These beetles are harmless to humans. In facts, ladybugs, also called lady beetles, are very beneficial to agriculture and gardens. Ladybugs feed on harmful aphids and scale insects associated with trees, shrubs, bushes, flowers, and many agriculture crops. With these benefits in mind, ladybugs can still be a problem for homeowners. If ladybugs have been entering your house, the best method you can adopt is prevention.
Ladybugs enter through cracks around windows, doors, siding, pipes, and other openings.
If ladybugs can enter your home, then so can cold air in the winter and warm air in the summer. You should fill in any cracks and repair any damaged window or door screens. Then you may place the beetles under a bush or other covered area well away from your home. Remember, they will be invaluable to your garden and flowers next year.
