(Once opened, & mixed with the water, does it need to be used up in one dose)
Monterey B.T.Ready-to-Spray Insecticide comes Ready To Spray and so there would be no need apply with another sprayer or mix with water. The nozzle on the spray is calibrated to the right application ratio, just hook it up to your hose and you are ready to spray. If you purchased the concentrate and are mixing it yourself, you need to use what you mix within 24 hours, and store the unused portion in a temperature-stable environment.
