Avoid clothing and carpet steaming devices. These do not reach the temperatures needed to kill bed bugs.
Do not use a carpet attachment because the bristles may interfere with the nozzle getting close to the item. Do not use a pinpoint or other type of narrow nozzle as this may blow the bed bugs and their eggs around the room. [3] X Research source

Keep in mind that steaming can be a slow, tedious process, especially if you have a large area to cover. Take breaks as needed or have someone help you to prevent yourself from rushing through the job. If you come across a live bed bug while cleaning, hold the steamer over it for 30 seconds. This should be enough heat to kill it. Once the bug is dead, use a paper towel to pick it up and throw it away. [6] X Research source
Make sure to aim the fan towards the items you steamed, such as towards the ground if you steamed a section of carpet, or upwards if you steamed a chair, mattress, or box springs.
Don’t wait more than a few days to repeat the treatment because bed bugs multiply quickly!
If the temperature is below 160 °F (71 °C), then you may need to adjust your steamer or use a different steamer.
If an item gets too wet, press it with a dry towel to blot up the moisture.
Since applying insecticides can be dangerous, it is recommended to hire a professional exterminator to do this for you. They have the knowledge to choose the best chemicals for your situation and apply them safely. [13] X Research source
