8 Snakes Commonly Found in American Backyards

Most snakes located in American gardens are small, harmless, and very attached to the ground environment. As per wildlife advisory and extension recommendations, gardens replicate natural environmental factors like moisture, shelter, and food sources, making them functional environments for snakes. Hence, the type of snakes encountered in residential backyards will be common, predictable, and not random. Garter snakes, brownsnakes, ring-necked snakes, and smooth greensnakes are some of the most commonly observed snakes in residential yards. In addition to these, other commonly identified snake types are Dekay's brownsnake, rough greensnake, red-bellied snake, and sometimes young rat snakes. All these snakes have similarities in their appearance and behaviors, which is why people find it difficult to distinguish between them. Identifying a snake is not the problem; distinguishing it from another is the issue. Most of the mentioned snakes have stripe markings or dull colors. They may look alike in a few seconds' encounter. Wildlife departments confirm that colors are among the least accurate snake identification criteria.

The 8 Snakes That Show Up Most Often

1. Garter Snake: Most likely the most frequently encountered among the three states of Massachusetts, Illinois, and California. Striped, adaptable, and nonvenomous.


2. Brownsnake (Dekay's): Small-sized, commonly located under the soil or leaf litter, and hard to notice due to its subtle brown coloring.

3. Ring-necked Snake: Characterized by a brightly colored neck band, and commonly spotted when handling debris or stones.

4. Smooth Greensnake: Bright green and slim; commonly mistaken for something else due to its bright coloring.

5. Rough Greensnake: Resembles the smooth greensnakes, yet is slightly bigger and more coarse.

6. Red-bellied Snake: A small-sized snake with a clearly distinct underside.

7. Young Rat Snake: The young specimens significantly differ in appearance from adult snakes, resulting in frequent confusion.

8. Earth Snake/Worm Snake: Tiny in size, and often confused with worms instead of snakes.

A key commonality among these species lies not only in their appearances but also in their habitats. The research and extension literature indicates that gardens with mulch, boards, rocks, and moisture provide ideal hiding places. The presence of these species should not be seen as accidental; these animals use the garden just as they do their natural surroundings.

Why Identification Is Harder Than It Looks

The problem is overlapping. There are similarities in size, color, and patterns among most of these species. A striped body may mean that it is a garter snake. However, factors like lighting, age, and regional variability may influence the appearance of this trait. In addition, there are a lot of small brown snakes, which may be identified as representatives of several different kinds of snakes. The wildlife sources state that it is important to recognize several characteristics together when identifying a particular species. The size, pattern, type of the head, scales, and location may be clues for correct determination. A snake found underneath a board in moist earth is quite different from the one seen in the grass. The last aspect concerns visibility. Many of these species are shy and spend much time underground. They can be encountered during disturbances such as gardening. Thus, they have fewer chances to be seen in a natural habitat. All in all, the message seems quite clear and practical. Almost all snakes encountered in U.S. gardens are non-poisonous, yet it is impossible to determine the species without additional research. It is because gardens cannot be viewed as human zones only.
