And yet, when the mercury rises, vipers can silently slip into your home—without a sound, and without you even noticing. What’s more alarming? Their favorite hiding place might be right under your nose… or more accurately, right under your sofa.

Heatwaves Are Pushing Snakes Into Our Homes

Reports of snakes turning up indoors are increasing—not explosively, but steadily. The primary culprit? Climate change and a growing trend of extreme heat events.

When outdoor temperatures rise above 32°C (89.6°F), snakes such as the asp viper begin to abandon their usual habitats. The dry, scorching environment becomes inhospitable, forcing them to seek out cooler, more stable environments. And surprisingly often, that sanctuary turns out to be your home.

Once inside, snakes are not just looking to hide—they’re looking to survive. Cool surfaces, shade, and a bit of moisture can be lifesaving for a heat-stressed reptile.

Why Your Couch Could Be a Snake’s Summer Sanctuary

It might sound strange, even unsettling, but your living room sofa can be an ideal refuge for a snake. Here’s why:

• Cool tiled floors underneath maintain lower temperatures.

• Shade, darkness, and stillness offer a sense of security.

• Nearby houseplants, often misted or watered, create a more humid microclimate.

• Open windows, patio doors, or floor-level vents make entry surprisingly easy.

• Most importantly? Sofas are rarely moved or cleaned underneath, creating the perfect undisturbed hideout.

To a human, it’s a cozy place to nap. To a snake, it’s a climate-controlled oasis.

In fact, similar spaces—under beds, behind bookshelves, even inside laundry baskets—can all become unexpected snake shelters during periods of extreme heat.

Subtle Signs You Shouldn’t Ignore

No need to panic, but a few subtle clues can suggest a reptilian visitor may have taken up residence. Keep an eye out for:

• Your pet (especially cats or dogs) obsessively sniffing or staring at a corner or under furniture

• A faint, musky odor that doesn’t have an obvious source

• Finding a shed snake skin—thin, papery, and gray—near baseboards or tucked behind low furniture

• Faint rustling sounds at night, especially when the house is quiet

• Realizing a window, screen door, or floor vent was left open during a heatwave

Individually, these signs may seem minor. But together? They could point to an unwelcome houseguest lying low in your home.

5 Simple Tips to Keep Snakes Out This Summer

The good news is that snake-proofing your home doesn’t require traps or poison. A few smart, proactive steps can dramatically lower the risk of a close encounter:

1. Seal ground-level openings—vents, door gaps, and utility access points—with fine mesh or silicone caulking.

2. Install tight-fitting mosquito screens on windows and doors, and keep them closed during the hottest hours of the day.

3. Trim shrubs and ground cover at least 1 meter (3 feet) from your home to remove “bridges” snakes use to access walls and patios.

4. Clear out clutter near foundations: piles of wood, unused planters, or gardening tools that trap moisture and offer cover.

5. Vacuum and clean underneath furniture like sofas, beds, and bookshelves regularly—especially if they sit near external walls or windows.

Bonus tip: If you use fans to cool your home, position them near entry points. Vibrations and airflow are uncomfortable for many snake species and may discourage entry.

Stay Cool—Stay Aware

You don’t need to turn your home into a fortress to stay safe. But a little awareness and a few small habits can make all the difference.

Think of it this way: a cleaner, well-maintained living space doesn’t just discourage snakes—it also improves your indoor air quality, reduces pests, and makes your home more pleasant overall.

As temperatures continue to rise year after year, being mindful of how wildlife reacts isn’t paranoia—it’s practical.

Stay alert, stay tidy, and you’ll enjoy a summer that’s cooler, calmer, and (hopefully) completely snake-free.
