Attracting Ladybugs in the Garden
Apart from aphids, ladybugs also require a source of pollen for food and are attracted to specific types of plants. The most popular ones have umbrella shaped flowers such as fennel, dill, cilantro, caraway, angelica, tansy, wild carrot & yarrow. Other plants that also attract ladybugs include cosmos (especially the white ones), coreopsis, and scented geraniums, dandelions.

Apart from planting attractive plants in the garden, you can also promote ladybug populations by cutting bag on spraying insecticides. Not only are ladybugs sensitive to most synthetic insecticides, but if the majority of their food source is gone, they won't lay their eggs in your garden. As difficult as it may be, allowing aphids to live on certain plants is necessary to ensure that there is enough food for ladybugs. In addition, resist the urge to squish bugs & eggs in the garden, unless you're certain that they are not beneficial.
