Phil Bartosh on Swarms in May.
May has been swarm month, during inspections in May I have have found 30 to 40 swarms cells, found hives that appear to be queen less most likely because the hive swarmed, All the local clubs stress inspections every 7 to 10 days. If you inspect every 21 days a queen can be hatched in 16 days and the hive swarms without you knowing it. Remember in Cuyahoga County we are basically urban beekeepers and swarms are a threat to local beekeeping. We have had two communities pass bee laws allowing beekeeping in the last 2 years. Unwanted swarms in a neighborhood can results in laws that can end beekeeping with a stroke of a pen. Please remember just adding deeps or supers do not stop a hive from swarming, Adding 2 or 3 boxes to a hive to try to prevent swarming also give hive beetles a place to hide. If your testing and treating for mites follow the instructions exactly on the label of your product. The link for Formic Pro is http://Nodglobal.com
