Ladybugs vs. Spider Mites

[Leafmite]

Every spring, I order lady bugs and lacewing eggs after putting my plants outside. Usually, in autumn, a few lady bug larvae/eggs come in with the plants and provide control (I grow on shelves i a sliding glass doorway). This fall, I found lacewing larvae on some of my plants but I hope there will also be some lady bug larvae, too. The lady bugs will stay close to the plants and will continue the cycle through the winter, providing me with control but I am not sure what the lacewings will do....
