Wash pillows and blankets in water at ≥120 °F (49 °C) for at least 30 minutes, then dry on high heat for 30 minutes; alternatively, seal them and expose to ≥118 °F (48 °C) for 90 minutes or freeze at –4 °F (–20 °C) for four days.
How should I treat pillows and blankets for bed bugs? - in detail
Treat pillows and blankets as potential reservoirs for bed‑bug infestations. Begin by isolating them from the rest of the household. Place each item in a sealed, heavy‑duty plastic bag or vacuum‑sealed cover that can withstand heat.
Heat treatment is the most reliable method. Use a dryer on the highest setting (≥130 °F / 54 °C) for at least 30 minutes. Verify that the fabric can tolerate that temperature; for delicate items, consider a professional steam‑cleaning service that reaches 212 °F (100 °C) for a minimum of 15 minutes.
If heat is unsuitable, apply a cold‑kill protocol. Seal the textiles in airtight bags and store them in a freezer at −4 °F (‑20 °C) for a minimum of four days. This temperature kills all life stages of the insects.
Chemical options should be limited to products approved for use on bedding. Apply a residual insecticide spray labeled for fabric use, following the manufacturer’s dosage and safety instructions. Ensure even coverage on seams, folds, and stitching. Allow the product to dry completely before re‑covering the items.
After treatment, inspect each pillow and blanket for live insects or shed skins. Use a flashlight and a fine‑toothed comb to examine seams and folds. Replace any item that shows signs of damage or persistent infestation.
Finally, maintain protection by encasing pillows and blankets in zippered, insect‑proof covers. Wash covers regularly in hot water (≥120 °F / 49 °C) and dry on high heat. Rotate or launder bedding weekly to prevent re‑establishment of the pest.
