Pest Control liquids have come a long way over the years. We are going to cover EC, SC, CS & WP designators that we see on the pest control labels and what they mean. The two oldest being EC & WP with the newer CS & SC formulations gaining popularity in the pest control field.
EC or emulsified concentrate, simply put, is a liquid mixed with water to create a finish solution. They don’t have all the bells and whistles of the newer CS and SC formulations but are still very effective and generally a little cheaper than their newer cousins. The pros are that they are cheaper to use for jobs that require a large quantity like a termite pre-treat and they don’t stain as easily as a Wettable Powder (WP). The cons are they have a tendency to be absorbed by a porous surface and they don’t seem to have as long of residual as SC, CS and WP. Some examples of EC concentrates are Demon EC, Cynoff EC, Permethrin Pro, Prelude.
WP, or wettable powder, is simply that it is a powder that gets mixed in liquid and is applied through a sprayer. The pros of a WP are fast knock down of insect population and long residual life of the product. The cons are it leaves behind a white film on the surface that has been sprayed. Some examples of wettable powders are Cynoff WP, Tempo WP, Demon WP.
SC and CS formulations are what they call micro encapsulated suspended concentrates. They provide active ingredient in what’s basically a small bubble that suspends itself on the surface for the target pest to pick up as it crawls over it. The pros of SC and CS are long residual, low odor and non staining. The biggest con to these guys is their more expensive to use than the others. Some examples of SC and CS formulations are Cy Kick CS, Demand CS, Temprid SC, Cyzmic CS, and Termidor SC.
All of the product types mentioned above have their niche and when used together can provide you with a barrier around your home that will help keep your family safe.
