If you have found this article, you may be wondering, “How can I prevent my wool clothing from being eaten by insects?” If you have purchased wool clothing before and experienced insect damage, you probably want to be more careful next time. Like other types of wool, Merino wool also requires proper care to prevent insect damage.

In this article, we will explain why wool clothing can be damaged by insects and introduce practical ways to prevent it.

Why Does Wool Get Damaged by Insects?

Wool can be damaged by insects for the following reasons:

・Wool is an animal fiber that contains protein, which can become food for insects.
・The garment was stored with sweat, sebum, food residue, or other stains still on it.
・Insects attached themselves to the clothing while you were outside or while it was drying outdoors, and the garment was stored without removing them.
・The clothing was stored in an environment where insects could easily live.

Next, we will introduce prevention methods based on these causes.

How to Prevent Wool Clothing from Insect Damage

Here are the main ways to prevent wool clothing from insect damage.

Wash Before Storing During Seasonal Wardrobe Changes

Food residue and sebum stains can become food for insects. When it is time to change your wardrobe for the season, do not store wool clothing as it is. Wash it or have it professionally cleaned first.

Also, make sure the garment is completely dry before storing it. If moisture remains, it can create a damp environment where insects can live more easily.

Shake Clothing Well Before Bringing It in from Outdoor Drying

Even after washing, insects may attach themselves to clothing while it is drying outdoors. If you dry wool clothing outside, shake it well before bringing it indoors.

Use Steam from an Iron to Eliminate Insects and Eggs

Some wool products cannot be washed in a washing machine and may need to be hand washed. In such cases, dirt may not be fully removed, so using steam from an iron can help eliminate insects and their eggs.

Common clothing pests such as carpet beetles and clothes moths can lay hundreds of eggs in a single day. Use an iron carefully to help prevent insect damage.

Improve Ventilation / Open Drawers and Closets Regularly

Insects prefer poorly ventilated, humid environments with temperatures above 20℃. Once clothing is stored away, drawers and closets are often left closed until the next season. However, try opening them once a day for about five minutes to improve ventilation.

Use Clothing Compression Bags

Improving ventilation is important for preventing insect damage, but honestly, it can be a hassle. In that case, using clothing compression bags is recommended as a physical way to block insects.

Before placing clothing into a compression bag, it is important to eliminate any insects or eggs. For this reason, steaming the garment with an iron before storage is a key step.

Use Moth Repellent

Using moth repellent is also effective. Moth repellents contain ingredients that insects dislike and work especially well in enclosed spaces. There are various types, including scented and unscented options, so choose the one that best suits your preference.

What to Do If Your Wool Clothing Has Already Been Damaged by Insects

If your wool clothing has already been damaged by insects, you may be able to repair the hole through felting. If you are good at sewing, you could also remake the garment into items such as coasters, tissue covers, or stuffed toys.

If you still want to wear wool as clothing, you may need to purchase a new wool garment. If you are considering buying one, we hope you will take a look at C-one products.
