CimeXa Insecticide Dust

CimeXa Insecticide Dust is the newest product available in the battle against bed bugs, fleas, ticks and other insects.  CimeXa Dust is 100% Silica dust, is very safe, odorless, and will not stain.  CimeXa Dust will last up to 10 years when applied to undisturbed areas like wall voids. It is very effective on bed bugs, fleas, and especially pyrethroid resistant bed bugs. When pests come into contact with CimeXa, the product clings to their exoskeleton and absorbs the waxy coating, causing death from dehydration.

How CimeXa Insecticide Dust Works

CimeXa Insecticide Dust contains 100% natural silica gel which kills insects by contact. When insects pick up the dust on the exoskeleton, it clings to and absorbs the waxy coating, causing dehydration and eventual death. CimeXa is best applied with a duster to avoid over-application. Because of its mode of action, CimeXa Dust takes longer to kill target pests. However, the natural ingredient has no properties that cause it to change or break down, so the dust is effective for at least 10 years when applied in undisturbed areas.

CimeXa Insecticide Dust Target Pests

Ants, Crazy Ants, Cockroaches, Firebrats, Silverfish, Spiders, Mites, Bed Bugs, Lice, Fleas, Ticks, and Drywood Termites.


Ants, Cockroaches, Firebrats, Silverfish, Spiders, Mites, Bed Bugs, Lice, Fleas, Ticks, Drywood Termites. Kills Bed Bug Adults and Nymphs Kills Bed Bug Nymphs Hatched from Dusted Eggs kills Pyrethroid-Resistant Bed Bugs.

Target Uses

CimeXa Insecticide Dust can be used in place of other similar insecticide dusts and used in voids, cracks and crevices for most common crawling insect pests. Because of its stability, CimeXa Dust is ideal for tedious or time-consuming dusting treatments, such as treatments of wall voids or attic spaces. CimeXa Dust is also an excellent dust for bed bug treatments because there is no known resistance to it. CimeXa Dust is completely natural, making it preferable for use in sensitive accounts or locations.

CimeXa Insecticide Dust Application Instructions

Apply at a rate of 2 ounces per 100 square feet. Use a handheld bellows, bulb, or puffer bottle type duster to apply a light, visible film. A power duster may also be used. Power duster use is limited to cracks, crevices, voids, attics and crawlspaces to insure containment of dust particles. Focus on areas where insects or their signs are seen.

CimeXa Dust may also be used as a spray, paint-on application, or foam. Combine 1 lb of product per gal. of water. Apply approximately 1 qt. of solution per 250 square feet of area to be treated. For injection treatment, add the appropriate amount of foaming agent to the product/water slurry and inject directly into galleries and voids.

A 4 oz. bottle covers approximately 200 square feet. A 5 lb. pail covers approximately 4,000-5,000 square feet.

Standard Application Rates

  • 2 oz. per 100 square feet
  • 1 lb. per 1,000 square feet – attics and crawlspaces
  • Liquid application: Mix 1 lb. dust with 1 gallon of clean water. Apply 1 quart of solution per 250 square feet

For use in the following areas:

In and around residential, multi-family, commercial, industrial, institutional, municipal, agricultural, research, daycare, health care, educational, recreational, and office buildings, hotels, motels, garages, transport vehicles, warehouses, theaters, food handling and food processing establishments, Federally inspected meat and poultry plants.


In attics, be sure to get dust near the eaves and vent pipes where insects often first enter, as well as around any pipes or potential access points between the attic and the main structure.

The bottom drawers in kitchen and bathroom cabinets can be removed and dust applied into drawer wells. No dust should be left exposed when drawers are replaced.

Cimexa Bed Bug Treatment: Remove bedding and take the bed apart. Treat the interior framework, joints and cracks in the bed frame. Treat the mattress and box spring, paying particular attention to tufts, folds and edges, and the interior framework of the box spring. Remove wall-mounted headboards and treat the back side. Treat picture frames, moldings, hollow furniture legs, cracks and crevices, along baseboards, and any areas with visible signs of infestation, including rugs and carpet. Treat upholstered furniture by removing or lifting (if possible) the cushions and treating the undersurface. Treat the interior framework, cracks and joints of the furniture, and the folds, tufts and edges of cushions and other upholstered areas. Do not treat toys and stuffed animals with product. Treat wall voids by removing electrical switch plate covers to allow access, but don’t apply dust directly in electrical boxes. Apply about ¼ oz of dust to each accessible void.

Cimexa for Flea Control:  Apply at a rate of 2 ounces per 100 square feet. Treat kennels, pet bedding/rest areas, floor and floor coverings (such as carpets), cracks behind molding and baseboards and other areas where pests may harbor.  Apply as a light film or light coating over the target surfaces.

