CimeXa Insecticide Dust: Different Application Methods for Bed Bug and Crawling Insect Treatments

CimeXa different application methods

CimeXa is an engineered silica dust that provides both rapid kill/control and long-lasting residual control, up to 10 years when undisturbed. The amorphous silica dust (amorphous means no crystalline content) is extremely light and non-repellent, which allows it to easily adhere and accumulate on the bodies of crawling insects as they move across it. Amorphous silica is a strong desiccant. It destroys the waxy cuticle of insects by removing the moisture in their bodies resulting in rapid dehydration and death.

Some Key Advantages of CimeXa

  • Odorless
  • Non-clumping
  • Non-staining
  • Low toxicity
  • Effective on bed bug strains resistant to pyrethroids and neonicotinoids

Recommended Application Equipment

Because the CimeXa is light, it has its advantages (and some challenges that are easy to overcome) when doing treatment applications. It is important to remember that only a light film is needed when applying CimeXa. Be careful not to over-apply. Check out the following recommended application equipment for various treatments using CimeXa, as well as a few tips and tricks.

Area of Application:  Wall voids, voids under and behind cabinets, sinks and tubs, in drawer wells, plumbing chases, weep holes, behind electrical outlets and baseboards, and in cracks & crevices where insects may harbor.

Suggested Equipment: Hand duster (bellows, bulb or puffer) or a low-volume electric duster.

Application Tips: Focus applications in areas where insects or their signs are seen. The lightweight CimeXa dust will float in void areas to provide better dust distribution and a more thorough overall treatment. You can also apply CimeXa as a foam using a foaming agent, and inject directly into galleries and voids.

Area of Application: Attic.

Suggested Equipment: Low-volume electric duster or power duster.

Application Tips: Be sure to get dust coverage 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.

Area of Application: Crawl Spaces.

Suggested Equipment: Low-volume electric duster or power duster.

Application Tips: Be sure to apply dust near/around potential entry points into the crawl space and into the main structure.

Area of Application: Mattresses, box springs, bed frames, and upholstered furniture.

Suggested Equipment: Paint brush, CimeXa bottle applicator, or handheld duster.

Application Tips: Work CimeXa into the desired locations with a brush (i.e. edges, tufts, creases and folds, and cracks/crevices). If the dust cover at the bottom of the box springs and upholstered furniture is not torn, use a handheld or electric duster. If the dust covers are no longer intact, CimeXa may be applied as a wettable dust using spray, paint, or foam applications on mattresses, box springs, metal bed frames, under box springs, and upholstered furniture. It is important to apply two light coats of the wettable dust and let the first coat dry before applying the second coat. The second light coat allows the CimeXa dust to sit up on the treated surface ensuring maximum pick up by the crawling insect.

Area of Application: Wall coverings (i.e. curtains, curtain rods, drapes, blinds)

Suggested Equipment: Paint Brush.

Application Tips: Use a paint brush and apply CimeXa into folds, hems and tufts. Lightly dust blind tracks. Also dust hollow curtain rods and curtain hardware.

Area of Application: For unfinished wood or fiber board.

Suggested Equipment: Paint brush or spray bottle (as wettable dust).

Application Tips: These surfaces are generally located on the rear, bottom, and interior of furniture. Apply CimeXa with a brush or spray on as a wettable powder for precise applications into harborage areas.

Area of Application: Carpets and rugs.

Suggested Equipment: Hand duster or spray bottle (as wettable dust).

Application Tips: Apply CimeXa using a hand duster or the CimeXa bottle applicator, and lightly work into the carpet with a brush or broom. Focus applications in infested areas and areas adjacent to infested areas.

    Where does one get a bulb or puffer if not in the extermination trade – without having to order it over the internet; Or could I simply use a paintbrush for all application?

    • You can use the 4 oz puffer bottle that CimeXa comes in. It will work similar to a bulb/puffer duster. Doing that along with using a paintbrush is all you need when applying CimeXa properly. Just remember not to overapply the dust. CimeXa is a very light dust, which is why the paintbrush methods works well (to reduce airborne particles). But a little goes a long way. A 4 oz bottle of CimeXa should last a long time!
