Trap ladybugs in commercial beetle traps that do not contain pesticides. The trap contains a substance that attracts the ladybugs. When the ladybug enters the trap, it falls into the cone-shaped funnel that empties into a collection bag. The top of the bag is small and so it is difficult for the ladybugs to get out. Check the trap routinely to collect the ladybugs before they get out of the bag.
