>> in your experience are organic methods for SHB control effective?

Umberto,

I've only a few years experience, but here is a non-chemical method that has worked for me:

Let a banana get so ripe that it turns to liquid and squeeze that through a strainer.  Then add an equal amount of apple cider vinegar.  Add that mix to 16 oz. of vegetable oil in a discarded dish detergent bottle.   The banana juice and apple cider vinegar don’t mix with the oil so you have to shake it up before squeezing some into the traps.  About 8 mm of the mixture in the bottom of the trap is sufficient.

I use the beetle blaster traps seen on this page:

My hives are kept in almost full sun but do receive a little late afternoon shade.  I try to not add any more space (boxes) than the bees can easily patrol.  I help a few other beekeepers with their bees and I consistently notice more beetles in the hives that have screened bottom boards compared to the ones with solid bottoms.

Regards,

Kevin
