Q.Can I Use Kaolin Clay Powder With The Liquid Soap & Water For The Insecticide For Stink Bugs Or Do I Have To Use Wp Surround?

I read this on your blog: The following information will help with mixing Kaolin clay for plants (or follow manufacturer’s instructions): Mix 1 quart (1 L.) of Kaolin clay (Surround) and 1 tablespoon (15 ml.) liquid soap with 2 gallons (7.5 L.) of water. Reapply Kaolin clay for plants every 7 to 21 days for at least four weeks. Kaolin clay insect control should occur within three applications as long as sufficient and uniform spray has been achieved. A nontoxic material, application of Kaolin clay in the garden does not seem to impact honeybee activity or other beneficial insects integral to healthy fruit trees or other food plants.

My understanding is that the Surround WP is a brand name for a kaolin clay product registered for agricultural use. If you purchase just the clay you could still use it as directed below with 3 cups of clay to a gallon of water, or the 4 cups (1 qt) with 2 gallons of water as suggested in our article. The addition of the liquid soap as a surfactant is optional.
