When turned on Dupray Neat steam cleaner will take up to 8 minutes to be ready to use. Once turned on the power button will be yellow and will turn into green when steam is hot enough to be used.

This device has a steam lock button. Once enabled it will produce steam continuously without you needed to keep the finger on the button. It is a very useful feature when you need to steam large surfaces such as a mattress or floor.

The electric cord holder is located on the bottom of the device. You may need to tilt it to roll up the cord before storing the device which will not be terribly convenient.

It will not be easy to determine how much water is in the boiler as there is no indicator. On the other hand, you will know that once the steam is not coming out it is time to refill. Before refilling the boiler you need to wait until the device has cooled down enough – in about 20 minutes.


  • High heat output (275°F/135°C)
  • Large boiler produces up to 50 minutes of steam
  • Built-in funnel – no need to have a separate one

The downside would be that the steam might not be able to penetrate the fabric deep enough. Therefore it is best to treat pests which are not hiding very deep in the surface such as clothes, carpets, and curtains.

How to choose the best bed bug steamer?

When selecting the best steamer to kill bed bugs, you’ll need to look for several important factors.

Heat output

This is the most important parameter when selecting the best steamer for bed bugs. Failing to reach required heat will not give any result to get rid of bed bugs.

Adult bed bugs will die at 117-122°F (47-50°C). While their eggs will require temperatures to 125°F (52°C) or more. RA Naylor and CJ Boase research has found that all stages of bed bugs were killed when exposed 140 degrees Fahrenheit (60 degrees Celsius).

Heat steamers will need to output 200-220°F (93-104°C) to reach required surface temperature. Some of the temperature will be lost when steaming bed bugs so that will be enough to reach temperature needed to kill bed bugs. Surface needs to be about 160-180°F (71-82°C) immediately after the steamer nozzle has passed the spot.

Steam pressure

Steam is very effective to kill bed bugs when they are no deeper than ¾ inches (2 cm) into the fabric surface. Within cracks and crevices steam can kill bed bugs up to 2⅜ inches (6 cm) deep.

You need to balance steam pressure for steam treatment to be effective.

Too much pressure may blow bed bugs away from the treatment area and they will survive. Too little pressure may not penetrate the surface deep enough. Some of the steamers allow you to adjust the pressure.

You need to look for a steamer which produces at least 40 PSI of pressure. If possible I would recommend choosing a device with 60 PSI of pressure output.

Drier vapor

Less water content within the hot steam is better. Too much water may ruin your furniture, floors or walls. It could also result in mold if the treatment area is left damp afterwards.

Professional steamers available on the market produce water content within the steam up to 5%.

Boiler capacity

Boiler size results in how often you need to refill the tank. The bigger the boiler the less times you need to refill during the bed bug treatment.

It will also give flexibility how much water you want to put in the tank. Bigger boiler also will result in a bigger steamer size.

For home use you will need to look for at least a 48 ounce tank to get around 45 minutes of steam. This will typically give you enough steam to treat an average mattress.

Heating time

To start treating bed bugs with the heat you need to have steam. Steam comes from boiling water. It takes some time to get the water to the boiling point.

The sooner the steamer gets water to the boiling point the better. Typical steamer takes up to 15 minutes to start producing steam. Most of the steamers on our best steamer for bed bugs list takes up to 7-8 minutes to be ready to use.

Direct injection, multiple heating elements or higher power wattage reduces time to be ready with the boiling water sooner and starting steam treatment.


Bed bugs can be hiding in the mattresses, box springs, bed frame, headboard or in cracks or crevices. To be able to treat bed bugs with steam on all kinds of surfaces effectively you need to have a wide range of attachments.

Most of the household steamers come with several nozzles to be used on furniture, mattresses, floors or tight spaces. You don’t need too many of the various attachments but rather the ones that can reach the spaces where bed bugs are hiding.

Nozzle width

Wider nozzles will require less passes over the same area in comparison to more narrow one.

Nozzles with larger steaming areas most likely will not generate too much pressure to blow the bed bugs around rather than killing them. Please do not use jet nozzles to treat bed bugs for that reason.

How to use a bed bug steamer?

You can buy the best steamer in the world for treating bed bugs for lots of money. However, if you do not know what you are doing, all that money will be wasted.

Inspect area for bed bugs

Inspect for bed bugs to find where they are hiding and how bad the infestation is. Bed bugs will typically hide on edges, seams and folds in the fabric. They also like to hide in cracks and crevices. Those are the places where you should be very carefully inspecting.

