Hello all on the list, I have a question pertaining to the use of the ultrasound insect repellers designed to use in the home. I also use them in the honey equipment storage area for cricket control (seems to work ok) and was wondering if anyone has any experience with them in close proximity to a colony of bees? Maybe next to an oberservation hive? I realize that bees dont hear but was wondering if one of these devices would confuse or otherwise effect them. Any input would be appreciated. thanks in advance Al Boehm Columbus N C USA
