Wildlife danger during a house sit is genuinely rare, most sits happen inside towns and cities, and most animals actively avoid people. But rare isn't the same as never, and we've had real, close encounters with some of Australia's most dangerous snakes and spiders. Here's what we've actually learned, an honest account of where our own knowledge stops, and what to actually watch for across the regions this site covers.

Our Real Encounters in Australia
I've never been bitten, and nothing dangerous has actually happened to us during an actual house sit, across any of our Australian sits. But growing up and working there gave me several genuinely close calls worth being honest about.
At my mum's place, an eastern brown snake crossing the front porch is simply a normal occurrence, not an emergency. Eastern browns carry the second most toxic venom of any land snake in the world, and they're responsible for more snakebite deaths in Australia than any other species, not because they're the single most venomous, but because they're common in exactly the populated, farm-adjacent areas people actually live in.
While doing some gardening at a property, I almost picked up a red-bellied black snake without realising it. Red-bellied blacks are actually less venomous than many other Australian snakes and rarely fatal, though a bite still causes real, significant illness and needs proper medical attention. They're also generally non-aggressive and retreat from people, which is exactly why an accidental, close encounter like that one is more common than an actual attack.
The closest call was during my time as an outdoor instructor. I sat down in the bush, and when I stood back up, found a Sydney funnel-web spider dead beneath where I'd been sitting, facing downward, which meant its fangs had gone into the ground rather than me. Funnel-webs are widely regarded as the world's most dangerous spider by reputation, though there hasn't been a recorded death since antivenom was developed in 1981. I've also stepped on a brown snake while walking through the bush, and seen reports of large snakes in beach dunes on walks along the coast. None of this is dramatic or common. It's simply what living and working in certain parts of Australia occasionally involves.
Australia: What to Actually Watch For
| Animal | Where | Real risk level |
|---|---|---|
| Eastern brown snake | Widespread, including populated eastern suburbs and farms | Second most toxic land snake venom in the world, responsible for the most snakebite deaths in Australia due to how common it is near people |
| Red-bellied black snake | East coast, including Sydney region | Less venomous than many Australian snakes, non-aggressive, no recorded deaths, but a bite still needs medical treatment |
| Sydney funnel-web spider | Sydney region, often in pool filters or shoes left outside | Widely considered the world's most dangerous spider by reputation, no deaths since antivenom was developed in 1981 |
| Paralysis ticks | East coast, a genuine risk specifically for dogs | Can be fatal to pets if untreated, worth asking homeowners about directly on any dog-involved sit |
| Saltwater crocodiles | Northern Australia | Most visible basking on shorelines during cooler months, less visible in summer when water is warm enough to stay submerged |
North America: What to Actually Watch For
We haven't sat anywhere in the US with genuine wildlife exposure ourselves, our city guides so far have covered Chicago, Seattle, and Austin, all urban settings. This table reflects research rather than direct experience, and it's worth treating it that way.
| Animal | Where | Real risk level |
|---|---|---|
| Rattlesnakes | Widespread across most US states, especially warm-weather states like Florida and Texas | Responsible for most fatal snakebites in the US, though fatalities remain rare with treatment, roughly 7,000-8,000 bites a year, about 5 deaths |
| Copperheads | Eastern US | Cause more snakebite incidents than any other US species, though bites are rarely fatal |
| Black bears | Widespread forested regions across the US and Canada | Generally avoid people and tend to flee, far less dangerous than grizzlies as a rule |
| Grizzly bears | Alaska, Montana, Wyoming, Idaho | Genuinely dangerous and unpredictable, responsible for most bear-related fatalities in North America since 2000 |
| Mountain lions (cougars) | Western US, parts of Canada | Generally avoid humans, but documented attacks exist, over 130 in North America across the past century |
| Black widow spiders | Widespread, often in garages, woodpiles, dark corners | Venomous and can cause serious illness, but defensive only, they don't seek out people |
Europe: What to Actually Watch For
This is the region we've spent the most time in through our European sits, and driving through the Balkans specifically brought this into focus. We visited a bear sanctuary in Kosovo while driving through the region, which made clear that bears are genuinely present there, even though we never encountered one directly ourselves.
| Animal | Where | Real risk level |
|---|---|---|
| Common European adder | Widespread across Europe, the most common venomous snake on the continent | Responsible for more bites than any other European species, generally non-aggressive, rarely fatal with treatment |
| Nose-horned (horned) viper | Balkans, Italy, Austria, dry rocky hillsides | Widely considered Europe's most dangerous snake, potent venom and long fangs, though shy and rarely encountered |
| Asp viper | Southwestern Europe, including France, Spain, Switzerland, Italy | Considered the most dangerous snake in that specific region, a genuine medical emergency if bitten |
| Brown bears | Scandinavia, the Balkans, Romania, Italy, Iberia | Roughly 17,000 across Europe, generally avoid people unless directly threatened or surprised at close range |
| Ticks (including the castor bean tick) | Widespread, especially wooded areas | Can transmit Lyme disease, tick-borne encephalitis, and Q fever, a genuinely relevant everyday risk, more so than any of the larger animals above |