Do not move things around while you inspect to prevent unknowingly distributing bed bugs around.

Based on your findings determine the treatment area.

If you see that you have a large infestation it is better to find a professional pest control company near you. You can use our Licensed Pest Control Services Search Tool to find one in your local area.

Clean the house

Clean and declutter your home to open areas for bed bug treatment with the steam. As mentioned above, do not simply move stuff around to prevent spreading the bed bug infestation.

Any things or trash you want to get rid of toss into the trash bag and seal immediately when done. Take out the trash to avoid any pests to be transferred to another area.

Strip down the bedding from the bed and put it into the trash bags. Seal them before moving to the drying machine. You don’t want bed bugs to escape anywhere between your bedroom and the washing machine.

Once you get there put the bedding carefully into the dryer and set to the highest temperature for 30 minutes.

You may wonder why not to wash them out in a washing machine?

Dryer will dehydrate the bugs and they will be killed at high heat. In the washing machine they may not reach the temperature high enough to kill them and bed bugs might survive.

Take the empty trash bags straight to the trash can outside.

Vacuum the floor, carpet, mattress and furniture to get rid of pests, dust and debris. Remove and seal the vacuum bag (or content of your vacuum container) immediately after you are done vacuuming.

Take out the trash to avoid bed bugs or other pests in the vacuum bag to escape.

Give your house a good all-round clean up with the appropriate cleaning solution.

Setup the steamer nozzle

Depending on the surface you will be treating for bed bugs select the proper nozzle to the steamer.

For the floors or carpet select the widest nozzle that is included in the kit.

If you are going to steam the mattress or furniture then it is recommended to go for a mid-size nozzle to be able to reach into the surface enough.

When you are treating cracks and crevices you may go for the most narrow nozzle to concentrate heat in that small space and reach pests that are hiding deep inside.

Steaming ahead

Turn on the steamer and wait until the steam is ready to start the bed bug treatment. It usually takes up to 7-8 minutes.

Most importantly do it slowly to make sure the temperature of 140°F (60°C) which is needed to kill the bed bugs at any stage is reached. You should aim at the speed of 1 inch (2.5 cm) per second.

You can use an infrared thermometer to check the surface temperature and make sure the desired temperature is reached. In case you don’t have a thermometer you can touch the surface.

If it is cold — you are moving too fast and the surface is not reaching required temperature. If it is too hot and you cannot keep your hand down — you are moving too slowly and can damage the material of the surface.

Steam every inch of the mattress and box spring. Make sure you are treating edges, seams, and folds in the fabric as well as cracks and crevices very carefully.

When treating the surface with heat it is recommended to move from top to bottom. Otherwise, steam will go up and bed bugs might get away once they sense the heat.

Keep the nozzle at a bit of an angle so there is a bit of a gap at the leading edge. If you keep the nozzle flat bed bugs might sense the heat coming and get away before they get under the steamer head.

To reduce moisture from reaching the treatment surface you could add the cloth bonnet on the steamer nozzle which may be included in the kit. Alternatively, you could wrap the nozzle in a piece of cloth or towel.

I’d recommend watching this video to see the entire process of the bed bug treatment with the steamer:

Dry treated areas

After the treatment with the hot steam, you need to allow that area to dry out. You can also use a fan and raise the room temperature to speed up the drying process.

You can also install a mattress encasement to prevent bed bugs from reappearing.

Repeat the entire bed bug treatment after 7-10 days in case you will still see bed bugs.


DO NOT steam the leather because it might get damaged.

DO start steaming the area which is hidden (e.g. behind the furniture or the bottom of the dresser) so in case the surface will get damaged it is not in front of everyone’s eyes.

Our Verdict

After reviewing several best steamers for bed bugs on the market I have come to the conclusion. It wasn’t easy though.

My top #1 pick overall is Dupray Neat steam cleaner.

It has the best heat output from the all equal up to 275°F (135°C). The steamer is ready to be used in just 7 minutes after the start. With its large 54 ounces (1.6 liters) boiler tank it will keep producing steam for up to 50 minutes.

Competition for the Dupray device was quite tough. Most of the steamers I have reviewed are producing very similar results of being ready to steam in 7-8 minutes and lasting for 45 minutes.

You may consider other options than Dupray, but for now, this is my top choice for the best steamer for bed bugs.
