How do you get rid of snail on your house wall?

To remove snails from your house wall, start by manually picking them off and relocating them to a suitable area away from your home. You can also create barriers using copper tape or diatomaceous earth, which deter snails from climbing. Additionally, consider using a solution of vinegar and water to spray on the affected areas, as the acidity can help repel them. Regularly cleaning the wall and removing any food sources will also reduce their attraction to your home.
