ladybugs

There are hundreds of ladybugs in J.B.'s house....they gather in the cozy corners of sunny windows. I looked up 'ladybug behavior' to better understand why, this is what I found:

"Ladybugs are attracted to 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."
