Bugs and Silk: Identification, Prevention, and Protection

Silk is a luxurious and delicate fabric that unfortunately attracts various bugs and insects.

As a silk clothing enthusiast, I’ve dealt with my fair share of moth holes and carpet beetle nibbles!

Through trial and error, I’ve learned the best ways to keep bugs from feasting on my precious silks, which includes mastering proper storage methods.

In this article, I’ll share everything I know, from identifying common fabric pests, to prevention methods, signs of infestation, and how to eliminate bugs in silk.

My goal is to equip you with the knowledge to protect your investment pieces and avoid costly damage. Let’s get started!

Why Bugs Love Silk

Silk has unique properties that make it irresistible to bugs looking for a tasty meal.

The natural protein fibers provide nutrients that appeal to a variety of insects. Additionally, silk’s thin and porous weave makes it more vulnerable to attacks.

Here are three reasons moths, beetles, and other bugs zero in on silk:

  • Protein content: The fibroin protein in silk provides a nutritious food source.
  • Porous fabric: Silk’s delicate threads are full of tiny holes for bugs to chew through.
  • Perspiration salts: Human sweat lodged in the fibers contains salts and minerals that bugs crave.

Understanding what makes silk so desirable to bugs is key for prevention!

The Usual Suspects: Bugs That Love Silk

Many insects are attracted to and can damage silk garments. Below I describe the main offenders along with identifying traits:

Clothes Moths

These small tan or gray moths with fuzzy bodies don’t actually eat fabric. It’s their larvae that cause damage by feeding on silk over their 2-10 week lifespan.

Look for small holes surrounded by silk threads.

I was shocked to discover that moth larvae can eat silk, so I implemented these protective steps.

Carpet Beetles

Attracted to natural fibers and animal hair, tiny black carpet beetle larvae munch on silks, leaving small holes, usually along seams and hidden areas.

Adults are oval bugs with dark and light brown patterned wings about 1/8 inch long.


These fast-moving, silver-gray bugs eat starch, cellulose, and silk. Telltale signs are yellow discoloration and holes in fabric. They like dark, humid environments.

Signs Your Silk Has Bugs

Carefully inspecting your silk garments is key for early detection of infestations. Here’s what to look for:

  • Small holes in fabric surrounded by fraying threads
  • Trails of tiny black or brown spots indicating larva excrement
  • Presence of bugs themselves – specks crawling on the fabric
  • Shedded skins and cocoons attached to fibers
  • Staining, discoloration, bald patches

Act quickly at the first signs of an invasion to limit damage!

Protecting Silk from Bugs

Prevention is the best defense against hungry insects attacking your beloved silks. Follow these pro tips for keeping pests away:

  • Store properly: Keep silks in airtight containers to deprive bugs of oxygen. Add cedar for extra protection.
  • Inspect regularly: Check garments every 3 months for early signs of bugs.
  • Clean and air out: Professionally clean silk pieces at least once per year and air out before storage.
  • Use repellents: Place sachets with dried lavender, rosemary, mint or tobacco leaves to repel insects.
  • Control humidity: Store silks in cool, dry conditions below 65°F. Bugs thrive in moisture. Use silica gel to control humidity.
  • Use cedar: Line boxes or chests with cedar chips or blocks to repel moths. The strong scent naturally deters them.

Diligence with preventive measures will help keep your precious silks pest-free!

What To Do if Your Silk Gets Hit by Bugs

Despite your best efforts, sometimes bugs still sneak through. Don’t panic! Here are tips for dealing with the aftermath of an infestation:

  • Isolate the garment in a plastic bag and freeze for two weeks to kill bugs at all life stages.
  • Vacuum and air out the storage area to eliminate eggs and larvae that could spread.
  • Discard damaged packaging and cleaning materials in a sealed bag.
  • Inspect for staining or irreparable holes. Silk damaged over 50% may not be salvageable.
  • Take lightly damaged pieces to the dry cleaner to kill any remaining bugs through professional cleaning.
  • For valuable silk heirlooms, consult a textile restoration specialist to repair holes and tears. This specialty service can be pricey but preserves cherished items.

