Bumblebees, Bombus impatiens for pollination For Discount

The bumblebee hives are constructed of cardboards and plastics. These hives are completely self-contained and sold with their own food source. Growers should release bumblebees in the greenhouses shortly after the appearance of first flowers. Generally bumblebees perform better under optimal greenhouse conditions and they remain active even at cold temperature as low as 41°F but their activity is completely reduced by extreme hot temperature. When placed out-doors, make sure that the bumblebee hives should be sheltered properly from extreme and cold temperatures. In the greenhouses, the hives must be placed above the ground to protect from irrigation water and blowing air from fans.

Make sure that bees in hives are settled down before opening of the small doors otherwise they will become violent and possibly start stinging. If someone is allergic to bee stings then that person should avoid going near to bumblebee hive. Non-allergic people can work freely and calmly around bee hives.

Bombus impatiens can be used in all states except in Oregon where they are prohibited, in Washington they can be used only in screened structures and in California growers need state-issued permits.
