The Asian ladybugs found in the USA were introduced in the country to try and control pesky aphids, particularly the ones that were chowing down on our soybean crops. In your garden, they eat aphids and other insects in your trees and shrubs. However, this species reproduces fast and becomes a nuisance in late fall and winter when they prepare to hibernate. Country areas, wooded industrial and residential areas are especially prone to having severe infestation problems.
So, in spite of their beneficial function in controlling aphids, we are seeing a lot of them because it’s finally starting to get cooler and large quantities of these beetles are looking for some warmth. When temperatures start to cool down, they will go looking for a place to hibernate. As such, they are attracted to light colored homes and heat that the homes reflect. Once ladybugs have intruded your home, they are hard to eliminate.
If they are already in, and there not many, just leave them. They will go away when spring arrives. Do not disturb them, as these little critters release a small amount of a yellowish fluid and produce a foul odor when they sense danger. But, if you still want to get them out of your house, you can use a “shop vacuum.” This type of device is easy to use to collect ladybugs. Make sure to use a clean bag or pad the bottom with a cloth. After they have been removed, release the beetles outside.
