Moles don’t actually eat bulbs, they eat earthworms, grubs, and other bugs. Gophers eat bulbs, squirrels can dig them up too. Earthworms obviously are good, so its bad that moles eat them, grubs however eat plant roots, often causing bare spots in lawns.

One way to get rid of grubs is with milky spore bacteria, which is an all natural solution that lasts for years and years and only targets grubs. However, if that isn’t your thing there are synthetic solutions sold at home & garden centers — these could also kill other things like earthworms though.

Anyways… often if you get rid of the grubs you’ll get rid of the moles. Hasn’t worked for me yet but that is what I hear.

What I really hate about moles is the barespots they make by pushing up mounds of dirt, the raised tunnels, etc. They don’t actually eat plants, but putting those gapping gaps in the soil has to stress plant roots eventually.

Assuming what you actually have is gophers and not moles, one solution is to plant daffodils. They’re toxic to gophers and so they act as a repellent (kinda like using marigolds around the border of your veggies to repel rabbits).
