Ladybugs are not only cute little beetles, they and their larvae very effectively control many damaging insects in the garden. There are many naturally occurring ladybugs, and you can also increase their numbers by releasing additional ladybugs into your landscape.
Before releasing ladybugs spray the foliage of insect-infested plants with water, then release the ladybugs at the base of the moistened plants. While not all of the ladybugs will remain on the infested plants, those that do will consume insects and will produce sufficient larvae for continued control. Those that fly away will seek out additional insect populations on which to feed. If the insect infestation is severe, control may take several weeks. Releasing ladybugs into the landscape every 6 to 8 weeks can help reduce future infestions.
