Everything You Need to Know About Carpet Moths

If you search the phrase "small but mighty," chances are you'll see a photo of a carpet moth. These little critters are miniscule, but the damage they cause to carpets and rugs can seem astronomical. Carpet moths are attracted to animal-based fibers, which makes your new wool rug an easy target for a late-night feeding frenzy.

From home remedies and over-the-counter moth traps to professional extermination, there are many solutions to eradicating frustrating carpet moth infestations.

Carpet moths are tiny-winged moths that feed on keratin found in natural, animal-based fibers such as wool and silk. The two most common types of carpet moths are referred to as webbing clothes moths (or carpet clothes moths) and case maker moths. Both types are very similar in size and appearance and capable of laying multiple eggs at a time.

The larval stage is where they cause the most damage. During this phase, carpet moth larvae get busy feasting on as much keratin they can find, leaving holes in your carpet and other nasty surprises. Once they're nice and full, they retreat to their casings or cocoons and the winged moths appear about eight to 10 days later.

What Are the Signs You Have Carpet Moths?

While spotting the critters in action is probably the most common sign of moths in carpets, there are also several additional signs that can indicate an infestation. If you suspect a rug moth invasion, keep an eye out for these clues:

• Black specks on carpeting: Tiny black or brown spots on the carpeting may be droppings released by the moth larvae as they feed and build their casings. The specks look a lot like pepper, and they're often found in the carpet's crevices. 
• Eggs and visible larvae on carpets or clothing: Carpet moth eggs are tiny and difficult to see on most carpeting, but you may spot an egg or two hiding out on the carpet fibers if you use a magnifying glass. The eggs look like tiny white specks, and the larvae are cream-colored and similar in appearance to small worms. They're often found crawling on carpet surfaces and in woven crevices. You may also spot adult moths or larvae on furnishings or clothing. 
• Carpet damage: As carpet moth larvae feed on carpet fabric, it can cause tearing and torn fibers and bare areas where the yarn has been completely torn out. If your carpet has several bare patches or appears ripped or ragged, carpet moths may be to blame.

What Are Some Methods for Getting Rid of Carpet Moths?

If your carpets are severely damaged or you suspect a significant carpet moth infestation, it's important to contact a pest control specialist as soon as possible. They can thoroughly assess the situation by inspecting your carpet and analyzing other physical evidence like droppings and larvae activity.

For minor infestations, the following remedies may be helpful:

• Professional steam carpet cleaning: Steam and hot water extraction carpet cleaning procedures may be effective at eliminating carpet moth eggs and larvae. Additionally, professional carpet cleaning companies sometimes offer carpet moth cleaning treatments. 
• Rug shaking: If your rugs aren't attached to the floor, taking them outdoors and vigorously shaking them may help dislodge eggs and larvae. 
• Moth spray and moth powder: Over-the-counter moth sprays and powders can help kill carpet moths and larvae on contact. Be sure to vacuum after using these treatments to remove any lingering bug residue.

How Do You Prevent Carpet Moths From Coming Back?

After you've treated your carpet and eliminated the moth infestation, it's time to take some important steps to prevent their return. In the first week or so following your carpet moth treatment, it's a good idea to vacuum every day. This helps ensure any remaining moths, carpet moth larvae and egg casings are completely removed.

To keep your carpets moth-free for the foreseeable future, follow these helpful tips:

• Set up sticky moth traps: Sticky moth traps are treated with glue and pheromones that naturally attract moths. Placing these traps near your carpeting and in your closets may help halt new moths before they lay eggs and start feeding.
• Perform weekly carpet inspections: Following treatment, inspect your carpets and rugs on a weekly basis. If you spot any new activity, contact an exterminator right away. 
• Clean underlying flooring when replacing old carpet: If you decide to replace your old carpeting, be sure to thoroughly clean the underlying flooring. You can also sprinkle moth powder or treat the flooring with moth spray prior to laying the new carpet.
