How To Use Harris Bed Bug Killer Diatomaceous Earth Powder

Diatomaceous Earth: Natural Bed Bug Control

Bed bugs live in warm locations and often make their homes in bedding, clothes, carpets, and furniture. You, their constant supply of food, are why bed bugs enjoy these locations. To check for them, look over mattress and furniture seams and the surrounding areas for black fecal matter and blood smears.

Treat Bed Bugs With A Natural Pesticide

Diatomaceous earth is an effective bed bug powder. It’s also cheap and free of harmful chemicals. It’s easy to apply around your home and safe to apply near food, pets, and children.

Diatomaceous earth (DE) kills bed bugs by absorbing the oily, protective layer that covers their exoskeletons. Without this protective coating, bed bugs will dehydrate and die within a few hours.

How Do I Treat for Bed Bugs?

Effective natural bed bug treatment comes down to six simple steps:

  1. Steam Clean Your Home
  2. Wash All Fabrics
  3. Vacuum Your Home
  4. Apply Diatomaceous Earth
  5. Clean Up
  6. Repeat as needed

Shop Food Grade Diatomaceous Earth

Before beginning, bug proof your home by sealing up any places bed bugs could enter, such as cracks or crevices.The chances of re-infestation are much lower if you do this first.

Step 1: Steam Clean Your Home

Bed bugs cannot survive in temperatures above 130 degrees fahrenheit for more than a few hours. Steam clean your linens and furniture thoroughly with a steam cleaner to increase the temperature.

Step 2: Wash All Fabrics

Put all fabrics through the wash on very high or very cold temperatures. Dry on a high heat and store all washed fabrics in sealed plastic bags or containers.

Step 3: Vacuum Your Entire Home

Vacuum your carpets thoroughly. If possible, also use a carpet cleaner to remove any bed bugs from the carpeting.

Dismantle furniture as much as possible and vacuum every surface, paying particular attention to your furniture’s seams and frames. Get tight spots with your vacuum’s hose attachment. After vacuuming, you may reassemble your furniture. Consider using a total encasement mattress cover on your bed.

Step 4: Apply Diatomaceous Earth

Diatomaceous earth works as both a tool for prevention and treatment. Apply DE by following these steps:

  1. Find areas around your home where you suspect bed bugs may be hiding or may return to.
  2. Use an applicator to apply diatomaceous earth along moulding, in drawers, in any cracks or crevices, behind appliances, along windowsills and door jams.
  3. Remove all electrical faceplates and use an applicator to puff DE behind electrical switches and outlets.
  4. Cover furniture and mattresses with a thin layer of DE and work it into the furniture, mattresses, and carpeting with your hands.

Step 5: Clean Up

We recommend leaving the diatomaceous earth applied as long as possible. Although it’s far from a fashion statement, keeping a constant barrier down against bed bugs will help ensure your victory. Even though DE can kill a bed bug in a few hours, it might take a long time for all the bed bugs to be exposed, and DE only affects adult bed bugs, so you have to leave it applied long enough for the bed bug eggs to hatch.

After a couple weeks, you can wipe it all off and vacuum it up. A word of warning here: diatomaceous earth is very hard on traditional filtered vacuums. Unless you’re only cleaning a small section, we recommend using a shop vac to avoid burning out your vacuum’s motor. For more information on cleaning up diatomaceous earth after you’ve applied it, check out our DE clean-up article here.

Step 6: Repeat as Needed

If the bed bugs persist, don’t lose hope. Repeat the steam cleaning, vacuuming, washing, and applying diatomaceous earth until the problem subsides.

Follow these steps in every part of your home. Repeating these steps is necessary to break the cycle of infestation. If you continue to use diatomaceous earth in your home, it will help prevent future infestations.

Stacy – February 14, 2020

Have had powder on chair for about 4 days now and still getting bit. Should i take apart and steam inside?

Riley Sizelove – February 15, 2020

I recommend puffing the powder in areas bed bugs are suspected of traveling. The idea behind the powder is to get the bed bugs to crawl through it. In conjunction with the powder, I would recommend using a spray and an aerosol. The spray maintains a residual while the aerosol kills the bed bug eggs. All three are paramount in ridding of an infestation and suggested by the EPA as IPM or integrated pest management.

