Care & Feeding Instructions

Do you have any advice, recommendations, tips, etc. on keeping your wool garments free from carpet beetle larvae? They are not moths but carpet beetle larvae. Any help would be greatly appreciated.

 Step-by-Step Method 

1. Clean First (important)

Wash COLD! Rinse COLD! Spin SLOW! Remove and STRETCH! 3 times every direction until the fabric quits giving. 

Brush off lint, pet hair, and debris.

• If soiled, some prefer spot cleaning before freezing.
• Larvae are attracted to body oils and food residue.

2. Seal the Garment

• Place the shirt in a zip-seal plastic bag or airtight bag.
• Remove as much air as possible.
• This prevents condensation and moisture damage.

3. Freeze

• Temperature: 0°F (-18°C) or colder
• Time: minimum 72 hours
• For heavy wool: 4–7 days is extra safe.

4. Thaw Properly

• Leave the garment sealed while warming to room temperature.
• Prevents condensation from forming on fibers.

5. Fold & Store

• Store in an airtight tub or sealed garment bag.
• Add a desiccant pack if humidity is high.

Why this Works Well

• Larvae cannot survive deep freeze.
• Eggs fail to hatch.
• No chemical residue.
• Completely scent-free.

Extra Protection Tip

For long-term storage:

✓ airtight container

✓ low humidity

✓ clean garments only

✓ occasional inspection

Optional:

• silica gel packet for moisture control
• sticky insect monitor trap nearby (odorless)

When to Repeat

If infestation was active:

• Repeat freeze cycle after 2–3 weeks to catch newly hatched larvae (rare but ultra-safe).

Bottom Line:

Freezing → sealing → proper storage is a textile-safe, scent-free, and highly effective method for protecting wool.
