I am currently battling the small hive beetle. I ordered a 5 frame Italian Nuc with laying queen back in April. Since I purchased the Nuc (from Georgia) It has been contaminated with small hive beetles. The feed store told me to keep them informed of the results, since they will reimburse me if my bees abscond.
I am treating the ground and I have a beetle Jail. I also have put cardboard in the screened bottom board with Diatomaceous Earth and I just changed the trap to taped down cardboard with a check mite + strip on the bottom plus DE. I've seen the flow video using the fluffy table cloth but I couldn't find this type of cloth at Walmart. I'm nervous about doing an oil/water pan or even the table cloth because my bees like to get through the screen and herd the beetles. My bees have expanded to 3 frames but I am still waiting till they are at 9 to add another brood box, plus I want to see less beetles.
I also treated the ground with a beetle pesticide. The beetle jail only had one beetle in it since I installed it. I pull out the bottom board regularly and brush off scattering beetles into a bucket of water and pesticide. Then I wait around and kill the ones that try to fly back in with my hive tool. I've killed too many to count. Bees still look good except I accidentally spilled apple cider vinegar from the beetle jail in my hive, hoping I didn't harm the queen.
I am only buying future bees from a local supplier in the future. BTW my hive is in the woods with dappled sunlight. That is the only place I have to work with, so full sun is not an option at this juncture.
That's my story so far, any thoughts or advice would be appreciated.
