Thank you Gerald. Great information. Hopefully the property owner can be patient.

ACBA had a guest speaker last year who outlined the life cycle of bumblebees.  The program is in  the archive.
This is what I remember from it.
Their nests in the ground are almost impossible to excavate and relocate successfully.
(Entrances can be extended, and they adapt)
Nests are fragile.   If they are relocated they may not succeed anyway. Either that or they complete reproductive phase
of their life-cycle and abandon the hive,  so it may only look like they failed.   The host may never know.

When bumblebees get established in bird-houses, or something portable in the yard, they can be relocated with some success.
Some of our club members like to do that.

Bumblebees only operate a hive for a relatively small part of the year,   from the time they establish the colony in early spring
until they build up enough population to produce  the next generation of queens at the end of their brood cycle.
Once the queens hatch out, and leave the colony, (they mate and) they hide out in the environment until
they detect the triggers to begin of the next hive building cycle next year.

When I get calls, I try to encourage the caller into arranging things in the yard around the colony so that the
bumbles can complete the nest phase of their life cycle, and move out.
How long depends on species. I doubt that all species nest at the same time.

That's what I think I know about this topic.  corrections invited.

What can be done for bumble bees? I hope she doesn’t spray them.

No arrangements seem to have been made.

 

She called me to see what was up.

 

Who was going to handle this?

I'm close by and if unclaimed I can catch it.

Caller had a large redwood tree taken down. There was either a swarm in it or an established colony. There is now a large pile of branches and debris on the ground and the bees are hovering over a particular spot. Sounds messy. If you’d like to take a look contact her directly. I told her she might need to pay someone in protective gear to fish around in the Wood pile.
