Calculating Pesticide Coverage
When applying a pesticide outdoors, the product label will usually project its contained volume to cover a number of square feet or square yards for a specific target area which will be a rectangular area.
Converting Area To Square Feet or Square Yards
A pesticide barrier around a home will generally extend about 3 feet from the foundation around the home's entire perimeter. For an example, assuming the total perimeter is 210 feet, the total square feet of the area would be 630 feet (210' x 3' = 630 sq/ft. There are 9 square feet to 1 square yard. Therefore 630 square feet would equal 70 square yards (630 divided by 9).
As another example. If you are spraying your garden which is 9 feet by 27 feet, the area would be 243 square feet (9' x 27' = 243) or 27 square yards (243' divided by 9').
Buy Only The Amount of Pesticide Needed
Purchase the least toxic pesticide that will sufficiently control the targeted pests. Follow the distribution instructions on the product label. Spraying or distributing more than recommended will not necessarily make it more effective. Storing any unused pesticide or insecticide can be a safety concern, therefore buy only the amount needed if possible.
