Carpet moths – just the name alone is enough to make you shudder. These tiny invaders might be small, but they can cause significant damage to your carpets, rugs, and even upholstered furniture. But don’t worry, with a bit of knowledge and the right approach, you can tackle a carpet moth infestation head-on and protect your home. In this post we’re exploring everything you need to know about carpet moths, from identifying these pesky critters to preventing and eliminating them.
What Are Carpet Moths?
Before we jump into solutions, it’s important to understand exactly what we’re dealing with. Carpet moths, also known as Trichophaga tapetzella, are small, winged insects that love to feast on natural fibers like wool, silk, and cotton. Unlike pantry moths, which are more interested in your food, carpet moths have a taste for the textiles in your home.
How Do Carpet Moths Get In Your Home?
Carpet moths can enter your home in several ways. They may come in through open windows or doors, especially if you live in an area with a high moth population. They can also hitch a ride on second-hand furniture, rugs, or clothing. Even new items can sometimes harbour moth eggs or larvae if they’ve been stored in infested warehouses. Additionally, moths may migrate from neighboring homes, especially in apartment buildings.
Identifying Carpet Moths and Their Damage
Spotting a carpet moth infestation early is key to minimizing damage. Some of the key signs of carpet moths in wool carpet or rugs include:
- The Moths Themselves: Adult carpet moths are tiny, usually about 5-7 mm long, with narrow, fringed wings. They’re often a dull, beige or grayish color, which makes them blend in with many home environments. Unlike clothes moths, carpet moths are less likely to be seen fluttering around lights.
- Larvae: The real culprits are the carpet moth larvae, which hatch from the moths’ eggs and start munching away at your carpets and fabrics. They look like tiny, creamy-white caterpillars and can be found hiding in the fibers.
- Damage Signs: The first thing you might notice is irregular holes or threadbare patches in your carpets or rugs. Pay close attention to areas that don’t get much foot traffic or light, like under furniture, as these are prime spots for moths.
- Cocoons and Webbing: Look for small, silky tubes or webbing on the underside of oriental rugs or carpets and around the edges. This is where the larvae spin their cocoons before becoming adult moths.
The Lifecycle Of Moths In Carpets
It’s important to get rid of moths in carpet as soon as you can. The carpet moth’s life cycle consists of four stages: egg, larva, pupa, and adult. The female moth lays eggs on natural fiber materials, and these eggs hatch into larvae within 4 to 10 days. The larvae stage is the longest, lasting anywhere from 2 to 12 months, depending on environmental conditions like temperature and humidity. During this time, the larvae feed on carpets and fabrics.
After feeding, the larvae spin cocoons and enter the pupal stage, which lasts 10 to 50 days. Finally, they emerge as adult moths, ready to reproduce and continue the cycle. Adult moths live for about 2 to 4 weeks but do not cause damage themselves.
What to Do If You Find Carpet Moths

If you’ve spotted signs of carpet moths, don’t panic. Here’s a step-by-step plan to tackle the infestation:
- Deep Clean Your Home:
- Vacuum Thoroughly: Go over every inch of your carpets, rugs, and upholstered furniture. Pay special attention to the edges and underneath heavy furniture.
- Dispose of the Vacuum Bag: Moth eggs and larvae can survive inside your vacuum, so empty the bag or canister outside immediately after cleaning.
- Wash or Freeze Affected Items:
- Wash Fabrics: Any removable fabrics like cushion covers, throws, and rugs should be washed on the highest temperature that’s safe for the material.
- Freeze Delicate Items: For items that can’t be washed, like delicate rugs or woolens, seal them in a plastic bag and place them in the freezer for at least 72 hours. This will kill any eggs or larvae.
- Apply Insecticides or Natural Remedies:
- Insecticidal Sprays: Use a carpet moth spray specifically designed for textiles. Follow the instructions carefully and ensure the room is well-ventilated.
- Diatomaceous Earth: This natural powder can be sprinkled onto carpets and rugs. It works by dehydrating and killing the larvae.
- Vinegar Solution: A mixture of equal parts water and white vinegar can be sprayed onto affected areas to clean and deter moths.
- Use Moth Traps:
- Pheromone Traps: These sticky traps attract and catch male moths, disrupting their breeding cycle. Place them in areas where you’ve noticed moth activity.
- Call in the Professionals:
- If the infestation is severe or you’re not having success with DIY methods, it might be time to call a pest control professional. They have access to stronger treatments and can ensure the problem is fully resolved.
Is It Possible To Get Rid Of Carpet Moths Naturally?

