Eric from Boston, Ma writes

Can I use the mixed solution of Demize Nylar IGR several days later?

The directions for mixing and using this stuff say not to let it stand overnight. What happens if I do? Does it become ineffective? Can I use a batch that I mixed up several days or a week later, if I shake it up good?


The longer some concentrated liquids stay in a diluted form the faster they degrade, making them ineffective. Shaking the solution will not help the degraded products work any better. We recommend only mixing up what you can use at one time. Also, storing solutions in your sprayer will cause the seals and gaskets and other pieces in your sprayer to break down.
