The Reality of Serpent Shelters: Do Snakes Actually Dig?
Before we dive into the visuals, it is important to understand a fundamental fact about snake behavior. Most snakes are not physically equipped to dig their own burrows in packed soil because they lack the necessary limbs or claws.
Instead, snakes are opportunistic residents that move into abandoned homes left behind by other animals. They frequently take over tunnels created by rodents, crawfish, or large insects to escape extreme temperatures or predators.
When you ask what do snake holes look like, you are usually looking at a repurposed rodent run or a natural crevice. The snake simply modifies the entrance through frequent use, smoothing out the edges as its body slides in and out.
For a homesteader or camper, this means that a “snake hole” is often a sign of a larger ecosystem at play. If you have a high population of voles or mice, you are much more likely to find snakes utilizing those existing underground networks.
A Visual Guide to what do snake holes look like in the Wild
Identifying these openings requires a keen eye for detail and an understanding of local wildlife. While there is no single “standard” look, several consistent features can help you identify a potential snake den.
Size and Diameter
The size of the opening is often the first clue to the size of the inhabitant. Small garter snakes may use holes only an inch in diameter, while a large rattlesnake or bull snake might require an opening three to four inches wide.
Look for a hole that matches the girth of the snakes common in your region. If the hole is significantly larger than any local snake, it is likely still being used by the original mammal architect, such as a groundhog or a fox.
The Shape of the Entrance
Unlike many rodent holes that can be somewhat irregular, snake-occupied holes often have a circular or oval appearance. Because the snake’s body is cylindrical, the constant friction of entry and exit rounds out the edges of the soil.
You might notice that the entrance looks “polished” or exceptionally smooth compared to the surrounding dirt. This is a result of the snake’s scales buffing the soil every time it enters or leaves its refuge.
The Absence of Mounds
One of the most telling signs of a snake hole is what is not there. Because snakes do not dig, you will rarely see a fresh mound of loose dirt piled up around the entrance of the hole.
If you see a large pile of excavated soil, you are likely looking at the work of a mole, gopher, or squirrel. Snakes prefer clean, unobstructed openings that allow them to slip inside quickly when they feel threatened.
Differentiating Snake Holes from Other Animal Burrows
To stay safe and avoid unnecessary worry, you must be able to tell the difference between a snake’s hideout and the home of a harmless insect or a busy mammal. Misidentifying a hole can lead to missed safety precautions or unnecessary pest control.
Rodent Burrows (Mice, Voles, and Rats)
Rodent holes are the most common “fake-outs” for outdoor enthusiasts. These holes are usually two to three inches wide and often have bits of nesting material, like dried grass or leaves, tucked near the entrance.
You may also see small, pill-shaped droppings near the opening. While a snake might be inside waiting for a meal, a hole with active rodent signs is technically a rodent burrow first.
Crawfish Chimneys
If you are camping near a river, lake, or marshy area, you might see strange, vertical tubes made of mud pellets. These are often mistaken for snake holes by beginners, but they are actually crawfish chimneys.
These structures can stand several inches tall and have a distinct “bubbly” texture. Snakes do not build these, though they may occasionally hide in the water-filled burrows if the crawfish has moved on.
Insects and Arachnids
Small holes, roughly the size of a pencil or a nickel, are usually the work of insects like cicada killers or solitary bees. If the hole is covered in a thick layer of silk or webbing, you are looking at a wolf spider or funnel-web spider burrow.
Snakes do not produce silk, so any presence of webbing is a definitive sign that the hole is occupied by an invertebrate rather than a reptile. However, always keep your fingers away regardless of the inhabitant.
Secondary Signs of Snake Presence Near Burrows
Visualizing what do snake holes look like is only half the battle; you should also look for environmental clues that confirm a snake is currently using the area. Snakes leave behind “calling cards” that are easy to spot if you know what to look for.
Shed Skins (Exuviae)
Finding a translucent, papery skin near a hole is the most obvious sign of snake activity. Snakes often use the rough edges of a burrow entrance or nearby rocks to help snag their old skin and peel it off.
If you find a shed skin, look at the pattern. Even without the color, the scale texture can often tell you if the snake is a non-venomous species or something more concerning like a copperhead.
Belly Tracks in the Dirt
In soft sand or loose soil, snakes leave distinct tracks. These aren’t the footprints we are used to seeing from mammals, but rather long, winding “S” curves or straight drag marks known as rectilinear motion.
