What to put in clothing to protect against bedbugs? - briefly
Apply a permethrin‑based spray or soak the fabric in an approved insecticide solution, then dry it on high heat. Store the treated clothing in sealed, zippered bags and launder at 60 °C (140 °F) to eliminate any remaining bedbugs.
What to put in clothing to protect against bedbugs? - in detail
To keep garments safe from Cimex lectularius, employ a combination of physical barriers, thermal methods, and chemical treatments.
First, isolate each item in a sealed, zip‑lock bag made of thick plastic. Remove all air before sealing to create a low‑oxygen environment that discourages survival. For long‑term storage, place the sealed bag inside a secondary, heavy‑duty vacuum‑sealed bag; the double barrier prevents accidental puncture and limits exposure to any stray insects.
Second, apply heat. Wash clothing in water at 60 °C (140 °F) or higher, then tumble‑dry on the hottest setting for at least 30 minutes. Heat penetrates fabric layers and exterminates all life stages of the pest. If laundering is not possible, use a portable garment steamer; maintain steam temperature above 100 °C (212 °F) and pass the device over every surface for a minimum of two minutes.
Third, use freezing when heat is unavailable. Place garments in a freezer set to –20 °C (–4 °F) for a minimum of four days. The low temperature kills bedbugs and their eggs, provided the items remain frozen for the full period.
Fourth, treat fabrics with a residual insecticide. Apply a permethrin‑based spray according to the manufacturer’s instructions, covering both interior and exterior surfaces. Allow the treated clothing to dry completely before use. Re‑apply after each wash if the garment is laundered, because washing removes the chemical coating.
Fifth, consider specialized encasements. Commercially available bedbug‑proof covers for shirts, trousers, and jackets feature a woven fabric with a microscopic mesh that blocks insect entry while allowing breathability. These covers are especially useful for travel or for clothing stored in closets.
Finally, maintain cleanliness. Regularly inspect wardrobes for signs of infestation—small dark specks, shed skins, or live insects. Promptly launder any suspect items and repeat the heat or freezing cycle to ensure eradication.
By integrating sealed storage, heat or cold treatment, insecticide application, and protective encasements, clothing can be rendered inhospitable to bedbugs and remain safe for extended periods.
