This is a really good article and is worth reading all of it.
"Bt-based products tend to have a shorter shelf life than other
insecticides. Manufacturers generally indicate reduced effectiveness
after two to three years of storage. Liquid formulations are more
perishable than dry formulations. Shelf life is greatest when storage
conditions are cool, dry and out of direct sunlight."

I bought BT early this year and would like to use it now. Does anyone
know the shelf life on this stuff? I could call the mfgr. but would
like to apply it today when I have a chance.
Thanks in advance.
