Paul from Butler, Ky writes,
Can or should I use Demand CS with Delta dust for carpenter bees?
You should use Demand CS in conjunction with Delta Dust for carpenter bee control. Spraying Demand CS topically will help stop new bees from coming in and drilling holes. You should mix Demand CS according to the product label and apply the spray to surfaces where the bees are known to land or drill.
