Dr Earth products containing rosemary,sesame and thyme oil are appearing on the shelves in place of the Safer products. I know that these herbs do have repellent properties but has anyone tried these products? How well do they work?

They sound good and according to the label does have some residual. Like most oils it cannot be used in the heat of the day but it lists beetles, leaf hoppers, and crickets which the potassium salts and neem usually cannot kill because of the hard bodies.
The only things I found were positive. The only caveats have been that because they are oils they are hard to use when the temperature is over 80 degrees because the plants could burn. Unfortunately it is over 80 degrees for most of the year here. It is one of the many reasons I don't use a lot of neem or horticultural oils.
