Lots of insects and animals swarm.
This page is about honey bee swarms and what you can do if one arrives in your garden. The Swarm Center is a phone number list of beekeepers in Rhode Island who will come and remove the swarm. The list shows all the phone numbers and all the towns that each beekeper can travel to.
Some beekeepers charge a fee for swarm removal, especially if it involves carpentry or some other repair. Be sure to ask the beekeeper before inviting him or her to remove the swarm.
NOTE: the Swarm List is being updated for Spring 2013 season. It will be posted soon.
