Ladybugs and the Asian lady beetle are not synonymous, but they are often mistaken for the other. The Asian lady beetle, not the lady bug, is to blame for infiltrating homes. The U.S. government throughout the 20th century to reduce infestations of tree-killing aphids imported the Asian lady beetle. Both the lady bug and the Asian lady beetle eat aphids, keeping your garden healthy. Some gardeners order lady bugs and the Asian lady beetles to release in their garden to keep pests out.

Diatomaceous earth kills earwigs as well. Diatomaceous earth is a natural pesticide, safe for the environment and multi-functional for ridding your home of other unwanted insects.
Long-lasting pesticides help deter lady bug and Asian lady beetle migration. Long-lasting pesticides like pyrethrin and pyrethroid stay on exterior walls, in eaves, on windows, overhangs and in attic vents for a whole season without reapplication. These insecticides are found in local hardware stores and in garden centers. The pyrethroids insecticide acts as an adhesive for pyrethrin when sprayed onto a surface. When lady bugs and Asian lady beetles come in contact with the poison they soon die.
