I live in a log home in Mississippi. Carpenter bees are borng into the fascia boards and rafters on my porch. This is an ongoing yearly problem. How can I prevent new boring sites each year?
This is easy to stop. First, treat any existing holes with DRIONE DUST right now. Seal them with some CORKS. Next, spray with CYPERMETHRIN or NBS to prevent any new ones from coming around. More details can be found in our CARPENTER BEE ARTICLE but this approach will take care of existing bee nests and stop new ones from coming around.
