There are a lot of different options. The first thing you need to determine is whether you want an organic or synthetic option.
If it's going to be your primary defense against moles, stick with organic solutions since they're more effective and typically safer for people and pets as their main ingredient contains castor oil, which has been used in home remedies several times throughout history thanks to its natural effect on moles.
However, if you have a large area that requires protection from moles, consider applying Tomcat Mole & Gopher Repellent Spray every few months after raking up dead grass clippings, so it can soak into the soil where m will probably try digging later on.
