These products are effective and are a great formulation to consider for your pest control program. Soluble powders are a specialized formulation of insecticide where the active ingredient comes in powder form (much like wettable powders) but is able to blend into a complete solution which can the used and sprayed onto surfaces and into cracks crevices and voids to control various problematic pests.

On this page we will touch on the benefits of soluble powders, how they are formulated, and how to properly apply these products to achieve the best possible results. You can also shop the soluble powder and water soluble pack brands we have here at Solutions Pest & Lawn.

What is a water soluble powder?

Soluble powder formulations (also known as water soluble powders or water soluble packets) look similar to wettable powders. However, the main difference is that when mixed with water, soluble powders dissolve readily and form a true solution much like when sugar dissolves into water. A true solution is when one chemical is fully dissolved into another and the resulting liquid is clear (particles of added material completely disassociate into individual molecules). Particles in solution cannot be seen, or separated by physical or mechanical methods. 

Once soluble powders are initially agitated and thoroughly mixed, there’s no need for further shaking to agitate the chemicals. The amount of active ingredient in soluble powders ranges from 15% to 95% by weight; it usually is more than 50%. The percentage of active ingredient in a soluble powder is high compared to Emulsifiable Concentrates and Wettable Powders.

Soluble powders have all the advantages of wettable powders and none of the disadvantages except the inhalation hazard during mixing. Few pesticides are available in this formulation because few active ingredients are readily soluble in water.

Ideal Conditions To Use Water Soluble Powders

Water soluble powders are great to use for general pest control sprayings indoors and around your yard. Depending on the active ingredient, it can be used to treat a variety of pests and in herbicide form it can eliminate invasive weeds.


Water soluble powders are used to treat pests in agricultural, ornamental and turf, forestry, structural, (residential and commercial) ,food processing, livestock and public health settings. They are also adaptable to many types of application equipment--from small, portable sprayers to hydraulic sprayers, low-volume ground sprayers, mist blowers and low-volume aircraft sprayers.


Soluble powders often come in water soluble packets which make it convenient because the right dosage is in the packet and there’s no need to measure the powder to make sure you get the right amount.


Because the particle size of water soluble powders is larger than SC and EC formulations they work very well on porous surfaces such as brick, concrete, and raw wood. The larger particle size sits on the surface and is not absorbed into the material.


Benefits of Using Soluble Powders

Soluble powders contain much of the benefits of wettable powders.

Soluble powders and water soluble packets are simple to manufacture, transport and store. They are not abrasive nor will they clog up screens and nozzles. Unlike wettable powders, soluble powders leave no visible residue on treated surfaces and require little agitation because they will not settle out or separate when equipment is being used.


Soluble powders are easy to use--simply mix a small amount of the powder or use a pre-measured water soluble packet with water according to the label instructions and you’re set. SP’s usually dry quickly and clear and give a great residual effect which may last between 28 to 90 days.  Typically because of their high concentrations of active ingredient soluble powder products are cheaper to use for treatments which require a large amount of spraying.


Drawbacks of Using Water Soluble Powders

There is a very limited availability and variety of soluble powder products because not very many product active ingredients out there can dissolve into water to form a true solution.
