OK I have both, but it is not out of hand yet. I have done the Diatomaceous Earth around the hive, boric acid in political sign material (plastic) sealed with Crisco (stapled to base board), CD traps on top of frames in both brood boxes (1/4 c. soy flour, 2tbs. boric acid, 2 tbs. P'nut oil, & 1/8 c. Water), and have nematodes in route. Any advice on what else to do, while staying chemical free as possible? Since Houston does not have winters like up North our problem is a little bigger due to longer summers. 2 June was first hive start, but I do not want to loose my hive.
Thanks in advance.
