He claimed that bulbs, when touched, even gently or when they grow
and touch a stone or some hard object, all exude an acid.
This is what animals such as rodents and deer etc can smell.
I didn't have the heart to say that still didn't explain why bulbs would
exude something that attracts animals to eat them and the audience was
getting a bit restive as it was just before tea time

In my last garden, I had a large woodland area smothered with bluebells and
daffodils. I also had grey squirrels, eight of them on one occasion. The
squirrels didn't appear to dig up any of those bulbs, yet I am sure they
feasted on my prized crocus bulbs nearer the house. Perhaps the crocus bulbs
exuded more acid allowing the squirrels to locate them. Very interesting!
