I don't know where all you guys are living here or living when you are here.
Since you are responding to at least a couple of my statements, I'll attempt to clarify a bit. This may take a little work on my part, but I don't want any misunderstandings. We live full time in Louisville, KY. When we visit our family in the Philippines we stay in the house we built for the family, in Bagong Silang, Caloocan City. This is the general location of the house:

When I first met Gloria in 1999 this is what the property looked like

We decided to help the family by building them a nice house, which would also give us a base of operations when we visit. We put roughly Php1.5M into constructing a 5 BR 3-story residence on that "jungle" property. This is the view looking west from our rooftop:

Even though the area has been built up a lot since 1999, it is still on the edge of a ravine flowing down into a river, which gives wildlife an avenue of approach to the back of the houses along our pathwalk. Neighbors killed a cobra behind our house one year
And the last time we visited (late 2016) one neighbor came out of her house screaming for help because she saw a snake crawling up the wall and disappearing into the ceiling of her home. Sorry, no photographic evidence. Yeah, it's on the edge. Naturally there will be insects of all types. And where there are insects, there will be rats and mice.
And someone with all the bugs and netting? Netting for what? You live in one of those huts? And urine trails across the floors from what? I think they mentioned rodents.
Joe was the one who mentioned "net" (not netting) but he was referring to the internet, not "netting" to catch bugs, mice or fish.
As far as urine trails, wherever there are mice or rats there is the possibility of urine trails left by those little scumbags. For those who don't know, rodent urine can carry lots of bad stuff including Hantavirus Pulmonary Syndrome, Hemorrhagic Fever with Renal Syndrome, Lassa Fever, Leptospirosis, Lymphocytic Chorio-meningitis (LCM), Plague, Rat-Bite Fever, Salmonellosis and Tularemia. Quite a list, isn't it? So we (the family) use sticky pads to trap anything that happens to invade the house and we (the family) keep the house as clean as possible to avoid any contamination. As far as insects, yeah, we see ants (who doesn't) and the occasional roach, which is quickly dispatched, the area cleaned thoroughly and either spray or powder put down to help keep the next guy away. It's a tropical country and critters are everywhere, whether you see them or not.
Not all of us have the where-with-all to live in a condo. Even our house in Kentucky is a modest 4-room home. Hell, our house in Bagong Silang is bigger than our house in the US. But the house in Bagong Silang is not airtight, nor does it have aircon, something I do miss when we visit the PH.
Why, you ask, would we build a house in such a "bad" area? Because that's where the family owned property. We built the house for "them", not for us. It is what it is. I still enjoy our visits there and in spite of the house being in a somewhat austere area, it's still one the the biggest houses in Bagong Silang and it's spotless inside. I love our neighbors and miss sitting on the rooftop snacking on food from the night vendors and sipping cold Red Horse with select neighbors and family members.
Whew! That was a lot of work! I hope it enlightens anyone who had questions about when, where and why
Peace