Check the dust around the hole entrance for these smooth paths. If the tracks are fresh and lead directly into the opening, there is a high probability that the resident is currently “at home.”
Snake Scat and Odor
Snake droppings are often dark, elongated, and may contain bits of bone or fur from their prey. They also frequently contain a white portion called urates, which is similar to bird droppings.
Additionally, some species, like the black rat snake or certain pit vipers, can omit a musky, unpleasant odor when they feel threatened or are nesting. If a hole smells like “skunky” rotting vegetation, it might be an occupied den.
Safety Protocols: What to Do If You Find a Snake Hole
Whether you are a solo hiker or a homesteader, safety should always be your primary concern. Discovering a snake hole doesn’t mean you need to panic, but it does mean you need to adjust your behavior.
- Maintain a Safe Distance: Never lean over a hole to get a better look. Some snakes can strike from a coiled position covering a distance of half their body length or more.
- Do Not Poke the Hole: A common mistake is using a stick to “see if anything is inside.” This can agitate a resting snake, causing it to bolt out of the hole toward you.
- Wear Protective Footwear: When walking in areas with high burrow density, always wear sturdy leather boots and long pants. This provides a vital layer of protection against accidental defensive bites.
- Use a Flashlight: If you must inspect an area near a hole, use a high-lumen flashlight from a distance. Never reach your hands into dark crevices, under logs, or into holes where you cannot see the bottom.
If you find a hole directly in your planned campsite, the best course of action is to move. It is far easier to relocate a tent than to spend the night wondering if a curious serpent will emerge under your rainfly.
When to Call a Professional
For homesteaders and RV owners parked long-term, snake holes near the foundation or “skirting” of the vehicle can be a concern. If you suspect a venomous snake has taken up residence near your living space, do not attempt to flood the hole or use mothballs.
Mothballs are ineffective and toxic to the environment. Instead, contact a local wildlife relocation expert. They have the specialized hooks and tongs necessary to safely remove the animal without harming it or risking a bite.
Park rangers are also excellent resources if you find a den on public lands. They can tell you if the hole belongs to a protected species and whether that specific trail or campsite needs to be temporarily closed for safety.
Essential Gear for Snake Country
If you frequently explore areas where snakes are common, having the right equipment can provide peace of mind. You don’t need a full survival kit, but a few key items make a big difference.
- Snake Gaiters: These wrap around your lower legs and are made of puncture-resistant material to stop fangs from reaching your skin.
- Trekking Poles: Use these to probe tall grass ahead of you. The vibration can often alert a snake to your presence, giving it time to retreat into its hole before you arrive.
- First Aid Kit: Ensure your kit includes pressure immobilization bandages, though the best “first aid” for a snake bite is always a cell phone to call emergency services and a set of car keys.
Frequently Asked Questions About what do snake holes look like
Do snake holes have spider webs over them?
Generally, no. If a hole is covered in a functional spider web, it is unlikely a snake is using it regularly. The snake’s movement would tear the web every time it passed through. However, a very old, abandoned web might persist near the entrance of a hole a snake has recently claimed.
Will a snake hole always be in the ground?
Not necessarily. While we often think of holes in the dirt, snakes also utilize “holes” in rock piles, hollow logs, and even the gaps in stacked firewood. On a homestead, they may use the gaps between cinder blocks or under a concrete porch.
How deep are snake holes?
The depth depends on the original builder of the hole. Some rodent tunnels can go several feet underground and feature complex chambers. Snakes will go as deep as necessary to reach a stable temperature, especially during winter hibernation (brumation).
Can I fill in a snake hole to get rid of them?
Filling in a hole is rarely a permanent solution. If the food source (rodents) is still present, new holes will appear, or the snake will simply find another way out. It is better to focus on rodent control and clearing debris like tall grass and woodpiles to make the area less attractive to snakes.
Staying Safe and Informed Outdoors
Learning to identify the landscape is a core part of becoming a seasoned outdoor enthusiast. Knowing what do snake holes look like allows you to respect the wildlife around you while maintaining your own safety boundaries.
Remember that snakes are a vital part of the ecosystem, acting as natural pest control for the very rodents that often carry diseases. By observing from a distance and choosing your paths wisely, you can coexist with these fascinating creatures on your next journey.
Stay observant, respect the burrows you find, and always keep your boots on when trekking through the brush. Safe travels and happy exploring!
