Dust works..verdict still out on cyonara 9.7
By Mike on 05/09/2013
The dust will kill bees that are in the hole and that have been direct contact with the dust. Dust doesn't seems to be killing any bees that enter the holes after initial dusting. The cyonara does nt appear to be preventing the bees from drilling new holes. The cyonara repels the bees for a day for so but then they are right back at it. I'm still using the products trying control my carpenter bee issue. I will update posting if things seems change.
