Product Overview

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. It will work on ants, roaches, firebrats, silverfish, spiders, mites, lice, stored product/pantry/fabric/clothes beetles, moths and drywood termites. When pests come into contact with CimeXa, the product clings to their exoskeleton and absorbs the waxy coating, causing death from dehydration.

*CimeXa Insecticide Dust is packaged by product weight.  Each bottle is packaged with 4 oz of dust inside.  The bottle will not appear full but will contain the correct 4 oz dry weight.  The larger bottle allows for adequate airflow to expel a fine application of dust when applying.

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

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.

    Hands down the BEST bed bug treatment product on the market

    By Ken 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 ResponseExpert 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:

    Love seeing those suckers shrivel up

    By Tammy 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.

    Works great but read below

    By Nick 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.

    CimeXa Insecticide Dust is an awesome product

    By Deb 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.

    Bird Mite Battle - I won!!

    By Dominica on 11/25/2015

    Verified Purchase

    My mite issue started with birds nesting in my vents on the 2nd floor of my house. I always heard birds and actually thought they were in my attic, but they were nesting in the vents. Got the vents sealed like with wire mesh by a company in April or May 2015 and the nightmare started the following month. The company found a nest and a dead bird inside the vent and told me all was okay. Yeah right! Now fast forward a month or so. I noticed bites on my leg one morning, then also saw a mite crawling across my cell phone screen and across my body. Then I did like everybody did and bought the local Bed bug products from Home Depot/Lowes which didn't work. My dad later came to my house to check on my condition and to spray my house with more powerful chemicals he had. He also checked on my vents and saw that there was 2 more dead birds and a broken egg. He told me the company did a horrible job with sealing the vents with all the birds and garbage they let stay. So my dad cleaned out the vents, sprayed with the heavy duty chemicals and all of my house on the inside. He also added the wire mesh back on the vents as before. I didn't know the magnitude of work that was involved with getting rid of the mites. I bought the bedbug kit #3 from DMOPC, but only sprayed the inside my house, all rooms. I dusted with the bulb duster as well. I followed the directions as if I was trying to fight Bed Bugs (BB). However, what I didn't know was I needed to stay consistent with exterminating the mites weekly. I had only treated my house once or twice with the kit. I even switched to an organic cedar and fogged my house and attic. Worst mistake ever. The hydrated silica in the cedar messing up my stove and cooking pots. Plus there was no residual killing power in Cedar oil and it was a losing battle using Cedar oil. So I went back DMOPC. Next purchase was Gentrol and Onslaught. I'd mix the two and sprayed the attic, eaves, outside house, garage, and entire inside of house (even ceiling). I vacuumed almost daily. Spraying the ceiling was extreme but mites crawl everywhere. They don't just congregate to one spot like the bed as BB do. To prevent the mites from getting resistant to Onslaught, I also bought ExciteR, Bifen, Permethrin SFR 36.8%, and Temp SC Ultra. I would rotate an Insecticides with an IGR, such as Gentrol and sprayed weekly. I think what truly got rid of the mites was when I started using CimeXa. Towards the end of my battle, I begin to spray my house (all the rooms listed above), then while damp from the spray, I dusted lightly with CimeXa so it could stick to the damp area from the Insecticide. CimeXa is the only dust I researched that is effective while wet/damp and it's good for 10 years. I even sprayed my vents (in ceiling of all rooms) with D-Force HPX and dusted with CimeXa. My infestation of the mites was slightly moderate and per directions of most of the insecticides I bought, suggested to spray weekly for heavy infestations. What I found out was, you can't treat bird mite infestation in the house with one treatment or one product. I stopped vacuuming daily towards the end of my battle when I began to dust the cracks, corners, ceilings with CimeXa (over the dampen wall space from the insecticide) because I didn't want to vacuum up the very product I needed to stay in place to kill any mites crawling on the floor. Now, I'm back to my normal weekly cleaning once a week. Gone are the weekends of spraying everything every 4 days. I sprayed every 4 days because I read the life cycle of a mite is 5-7 days and I wanted to get ahead of the life cycle by spraying and vacuuming the mites up. The mites infested my house May 2015 and it's now Nov 2015 and the issue is resolved. Granted it took me until mid October to start with the weekly rotation of spraying, then in late October, I dusted CimeXa (one application) over the dampen sprayed areas. Throughout this entire time, I wore the Safety kit, gloves, and mask each time I sprayed. I turned on my ceiling fans and opened windows after dusting to help clear the light cloud of dust. I would also state because of attrition, the mites are gone as well. They keep dying, but no more are coming back with the combination of the IGR and dust.

I 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?

Bedbugs 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.

Are there advantages to using CimeXa Insecticide Dust versus the Alpine dust?
There 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.

Can breathing in Cimexa hurt you
Although, 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.

I 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?

Children 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.