Being Honest About What We Don't Know
We have no direct experience with bears, mountain lions, or leopards, and we're not going to pretend otherwise. What we do have is a genuine awareness that this risk exists in parts of the world we haven't lived in ourselves.
If a sit is in bear, mountain lion, or leopard territory, the right move is the same principle that applies everywhere: ask the homeowner directly what the actual local risk looks like, and what they'd want you to do. That might include carrying bear spray on walks, keeping a dog properly restrained in known wildlife corridors, and generally staying alert rather than assuming a quiet trail is automatically safe.
People who get seriously hurt by wildlife like this are, in most documented cases, careless in some identifiable way, surprising an animal, cornering it, or ignoring a known local warning. Preparation genuinely does reduce the risk, even though it can't eliminate it entirely.
The One Thing That Actually Protects You
Ask the homeowner directly, before or as early as possible during the sit, what wildlife is genuinely relevant in their specific area, and what they'd want you to do about it. This is exactly the kind of detail worth raising on the pre-sit video call, alongside anything else specific to the property. Homeowners living somewhere with real wildlife risk already know the practical answers, when to worry, when not to, what precautions actually matter locally, and passing that knowledge on takes them a few minutes.
It's also worth remembering that most wildlife is more afraid of you than the reverse, and will retreat the moment it senses a person nearby, provided it isn't cornered or surprised at close range. Animals venturing into populated areas at all is almost always about seeking food, not seeking confrontation. Staying aware of your surroundings, particularly walking a dog through known wildlife corridors, matters more than any specific gear or product.
Conclusion
Genuine wildlife danger during a house sit is rare, most sits happen inside towns, and most animals want nothing to do with people. But rare doesn't mean it never happens, and being honest about it, what we've actually encountered, and what we genuinely haven't, matters more than pretending to have universal expertise. Ask the homeowner directly, take local advice seriously, and treat quiet trails and unfamiliar gardens with the same awareness you'd want a sitter to have looking after your own home.
Caro and I have completed 20 house sits across 12 countries, driven 19,000km across Europe in our 1998 VW T4, and saved over $26,500 in accommodation costs over three years of house sitting.

Frequently Asked Questions
How dangerous is wildlife actually during a house sit?
Genuinely rare in practice. Most sits happen within towns and populated areas, and most wildlife actively avoids people. Real risk exists in specific regions, but it's the exception, not the norm.
What should I ask a homeowner about local wildlife before a sit?
Ask directly what's genuinely relevant in their specific area, venomous snakes or spiders, ticks, crocodiles, sharks, or larger predators depending on the region, and what precautions they'd actually recommend. Homeowners living there already know the practical answers.
Are Australian snakes and spiders as dangerous as their reputation suggests?
Some genuinely are, eastern brown snakes carry the second most toxic venom of any land snake in the world, and Sydney funnel-web spiders are widely considered the world's most dangerous spider. That said, fatalities are rare thanks to antivenom, and most of these animals avoid people rather than seek confrontation.
What should I do if I'm sitting somewhere with bears or large predators?
Ask the homeowner directly what local precautions they'd recommend, which may include carrying bear spray, keeping a dog properly restrained in known wildlife areas, and staying genuinely alert on walks rather than assuming a trail is automatically safe.
Why would wildlife become a real danger near a house sit?
Almost always food-seeking behaviour near populated areas, or a person accidentally surprising or cornering an animal at close range. Most wildlife wants distance from people, not confrontation.
