Snakes in Home: What to Do and How to Keep Them Out

You walk into the laundry room at night and notice something moving beside the washer. There's a snake against the baseboard, and your first instinct is to reach for a broom. Leave the broom alone. You don't need to identify or catch the animal before making the room safer.

Once everyone is out of reach, treat the sighting as more than a removal job. A snake inside is a reason to investigate an entry route and a possible food source. Getting it out matters. Finding what allowed it in is what makes the repair useful.

What to Do in the First Minutes After You Spot a Snake

The United States records an estimated 7,000–8,000 venomous-snake bites annually, according to CDC guidance on venomous snakes. That figure covers bites, not snakes entering homes. It doesn't tell you whether the animal beside your washer is venomous.

Your immediate job is to avoid a close encounter. Cornering, stepping on, or trying to move an unidentified snake creates unnecessary risk.

Make space before making decisions

1. Move people and pets away. Leave the room and close the door if you can do so without approaching the snake. Don't reach past it to get to the handle.
2. Back away and leave it room. Don't pin it with a broom, pick it up, or grab its tail. A snake can turn and strike the hand holding it.
3. Watch only from a safe position. Note its approximate length, body shape, color pattern, and direction of travel. You're collecting information, not testing its behavior.
4. Use your camera's zoom. Take a photograph only if you can stay well back. A closer picture isn't worth approaching an unidentified animal.
5. Contact animal control or a licensed wildlife professional. Describe where the snake is and whether occupants can remain separated from it. Don't begin an improvised capture while waiting.
6. Record the last location if it disappears. Mark the spot with tape once it's safe to approach the area. Keep your hands out of openings, behind appliances, and under stored items.

Don't move the washing machine or empty a closet to keep the snake in sight. If watching requires getting closer, step away instead. Tell the responder where you last saw it and which nearby openings it could have reached.

Immediate distinction: A snake in an open room is a removal problem. A snake that has bitten someone is a medical emergency.

If a bite has occurred, stop the removal effort and call emergency services. Nobody needs to capture the animal before the injured person receives help.

How to Identify the Snake from a Safe Distance

Species matters more than size. A small snake isn't automatically safe to handle, and a thick-bodied snake isn't automatically venomous. Use appearance to help a qualified person identify it, not to justify moving closer.

From your existing position, record stripes, blotches, crossbands, overall color, and body thickness. Note a visible neck ring or tail rattle, but don't manipulate the animal to inspect its belly or tail. The Connecticut DEEP guide to local snakes provides regional identification context.

Common Connecticut snakes found indoors and how to tell them apart

This is a recognition aid, not an exhaustive list of Connecticut snakes or venomous species. A snake that doesn't resemble the timber rattlesnake row isn't thereby cleared for handling.

Defensive behavior also isn't a reliable identification test. Don't provoke a snake to see whether it hisses or changes posture. The guidance on snake hissing and what to do addresses that behavior without requiring closer contact.

A distant photograph can give animal control useful identifying detail. If the image is unclear or the identification remains uncertain, leave the decision to the responder.

When to Call a Professional Instead of Handling It Yourself

Connecticut guidance describes carefully containing a small snake with a bucket and cardboard while leaving venomous snakes alone. CDC guidance for wildlife around homes takes a more conservative approach: call animal control rather than trying to trap a snake yourself.

Those instructions serve different situations. The containment option depends on reliable identification, a suitable location, and someone capable of completing it without direct contact. Calling for help is the safer default when any of those conditions is missing.

Who to call, by situation

A child, pet, or vulnerable adult nearby lowers the threshold for professional help. If you can't keep everyone separated from the room, tell the responder that immediately. Don't assign someone to guard the animal at close range.

An animal that has disappeared hasn't necessarily left the building.

Hidden snakes need a different response from snakes resting in an accessible room. Don't dismantle ductwork, reach into a wall cavity, or seal the last visible opening. Explain the building layout and last sighting location when arranging help.

For repeat visits, request more than pickup. A removal appointment should also establish whether an entry-point inspection can be completed, so the animal's departure doesn't become the end of the investigation.

Bite Symptoms and the Legal Rules for Handling Snakes

Don't wait for symptoms to decide whether a bite needs medical attention. You may not know the species, and appearance alone doesn't establish how serious the exposure is. Call emergency services after a bite and follow the dispatcher's instructions.

Tell the dispatcher when and where it happened, what the person is experiencing, and whether the snake is still nearby. Share an existing photograph if requested. Don't return to the room to obtain one.

Keep first aid separate from capture

• Stop the encounter. Move away from the animal and keep other people out of the area.
• Prioritize medical instructions. Don't delay care while searching online for a species match.
• Avoid improvised treatments. Don't cut the wound, attempt suction, apply ice, or use a tourniquet.
• Leave identification to others. Nobody should attempt to catch or kill the snake for medical staff.

The WHO's snakebite-envenoming guidance establishes why suspected venomous bites require medical care rather than casual treatment. A household sighting may be manageable; a bite requires a different response.

Check wildlife rules before moving an animal

Connecticut protects timber rattlesnakes. Don't assume you can kill, transport, or release a snake wherever you choose. Check current DEEP requirements before any relocation, including after successful containment of a harmless animal.

