Species: Bombus impatiens (Common Eastern Bumblebee) 

Package: QUAD pollination unit containing four temperature insulated bumblebee hives, each containing a vacuum sealed bag holding supplemental sugar water solution. 

Contains: Each bumblebee hive contains approximately 250 workers, a reproductive queen, and developing brood (eggs, larvae, and pupae).



Place QUAD evenlly throughout the field. Use a pallet.

Place the QUAD hive doors orientated away from prevailing wind or protect with a windbreak.

Place in a field 5-10 days before bloom.

Open the entrance of each hive by pulling the sliding door up.

A paper mesh covers the exit, and the bees will chew through this mesh before they leave the QUAD. Do not remove this mesh.

In warmer climates, a shade structure over the unit is recommended to protect the hives from the afternoon sun. This may not be needed in early spring crops (blueberries, haskaps, apple, etc.)



QUAD bumblebees perform at ambient temperatures of 50-82°F (10-28°C). Bumblebees will forage at temperatures above and below this range, but at reduced levels.

Bumblebees can be used in conjunction with honeybees, but should be placed at least 100 meters from honeybee hives to prevent honeybees from raiding the bumblebee nests.

QUAD units are attractive to large mammals such as bears. If bears are a concern, surround the QUAD units with electric fencing available from agricultural suppliers.


Moving QUADs

QUAD units can be moved between fields. However, prior to moving the units to another location it is important to allow all bees to return to their hives.     

QUADs can be moved by closing the door to the ‘’in-only’’ position 24 hours prior to moving to the new location. Some bees are typically lost with each move.

Precaution: Use a bee-suit if possible to move the QUADS.

Check local government regulations regarding the transport/movement of bumblebees.


Chemical Usage   

Bumblebees are susceptible to various chemicals, as are other pollinators. Detailed and current information regarding side effects and appropriate measures are available at

Before using incompatible pesticides, hives must be closed and removed from the treated area. This should never last longer than 2 days, as the colony will suffer from starvation and mortality of larvae due to lack of pollen.