    5 of 5 stars  Hands down the BEST bed bug treatment product on the market
    By Ken in Billings, MT on 08/13/2015

    YEAH YEAH, We've all heard the accolades of Diatomaceous earth and how it's the best "go to" treatment for bed bugs. well, I've got news for you, this leaves DE in the dust. hehe. Ok, I will take you down the rabbit hole of our bedbug hell. I'm no idiot. I've tried things and used empirical evidence to support a conclusion. We got bed bugs when we got a free king sized mattress that had been left behind by a tenant of the apartment we moved into. Had I know the hell that would follow, I wouldn't have moved into the apartment. The bed was infested and little did I know, that meant the entire house was infested. When I was finally able to identify the "mosquito bites" or rash that had magically appeared, I did a lot of extensive research to properly fight the pest and eradicate it. Now, I'm one of those people that the bites affect badly, so I was suffering quite a lot. My first purchase was an encasement for the bed and box springs. absolutely mandatory. You have to isolate any bugs away from you. Second mandatory purchase are climb up interceptors for the legs of your bed and furniture. Once you isolate your bed, then you can begin treatment. I tried alcohol, bedlam sprays, pretty much every expensive spray under the sun that you can purchase as an individual without a license. sure, the sprays did kill the bugs, but the damn things hide in every conceivable crack and nook. Sure, you spray the cracks and nooks with the sprays and it'll kill for a short while. But Cimexa, now that's an entirely different story. DE takes a bit of time to kill the bugs. Cimexa isn't instantaneous, but it DOES kill them every time they touch it. Lay a thin layer of Cimexa around the perimeter of your room. lay a thin dusting around anything you suspect may have bugs hidden in them and let the stuff do it's work. Put some in your climb up interceptors and around your bedframe and inside your encasements. Literally create an impenetrable barrier around yourself and let the bugs come to you, through the dust to their death. We fought for 2 YEARS using traditional DE and other treatments to no effect, however after using Cimexa, we stopped seeing them. It's now been a year since we've seen a bug in our rooms (and I mean ANY bug) though we still keep the interceptors and cimexa in place. I have a spare bottle i keep around for emergencies and have even started using it to get rid of bugs in my garden and hydroponics. The evidence showed a slight decrease with every single product but ultimately didn't provide the final solution. Cimexa did. I am a firm believer that Cimexa ALONE if used correctly and over time, will completely rid you of your bed bug problem. The bugs will always come seeking food (you) and as long as your protected by a barrier of dust of cimexa, while they may get you here and there, they have sealed their fate by walking over the cimexa to get to you to feast and it will be the last thing they do. Just like laying landmines around a fortified base, as the enemy continues to send troops your way, eventually they will have no more troops to send and you will have won by attrition. Oh also, make sure to adequately dust the inside of your furniture as well. Literally any place you "hang" that will provide a food source they can reach, will harbor the bugs, so do yourself a favor and spray Cimexa inside the couch and such too. You will want a dust mask as it hangs in the air for quite a long time it's so light.

    Expert Response   Expert response:
    Thank you for the in depth review of Cimexa! While we agree that Cimexa is an excellent product we do not recommend you use it alone to control a bedbug infestation because it can take several days to actually kill the bedbugs and in that time they can reproduce. Please take time to read our Bedbug Guide which explains how to effectively implement a bedbug program:

    5 of 5 stars  Works great but read below
    By Nick in IL on 12/05/2013

    This is an impressive product that decimated a flea problem in our couch. I used it under the cushions and along edges. I also used it in low traffic problem areas on the carpet and pet bed. Be aware the dust is VERY fine and does hang in the air which is why I avoided using it on all of the carpet floors.

    5 of 5 stars  Love seeing those suckers shrivel up
    By Tammy in Yarmouth, Maine on 06/03/2016
    Verified Purchase

    Yes, I am in a battle with the bed bugs - it is a pleasure to see their shriveled little bodies lying on top of my mattress encasement after using this stuff. I could not see any of the little suckers when I inspected, but the bites grew more numerous so I went ahead and treated. Thanks to CymeXa I now can see the dried up little corpses of the vampires that have been feeding on me. I hope their death - though fast - was painful and torturous. I have a couple of dusters that I've tried, but actually find dusting right from the CimeXa bottle is easiest. I will use this stuff for the rest of my life.

    5 of 5 stars  CimeXa Insecticide Dust is an awesome product
    By Deb in Ottumwa, IA on 07/27/2014
    Verified Purchase

    I had cockroaches and others when I moved into my house that I rent. I followed the directions to a t. I used it around all my furniture including bookshelves, tv stands, couches, etc. I did this once a week and in about two weeks I noticed I was seeing less and less bugs all the time after a month I am not seeing any bugs at all. I still will apply the dust if I do starting seeing bugs again. I have also recommended CimeXa to my family and friends. It killed bugs and spiders that I did not even know I had. The bellow duster is also recommended as well, makes the application to the walls a lot easier and saves a lot of time.

