What to use to wash a sofa of bed bugs? - briefly
Apply a high‑temperature steam cleaner (minimum 120 °F/49 °C) with a mild detergent to saturate the upholstery, then treat the area with an indoor‑approved residual insecticide. Vacuum the sofa thoroughly after drying and repeat the process after 7–10 days to target any remaining eggs of «bed bugs».
What to use to wash a sofa of bed bugs? - in detail
Bed bugs hidden in sofa fabric require a combination of mechanical removal, heat treatment, and appropriate cleaning agents to eradicate both insects and eggs.
A thorough vacuuming of all seams, cushions, and crevices eliminates adult insects and loose eggs. Use a vacuum equipped with a HEPA filter; dispose of the bag or canister contents in a sealed plastic bag outside the dwelling.
Heat‑based cleaning proves highly effective. Portable steam generators delivering steam at 100 °C (212 °F) for at least 30 seconds per area penetrate deep into upholstery fibers, killing insects at all life stages. Follow steam application with immediate blotting using a clean, absorbent cloth to remove excess moisture.
Chemical washing agents suitable for upholstered furniture include:
- Mild detergent mixed with hot water (minimum 60 °C/140 °F); agitates and lifts debris while maintaining fabric integrity.
- Enzyme‑based cleaners formulated for protein‑based stains; break down insect exoskeleton residues and egg casings.
- Commercial upholstery shampoos containing surfactants and low‑toxicity insecticidal compounds (e.g., pyrethrin‑based formulas); applied with a soft‑brush attachment, then rinsed with hot water.
For persistent infestations, residual insecticide powders such as silica‑based diatomaceous earth or food‑grade diatomaceous dust can be dusted lightly into seams and left for 48 hours. Ensure the product is labeled safe for indoor use on fabrics and follow manufacturer safety instructions.
After cleaning, allow the sofa to dry completely in a well‑ventilated area or use a dehumidifier to reduce humidity below 50 %. Repeat vacuuming and steam treatment after 7 days to capture any newly hatched nymphs. Monitor with sticky traps placed near the sofa legs for an additional 14 days to confirm eradication.
