Optimate CS Insecticide, manufactured by Control Solutions, is a microencapsulated insecticide that contains the active ingredient Gamma-Cyhalothrin, a powerful insect-killing chemical.

Optimate CS has a controlled-release formula that allows the product to continue killing for up to three months after application.

Tools Needed

To use Optimate CS, you will need a hose-end sprayer, handheld pump sprayer, backpack sprayer, or spray rig. For small household jobs, we recommend a handheld 1-gallon pump sprayer or a 4-gallon backpack sprayer.

How to Use

  • Step 1: Determine how much Optimate CS Insecticide to use by measuring the square footage of the treatment area. You can do this by measuring the length and width of the treatment area in feet, then multiply them together (length x width = square footage). Optimate CS can be applied at different dilution ratios depending on the pest being treated. 0.0075% concentration would be 0.16 fl. oz. in a gallon of water or 0.5 fl. oz. in 3 gallons of water. A 0.015% concentration would be 0.33 fl. oz. in 1 gallon of water or 1 to 2 fl. oz. in 3 gallons of water. A 0.03% concentration is 0.65 fl. oz. in 1 gallon of water or 2.0 fl. oz. in 3 gallons of water. All of these rates would treat 1,000 sq. ft. So, for example, if you have 3,000 sq. ft. to treat and want to use the 0.0065% ratio, you would need to mix 0.5 fl. oz. in 3 gallons of water.
  • Step 2: Fill your sprayer halfway with the required amount of water. Based on your calculations, add the appropriate measured amount of Optimate CS. Fill the sprayer with the remaining amount of water and agitate it. Once well mixed, you are ready to spray.
  • Step 3: Apply the Optimate CS insecticide as a perimeter barrier treatment around your home and spray in cracks and crevices.
  • Step 4: Reapply Optimate CS every 21 days as needed for continuous control of your target pest.

Where to Use

Spraying Optimate CS under a fridge

Optimate CS can be used indoors and outdoors to control a wide range of pests. Focus your treatments around foundations of buildings, surface cracks, windows, doors, eaves, patios, garages, trash and dumpster areas, and other harborage and entry points. For perimeter pest control, spray Optimate CS Insecticide 3 feet up the foundation and 10 feet away from the foundation.

When to Use

You should use Optimate CS when pest activity is high. For most areas of the country, this is between the spring and summer months. Apply the product quarterly for year-round control.

Safety Information

Optimate CS is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product. 

Keep children and pets off-treated areas until the spray has dried following application.

Special Considerations

Because Optimate CS is a microencapsulated insecticide formulation, it will need to be constantly agitated in the sprayer during application for best results.
