Well Jeff are you sure you really want to move those
bumble-bees?They tend to have a nasty temper!If you must,I
would recommend you NOT use a net as it would 1., harm the bees
and 2., result in you probably getting stung  a better plan
would be to dig the whole thing up and dump it quickly into
what ever you plan to use to observe them.While they may be
upset in the short term,I think this would be much less
stressful to you and the bees!
