I judge the safety of pest control measures by the toxicity of the product and how it is used, rather than if it "seems" safe. We (my wife) have raised and sold tomatoes and other vegetables at farmers markets for over 20 years, so we go by the science. We do not treat for Asian lady beetles because they are really just a nuisance to us, rather than actually causing any harm. They also act as beneficials by eating pest insects.
