Characteristics
– 
Size: Ranges up to 1 inch in length. Color:
Usually black with yellow stripes on the thorax
and abdomen.
Often confused with carpenter bees, bumblebees
are characterized by the hairiness of the abdomen
(carpenter bees have a smooth abdomen).
Behavior –
As social insects, bumblebees live in colonies.
Each spring a queen that has survived overwintering
will find a suitable nesting site and establish
her colony. Her first brood of eggs mature into
workers that forage on pollen and nectar for food.
The workers do produce honey, but it is not edible
to humans. The colony grows larger over the summer
and is usually discovered by a homeowner while
gardening or mowing the lawn. The bees will attack
to defend their nest, so they are considered a
health concern. During the fall, the colony produces
a number of queens that fly out to find protected
sites to spend the winter and thus repeat the
cycle next year.
Habitat –
Bumblebees live in colonies, in old rodent burrows,
or other cavities within the ground. Occasionally,
bumblebees will establish a nest above ground
in a wall, firewood pile, shed, crawl space or
attic.
Tips for Control –
- To prevent bees from establishing nests
on a property, fill in all animal burrows
and holes in the soil.
- Seal holes in the building's exterior and
ensure that all vents have tight-fitting screens.
- When a nest is discovered in or around a
home, a professional should be contacted to
treat the nest.
