In North America ladybugs begin to appear indoors in the fall. They are looking to shelter from the cooler temperatures and find a protected area away from the winter elements.
Ladybugs have three main defenses against predators. Their brightly colored bodies warn potential predators that it is poisonous, even though these beetles are not. Ladybugs also secrete a bad tasting fluid when attacked which makes them an unwanted prey. Last, these beetles can play dead! When faced with a threatening situation, ladybugs pretend they are dead until the danger is gone.
They normally live in shrubs, trees, fields, gardens, and other plants that attract aphids. These beetles relocate once they eat all the aphids on one plant.
Ladybugs hibernate in the winter, therefore, finding a protected and warm environment in the late fall is imperative. This is when you will commonly see them around or inside your home or structure.
