Hello there, I will sometimes release lady bugs on the property. Some stay, some don't. (actually, most don't). Anyways, IMO the best way to control the aphids and stuff it by using neem oil. Buy the concentrate and mix it with water in one of those sprayers. (I have a sprayer that is dedicated to ONLY garden use) I don't want whatever strange things my dad uses in it anywhere near my garden no matter how many times it has been rinsed out. Anyways, that neem oil is good for a lot of things, generally I have to use it for powdery mildew and it takes care of a lot of pests in the process. it doesn't take but a few minutes to treat the entire garden every couple of days. It kind of reminds me of Raleigh salve for plants. Anybody else know what i'm talking about? gramma always used to keep a can beside her bed and would say "cut, burn, rash, infection, pimple, cyst, whatever be your ailment, Raleigh will fix it right up. Just make sure you use a clean finger to dip in the tin". Anyways, i'm probably talking to myself and nobody cares/knows what i'm talking about.
Basically, my recommendation is neem oil. Good luck!
