Ladybugs are Everywhere!
Hippodamia convergent ladybugs congregate together in the fall to hibernate. These ladybugs can be found most often in the upper elevations of the Sierra Nevadas, Rocky, Appalachian, Blue Ridge Mountains and other mountainous areas throughout the United States and Canada.
This ladybug prefers to over winter around rock out croppings, under forest debris, in tall grassy areas and under tree bark.
‘Tis The Season! Ladybugs Are Looking For A Place To Hibernate. They are attracted to light colored homes, usually older homes and they are attracted to heat that the homes reflect. Once ladybugs have penetrated the home though, they are hard to get rid of.
Ladybugs release pheromones, it is sort of like “perfume” to attract other ladybugs. They use pheromones as a means of communication during mating and hibernation. Insect pheromones are very powerful. They can be detected by others up to a 1/4 mile away. This helps ladybugs find each other and it lets future generations know of a good place to “camp out” for the winter. The pheromones don’t go away easily. The chemical “scent” can remain year after year, and not only on the outside of a structure, but also within the walls, where ladybugs tend to hide before emerging into your home. So, scrubbing pheromones off a house is a BIG task, if not impossible.
The yellow stuff you might see from time to time is their blood (hemolymph). It, too, contains pheromones and it stains. You can see the yellow blood when you hold a ladybug and it gets scared. This is a normal reaction to stressful situations called reflex bleeding. Releasing some of its blood is one way the ladybug can protect itself. The blood smells bad and signals to a predator that this ladybug is not a good lunch choice.
To prevent ladybugs from getting in, make sure all cracks around windows, doors, clap boards, pipes, ect. are sealed up. Some extermination companies offer this service, sometimes called inclusion. This, too, is no small project, and may cost a small fortune, but it’s worth it. Especially if you don’t like ladybugs joining you for dinner.
