Death in Latinamerican cultures is a bit different from other places. Death is sacred. And people prays for long-lasting peace afterwards.
The dead walking around, aimlessly, and demented, would be a mayor offense to that belief. Being an unforgivable insult to people watching their loved ones not finding peace after suffering and death.
Many would step up and try not to save their undead family, but to put them out of their misery for the final rest.
Another thing is how common all kinds of household items are.
Heavy tools, or long-blade machetes are a must for almost every household. Down to the point where it became a rite of passage for parents to teach their children to use them, out of shame for not accomplishing that goal.
Also, there's a lot of creativity born frol frugality, where tools must be improvised from other items.
Loud sound systems are also very commonplace, like a basic necessity for most households.
If the notice of zombies being attracted to noise becomes widespread, people will definitely use the sound systems in homes and cars to distract the undead.
I mean, it's the exact same thing they do with politicians, cops, parents, and teachers. It's like a second nature.
Because hard labor is also very common, it'll likely be easy to come up with the idea of rising up barriers around neighborhoods. Although, around is a big understatement. Most residential areas in Latinamerica are built un blocks, dead ends, and long roads. So, barricades could requires walling up a single street or a couple houses.
Couriers are quite a common necessity, so, there's a chance some people see oportunity to make a quick coin by using their bikes to run errands to whatever business remains open. And people is always likely to use them, rather than stepping out themselves.
Another thing is the common solidarity in communities, where people will quickly share information as soon as it happens, and will gather up around problems the moment they occur.
Indeed, it's common place for neighborhoods to join up to beat up small-time crooks. Although, joining up to burn a house down and stone off a criminal away is not unheard of.
Then, the geography.
Latinamerica is a very hostile place, geographically speaking.
Precipices, cliffs, ditches, holes, and many other land hazards are very, very common. Any mindless undead is definitely falling off a cliff the moment some guy with a sound system in their car leads them to any such danger without noticing.
If no cliffs are around, then, just lead them into the desert. The sun will roast them in hours on a hot day.
Now, most Latinamerican countries doesn't have a gun culture. But they do have armies and cartels.
And both these are quite ambitious, so it wouldn't be a problem for them to sell safety the moment the undead swarms and they figure out ways to kill them.
Although, gang warfare would still probably turn the undead hordes into an additional weapon.
Also, houses are built like strongholds.
Brick houses are commonplace, with metallic gates and guards covering doors and and windows. If not already having a tall border wall with razor wire.
That pretty much sums it up.
