How to get rid of bedbugs on silk and wool

Standard bedbug treatments like hot washing and high-heat drying destroy delicate materials like silk, merino wool, and lambswool. This leaves travelers with valuable wool sweaters and gear trapped between risking permanent fabric damage or failing to fully disinfect their clothes.

What people tried

Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.

  1. 1
    Spraying synthetic gear with permethrin
  2. 2
    Freezing items at -20°C (-4°F) for at least a week
  3. 3
    Baking items in an oven at 60C / 140F to avoid tumbling damage
  4. 4
    Encasing delicates in plastic for a period of time instead of heat treating
  5. 5
    washing the wool on cold with a gentle detergent and inspecting closely for holes before drying

“every single place I have stayed north of Esposende has had bedbugs.”source ↗

“most of my gear is silk, synthetic, or merino. Synthetic is easy: just spray with permethrin when you get back. Silk and wool, however?”source ↗

“I know these items can’t be washed on hot and then dried on high. Can they go straight into the dryer on hot? Or does anyone know of a silk-safe bedbug disinfecting spray?”source ↗

“i’m quite worried about the condition of the clothing in there. i’m okay with saying bye to everything in there except one item. i believe there to be a lambswool sweater from the brand Pleasing in there. i love that sweater to pieces and would be absolutely devastated to lose it.”source ↗

“idk how to approach cleaning the clothes in these bags, or what i should look for on the clothes.”source ↗

“i’m worried that the sweater will show signs of pests, i don’t even care about anything else in those bags at this point, i only want to save the sweater.”source ↗
