How can bedbugs be removed from a blanket? - briefly
Wash the blanket in water at ≥ 120 °F (49 °C) and dry on high heat for at least 30 minutes; then vacuum the fabric and, if desired, seal it in a freezer for several days to kill any survivors. Inspect the item after treatment and repeat the process if any insects remain.
How can bedbugs be removed from a blanket? - in detail
Removing bedbugs from a blanket requires a combination of physical, thermal, and chemical methods to ensure all life stages are eliminated.
First, isolate the blanket from other laundry. Place it in a sealed plastic bag and transport it to a location where high‑temperature treatment can be applied without contaminating other items.
Thermal washing
- Use the hottest water setting the machine allows, typically 60 °C (140 °F) or higher.
- Run a full wash cycle with a strong detergent.
- Immediately transfer the blanket to a dryer set to the highest heat option (minimum 70 °C / 158 °F) and dry for at least 30 minutes. Heat at this level kills adult insects, nymphs, and eggs.
If the fabric cannot tolerate high temperatures, employ freezing:
- Seal the blanket in a waterproof bag.
- Place it in a freezer set to –20 °C (–4 °F) for a minimum of 72 hours. Prolonged exposure to sub‑zero temperatures is lethal to all stages.
For items that cannot be washed or frozen, apply targeted insecticide:
- Choose a product labeled for fabric use and approved for bedbug control.
- Follow label directions precisely, spraying both sides and seams.
- Allow the blanket to air dry in a well‑ventilated area until the chemical residue is fully evaporated.
After treatment, inspect the blanket under a bright light and magnifier. Look for live insects, shed skins, or eggs. If any are found, repeat the chosen method.
Finally, store the blanket in a sealed container or vacuum‑sealed bag to prevent re‑infestation. Regularly vacuum surrounding areas and treat adjacent furniture to eliminate residual populations.