  • 5 of 5 stars  Great Product
    By Beverly in Adamsville, TN on 12/02/2017

    I do appreciate all your information that your Customer Service supplied concerning help with getting rid of these pesky bed bugs. I had tried everything, mattress, pillow, box springs (even new ones) incasements, 2 trips from professional pest control. I've been washing in hot water, drying on highest heat. Then, I read about your CimeXa; used it as directed and slowly, but surely will be rid of these bugs soon. I continue to use sprays, heat, drying, and the Cimexa in other areas that I have not seen bugs. Thanks for a great product; I think it is the answer instead of repeated chemical spraying.

    By Paxton in Surprise on 11/24/2017

    5 of 5 stars  CIMEXA WORKS LIKE A MIRACLE!
    By Angela in Dallas, Texas on 08/11/2017

    For many months I have been living a nightmare, plagued with bedbugs that I just could not get rid of. I had professional exterminators, effective for anywhere from a few days to a week, they even came back to do follow up treatment. Knocked the bugs back a little, but did not kill them. I tried applying diatomaceous earth, with limited good results. Knocked them back, but had to reapply every day, or wake up covered with the tell-tale red welts. Heard about this CimeXa, ordered some, one application, no bugs...none! Thank you, thank you, thank you! I also want to mention that my order was delivered promptly as agreed, was in excellent shape and DoMyOwn is a great company to work with!

    5 of 5 stars  Peace of mind!!!
    By Elle in LAS VEGAS, NV on 06/29/2017

    I'm a newer home owner and I've been having a really rough start... My house flooded and the entire downstairs of my house had to be redone. I purchased all new furniture and a month later, family found out they had a serious bedbug infestation caused by a couch from an estate sale. My kids frequent their home and then I noticed I was getting bit. My water heater had blown during this time and money was tight so a professional was out of the question... I don't know how long it had been since they were carried into my home but I do know Cimexa handled them within a week. I had only saw them and been bit on my new couch... I had purchased phantom, gentrol, and cimexa but out of desperation, reached for the cimexa one night and went to town. ***A few hints*** Turn off any ceiling fans before dusting... and wear a face mask. I didn't and I paid dearly for it for about a day. Also use gloves. The dust will dry out anything it touches. I had pulled the staples out of the back of the couch and dusted inside, under the cushions, cracks, crevices, flipped the couch over and got the bottom and legs, and then did the baseboards and floor underneath. I saw one bug about 2 days after, mid day (probably dehydrated and disoriented), and charging at my husband. We killed it and haven't seen a single bug on the couch since. A week after the cimexa and no bites, I got around to treating the house with phantom and gentrol, 3 oz of phantom, 1 gallon of water, and a bottle of gentrol... I haven't received another bite (I was the only one showing signs of bites). Each room/bed/couch/loveseat has now been treated with cimexa for precaution. It's summertime in a dry, hot climate and not a single bug has been spotted in my home. I'm so thankful to!! I only wish I had found this for my parents before they shelled out 10k to have everything treated. I'll be setting up a spray schedule for my home and spraying their home, too, as well as dusting their furniture for prevention. Seriously, if you have bedbugs, use this product. It works!!

QI have bedbugs and I live in an aparment that has carpet. Do bedbug live in or under carpet?
Does carpet need treatment? What spay should be used on carpet?

ABedbugs will hide wherever there are places for them to hide. In most situations you will not be required to spray all of the carpet for bedbugs because bedbugs will not sit out in the middle of the carpet. Usually you will concentrate your treatments up under the lip of the carpet. A dust insecticide such as Cimexa Dust would be a great choice because it stays active for a every long time.

QAre there advantages to using CimeXa Insecticide Dust versus the Alpine dust?

AThere are two main advantages.  Cimexa is 100% Cilica, which is basically ground up sand.  It is 100% natural and green.  The other advantage is that in undisturbed areas CimeXa can last up to 10 years, whereas other dusts including Alpine will typically only last 1 or 2 years at the most.

QI have read to not have children around when applying Cimexa.
I have not seen it addressed that children will ultimately be on the carpet or touching items/toys that have cimexa on it, breathing it, transferring to face etc. can you address residual for children?

AChildren should not be allowed back in the area until the CimeXa Insecticide Dust has settled.  You are normally applying it to cracks and crevices and wall voids. CimeXa Insecticide Dust should not be applied to kids toys or carpet where they may be putting the item in there mouths.

AAlthough, Cimexa contains 100% natural silica gel, we still do not advice breathing it in. It could be harmful to you. You may want to consider wearing a Respirator mask when making your application.

QIs Cimexa suspended in water suppose to leave a white Residue?
I mixed one 4oz bottle of Cimexa with 1 quart of water, this should be 1/4th of the usual 1 lb to 1 Gallon of water formula. The solutions looks very cloudy and when applied leaves a white residue. I know I'm suppose to thinly apply dry dust or else the bed bugs will avoid walking in it. My question is, will the bed bugs avoid the white residue?


Per the CimeXa label,††the product does not dissolve in water and will be left behind after evaporation. †So you don't need to apply it very heavy, just a light dusting will be enough that the bed bugs will walk through it and pick the dust up on their bodies.
