Suspend Polyzone is labeled for controlling aphids and other pests on plants and in flower gardens, but it does not specifically list mealybugs on the label so we cannot say for certain it will control them. However the Suspend SC which is just the non-polymer version of Suspend Polyzone does list both aphids, mealybugs and hundreds of other similar pests on the label.
Suspend Polyzone is a great professional-grade pesticide that will treat all of the pests you mentioned (as well as many others) and will hold up well in your Florida weather conditions.Suspend Polyzone features a proprietary polymer layer that protects the active ingredient from weather, irrigation and mechanical abrasion. It can last up to 90 days outdoors. This product can also be used indoors as well around the baseboards and cracks and crevices.
The biggest difference between Demand CS and Suspend Polyzone is the residual they have outdoors. Suspend Polyzone was designed with special time release polymer coating to hold up in heat, cold, and irrigation for up to 90 days. Demand CS will last approx 30 days.
Suspend Polyzone is formulated to last longer than other pesticides in heat, sunlight, and other extreme weather. There is not a specific temperature requirement or limit for applying it outdoors, as long as temperatures are over freezing. We recommend spraying in the morning or evening when temperatures are cooler for your own comfort and since pollinators are less active during those times. You can retreat at 30, 60, or 90 days intervals depending on pest pressure and rainfall.
Any edibles that have been sprayed with Suspend Polyzone are not fit for consumption and should be discarded. Also, the area that was treated can not be used for at least one growing season. If you wish to reuse the area right away, the soil must be replaced.
