Butterflies and bees are insects and would be affected by LambdaStar 9.7% CS Insecticide in the same way the target pests like ants and spiders would be. The best way to reduce the chance of harming the bees, butterflies, or other beneficial insects is to spray later in the day when they are less active, and try to avoid spraying blooms of flowers and plants they would be using for pollenation.
When using LambdaStar 9.7% CS Insecticide, it can take minutes to hours to kill millipedes that have contacted the treated surfaces.
