How to use a steam cleaner against bed bugs? - briefly
Use a high‑temperature steamer set to at least 130 °F (54 °C) and move the nozzle slowly over seams, cracks, mattress folds, and upholstery, holding each spot for several seconds to kill insects and eggs. Repeat the treatment after 5–7 days to eliminate any newly hatched bugs.

How to use a steam cleaner against bed bugs? - in detail
A steam device can eradicate bed‑bug infestations when applied correctly. Follow these steps to maximize heat penetration and minimize re‑infestation.

Select appropriate equipment

Choose a steamer that reaches at least 210 °F (99 °C) and maintains that temperature for several seconds.
Prefer models with a hose and nozzle that fit tight spaces such as mattress seams, cracks, and upholstery crevices.

Prepare the area

Remove all bedding, curtains, and removable fabrics; launder them in hot water or place them in a dryer on the highest setting for at least 30 minutes.
Declutter the room, pulling back furniture to expose baseboards, floorboards, and wall edges.
Vacuum surfaces before steaming to eliminate eggs and debris that could shield insects from heat.

Apply steam systematically

Hold the nozzle a few centimeters from the surface; avoid direct contact that could damage fabrics.
Move slowly, allowing the steam to linger for 10–15 seconds on each spot.
Focus on high‑risk zones: mattress seams, box‑spring folds, headboard joints, bed‑frame cracks, picture frames, electrical outlets, and carpet edges.
Overlap passes to ensure no gaps in coverage.

Treat hidden habitats

Insert the hose into hollow furniture legs, behind baseboards, and into wall voids if accessible.
Use a narrow nozzle for tight crevices; repeat steaming in these concealed areas three times, letting each pass dry before the next.

Post‑treatment actions

Allow treated surfaces to dry completely; heat kills insects but may leave moisture that promotes mold if not ventilated.
Re‑vacuum the room, disposing of the vacuum bag in a sealed container.
Seal or discard heavily infested items that cannot withstand high temperatures.
Schedule a follow‑up inspection after 7–10 days; repeat steaming if live insects or eggs are detected.

Safety precautions

Wear heat‑resistant gloves and eye protection to prevent burns.
Keep the steamer away from electrical outlets and flammable materials.
Ensure adequate ventilation to avoid excessive humidity.

By adhering to these procedures, steam treatment becomes an effective, chemical‑free method for eliminating bed‑bug populations and preventing their resurgence.
