My SIL had a cobra get into her house shortly after they put a new highway in close by. I had no idea they were here. If I had seen that, I would have likely burned the house down.
Don't worry Hawk- you are far more likely to die on the new highway

10 times more likely.
Statistics doing their thing there.
There are several very venomous snakes in Indonesia, & we see a few species in our garden.
Namely:
Banded krait /
Bungarus candidus - these are shy and active at night- contrary to popular belief they do not break in to houses to jump in bed and bite people, they have got into unsecured houses and have snugged up in a warm place (a bed on the floor?) and the person rolled over on it- it bites only in defence)
Coral snake/ ular cabai /
Calliophis intestinalis- super toxic and deadly- also beautiful and very shy, the kids here grab them and walk round with them - we wonder why people die from snake bites,this is a perfect example.
Red necked keelback/ ular kepala merah/ Rhabdophis subminiatus- which has just been updated to the venomous category; it is an interesting snake because it secretes the toxins it gets from eating frogs behind its head as a poisonous defence as well as having a venomous bite. I have lots of pics of this and some of my hubby handling it before it got a classification change they hang out in the garden and the steam/ditch outside.
I want to make note that pre my coming to Indonesia I was phobic as all hell about snakes.
Then I lived here and that was a dumb phobia for me to have so I made sure I worked on it..
I learned about each and every species we have here, there are really interesting snakes.
I saw enough of them in the garden that I had to learn management- a long handled broom is perfectly good enough to gently sweep and encourage a snake away. A wet mop is a good way to pin a snake in place whist you go grab a broom- done both haha.
No need to hit or hurt the animal, a snake will happily bugger off rapidly away from a human 99.999% of the time.
I used the broom when the snake was between me and the dog & I wanted to protect the dog and the snake from getting bitten. I wasn't randomly chasing a snake round the garden with a broom- though that does conjour up a cartoon-like meme in my head.
At night if you are going to step outside, ensure lights are on- so you can see where you are about to step- many bites happen just from accidentally stepping on a snake. I speak from experience- I opened the door one night to let the dog out and she jumped outside, I was about to follow and saw the krait right on the doorstep- that then became a broom/wet mop-job as I did not want the dog to see the snake. So now, I keep the dog behind me when I open doors and I check for snakes first- simple step once learned the hard way never forgotten!
Back to statistics and facts:
A snake may well not always waste all their precious venom on a bite on you /humans -they do not see you as prey.
Sometimes they dry bite- hence the fact that in Indonesia there are only on average about 35 deaths a year from venomous snake bites- in a population of 280 million that is tiny.
Try to think of them as dog bite equivalents in the USA- 35- 50 people die each year from dog bites, yet hundreds of thousands get bitten.
@Wisnu The mother snake will be long gone, they do not hang around to rear their young- they just hatch them. All it means is that a nest was nearby weeks ago. The young hatch and are fully independent.
Hunting and killing local wildlife is not really a good thing to do, at best you are just putting yourself in range of a bite if anything. No matter how you try to justify it.
I would strongly advise this:
Use common sense and also learn about the animals, use sensible precautions and then you do not need to go around murdering animals that are in their own environment that humans have encroached on.
It just makes me so sad and disturbed that some people turn to auto-kill like it is some sort of accepatable thing.
Worried about kids in the area, educate them about the snakes.
See one? Walk away.
One in the house? Open the door and do not get between it and the door- it will seek a swift exit. If a snake has an escape route it will take it- for the most part... call in a snake catcher if you need to.
Pit vipers are probably the exception to the rule as they like to sit still and wait for prey to come to them. So look where you put your feet when out walking.
Don't leave doors wide open if you are not prepared for critters coming in.
Snakes follow the scent of rats and mice as their main prey... try to keep the rodents out of the house- a battle I think I have won at my house ... until the next time they come in.
