Product Overview

CSI Optimate CS is a microencapsulated insecticide for use on and around buildings and structures. CSI Optimate CS is for the control of listed pests, including on lawns, ornamental trees and shrubs, around residential, institutional, public, commercial, agricultural and industrial buildings; parks, recreational areas and athletic elds; and livestock/poultry housing and pet kennels.

New to the professional pest control market, and exclusive to CSI Optimate CS, Gamma-Cyhalothrin is a single biologically active isomer which allows for the same strength at half the use rate of Lambda-Cyhalothrin products.

For Poultry Housing: 1 pint of CSI Optimate CS treats up to 24,000 square feet when treating for litter beetles. Can be used on entire footing, crack and crevice, or banded applications. Effective against adults and immature Darkling beetles, Hide and Carrion beetles.

Directions for Use:

All outdoor applications must be limited to spot or crack-and-crevice treatments only, except for the following permitted uses:

  1. Treatment to soil or vegetation around structures;
  2. Applications to lawns, turf, and other vegetation;
  3. Applications to building foundations, up to a maximum height of 3 feet.

Other than applications to building foundations, all outdoor applications to impervious surfaces such as sidewalks, driveways, patios, porches, and structural surfaces (such as windows, doors, and eaves) are limited to spot and crack-and-crevice applications only.

Outdoor Surfaces and Perimeters

To control flies, fleas, mosquitoes, ants, bees, wasps, centipedes, cockroaches, crickets, pillbugs, scorpions, sowbugs, spiders, termites* (above ground only), ticks and other listed pests, apply OptiMate CS with either hand or power application equipment as a residual treatment to ornamental plants next to foundations of buildings and to external surfaces of buildings, porches, screens, door and window frames, eaves, patios, garages, refuse dumps and other areas where insects rest or congregate. OptiMate CS may also be applied to lawns around non-residential buildings, or to refuse dumps or other non-residential areas where these insect pests congregate. Remove all exposed food and cooking utensils and cover all food handling surfaces or wash thoroughly after treatment and before use.                         Do Not Use on Edible Crops.

For Perimeter treatments, apply a continual band of insecticide around building foundations and around windows, doors, service line entrances, eaves, vents, and other areas to reduce the potential for entry by crawling pests. Before application, remove debris and leaf litter from next to the foundation, cut back vegetation and branches that touch the foundation, and move or rake back rocks, deep mulch, or other potential pest harborage next to the foundation. apply the band up to 10 ft. wide around the structure (or according to state regulations governing commercial pest control) and upwards along the foundation to 3 ft. and around windows, doors, and roof overhangs. apply as a coarse spray to thoroughly and uniformly wet the foundation and/or band area so that the insecticide will reach the soil or thatch level where pests may be active

    Definitely does the job

    By Spenser on 11/12/2021

    I work in the Pest Control industry and have experimented with many different products to control a variety of different pest issues. This product will definitely provide a effective protection barrier for most insect issues around a home and even begins working fairly quickly in eliminating pests. For example: used this on a home and a single wasp just happened to be in the path of the treatment and within one minute was already laying upside down on the ground dying. Definitely worth the money and will purchase again.

will this product control bird mites in a chicken coupe?

the mites are not the red mite that attack chickens. They possibly came from blue jays or ravens. Thanks

Optimate CS is not actually labeled for bird mites though it is labeled for many other kinds of mites. We recommend that you contact the manufacturer directly to see if they would recommend their product for bird mite control. You can reach Control Solutions by calling 1-281-892-2500.

How does Optimate CS compare to Cyzmic CS as a general pest control treatment around the home?
Optimate CS and Cyzmic CS are both microencapsulated insecticides for use on and around buildings and structures. Optimate CS contains Gamma-cyhalothrin and Cyzmic CS contains
Lamda Cyhalothrin as its active ingredient. Both are great general pest control products and made by the same manufacturer.

Is Optimate CS product supposed to be yellow in color? The bottles I received have dull yellow-colored chemical and it is quite watery. I am concerned this was from a batch manufactured years ago and is no longer stable.

The SDS states that the Optimate CS should be a Beige liquid. We get the freshest batches available from our suppliers/manufacturers. This product has a 3-5 year shelf life when stored properly. If you do not see a date on the bottle (the manufacture date), we can further look into this further for you with the manufacturer if you are able to provide the lot number of the bottle(s).