Do you make foggers for bed bugs

Riley Sizelove – February 27, 2020

We do sell a generic fogger that some customers will use to help rid of bed bugs, however, a more effective treatment is using our EPA registered diatomaceous earth powder, a strong bed bug liquid (black or gold label) as well as an aerosol spray to ensure the bed bug eggs are killed as well during treatment.

Please let us know if you have any questions.

Will this powder kill bed bug eggs as well as live bed bugs? Is your only egg killing product the Egg Kill spray?

Admin Riley Sizelove – March 13, 2018

The powder only works when Bed Bugs crawl through the powder so an Egg would not have the same exposure and we do not make that claim on the label.

Riley: I’m trying to find directions somewhere health precautions. When is it safe to again sleep on a mattress that has been dusted with the powder…things like that.

Admin Riley Sizelove – March 19, 2018

I believe you may be referring to the Bed Bug Powder. This product would be applied to the folds and edges of the mattress and box springs. Remember to use in moderation; no need to use excessive amounts. The bed may then be re-dressed (mattress pad, sheets etc.) and used immediately. The powder dehydrates insects that come in contact with it and it is intended to by applied and left in place for an extended period of time. It keeps killing insects for weeks. It is a natural product. Just not intended for direct skill contact surfaces to avoid any possible skin irritation. Thank you.


Michelle – August 19, 2018

Had bed bugs in mattress box spring bagged and threw out its only one room upstairs iv dusted everything it’s been a week how long should I leave it closed up

Admin Riley Sizelove – August 20, 2018

Bed Bugs can live quite sometime without feeding – I would leave the mattress encasements on the mattress and box spring for at least 6 months.

How to Effectively Kill Bed Bugs Using Diatomaceous Earth (DE)

Food grade diatomaceous earth is a natural non-toxic method to kill bed bugs and prevent them from invading your home. Diatomaceous earth (DE) powder is a naturally forming substance that helps to get rid of bugs quickly and effectively. One of the benefits of using this white powder for killing bed bugs is that it won’t harm humans or pets. Bed bugs can be difficult to eradicate from your home and you can use diatomaceous earth together with other bed bug extermination methods to get rid of the critters for good.

The abrasive action of diatomaceous earth powder destroys the bed bug’s exoskeletal system. The abrasion on the outer layer of these tiny pests causes them to dehydrate and very soon your bed bug problem will be gone for good. So, if you notice tiny black specks around your headboard, bedding, and in the corners of your mattress, you should think about using DE to kill off the infestation of bugs around your bed.

This article looks at how to use food grade diatomaceous earth as a natural pest control for bed bugs. You will also learn about bed bug infestation signs and when you should use DE or other bug control methods to eradicate the problem.

First of all, let’s look at what diatomaceous earth is and why diatomaceous earth is effective for killing off groups of bed bugs and preventing them from infesting your home.

What is Diatomaceous Earth (DE)?

Diatomaceous earth is a natural substance from the fossilized remains of diatoms – a type of algae. This is ground into a powder or dust to be used as a non-poisonous way to kill mites and insects.

The National Pesticide Information Center (NPIC) says that food grade diatomaceous earth isn’t toxic when ingested. DE eliminates bugs and fleas by drying out their exoskeleton which causes them to dry out and die. However, for diatomaceous earth to remain an effective bug control method, it needs to be kept dry. 1

What Kind of Diatomaceous Earth to Use for Bed Bugs?

Diatomaceous earth dust that you use to kill bed bugs should be classed asfood grade(here isone example). The NPIC says that food grade DE has been purified and will not cause problems to humans and pets if ingested.

However, diatomaceous earth can cause some irritation to your lungs and respiratory system, so you should still wear a dust mask and clothing to protect your skin – especially if you have a large bed bug infestation and regularly use DE. The NPIC says that breathing in DE may cause irritation in the nose and eyes and may give you a cough and shortness of breath. 1

How Diatomaceous Earth Effectively Kills Bed Bugs

Diatomaceous earth has been used as a non-toxic pesticide since the 1960s. The destructive action of DE on bed bugs causes them to die after a few days of exposure.

