I read one of your Q&A that the insecticide should be used w/i 24 hours of mixing. I put a packet in a gallon container, mix & then fill a smaller sprayer and spray my apt as needed. It's been sitting around for over a day. Will it still be effective? Thank you
Using Diluted Demon Wp after it has been mixed 24 hours would not be advised. The reason being is that the active ingredient will start to break down and cause the solution to become less effective.
