New construction is a great time to apply various preventative pest control treatments to a home or building while the walls are exposed. CimeXa Insecticide Dust, a long-lasting dust that controls a variety of insects including ants, bed bugs, roaches, silverfish, and spiders, is one preventative pest control treatment that can be applied during new construction. 

CimeXa is typically applied post-construction as a dry dust into cracks, crevices, and voids around the home. But when mixed with water, it can be applied more easily by being sprayed directly onto the exposed exterior walls and interior studs of a building during construction. The water mixture will help the dust stick to the wall for a more efficient barrier. 

To create a liquid application of CimeXa, slowly add CimeXa dust to a gallon of water in a clean bucket using a scoop or plastic cup that will not be used for drinking. After each scoop, use a drill with a mixer attachment to thoroughly mix the dust and water together. Continue adding scoops of CimeXa to the water until the mixture is not thin and runny but is not so thick that it will not flow through your sprayer. You can add up to 1 pound of CimeXa dust to 1 gallon of water. 

Pour the mixture into your sprayer and replace the cap. 

The mixture can then be sprayed on the inside of walls that form the exterior of a home or building but not on the actual exterior of the building itself. Spray an even coat of the dust and water solution onto the exposed exterior walls of attics, crawlspaces, and new construction. Spray enough so that the wall is wet but not so much that the solution is dripping or running down the wall. Do not spray on walls finished with drywall or plaster.  

If you would prefer, you can make a thicker mix and paint the mixture on the walls with brushes and rollers. You can apply up to 1 quart of slurry per 250 square feet. 

After you have finished spraying the walls, thoroughly clean your sprayer by triple rinsing with water before any other use. Do not leave the solution in the sprayer as it will turn into a thick gel that will be extremely difficult to remove.  

Allow the walls to dry before applying insulation or drywall. 

Once dry, the insecticide dust will create a long-lasting kill to insects that manage to crawl into the home. The dust can last up to 10 years when it is undisturbed.
