Snails are eating cucumber and other seeds

Due to the lockdown the domain investor tried to grow some seeds in one house she has access to . She found that almost no seeds are germinating.
After carefully checking the area, she found that small snails are eating the seeds
So though she is putting many seeds, not a single seedling has grown in that area.
In another place, where she has access, the germination rate is better, since there are fewer snails, and she is using waste to make the soil.
Many of the seeds are expensive, so all the money is wasted when the snails eat the seeds
