The ladybug life cycle explained above is normal, and though it will give you some extra work, you can do your own ladybug pest control. It is fortunate that this get into your house just to hibernate, not to multiply their species. Therefore, you might only need to vacuum you house more frequent, and then putting the vacuumed bug outside. A precaution can be exercised too, by sealing the holes in your houses, just like under the door, window etc.
