What are Carpet Beetles?

Carpet bugs are small in size, but they can cause a lot of destruction to your personal belongings if they get into your home, start breeding, and are not dealt with and removed quickly. The adult carpet beetles themselves do not cause a lot of destruction to belongings as they tend to feed mainly on flowers and plants. However, they lay eggs that produce larvae, which feed on natural fibres such as fabrics, leather, upholstery, and carpet. 

Adult carpet beetles are up to four millimetres in length, but the larvae are much larger at around 2.5cm long. Adults have an oval and varied carpet beetle shell that is black, white and either orange or yellow. The larvae are a black carpet beetle or light brown in colour, and covered in dark hairs with three lighter, golden-coloured hairs on the abdomen. 

How Carpet Beetles Infest the Home

Carpet beetles can get into your home in several ways, including through open doors and windows. They may also get into the property through an infested item that is moved inside such as a plant or piece of furniture. Often, an infestation can be started by an adult carpet beetle simply getting in through an open door or window before laying eggs on carpets and other fabric items around the home. 

Carpet Beetles – The Damage They Cause

Natural fibres are food for carpet beetle larvae. Unfortunately, this means that they are going to eat away at your carpets, upholstery, rugs, and even clothing items. This causes damage to the items that they feed on and if left for too long, can cause items to develop holes. Carpet beetles are unlikely to cause any damage to the structure of your property itself, but they can be very destructive when it comes to the items inside it. 

How to Spot an Infestation of Carpet Beetles

Having your home infested by carpet beetles is an issue that should be dealt with as soon as possible. Not only can they cause damage to your belongings, but the infestation could also pose a risk to your health. Thankfully, understanding how to spot the signs of carpet beetles will help you notice any potential issues and deal with them sooner. 

Spotting One Carpet Beetle

If you see just one carpet beetle in your home, then you might think that there is nothing to worry about. However, this is a sign that the infestation has already started. The larvae will not be visible to the naked eye until they have formed, but there may be eggs nearby if you see a long, white worm moving on the carpet. If you find more than one carpet beetle in your home, this is a sign that the population is growing, and significant damage could occur if you don’t take steps to remove the pests.  

Bald Carpet Areas

Carpet beetles feed on carpets, which can cause bald spots to appear on them due to carpet beetle bites. You may notice narrow spots on the carpet that may look like a series of tunnels or holes. Since adult carpet beetles are quite small, these spots can easily be missed until there are lots of them, so keep your eyes out. This is one of the worst signs of having carpet beetle infesting your property as it means that not only adult carpet beetles are present but also larvae that is being developed under the furniture or underground. 

Damage to Furniture and Fabric Items

Carpet beetles can cause a lot of damage to woollen items, fabric items and upholstery. They especially feed on woollen rugs and knitted items like socks, scarves, and sweaters. If you have a woollen rug and notice that there is a discoloured area on it that isn’t a stain or other issue, then it could be due to carpet beetle larvae feeding in the area. There may be several carpet beetles living underneath your carpet or rug. 

Faecal Pellets

As they move around in your home, adult carpet beetles will leave faecal matter behind. It is usually white in colour and looks similar to small grains of flour or corn. Due to the colour and the size, they can often be quite difficult to spot on a carpet. 


Carpet beetles will leave their dead skin behind when they are done feeding on the furniture, carpets, or other fabric items in your home. These exoskeletons are empty husks that look similar to cocoons. Carpet beetle larvae will shed their skins several times as they mature, and these husks are likely to appear regularly in any areas where the larvae are feeding. 

How to Remove Carpet Beetles from Your Home

Whether you have noticed some sure signs of an infestation in your home, or suspect that they may be in your property, the good news is that there are several things that you can do to remove carpet beetles. How to get rid of carpet beetles:

Clean with Vinegar

White vinegar is an ideal cleaning solution and using it in your home can help with getting rid of carpet beetles. Use it to clean items such as windowsills, shelves, surfaces, drawers, and hangers. Along with this, use it for cleaning in the kitchen to clean away any food residue and dirt that might attract carpet beetles. 

Steam Clean

Experts in pest control recommend steam cleaning hard surfaces around your home to remove any carpet beetles. Not only is the heat and moisture from a steam cleaner great at getting various areas in your home extremely clean, but it will also remove any remaining beetles and eggs. 

Regular Vacuum Cleaning

Carpet beetle larvae will feed on various types of debris that might get left behind in the carpet including human and pet hair, dead skin, and dead insects. Regular vacuum cleaning means that not only are your carpets kept in better condition but there will be less in them for the carpet beetles to feast on. Along with this, vacuuming often gives you a better chance of cleaning up any larvae and eggs in your carpet before they have a chance to hatch and cause destruction. 

Make Sure Infected Areas are Thoroughly Cleaned

If you have found carpet beetles, then the first thing to do is clean the infected area as thoroughly as possible. Make sure that any larvae and debris are removed, and wipe down or launder surfaces, furniture, soft furnishings, clothes, and other fabric items. You may wish to use pesticides on the carpet beetles but do this with care as they can be poisonous to pets and toxic to humans. 

Inspect Plants Regularly

If you have houseplants in your home, then they might be attractive to adult carpet beetles who will feed on them. When you are watering and caring for your houseplants, it’s a good idea to look over them for any signs of the pests. You should always check for carpet beetles when you buy a new plant and bring it into your home.  

Wash on a High Temperature

If you have found carpet beetle or larvae on items that can be washed in a washing machine, then it’s a good idea to do this immediately. As long as it is safe to do so on the label, you can wash items such as throws, clothing, bedding, and other soft furnishings on a high or boil temperature using the washing machine to kill any carpet beetle larvae.  

Seal Dry Food Containers

Adult carpet beetle won’t usually feed on your carpets. However, they do like dried food, and may be attracted to this before laying eggs in your carpet and other soft furnishings. To prevent this from attracting carpet beetles to your home, make sure that all dried food is stored in a sealed and airtight container. 

Secure Windows and Doors

While there may not be much you can do about preventing carpet beetles from getting in when your window or door is open, you can make sure that it is harder for them to enter your home when they are closed by sealing any gaps or cracks around the doors and windows. Not only is this good for preventing carpet beetles but also draughts in the home.
