The only pesticide I use is organic. In mid-May, I'll put out 4,500 ladybugs. Of course, since I don['t want them tto fly away, I clip their wings and name every one of the little bugs. Since they do eventually fly away home, I replenish the supply every month...just as you would with a non-organic pesticide. If you just follow the directions on the package, the ladybugs can do a lot of good in a garden.
