You can catch fruit flys in your house with a paper funnel resting in the mouth of a jar with apple cider vinegar in the jar at a level to almost meet the hanging funnel. The fruit flies go in and die in the vinegr bc they cant get out.
So, If I was to make such a contraption and place it next to the hive, I am sure it would catch SHB but would it actually DRAW more SHB since its sitting ouside the hive in the open?
I had a bad beetle problem last year so I moved my hive to an 20x15 concrete pad this year and I still have lots of SHB. The hive gets sun from 10am on. I cant see the beetles leave during the day but at night near closing time (last call), they come flying into in the hive in a regular stream. I assume they are escaping the heat of the hive during the day.
Anyways, I thought I could put that fruit fly idea out by the hive and see what i catch. At worst case scenario, I could just put it out during last call and bring it in afterwards so it doesnt stay out there all the time.
I put my hive on a concrete pad too bc I thought that without dirt there would be less. I know they can travel long distances but I have just as many SHB as when they were over dirt so dirt definitely doesnt increase chances of having SHB.
I just wanted to see if anyone else had tried the fruit fly trap idea already and if it attracted even more SHB
