How should washing be done after bedbugs? - briefly
Wash all contaminated linens, clothing, and washable items in water of at least 60 °C (140 °F) and immediately tumble‑dry on the highest heat setting for at least 30 minutes; non‑washable items should be placed in sealed plastic bags for several weeks to ensure any surviving bugs die.
How should washing be done after bedbugs? - in detail
When a bed‑bug infestation is confirmed, every washable item must be subjected to a high‑temperature wash to eradicate all life stages. Follow these steps precisely.
-
Separate items by material. Fabric that can tolerate heat (bed linens, clothing, curtains, towels) goes to the washing machine; delicate or non‑washable pieces should be sent to professional dry cleaning or bagged for freezing.
-
Pre‑treat heavily infested zones. Apply a spray containing pyrethrin or a certified insecticide, allow the label‑specified dwell time, then rinse before loading.
-
Set the machine to the hottest permissible cycle. For cotton and polyester, use at least 60 °C (140 °F). If the fabric label permits, increase to 70 °C (158 °F). Use a standard detergent; adding a small amount of enzymatic cleaner enhances egg removal.
-
Extend the wash duration. Choose a cycle lasting 30 minutes or longer; a heavy‑duty or sanitize program is ideal.
-
Immediately transfer items to a dryer. Run on the highest heat setting for a minimum of 30 minutes. The combination of hot water and hot air destroys eggs, nymphs, and adults.
-
For items that cannot be dried at high heat, place them in a sealed plastic bag and store in a freezer set to –18 °C (0 °F) for at least 72 hours. Freezing kills all stages of the pest.
-
Clean the washer and dryer afterwards. Run an empty hot‑water cycle with a cup of bleach or a commercial appliance sanitizer. Wipe interior surfaces with a disinfectant cloth.
-
Store laundered items in airtight containers or zip‑lock bags to prevent re‑infestation before they are returned to the living space.
By adhering to these procedures, the risk of remaining or re‑emerging bed‑bugs is minimized, ensuring that cleaned textiles are safe for reuse.
