Experts swarm to help beekeepers

Keep swarms from being a problem

DEAN FOSDICK | Associated Press

When half or more of your honeybees have deserted the hive and are lingering nearby, who ya gonna call? Swarm chasers can provide quick help to fellow beekeepers, keeping them from getting stung literally and financially.

“A swarm is the division of the honeybee colony into two parts,” said Donald Lewis, a professor and Extension entomologist with Iowa State University. “One part of the colony will stay where they'll continue to grow, reproduce and make honey. The swarm leaves the colony in search of a place to set up elsewhere.”

Swarming generally occurs because the colony is crowded, or it could be caused by genetics, Lewis said. “There is a predisposition in some bee strains that makes it more likely for them to do that,” he said.

The likelihood that a swarm can become a thriving feral bee colony depends primarily on where their new home is, Lewis said.

“Here in the Midwest, if the swarm cannot get inside a protected location, they're not likely to make it through the winter.”

Beekeepers can prevent losing a colony by dividing it ahead of time; by re-capturing the swarm cluster and placing it in a new hive; or by buying a honeybee variety known for its low tendency to swarm, Lewis said.

If you've lost or simply spotted a swarm cluster, it may pay to find someone who, for a price or simply a new strain of honeybees, is willing to round them up.

Dan Maxwell, a beekeeper from Freeland, Washington, frequently responds to calls requesting help to remove swarms.

“I only work with honeybees,” Maxwell said. He won't deal with swarms that have collected too high (15 feet or more) or that are enclosed in ceilings, crawl spaces and brickwork like fireplaces. Those cases are “too much work, and it can be messy with brood and honey,” he said.

“These are beneficial insects,” he said. “You don't have to needlessly kill them. Simply give them a wide berth and chances are, they'll be gone in a day or two.”
