How to wash bedding to remove bed bugs? - briefly
Wash the bedding in the highest temperature the fabric allows, using a detergent and a wash cycle of at least 30 minutes, then tumble‑dry on high heat for a minimum of 30 minutes to eliminate all life stages of bed bugs.
How to wash bedding to remove bed bugs? - in detail
Cleaning linens to eradicate bed bugs requires precise temperature control, appropriate chemicals, and strict handling to prevent re‑infestation. Begin by sorting all fabric items—sheets, pillowcases, blankets, duvet covers, and pillow protectors—into a single load. Separate any non‑washable accessories, such as mattress pads, for alternative treatment.
- Use water that reaches at least 49 °C (120 °F). Most residential washers achieve this on a “hot” or “sanitize” setting; verify the temperature with a thermometer if possible.
- Add a high‑efficiency detergent. For white or color‑fast fabrics, incorporate a chlorine bleach solution (up to 5 % concentration) to boost mortality. For delicate or colored items, use an oxygen‑based bleach to avoid fading.
- Run a full‑wash cycle with an extended soak of 15–30 minutes before the main agitation. This allows the chemical to penetrate cracks where insects hide.
- After washing, transfer the load immediately to a dryer set on the highest heat option, reaching at least 54 °C (130 °F). Maintain this temperature for a minimum of 30 minutes; the combined effect of heat and tumbling kills both adult bugs and eggs.
If the dryer cannot sustain the required heat, place the laundered items in sealed plastic bags and expose them to a commercial dryer‑grade heat chamber or a professional steam treatment.
Post‑laundry steps are essential to avoid re‑contamination:
- Vacuum the mattress, box spring, and surrounding area with a HEPA‑rated vacuum; discard the bag or clean the canister promptly.
- Encase the mattress and pillows in certified bed‑bug‑proof covers, sealing them with a zippered closure.
- Store cleaned linens in airtight containers until the infestation is confirmed eradicated.
Repeat the washing process after a two‑week interval, as newly hatched nymphs may emerge from surviving eggs. Consistent application of high‑temperature laundering, thorough drying, and environmental sanitation eliminates the pest population and prevents recurrence.
