Do Roaches Come Through Drains

Do Roaches Come Through Drainsの概要と注目ポイントを徹底的にカバーしました。

Roaches are master contortionists. They can flatten their bodies to fit through cracks thinner than a dime. Your drain pipe? That’s a five-star hotel lobby to them. But here’s the kicker: they usually don’t swim up through standing water. They prefer dry paths.

Think about it. When’s the last time you saw a roach casually paddling like a tiny, disgusting Michael Phelps? Never, right? They crawl in through the sides of pipes, around loose fittings, or up from the trap when the water evaporates.

It’s Not the Water; It’s the Dry Route.

Your drain has a P-trap—that curved pipe under the sink. It holds water to block sewer gas (and critters). But if you don’t use that sink for a while, the water evaporates. Now you’ve got an open highway with a “Welcome” mat.

Roaches will also exploit cracks in the pipe or gaps around the drain flange. They’re not divers. They’re hikers looking for a dry, dark path into your kitchen. Exaggeration? Barely. I once found a roach in my coffee maker. It didn’t swim there.
