I have fought beetles for the last 5 years,mainly in the shade.This year I set up 2 new hives on my 2nd floor porch(my wife was not very excited) that gets 8 hours sun.The difference is like day and night,very few beetles!
I have been seeing something interesting.
Last year I put a large piece of old carpet, upside down under my hives, so I would not have to mow around them.
I also run screened bottom boards.
Well this year, I am very, very hard pressed to find a hive beetle, and I got to thinking about he life cycle of the beetle. They require a pupation period in the soil.
I am wondering if the carpet is preventing the pupae from entering the soil?
Secondly, is the carpet presenting the pupae as a smorgasbord to my free ranging chickens.