Act quickly to limit damage and prevent recurrence!

Can Bugs Live and Bite in Silk?

I sometimes get asked – can bugs actually take up residence and bite through silk fabric? Let’s separate fact from fiction:

Carpet beetles live and breed long-term in fabrics.Only larvae feed on materials – they don’t reside or lay eggs in fabrics.
Moths lay eggs in natural fabrics that later hatch.Adult moths lay eggs on materials but larvae hatch elsewhere before migrating to feed.
Bed bugs infest and bite through silk bedding.Bed bugs feed on blood, not fabric. They reside near hosts and won’t damage silk.

So rest assured, pests that damage silk don’t actually live, breed or bite inside the fabrics but just come to feast!

Eliminating Bugs from Infested Silk

If pests have already infiltrated your precious silks, eradication steps are needed. Here are treatment methods ranked from simplest to most extreme:

  • Freezing small items for two weeks kills all life stages of bugs.
  • Heat treating garments by tightly sealing for several hours kills bugs. Use this for heirlooms that can’t be washed.
  • Dry cleaning removes bugs and larvae while safely cleaning delicate silk.
  • Fumigation treatment at the dry cleaner involves stronger chemical agents to permeate fabrics.
  • Professional pest control heat treats or fumigates entire storage areas if bugs are widespread.

I always start with the least invasive approach and increase intensity as needed to knock out those pesky bugs!

Storing Silk: My Top Tips

After an infestation, completely clean out and sanitize your storage area before placing cleaned or treated items back. Follow these guidelines to keep silks pest-free long-term:

  • Store off the floor on shelves or in cedar lined boxes
  • Use certified airtight storage bins or garment bags
  • Place cedar blocks, dried lavender sachets, and silica gel packs inside
  • Maintain cool temperatures under 65°F
  • Inspect silk at least every 6 months
  • Professionally clean once per year

Vigilance with storage and regular inspections will help safeguard your precious silks!

Why are some types of silk more prone to clothes moths?

Clothes moths are most attracted to heavyweight silks with more gum or sericin content retaining the natural proteins that larvae feed on.

Lighter or degummed silks have less nutritional appeal. Tussah and shantung silks are especially at risk due to their coarser weaves and higher sericin levels.

What temperature kills clothes moths in silk?

Exposing infested silk garments to temperatures of 115°F to 120°F for 30 minutes kills all life stages of clothes moths.

Steam cleaning, ironing or heating garments in an oven or closed car can reach suitable temperatures. Take care not to scorch delicate silk fabrics.

Can you get carpet beetles out of silk rugs or upholstery?

Yes, you can eliminate carpet beetles from silk rugs or upholstery using fumigation or heat treatment.

Fumigation with specialized insecticidal gases permeates the materials to kill eggs and larvae hidden deep in the fibers.

Professional services are best for large or valuable silk items.

Do silverfish cause permanent damage to silk?

Yes, silverfish leave permanent fungal damage, yellow discoloration, and thinning of silk fabric.

Their chewing also causes small holes and weakened spots in silk that tend to expand over time, making the damage irreparable.

Swift removal of active infestations is key before widespread destruction.

Does dry cleaning kill moth eggs on silk clothing or fabrics?

Standard dry cleaning doesn’t always kill eggs, as they are cemented to fabrics and more resistant.

However, ask your specialist to treat silk items showing signs of infestation with spot fumigation or additional chemical agents when dry cleaning.

This permeates fabrics to destroy hidden eggs.

How can you use pheromone traps for clothes moths in silk storage?

Pheromone lures containing the synthetic version of the female moth sex hormone can attract and trap male moths when used properly in enclosed storage areas.

Traps won’t eliminate infestations but help monitor for signs of early stage activity. They’re most effective at catching stray migrating moths.

I’ve figured out how to keep silk static free and it has made wearing and storing silk so much easier.