According to Prof. Stuart Hill from the Department of Entomology and Ecological Agricultural Projects, food grade diatomaceous earth is an ideal pesticide for removing bed bugs from the home. Comparing toxic chemicals with DE, Prof. Hill said that the repellent nature of chemicals is short-lived, whereas DE is effective on bugs for as long as the dust is on the critters. 2

The journalInsectsin 2016 published a study into the effectiveness of diatomaceous earth dust for bed bug control. It was reported that diatomaceous earth could kill off 100% of bed bugs in a 9 to 15-day period. DE was also effective in eradicating bed bugs that had become resistant to chemical pesticides. 3

Therefore, because diatomaceous earth uses “mechanical” action to destroy bed bugs and other insect pests, it can safely be used around the home to control a bug infestation. Diatomaceous earth can also be used as a natural ant repellent and help rid your home of cockroaches. In fact, food grade diatomaceous earth is safe enough to ingest and get rid of intestinal parasites.

Signs of Bed Bug Infestation

To use diatomaceous earth to kill off all bed bugs in your home, it’s important to know about the life cycle of the tiny bugs and spot signs of a bedbug infestation.

Dr. Carol DerSarkissian on WebMD says that bed bugs are about the size of an apple seed and scurry over floors, walls, and ceilings. Bed bugs love to hide in dark places and are commonly found in mattresses, headboards, box springs, and in the nooks and crannies of bed frames. They come out at night to feed on blood and that is why, if you have a bed bug problem, you may notice tiny blood stains that look like black specks on your bed linen or pillow. 4

The symptoms of being bitten by bed bugs are red itchy spots on your body. Dr. DerSarkissian says that the tiny bugs generally bite around the ankles, but will pierce any part of the skin to gorge on blood. The bites can turn into red bumps on your skin that cause mild to severe itching on the affected part of the body.

Researchers from Purdue University say that other signs of a bed bug infestation are dark spots that are fecal matter around bed frames, on mattresses, and sheets. You may also notice shed skins or tiny eggs around areas where they like to hide. There may be a distinctive odor also. 5

How to Use Diatomaceous Earth for Killing Bed Bugs

Let’s look at the steps to use diatomaceous earth powder as a bed bug killer. This next section examines how to apply diatomaceous earth for bed bugs and what precautions you should take when using bed bug powders.

Step 1 – Find the Infestation

The first step to completely eradicate bed bugs from your home is to find out where the annoying pests are hiding.

Researchers from Texas A&M University say that usually bed bugs are found infesting bedrooms or other rooms where people sleep. So, you should look for signs of bug infestations around beds, mattresses, sofas, and sofa beds. 6

You should vacuum all areas of your home that show any signs of bed bugs inhabiting the furniture or bedding.

To help know where exactly to dust diatomaceous earth for bed bug control, the Department of Entomology at NC State University recommends examining the following places: 7

  • Carefully inspect all furniture.
  • Check all holes and slots of beds and dismantle the bed frame if necessary.
  • Check the seams of mattresses and pillows for bed bug feces and other signs of infestation.
  • Look behind drawers, under chairs, behind pictures, and behind dressers and closets.
  • Inspect behind the cover of electrical outlets.
  • Check cracks in baseboards.
  • If you have recently returned from vacation, thoroughly inspect all luggage and clothing that you had with you.

Step 2 – Encase the bed bugs

Before using DE for getting rid of bed bugs, you should encase any mattresses where you suspect bed bugs are hiding.

For this, you can purchase specially designed bed bug encasements that will prevent the bug escaping from the mattress, pillows and other bed linen placed in it (here is one example). Because the bed bugs don’t have any source of blood, they will eventually die off and no longer become a problem.

You should also wash your bedding in hot water and put in the dryer for at least 30 minutes to make sure that all bed bugs have been killed.

You can also use hot steam as an effective home remedy to eradicate bed bugs and you can use it after vacuuming. The hot steam can eliminate bed bugs from small crevices and cracks. It can also penetrate through the mattress lining and eradicate bug infestations inside the mattress.

Another thing that you may want to try is placing bed bug traps (such as this one) under your bed legs to stop bed bugs crawling up.

The next step is to use food grade diatomaceous earth to kill the bed bugs from furniture, beds, and other hiding places where they live.

Step 3 – Use DE to Kill Bed Bugs

Now is the time to put the bed bug killing power of food grade diatomaceous earth to work. This is what you should do to exterminate all traces of bed bugs from beds, sofas, and other furniture.