Skip glue boards as a homeowner solution. Older extension guidance describes them as effective, but they create welfare and handling concerns. A stuck snake still requires removal, leaving an untrained person with another close-contact problem.

Legal compliance and occupant safety belong in the same decision. If either is uncertain, leave the animal alone and arrange appropriate help.

Find the Route and the Food That Drew the Snake In

A useful question after removal is: Why might another snake appear? The answer may involve mice as much as masonry. Snakes can enter buildings while following prey, so fixing the opening without investigating food access leaves part of the problem unresolved.

Rodents and insects can make buildings attractive to snakes, while brush, debris, and sheltered spaces provide cover. Colorado State University's snake-management guidance recommends combining habitat changes with physical exclusion rather than depending on repellents.

Trace the sighting back toward the exterior

1. Record the original location. “Beside the laundry-room pipe chase” is more useful than “downstairs.” Note nearby drains, doors, utility lines, and unfinished spaces.
2. Follow connected spaces. Inspect routes toward the basement, crawl space, or attached garage. Include utility penetrations, dryer vents, bulkheads, window frames, garage-door edges, and the foundation–sill junction.
3. Look for evidence of prey. Document suspected rodent droppings, gnawing, damaged packaging, or nesting material without disturbing it. Ask the inspector to assess uncertain signs.
4. Separate findings from assumptions. A nearby opening is a candidate route, not proof. Record it for inspection rather than immediately plugging it.

An outdoor hole deserves the same caution. Use this guidance on signs to check around a possible snake hole before deciding what made it.

Remove shelter and accessible food

Move brush, loose lumber, rock piles, and debris away from the building. Keep firewood raised off the ground and separated from the wall. Cut back tall grass where it conceals foundation openings.

Secure birdseed and grain, clean up spilled pet food, and manage refuse and compost. Address rodent or insect activity rather than treating the snake as an isolated visitor. In multifamily buildings, include shared storage and attached spaces in the inspection.

Removing the snake addresses the visitor. Correcting access and prey conditions addresses the property.

Trapping alone doesn't solve the problem if access points remain open. New animals can enter through the same route. Commercial repellents shouldn't replace building repairs, and a clean-looking room shouldn't end the search for hidden access.

How to Seal Entry Points Once the Snake Is Gone

Confirm the snake is out before sealing anything. An empty-looking room isn't enough when the animal disappeared into a connected void. Have the unresolved location assessed before closing its possible exit.

Mississippi State University Extension's home snake-exclusion guidance recommends inspecting the entire foundation and addressing openings approximately 1/4 inch (6 mm) or larger, using materials suited to the structure. Use that guidance for the size-based repairs below.

Each gap you find is also evidence. An opening that fits a snake is the route it used, so treat the repair list as a map of how the animal entered, not a generic weatherproofing job.

Work around the whole building

1. Confirm removal or departure. Resolve uncertainty about hidden spaces before starting permanent repairs.
2. Walk the full perimeter. Include basement doors, window wells, crawl-space vents, utility penetrations, porch edges, and sump or drain openings.
3. Mark gaps for repair. Record the location and construction material so you can select a lasting closure.
4. Match the repair to the opening. Use the table below rather than applying the same filler everywhere.
5. Address below-grade access. Continue appropriate barriers beneath accessible edges, while accounting for drainage and the structure.
6. Inspect at dusk with a flashlight. Pay attention to threshold corners, loose screens, and incomplete joints.

Gap size and the right sealing material

The 1/4-inch threshold in this table follows the extension guidance linked above. The buried-edge depth is a field recommendation from exclusion work, and soil conditions on your property may call for adjusting it.

Use the material specifications above when planning repairs. Screen ventilation openings; don't fill them solid. Guidance on how to screen a vent properly can help distinguish screening work from general gap filling.

The common failures are incomplete inspections and unsuitable materials. A neatly patched opening won't compensate for another accessible gap nearby. Weak filler also isn't a durable answer where rodents can reopen the route.

For properties with venomous species, the Colorado State guidance cited earlier also describes specialized perimeter fencing. That's a site-specific option, and the building repairs above still come first.

Verify each repair before calling the job done. Photograph every marked gap from a fixed angle on the day you seal it, then retake the same shot a week later. A reopened seam, a sagging sweep, or disturbed soil beside a buried edge will show up in the comparison faster than it would from memory alone.

Confirm the Snake Is Gone and Track Repeat Signs

Memory fades faster than evidence does. A dated log turns a vague sense that "the snake is back" into something you can act on: where it appeared, what changed, and whether the same route is still open. Write each observation down the day it happens.

Record what changes

• Location and timing. Note the room, nearby opening, date, and time of each observation.
• New evidence. Photograph suspected shed skin, droppings, gnawing, or displaced screening without disturbing it.
• Repair condition. Record loose door sweeps, damaged mesh, and gaps that have reopened.
• Response taken. Note who inspected the area and which repairs were completed.

Read the log as a diagnostic tool. A second sighting near the same gap tells you the route is still open. One near a different wall, paired with fresh gnawing or droppings, points to prey drawing snakes back toward the building. The pattern in your notes tells you which problem to fix first.

No new sightings is encouraging. It is not proof that every route is closed.

If another snake appears or fresh signs keep showing up, the same conditions that called for a professional the first time still apply. Traps alone will not solve it, because new animals move in while access points stay open.