If you prefer to tackle carpet moths without resorting to chemical treatments, there are plenty of natural methods that you can try. However, although they may help to reduce the number of moths, you may need to consider other methods to help rid your home of a full-blown infestation.
Here are some natural methods you could try to get rid of carpet moths naturally.
- Essential Oils:
- Lavender Oil: Mix a few drops of lavender essential oil with water in a spray bottle and spritz it onto carpets, rugs, and upholstery. The scent is pleasant for humans but repels moths.
- Eucalyptus and Peppermint Oils: These oils also work well as natural moth repellents. Combine them with water and spray around infested areas.
- Herbal Sachets:
- Create sachets filled with dried lavender, rosemary, or bay leaves and place them in drawers, closets, and under furniture to deter moths.
- Baking Soda Treatment:
- Sprinkle baking soda generously over carpets and rugs, let it sit for a few hours, and then vacuum thoroughly. This helps to absorb moisture and deter moth larvae.
- Cedarwood Products:
- Cedarwood blocks, chips, or oils are natural moth deterrents. Place them in problem areas or use cedarwood oil mixed with water as a spray.
- Sunlight and Fresh Air:
- Moths dislike bright light and fresh air. Take your rugs and textiles outside on a sunny day and shake them out thoroughly. Sunlight helps kill moth eggs and larvae.
- Steam Cleaning:
- Steam cleaning your carpets and upholstery can effectively kill moth eggs and larvae without using chemicals. The high temperature of the steam penetrates deep into the fibers.
By incorporating these natural methods, you can keep your home moth-free while avoiding harsh chemicals.
Long-Term Maintenance After A Carpet Moth Infestation
Even after you’ve dealt with an infestation, it’s important to stay vigilant to prevent it from happening again. Here are some long-term strategies to employ in your home to avoid future problems with the pesky carpet moth.
- Regular Inspections: Periodically check your carpets, rugs, and furniture for signs of moths, especially in areas that are less frequently used.
- Maintain Cleanliness: Continue regular vacuuming and dusting to ensure no new moths can find a home.
- Refresh Natural Deterrents: Replace lavender sachets and cedar blocks every few months to keep their scent strong and effective.
- Keep an Eye on Humidity: Use a hygrometer to monitor humidity levels in your home and adjust with dehumidifiers as needed.
Preventing Carpet Moth Infestations

If you’ve been lucky enough to avoid issues with carpet moths, you’ll know only too well that prevention is always better than cure. Here are some practical steps you can take to keep carpet moths out of your home sweet home.
- Regular Vacuuming: Moths love to settle in undisturbed darker areas, so vacuum regularly, especially under furniture, under rugs, along skirting boards, and in corners. Don’t forget to vacuum upholstered furniture and curtains as well.
- Control Humidity: Carpet moths thrive in warm, humid environments, so it’s a good idea to yuse dehumidifiers or air conditioning to keep your home’s humidity levels in check.
- Rotate Furniture: Moving your furniture around occasionally prevents moths from finding a quiet, dark place to settle.
- Store Fabrics Properly: If you’re storing rugs, blankets, or other textiles, make sure they’re clean and stored in airtight containers.

By staying proactive with prevention, acting quickly at the first sign of trouble, and maintaining a clean environment, you can keep your carpets, rugs, and furniture looking their best. Remember, a little vigilance goes a long way in keeping your home moth-free!
FAQs About Carpet Moths
Do moths eat carpet?
Yes, certain types of moths, particularly carpet moths (Trichophaga tapetzella), feed on natural fibers found in carpets, rugs, and upholstery. The larvae are the ones that cause damage as they consume materials like wool, silk, and cotton.
What is the difference between carpet moths and clothes moths?
While both carpet moths and clothes moths belong to the same family and have similar habits, they differ slightly in their preferred habitats and appearance. Carpet moths primarily target carpets, rugs, and upholstered furniture, while clothes moths focus on clothing, especially wool and silk garments. Carpet moths are generally smaller and less attracted to light compared to clothes moths.
Does salt kill carpet moths?
Salt can help in deterring carpet moths but is not a guaranteed method to kill them. When sprinkled onto carpets and rugs, salt can dehydrate and kill some larvae by drawing out moisture. However, it may not be effective against eggs or adult moths. The best way to deal with a carpet moth problem is to combine salt treatment with vacuuming and other natural or chemical methods to ensure a thorough elimination of the infestation.
