Understanding the clothes moth life cycle
Clothes moths go through four stages: egg, larva, pupa, and adult.
A single moth can lay hundreds of eggs during its lifetime, typically in environments that offer ideal conditions for growth — such as your wardrobe, where darkness, stillness, and an abundant food source — namely, your favorite sweaters — come together.
While moth eggs are nearly impossible to spot with the naked eye, you may notice small white cocoons, often found in the corners of closets or attached to garments.
Once the eggs hatch, the larvae begin feeding. These moth larvae are responsible for the damage to your clothes.
Although most destruction occurs at this stage, it is essential to address all stages of the life cycle to prevent a moth infestation in your wardrobe, especially by eliminating adult moths before they lay new eggs.
Why do moths appear in spring?
Warmer temperatures accelerate the development cycle of clothes moths. While they can be present year-round, spring is when their activity peaks.
This season also coincides with wardrobe changes — when winter garments are stored away. Improper storage can easily lead to moths in clothing.
Travel can also introduce moths into your home, as garments may be exposed to infested environments.
For all these reasons, spring requires extra vigilance when it comes to moth prevention.
How to prevent moths in your wardrobe
Regular cleaning is the most effective way to prevent moths in your closet.
Your wardrobe should be clean, dry, and well-ventilated. Moths thrive in dark, warm, and undisturbed environments.
Vacuum thoroughly, especially in corners and storage areas. If moths are present, dispose of the vacuum contents immediately.
Before storing your garments, always wash them. Body oils, hair, and skin residues attract moths and signal ideal breeding conditions.
Store your clothes in clean, airtight containers to reduce the risk of infestation.
As we explain in our guide to caring for wool garments proper maintenance is your first line of defense against textile pests.
Natural moth repellents
Natural moth repellents are highly effective as a preventive measure.
Moths are repelled by strong scents, which act as a natural deterrent.
This is why cedarwood is commonly used to prevent moth infestations. You can also use lavender sachets or essential oils such as eucalyptus, thyme, or lavender. Vetiver roots and camphor are also known to be effective natural moth repellents.
To maintain their effectiveness, it is important to regularly “refresh” these scents. For example, if you are using cedarwood, it should be lightly sanded each season to release its aroma again, and you can even add a few drops of cedar essential oil. If you are using lavender or thyme, remember to replace the contents of the sachets regularly.
If you choose to use essential oils, whether in drops or spray form, it is important to follow usage precautions carefully. Avoid direct contact between oils, camphor, or vetiver and your textiles to prevent stains.
Moth sprays: should you use them?
There are many moth sprays available on the market, but most contain chemicals that can be harmful to health.
Some plant-based alternatives can help treat mild infestations while being safer to use.
Always follow instructions carefully: test on a small area, ventilate after use, and keep away from children and pets.
Moth sprays can be used both preventively and curatively, but in the case of severe infestations, professional treatment may be necessary.
Traveling without bringing moths home
I’d like to share a personal experience.
A few years ago, I had the chance to stay in a beautiful guesthouse, decorated with linen fabrics and vintage furniture. I’m the kind of person who likes things in order — my bed is always made, my room always tidy, even on holiday.
As soon as I arrived, I carefully unpacked all my belongings into this charming wooden wardrobe, quietly pleased with my organization — the kind that might impress Marie Kondo. What I didn’t realize was that, along with my three favorite cashmere pieces, I was laying out a feast for moth larvae, who didn’t hesitate for a second.
The result? My cashmere was ruined — and as an unwelcome souvenir, I brought the infestation home with me. I ended up having to completely clean out my entire wardrobe.
My advice: if you’re traveling in spring, keep your wool and cashmere safely stored in your suitcase.
Can moth-damaged clothing be repaired?
Moth-damaged clothing is not necessarily beyond repair.
Techniques such as invisible mending or darning can restore garments, sometimes seamlessly, sometimes creatively.
Considering that a single cashmere goat produces only around 200 grams of fiber per year — and the extensive process required to transform it into a finished garment — discarding such a piece due to moth damage represents a significant environmental cost.
We explore this in depth in our article on cashmere, from origin to finished garment.
When repair is not possible, textile recycling remains an important alternative. We explore this in more detail in our article on cashmere, where we look at how it is recycled in Italy — a way to extend the life of garments even beyond repair.

Preventive measures are the most effective way to deal with moths. A combination of cleaning, proper storage, and natural repellents will help protect your clothes over time.
