Bumblebees

Identification

  • Colour Black and yellow
  • Size 10 to 25 mm in length
  • Description Bumblebees are beneficial social insects known for pollinating crops and wild plants. They are found throughout Canada in abundance. Of the over 200 known bumblebee species worldwide, approximately 50 are found in North America. Bumblebees are sometimes mistaken for the carpenter bees. Bumblebees have hairier bodies than carpenter bees, which have a solid colour and possess solid black abdomens. Bumblebees are annual nesters that build new nests each spring as opposed to reusing ones from the previous year.

General Facts

Why do I have bumblebees?

Bumble bees typically nest on or below the ground but may still find opportunities to come into contact with humans. The insects expand the nest as the colony grows and may interfere with efforts to mow or treat the yard. Homeowners may notice visible wax, developmental cells, and honey stores, which sometimes appear similar in size and shape to brown or orange grapes arranged in small bunches. Similar to other bees, the bumble bee makes an audible buzzing sound and may swarm, though typically only when defending the nest. The most regularly occurring sign of a bumble bee infestation remains sighting the nest or the bee itself.

How worried should I be about bumblebees?

Bumblebees are beneficial and less aggressive insects. They only become a problem when provoked. The most significant danger bumblebees pose is the threat of stinging, though the insects typically only sting when defending the nest. Unlike other bee species, bumblebees can sting more than once, as the stinger is smooth, contains no barb, and typically will not fall off or get stuck in the skin. The sting of a bumblebee may be painful and could lead to hospitalization if the victim is allergic to bee venom. Although they are commonly mistaken for carpenter bees, bumblebees typically do not damage man made structures even when nesting near homes.

How can I prevent bumblebees invading?

To avoid interactions with bumblebees, home and business owners should continually get rid of all organic debris from yards and areas close to the structure. Bumblebees may also nest in hollow spaces on decks, patios, and even in the eaves of the home. In order to successfully handle a bumble bee infestation, consider contacting a pest control specialist with the knowledge, experience, and equipment to remove the insects from homes and businesses safely.
