In my experience, they don't eat daffodils, as they are poisonous. Tulips are trickier, mostly I plant so many, they can't get them all. But some people have luck planting them with something spiky, like ground up shells. They hurt to dig up then. Or there are wire cages you can buy for tulip bulbs. I never thought that was worth it, as most tulips are basically annuals, except Darwin hybrids and even those are mostly a couple of years.
But daffodils and hyacinth get better every year and don't get eaten.
