Once carpenter bees have made their holes, it is best to dust them with Delta Dust Insecticide & then seal up the holes 2 weeks later. You can also apply a product such as Demand Duo Insecticide before they make their holes to try & prevent them. All products needed for proper carpenter been prevention & control can be found in our Carpenter Bee Control Kit.Â
