Killmer from Austin, Tx writes,

Why should you not leave Demon mixed with water in proper storage? Will it retain stength?

I see the answer posted not to leave Demon mixed up with water if you have left over for example, I wold like to know why. safety? strength?


Demon WP should be used with 24 hours after it has been diluted with water. There are a couple of reasons for this 1. insecticides will start to degrade if they are left standing in water because of the acid in water 2. Demon WP never truly dissolves in water and it will separate and clog your sprayer. You should also note that leaving liquids standing in your sprayer will void the warranty of most sprayers as most chemicals and even water will corrode the tank, seals and other sprayer parts when sprayer is not properly rinsed between uses.
