Ladybug Infestation

Not too long ago we were tearing out an old redwood deck in order to replace it with a new one. After removing the rotten joists, which were attached to the house, we found the largest ladybug colony I have ever seen. They had made their home in the wood of the house's band. Another insect had dug into the wood, making a maze of tunnels in which the ladybugs had proliferated.
