How to launder to remove bedbugs? - briefly
Wash infested fabrics in water of at least 120 °F (49 °C) for 30 minutes, then tumble‑dry on the highest heat setting for another 30 minutes. Seal the cleaned items in airtight bags until the heat cycle finishes to avoid re‑infestation.
How to launder to remove bedbugs? - in detail
Washing infested textiles is one of the most reliable ways to eradicate bedbugs. The process must combine high temperature, appropriate detergent, and thorough drying.
First, separate items that can be laundered from those that cannot. Place all washable fabrics—sheets, pillowcases, clothing, curtains, blankets—in sealed plastic bags before transport to prevent insects from escaping.
Use the hottest setting the fabric can tolerate. For cotton, linen, and most synthetics, set the washing machine to at least 60 °C (140 °F). If the garment label permits, raise the temperature to 70 °C (158 °F) for added certainty. Select a regular or heavy‑duty cycle lasting a minimum of 30 minutes; longer cycles increase exposure time.
Add a standard laundry detergent. For extra assurance, include a small amount of an insecticidal soap that is safe for fabrics. The detergent helps dissolve the waxy coating that protects bedbug eggs.
After washing, transfer items promptly to a dryer. Dry on the highest heat setting for at least 30 minutes. High‑temperature air kills both adult insects and eggs. If the dryer lacks a high‑heat option, use a professional dryer service that can reach 70 °C (158 °F).
For items that cannot withstand high heat, use alternative methods:
- Soak in hot water (≥ 50 °C / 122 °F) for 30 minutes, then press with a steam iron set to maximum temperature.
- Place in a sealed bag and expose to a portable steam generator for 10 minutes, ensuring steam penetrates all layers.
- Freeze at –20 °C (–4 °F) for 4 days; low temperature kills bedbugs but does not affect most fabrics.
Inspect each cleaned item before returning it to the bedroom. Fold or store in airtight containers to prevent re‑infestation.
Finally, clean the washing machine and dryer interiors. Run an empty hot cycle with a cup of white vinegar or a commercial laundry sanitizer to remove any lingering insects or eggs.
Following these steps eliminates bedbugs from laundered materials and reduces the risk of spreading the pest to other areas.
