Bed bugs are among the toughest pests to deal with. Although they don’t spread any diseases to humans or pets, these insects are hard to live with. They bite at night while we sleep and can be embarrassing when you have guests over.
What’s worse is that your house doesn’t even need to be filthy to invite a bed bug invasion. A single pregnant female hitch-hiking on your pants leg could lead to a full-blown infestation within a few short months. These critters can live for a few months without having a blood meal so leaving your home temporarily in the hope that they will starve to death is not an option.
Heat Treatment for Exterminating Bed Bugs: Our Top Picks
Heat treatment is a common method that pest control professionals use to eliminate bed bugs. If applied correctly, steam can kill bed bugs in all stages of development.
Bed bugs cannot survive at temperatures above 119 °F while the eggs die at temperatures above 125°F. You will need to maintain this temperature for at least 20 minutes, preferably for up to 3 hours.
For a steam treatment to be effective, you will need to hit a surface temperature of between 160°F and 180°F on the area you are treating so an infrared thermometer will come in handy.
The high temperature should exterminate the bed bugs and their eggs on contact so there is no need to maintain the temperature for a long time once you hit it.
A good steamer will treat bed bugs up to ¾-inches inside the fabric’s surface and up to 8-inches deep in gaps and crevices. If you’re steaming your clothes to kill bed bugs, then your steam won’t have to travel very far so the output distance won’t be as important.
Here’s our top-ranked bed bug steamers, in order.
What to Look for in a Steamer for Bed Bugs
It’s important to note that there are not necessarily steamers specifically designed to exterminate bed bugs. A home-use steamer that meets the criterion we have outlined below should work fine for small to medium-size bed bug infestations, which is excellent because you can continue using the product for other purposes as well.
Probably the most important consideration for a steamer for treating bed bugs is its ability to produce hot steam. You need a steamer with an output of at least 200° F to hit the minimum surface temperature required to eliminate the bed bugs.
Some of the heat will be lost while steaming so your steamer must have a higher heat output than the target temperature needed to kill bed bugs.
You want to be able to treat bed bugs inside fabrics and in crevices so high steam pressure will ensure that the heat reaches the pests where they are hiding. Bed bugs rarely stay on the surface so you will need all the pressure you can get.
The steam pressure also affects how hot and dry the steam gets. Go for at least 40 PSI, preferably 60 PSI.
Heat-treating bed bugs is hard work and you don’t want to have to refill your steamer any more than you need to. A steamer with a large water capacity will give you more continuous steam time and reduce the number of breaks you have to take to refill your unit.
A knob for adjusting the steam pressure on your steamer will come in handy when you find bed bugs on open surfaces. The high steam pressure you use to reach inside crevices will most likely blow the bed bug away rather than killing it on contact.
Adjusting the steam pressure will also allow you to get deeper into fabrics and crevices.
Once again, heat-treating bed bugs is not an easy or desirable job. The sooner you can get it over with the better. The typical steamer requires up to 15 minutes to boil water before it can produce steam. Shortening this time frame means you can get through your task quicker.
Steamers with higher wattage, direct injection and/or multiple heating elements tend to be quicker in this regard.
You want a versatile steamer that you can use on different floor types and fabrics. More attachments typically mean you can treat more areas effectively.

Step-by-Step: How to Get Rid of Bed Bugs with a Steamer
Heat-treating bed bugs with steam is a great way to get rid of the nasty pests and is best used with complementary extermination methods or as preparation for when the pest control professional arrives.
1. Do a Thorough Bed Bug Inspection
It helps a great deal if you know exactly what you will be treating beforehand. Do a full inspection of the house, paying attention to where bed bugs like to hide including inside mattress stitching, in the box spring, and on pillows, cushions, and sheets. Also, inspect all your furniture and carpeting since bed bugs have a tendency to spread quickly especially in the case of a large infestation.
2. Clean the House Thoroughly
Clean the house thoroughly to minimize bed bug hiding places. Clear out the clutter and vacuum your mattresses, furniture, and carpets to get rid of dirt and debris. You may also get lucky and suck up a good number of these pests.
You may also want to consider treating your car for bed bugs while you’re at it.
3. Attach the Steamer Nozzle
The best nozzle to use for steaming bed bugs is the triangular nozzle that comes with the steamer. This nozzle gets close to the surface and heats it sufficiently while also covering a wide surface area to make your job quicker.
Use a microfiber cloth with your triangular attachment if you have one. The microfiber cloth helps to direct the steam to the precise area you are steaming.
4. Start Steaming
Once the steamer has heated up and is ready to go, point the nozzle into a container and start the steamer to get rid of any water. Now you can start steaming.
Work slowly to make sure that the surface has enough time to heat up and that the steam penetrates into the fabric or crevice. Use your infrared thermometer to ensure that you reach the optimum temperature before moving on to the next section.
Alternatively, maintain a slow pace of roughly 12 inches per 30 seconds to make sure you get the bed bugs. The steam cleaner should be on low or medium pressure to avoid blowing the pests away.
Follow the steamer’s instructions on how to relieve pressure and cool the steamer once you are finished.
5. Dry the Treated Areas
Allow the treated furniture and fabrics to dry out or use a fan to speed up the process. Consider wrapping your treated box spring and furniture in thick plastic for at least two weeks to ensure that any surviving pests are killed.
At the very least, consider installing a bed bug mattress encasement to protect the treated mattress from infestation until the bed bug problem has been solved permanently. .
Repeat the process after one week if you can still see bed bugs.
Final Thoughts on Steam-treating Bed Bugs
Keep in mind that only the bed bugs that have come into contact with the steam will die. Avoid using a pin point nozzle since this attachment can blow away the bed bugs rather than killing them.
Use protective clothing and eye protection. Stream cleaners get very hot and can cause severe burns on exposed skin. Most of all keep the equipment well away from small children and pets, especially when in use to avoid potential accidents.
