How to Deter Ladybugs
- 1). Seal up doors and windows. Ladybugs can enter homes through cracks. Applying weather stripping to windows and doors keeps ladybugs from getting inside.
- 2). Spread diatomaceous earth around the perimeter of the house. Diatomaceous earth is an all-natural insect repellent that is safe to use around humans.
- 3). Spread insect killers such as boric acid in places ladybugs are likely to walk. In order for this method to work, the ladybugs must walk across the boric acid.
- 4). Place a bowl of water mixed with a drop of soap in a well-lit place. By placing the traps in well-lit places, ladybugs are more likely to crawl into the water and drown.
