I’ll probably be getting Cypermethrin, the water soluble kind, and also Maxforce Granules. I’ve used those before. In the past I’ve gotten more than I needed and used it for subsequent years. I always presumed some loss of effectiveness with older product (after the first year).
Would you know what the loss of potency is on these products? Do they maintain there strength or weaken off to nothing?
For the most part, there is no real change or degradation for several years. If stored in a cool, dry environment away from direct sunlight, most everything we sell will remain stable for many years. When “bulk size” buying, limit your sizes to what you’ll use in three years. Everything we sell should last 3-5 years without changes when stored right; keeping in the 3 year limit means you should always be Ok with what you have in stock.
