How to treat blankets for bedbugs? - in detail
Bed‑coverings that harbor Cimex lectularius require prompt, thorough decontamination to prevent re‑infestation. Begin by removing the items from the sleeping area and sealing them in a heavy‑duty plastic bag to contain any escaping insects.
- Hot water wash – Set the washing machine to at least 60 °C (140 °F) and run a full cycle with detergent.
- High‑heat drying – Transfer the blankets to a dryer set to the highest temperature for a minimum of 30 minutes; heat kills all life stages.
- Isolation – If the fabric cannot withstand high temperatures, place it in a sealed bag and store it in a freezer at –18 °C (0 °F) for at least 72 hours; prolonged freezing eliminates bed bugs and eggs.
When laundering is impossible, apply residual insecticide powders or contact sprays approved for fabric use. Follow label directions precisely, ensuring even coverage on both sides of the blanket. After treatment, store the item in a sealed container for several weeks to monitor for any surviving insects.
Steam penetration offers a chemical‑free option. Use a handheld steamer that reaches 100 °C (212 °F) and apply steam slowly, maintaining contact for at least 10 seconds per area. Focus on seams, folds, and stitching where bugs tend to hide. Allow the blanket to dry completely before reuse.
Professional heat‑treatment services can raise the temperature of entire blankets to 55–60 °C (130–140 °F) for a sustained period, guaranteeing eradication without fabric damage. This method is especially useful for delicate or large items.
To reduce future risk, keep blankets folded and stored in airtight containers, inspect them regularly for signs of activity, and avoid placing them directly on infested surfaces. Combine these practices with regular room treatment for comprehensive control.
