When applied at a preventative dilution, Crop Control will not kill mantis or lady bugs.
If there is a food source for beneficials to eat, they tend to stay with your plants.
However, if you have a clean plant and you’re using Crop Control as an IPM, it may deter them from coming on. Crop Control will kill most predatory mites but will not kill insects.
If beneficials are present, you most likely won’t have a pest problem. If you have a pest problem and use Crop Control, the beneficials have no reason to come around.
