If Demand CS is leaving a visible residue, then we would recommend to use a lower dilution rate (0.2-0.4 oz. per gallon of water). Also, be sure you are only spraying as a spot and/or crack and crevice treatment. You could also consider going to an insecticide that is not micro-encapsulated, such as Talstar P. If you are removing all the reside, then you would need to reapply the insecticide.
Yes, Demand CS can be used for ladybugs.
Lawn Mix Rates: 3.4 - 7ml (0.1 to 0.2 fl oz) per 1,000 square feet / 5-10 fl per acre
Ornamental Rates: 0.4 - 1.3ml (1.5 to 5fl oz) used in 25 gallons of water.
For spot treatments, use 0.5 fl oz Demand CS Insecticide per 1–2 1/2 gal of water.
Since water is acting as the carrier, each treatment and the amount of water that will be used is specific to the individual treatment. Please take a moment to review our How to use the Chapin Wet or Dry Hose End Sprayer Video for tips on how to set the dial for this sprayer.
Demand CS can be wiped up with hot water and soap. The product is safe for your dog even if over sprayed on the floor after it has completely dried.
Generally speaking, all insecticides need to be kept at room temperature area to prolong shelf life. You don't want to expose any insecticide to direct sunlight, high heat or freezing temperatures, as this could break the product down, and it will lose effectiveness. If your bottle of Demand CS was left outside for a week, there is a good chance it could be ok, depending on what the temperatures were that week. If the product isn't seperated at all or clumpy and mixes well with water, then it should still be fine to use, but it may not have the residual that it had before these conditions.
