The ladybug has always been popular. These pretty little insects are considered a symbol of good luck and good fortune. Did you know their also popular because of their ability to eat an enormous amount of aphids? One ladybug can eat as many as 50 to 60 aphids per day. Aphids (also called plant lice) are herbivores and are one of the worst groups of pests on plants. They feed in colonies and damage plants by sucking the juice out of the leaves, stems, or roots. Aphids also transmit many plant diseases from one plant to another. Apart from aphids, ladybugs eat a variety of other insects and larvae including white flies, mealy bugs, spider mites, and other types of soft-bodied insects.
Ladybugs require a source of pollen for food and for that reason are attracted to certain types of plants. Their favorite plants dill, fennel, angelica, tansy, caraway, cilantro, yarrow, and wild carrot. Other plants that attract ladybugs include cosmos (especially the white ones), dandelions, coreopsis, and scented geraniums.
To further promote ladybug populations, consider cutting back on spraying insecticides in your garden. Ladybugs are sensitive to most synthetic insecticides and if the majority of their food source is gone, they will not lay their eggs and therefore will not continue to populate.

Create an alluring environment for ladybugs and they are sure to provide charm and pest control in your garden for years to come.
