Although a hole in one's yard can be taken as evidence of a snake den, according to extension advice, this assumption is not always true. Snakes rarely dig holes on their own. They tend to take advantage of pre-existing holes made by other creatures or even natural holes in the soil. As explained in city publications like the City of Hampton and the University of Illinois Extension, snakes like to inhabit pre-existing holes, empty spots underneath debris, or open spaces near buildings. Consequently, the attention is shifted from the actual snake to the original creator of the hole. Most of the time, it is a mammal, like a rodent or another ground-living animal, that digs holes. Just having holes in the yard is not proof that snakes have been present in the yard.
The Surrounding Environment Matters More Than the Hole
Recommendations include considering factors other than the entrance itself to determine the presence of snakes. Advice offered by the Utah State University Extension and Colorado State University Extension notes that snakes will be drawn to an environment that offers both food and cover. Characteristics like dense foliage, woodpiles, rocks, mulch, and the presence of rodents make for an ideal environment for seeking refuge and prey. Thus, a garden containing such elements will offer a greater likelihood of supporting snake life, irrespective of who dug the hole. The hole is thus one factor among many others that will create the overall habitat. Recommendations based on scientific research indicate that snakes respond to ecological factors without changing the environment themselves.

How Can You Assess Risk Without Guesswork?
Establishing the presence of a snake within a hole is a process that needs practical consideration of observable factors. According to the University of Florida IFAS Extension, the entrance shape, the condition of the soil around the hole, and any traces of animal footprints help distinguish between a mammalian burrow and a hole dug by other animals. More reliable evidence of snake presence is the frequent observation of snakes in the area, rather than the hole itself. Another piece of advice comes from the University of Nebraska Extension. They state that direct observations of snakes are more reliable than indirect evidence. The point here is simple. While a hole may provide clues to a snake's presence, it does not constitute evidence on its own.
