"Omg this is the worst information I've seen to date on r.I.u."
Rory, I spent 15 years at UCLA as an animal tech. in the research labs. Sevin dust is so benign that it was vet-approved for direct bedding of rodents. Means the product is so tame that it was approved for direct use on research mice. Certain transgenic mice are valued at close to six figures because of all the labor they represent and nothing got OK'd for them unless we were positive of it's possible dangers. I have used it for 10 years on pot plants with nary a problem. I admit it is a good idea to use a spray bottle to wetten the leaves of any plant treated with an insecticide.
