So, dirt mounds. We have to go into quite a bit of detail about this, to know what pest you have. Only a few animals create these, so we can determine that you’ll commonly have moles OR gophers. The mounds can range in size though. There are a few details you need to check out for to know if it’s a gopher. Firstly, when a gopher creates a mound, it should push out the dirt in a pattern much like a fan, so it will try to spread the dirt evenly above the ground. If you see conical mounds, that splay in a single direction, then you have a sure sign of moles, not gophers. Remember that gophers can push dirt in all directions, so this isn’t a dead giveaway. In doing this, the dirt around a gopher hole is typically finer (smaller grains) than moles, which can be a good tell-tale to the creator of the hole. Also, gophers tend to be more attentive, so they will plug up the entry holes they create. If you notice any burrow-holes which seem to be plugged up, you’ll recognize that it is a gopher as opposed to other pests. On top of this, they create several holes close together, so if there’s a group of about 6 holes, you can safely assume gophers are present. If there has been recent lawn-mowing, you may instead find dry patches of dirt on the lawn.
