2964Re: [beemonitoring] bumble bee nest excavation
- Oct 16, 2013All kinds of materials have been used to make casts of bee nests (plaster of paris, molten metal, plastics et cet) but these are not likely to be very useful for something like a bumble bee nest where one is interested in the arrangement of the cells and honeypots within a larger cavity. A standard non-destructive technique for excavating burrows of ground nesting bees is to blow in fine dust (talcum powder, colored chalk dust or the like) so one can follow the main burrow, taking care on the way in not to destroy any auxillary structures. You'll probably have to poison the colony as the bees are not likely to be pleased by your destruction of their nest but once you get to the main chamber you should be able to remove it in one big piece (if you dig a big enough hole around it). Hard or rocky soil could make this a problem.bestJackJohn L. Neff

I've done some straight up digging up of bumble bee nests in hard soil with deep narrow entrance tunnels that were easy to lose track of while digging. It didn't work well.
So my helpful suggestion is to find nests in soil that isn't totally compacted and with entrance tunnels that are less than 1m.
