When I make a batch of the insecticide in a sprayer with water, is it still effective for use days later?
As Phantom (and most other insecticides) sit in the diluted solution they will start to breakdown causing them to be less effective or not effective at all. We recommend using the solution within 24 hours of mixing. Leftover solution can be poured out directly next to your foundation. The sprayer should be thoroughly rinsed after each use to prevent the seals and gaskets from breaking down.
