I have mixed this at 1/2 oz per gallon of water. I sprayed there area of living twice. Today I mixed some up and actually sprayed them while they were flying/hovering around there nests and most of them shook it off like it was nothing. I may have killed one or two but what gives?
Cyzmic CS Micro-encapsulated Insecticide does not kill on contact. The insect has to ingest the product or it has to make its way through the follicles into the insect. It does not sound like it has been enough time to knockdown the population. We also recommend to dust in the holes that are bored so that the larvae would be killed. Be sure to review our Carpenter Bee Guide.
