Todd from Spencer, Wi writes,
Can I leave diluted spray in my sprayer overnight? Can I use it next day? If not why?
Insecticide manufacturers do not recommend that you leave the products in the diluted states for more than 24 hours or you will risk the efficacy. The longer the products sit in the diluted state the more they will lose their potency. You can also risk breaking down the components on your hand pump sprayer.