  1. Make sure that all areas are absolutely dry and free from moisture.
  2. Lightly dust all affected areas with diatomaceous earth powder.
  3. You can also dust over carpets, baseboards, pet’s bedding, pillows, and other soft furnishings.
  4. After 2 or 3 days, vacuum the area to get rid of any bug larvae, dead bed bugs, or eggs.
  5. Repeat the process of dusting diatomaceous earth powder on affected areas until all bed bugs are completely gone.

It will take some vigilance on your part to completely exterminate all traces of bed bugs from your home. You should also remember to continue using diatomaceous earth for a week or so after you are sure that the bed bugs are gone. This is to ensure that you have no further infestation from eggs that may have hatched during that period.

Safety Precautions When Using DE for Bed Bug Extermination

Although you can use food grade diatomaceous for bed bug killing liberally around the home without fear that it is toxic to humans and pets, there are some precautions you should take when using it.

Because diatomaceous earth powder is a very fine abrasive dust, therefore, you should avoid inhaling it. Prof. Stuart Hill advises using a dust mask to prevent inhaling diatomaceous earth if you are treating a large area of bed bug infestation. However, there are no other health risks reported with using food grade DE around the home for pest control. 2

Other Natural Ways to Get Rid of Bed Bugs

There are other natural ways to get rid of bed bugs that are non-toxic and safe to use in the home.

Tea tree oil. Some people have had success with using tea tree oil as a bed bug repellent and natural insecticide. A study in the journalMedical and Veterinary Entomologyfound that tea tree oil was effective at killing off various insects and also had a repellent effect. 8

You can make your own natural insecticidal spray by filling a spray bottle with water and adding 20 drops of tea tree oil. Shake well and apply to all parts of the bed where you think bed bugs are lurking. Just remember, not to spray onto areas treated with diatomaceous earth as the liquid will cause DE to become ineffective.

Tea tree oil has another use in your battle with bed bugs and the irritation they cause. Tea tree oil contains antimicrobial and anti -inflammatory properties that can help to treat bed bug bites. All you need to do to reduce itching from insect bites is this: put a drop or two of tea tree oil on the end of a cotton bud and dab this on the itchy bed bug bumps as a spot treatment. Tea tree oil is one of the best natural treatments for bed bug bites as it kill off any germs that may cause infection.

Use bed bug sprays. There are effective DIY and commercial bed bug sprays that contain natural ingredients. You can find out how to make and use these sprays in my article about the most effective bed bug sprays.

Extreme temperature. Researchers from the New Jersey Agricultural Experiment Station recommend laundering bed linen in hot water and then drying them in a hot dryer to kill bed bugs. Also, you could put small items of bedding like sheets, pillows, and pillowcases in the freezer for 4 days.

How to Prevent Bed Bug Infestations

The best way to make sure that you never have any bed bug problem is to prevent these nasty critters from infesting your home in the first place. Here are some effective tips on how to prevent bed bug infestation.

  • If you see dark marks or blood spots on your bedding, immediately check all areas of your bed, mattress, and bedding for signs of bed bugs.
  • When staying in hotel rooms, use a flashlight to inspect the bed frame and mattress for signs of bed bugs.
  • Before bringing in second-hand furniture, beds, or mattresses to your home, thoroughly examine the items to make sure there are no bed bugs in corners, joints, and seams.
  • Vacuum your luggage after returning from vacation.

Diatomaceous Earth for Bed Bugs-How to Use & Best Reviews

A number of authentic sources indicated that diatomaceous earth commonly known as bed bug powder can be an effective remedy for getting rid of bed bugs. Read on find out how it works, how to use it safely and the best and reviews.

Diatomaceous earth bed bugs Treatment

It is a naturally occurring substance that emanates from the sedimentary rock. The rock often crumbles into fine white powder. The powder has a feel of abrasion and it is light because it is highly porous.

The diatomaceous signifies remains of fossils of the long dead aquatic organisms that are known as diatoms. Theses remains are made up of silica which is one of the commonest natural substances. Diatomaceous is a very effective home remedy for the elimination of bedbugs.

