Snakes inside the house: how they get in and how to prevent it

Snakes inside the house are usually seen when they find gaps, poorly sealed doors, open windows, overgrown gardens, or signs of rodents. Specialist warnings do not mean these animals are “hunting people”; rather, they may move closer to homes in search of shelter, water, warmth, or food. Prevention starts with sealing the property properly and keeping the surrounding outdoor area under control.

Why can snakes get into homes unnoticed?

Because their bodies are highly flexible, snakes can slip through much smaller openings than most people expect. Spaces under doors, gaps in gates, uncovered drains, low windows, and holes near boundary walls can all become entry routes-especially in single-storey homes and properties next to vacant plots.

During spells of heat, drought, heavy rain, or flooding, they may relocate to find safer ground. Garages, utility rooms, storage areas, external passageways, and places where boxes are stacked up can provide shade and a temporary hiding place. That is why taking care to shut doors and windows properly is a practical home-safety step.

How should doors and windows be protected?

Closing doors and windows “firmly” should not be taken to mean slamming them, but ensuring they sit correctly in the frame, with no open gaps and no loose latches. A door that is merely pulled to can leave enough space for small animals to get through-particularly at night.

• Fit door sweeps or draught excluders along the bottom of external doors.
• Install mesh screens on low windows, top-hung windows, and ventilation openings.
• Shut gates and garage doors at dusk.
• Cover outdoor drains with well-fitted grilles.
• Seal cracks and gaps around walls, skirting boards, thresholds, and masonry.

Checks should focus on parts of the home that are used less often. Box rooms, outdoor utility areas, and spaces behind furniture can collect clutter and conceal openings that go unnoticed in day-to-day life.

What in the garden attracts snakes closer to the home?

The garden is your first protective barrier. When there is rubble, dry leaves, stacked timber, organic waste, and long grass, the space becomes attractive to rodents, insects, and other small animals. As some snakes feed on these prey animals, the property can become indirectly more appealing.

Keeping outdoor areas tidy removes hiding spots and makes it harder for snakes to approach. This needs to be done routinely, because even one stack of tiles, boxes, or branches near a wall can become shelter. On larger plots, looking after the edges along fences and walls matters just as much as the centre of the garden.

• Cut the grass and clear vegetation growing right up against walls.
• Avoid piling up rubble, bricks, tiles, and leftover building materials.
• Store pet food in sealed containers.
• Keep bins closed so they do not attract rodents.
• Move wood piles away from doors and windows.

What should you do if you find a snake inside the house?

If you come across a snake, the first rule is to keep your distance. Do not try to touch it, kill it, trap it, or identify the species yourself. Even snakes that look small or motionless can strike if they feel cornered. Move children and pets away straight away.

If you can do so without going near the animal, shut the room door to limit where it can go. Then contact the Fire and Rescue Service or your local council’s animal control/public health team (where available). Trying to deal with it alone increases the risk of injury, especially in confined spaces, around furniture, or in poor light.

Prevention is safer than improvisation

The most effective way to avoid snakes inside the house is to combine good sealing, regular outdoor maintenance, and reducing food sources for rodents. Properly fitted doors, screened windows, protected drains, and a well-kept garden make the home harder to access-and less attractive to animals seeking shelter.

If a snake is already indoors, priorities change: nobody should turn it into a DIY capture attempt. Keeping people and pets back, maintaining a safe distance, and calling trained help is the safest way to protect the household without putting residents, neighbours, or the animal at risk.
