Expect roaches, rats, bedbugs, and other diminutive neighbors. They'll put you up in anything from the tire shop out back to the master bedroom. I always carry a hammock with me so that I cause minimal disruption. The toilet may be the river's edge and the river may be the shower - and the place to wash vegetables. Everyone will be friendly and everyone will stare at you all the time.
Rats love sugarcane and rats are nocturnal - and curious.
It's very unlikely that you'll step on one that the entire population has missed for the last twenty years, but I'd hate to be wrong about that.