Getting rid of bedbugs invites the thought of the use of very hazardous chemicals. The challenge is that the chemicals make the problem even worse or don’t work at all. Basing on research, Diatomaceous is a fantastic possible natural remedy that is suitable for bedbugs.

According to Changlu Wang, Timothy Gibb, and Gary W. Bennett from Purdue University, diatomaceous earth is an excellent remedy in getting rid of bedbugs from infested apartments. This is based on their various tests that they carried out.[1]

How does powder/dust kill bed bugs?

It is very easy and straight forward to use this powder for bed bug elimination. All that is needed is a small amount of the powder and an applicator. You will not be required to add any chemical or any other ingredient for it to work. Apart from being effective, it is also cheap when compared to other methods.

Each particle of the diatomaceous earth has small/microscopic sharp edges. When you expose bedbugs to these edges, their exoskeletons get eviscerated. Because of the drying action of the diatomaceous earth, the bedbugs dry out and then finally die.

The biggest advantage of using diatomaceous earth is that it works by physically killing the bedbugs. This implies that there is no risk of toxicity that can come with the use of chemicals. The earth also works for a longer time without losing its killing power.

Effectiveness-How long/fast does it take?

Diatomaceous earth can stay for a long time without losing its potency. You can use the Earth because it sets up barriers against the bedbugs.

This therefore implies that it is very effective. It is hard in this case for the bedbugs to develop resistance as in the case of chemical treatments. Once you apply the Diatomaceous earth, it will work for the entire time.

After applying the DE on the infested area, it begins to absorb the body fluids of the bedbugs but will not let the bedbugs go until they are dead. There are pesticides that may chase the bed bugs but the bad news is that they are bound to return.

The use of a professional bedbug exterminator costs about $500 to $1,500. The use of a bedbug heater is also expensive. It will cost about $300. On the other hand, a diatomaceous earth costs about $20.

How to use diatomaceous earth for bed bugs

Dematiaceous Earth is very safe when used. You should be careful to put on a mask so as to avoid inhaling the dust. The following is a short procedure which you should follow when dealing with the bedbug nightmare:

  1. Apply the Diatomaceous Earth to the areas that are infested by the bedbugs i.e. walls, cracks, door jams and even rung holders. In this case, you could use an applicator stick
  2. Then, remove electrical faceplates and go ahead to use an applicator to introduce the DE behind switches of electricity and sockets.
  3. It is good for you to use the DE for about a week. Afterwards, you can remove this from the site by the use of a dump cloth, a vacuum without a filter or a broom. Be careful when using the vacuum filter because the DE is abrasive and may damage it.

Alternatively, the following stepwise approach is also useful:

  1. To begin, steam your home using a steamer. This is because the bedbugs cannot survive at a temperature above 130 degrees Fahrenheit for even a few hours. Also, you can go ahead and steam clean the furniture and all the linens.
  2. After that, wash all your fabrics using very high or very low temperatures. Having done that, dry it on high heat and then store the fabrics in plastic bags that are sealed.
  3. The next step is to vacuum your entire home. Give the carpets more attention and vacuum them thoroughly. Dismantle your furniture as much as you can and then vacuum them especially along the seams and the frames. Only reassemble your furniture after completely vacuuming your entire house.
  4. Your home is now ready for applying diatomaceous earth. The earth will work as a preventive and treatment remedy. Apply the earth using the steps outlined above.
  5. Finally, clean up the entire operation surface. It is recommended that you leave the diatomaceous earth for as long as possible. The DE kills bedbugs within a short time, but it might take a while for all the bedbugs to get exposed. It also might take time because the powder only handles adult bedbugs and spares the young ones. This therefore should justify the reason for adequate time is required.
  6. In the event that the bugs persist in terrorizing you, then it is prudent to repeat the steam cleaning, vacuuming, washing and application of the diatomaceous earth till the bugs are out of your sight. This prevents any future infestations.

The main idea to the application is to make the movement of the bedbugs impossible by spraying the DE on their paths. The following are some of the tips that you can use so as to get the best results when applying the diatomaceous earth.

  • Ensure that the DE is in very fine powder i.e. micronized. Bedbugs would comfortably walk on large sized DE.
  • Only use small amounts of the DE. Large amounts would make the bedbugs to spread about and thus cause more harm.
  • Only apply the powder on areas that cannot be blown out by the air.
