The rats with fancy tails will not eat daffodils. Toxic.

But when hungry and food is scarce they'll instinctively dig them up, chew
and spit them out and leave them to rot.

It's very difficult to rid an area of an established squirrel population.
They are there because the location is hospitable for "housing" and most
times there is water nearby and a steady source of food. Trapping squirrels
won't work, more will take their place. Shooting at them is just as bad,
more will come, but by shooting sooner or later you'll **** off a neighbor
who will frag you with buckshot. And it's not possible to selectively
poison squirrels, you will also poison many other crtters including domestic
ones, even the carrion eaters... mice will take the bait, seek refuge in
your abode where your cat who never goes outdoors will in turn become
poisoned and very likely die. Setting out poison bait is always the dumbest
of all possible solutions, in fact it's no solution at all, unless you eat
it. There are really two choices, feed the squirrels or don't plant bulbs.
