Will Bifen IT kill bumble bees nesting under my deck? I can not see the nest, and I will have to broadcast....
Yes. If the bumble bees come into contact with the Bifen IT, they will be killed. It is important to make sure you are spray areas that they will actually land on. We also recommend either treating very early in the morning or late in the evening when the bees are less active.
