We'd keep it quiet and clever. First, lay a thin layer of sweet-smelling herbs – their scent will keep them distracted. Then, under the floorboards, we set up a shallow pit with a soft rope rope, so if they step on the loose boards they’ll slip and tumble into the pit, but not hurt. Next, a small trapdoor in the back entrance, so we can pull it open from the inside and send a bucket of water from the pantry to soak the goblins’ boots, slowing them down. Finally, a handful of false crumbs leading to a hidden chamber where we can hide and wait. All we need are a few sticks, a bit of rope, and our old cooking pots – no big effort, and it keeps the goblins off our doorstep.
