.
How much does carpet beetle treatment cost?
Our carpet beetle treatment starts from £260 + VAT for a studio flat and normally includes two visits arranged around two weeks apart.
A one-bedroom flat is typically £380 + VAT. Larger properties are usually charged from £49 + VAT per additional bedroom.
Final pricing depends on the number of rooms affected, preparation, access and the level of activity found during the visit.

Carpet beetles FAQs
Carpet beetles are small insects whose larvae can damage natural-fibre materials inside homes. The adult beetles are often found outdoors, where they feed on pollen and nectar, but they may enter buildings through windows, vents, gaps or on infested items.
The main damage is caused by the larvae, not the adult beetles. Larvae feed on materials such as wool, silk, feathers, fur, hair, dead insects, dust and other organic debris.
Inside a property, carpet beetle activity is often found in quiet, undisturbed areas such as carpet edges, under furniture, wardrobes, airing cupboards, loft spaces and around stored fabrics.
Adult carpet beetles are small, rounded insects, often around 2–4 mm long. They can look a little like tiny ladybirds, but their bodies are patterned with white, pale yellow, brown and black scales.
The larvae are usually more important from a damage point of view. Carpet beetle larvae are often called “woolly bears” because they are hairy, brownish and banded. They may curl up when disturbed.
If you are finding small beetles near windows, or hairy larvae around carpets, wardrobes, skirting edges or stored fabrics, this may indicate carpet beetle activity inside the property.
The carpet beetle life cycle can take several months and, in some cases, close to a year depending on temperature, food sources and conditions inside the property.
The main stages are egg, larva, pupa and adult. The larvae are the stage most associated with damage because they feed on natural fibres and organic debris such as wool, silk, feathers, fur, hair, dead insects and dust.
Eggs are often laid close to suitable food sources, including carpets, rugs, stored fabrics, wardrobes, old bird nests, dead insects or quiet areas where debris has built up. Larvae may then spread into nearby rooms or hidden areas as they develop.
This is why treatment needs to target more than just visible adult beetles. Cleaning, preparation, residual treatment and follow-up all help address the wider life cycle.
Adult carpet beetles mostly feed on pollen and nectar, but the larvae feed on natural materials and organic debris. This can include wool, silk, feathers, fur, hair, dead insects, dust, lint and animal fibres.
Inside a property, larvae may damage carpets, rugs, curtains, clothing, upholstery, stored fabrics and items kept in quiet, undisturbed areas.
The longer carpet beetle activity goes unnoticed, the more damage larvae can cause to natural-fibre items. Early cleaning, inspection and treatment can help reduce further damage.
No. Biscuit beetles are different from carpet beetles. Carpet beetle larvae usually damage natural fibres and organic debris, while biscuit beetles are normally linked to dried food storage.
Biscuit beetles can infest products such as flour, biscuits, cereals, spices, pet food, dried herbs and other dry goods. They may also chew through paper or thin packaging, so the source is not always obvious at first.
If biscuit beetles are found indoors, the first step is to inspect cupboards, drawers and stored food carefully. Any infested food should be sealed and disposed of, then the storage area should be cleaned thoroughly before replacement products are returned.
If you are finding small beetles near windows, cupboards or stored food areas and are unsure whether they are carpet beetles or biscuit beetles, we can help identify the pest and advise on the right next step.
The first step is to inspect the cupboards, drawers or storage areas where dry food is kept. Biscuit beetles are often linked to products such as flour, biscuits, cereals, spices, dried herbs, pet food and other stored dry goods.
Check packaging carefully for small holes, live beetles, dead beetles, larvae or loose food debris. Any infested or suspicious food should be sealed and disposed of outside the property.
Once the source has been removed, the affected cupboards should be emptied, vacuumed and cleaned thoroughly. In some cases, treatment may be applied to cracks, edges or hard surfaces where beetles may remain, but food products must not be treated directly.
Biscuit beetles sometimes come from nearby bird nests and they can then find their way into your home by crawling through tiny gaps or flying through the window.
However, they are more likely to be introduced with our shopping, especially from shops with very little shelf turn over.
The best thing to do is regularly turn over your dry food – don’t keep food in your cupboards for years and years. Routinely clear your shelves and check the expiration dates – throw away anything that is expired and it’s a hotspot for Biscuit beetles.
As you buy perishable food, check the integrity of the packaging. Alternatively, the best strategy is to keep your dry foodstuff in airtight containers.
