Spring sees the common honey bee swarming as new nesting sites for new colonies are sought. A bee swarm can be very upsetting and, occasionally, dangerous. Bees are endangered so ought not to be killed under normal circumstances, but pest controllers can help with practical advice and solutions. Multiple bee stings are painful and can be very serious so there are Health and Safety concerns over bee colonies in some areas.
Bumble Bees can also sting and often colonise bird boxes, compost bins or gaps under garden sheds and can be a nuisance. They are also good pollinators and endangered but their colonies can often be relocated to safer locations.
