Time their emergence, with your Garden’s opening blooms.
Development is dependent upon temperature:
Adults emerge after about 20 days at 84 degrees F
Adults emerge after about 42 days at 70 degrees F
If you haven’t purchased your bees well ahead of time don’t worry, we put ten or twenty days on our cocoons before we send them out. You can also keep them in the house, to speed things up. Place the Hatching Tube in a warm location that may be close to, but not on, a heater vent. Every day in the house is like two days outside.
Bee larva inside your cocoons can’t regulate their temperatures so if it’s above 90F, bring them indoors and release adult bees as they emerge (in the early morning) or put them back when the temperature drops.
Keep cocoons out of the direct sun but facing the morning sun. The warmth will get them up and moving earlier, which will boost pollination.
Install the bee house on a wall, fence, or tree – bees do not like to sway in the wind.
Provide 1 nesting hole for each Leafcutter bee/cocoon, both male and female. Tuck the nesting block in the back of your house, as far as possible, to protect against wind and rain.
First-time leafcutter bee (Garden Bee) enthusiasts think that their bees flew away and are surprised a few days later by a leaf capped end. Give the bees at least two weeks to get settled.
Just as Mud is essential to Mason Bees, Leaves are Crucial to the Leafcutter bee: Leafcutter bees will leave your Garden if they can’t find their suitable leaves nearby.
Leafcutter bees like roses, Lilac bushes, hostas, dahlias, cherry trees, but best, is to plant a Pea plant next to your nest.
Bee activity usually stops in late August. This is when you will need to put in a little work. Collect and store the bees nesting blocks with the open ends up in a dry, secure building such as a garage or shed. The building does not have to be heated.
