Believe it or not, your beloved monstera could be the culprit. Overwatered plants in poor-draining soil can develop root rot, which is basically a bacterial party that produces hydrogen sulfide. The smell seeps out of the drainage holes or the soil surface.
Quick fix: Repot the plant with fresh, dry soil and trim any mushy, dark roots. Let it dry out completely before watering again. Your plant will thank you by not assaulting your nostrils. Also check under area rugs and in crawlspaces—wet, stagnant spots can harbor mold or dead animals that produce the same odor.
Yes, sometimes the rotten egg smell means something died in your walls. Mice, birds, or even a squirrel can get stuck in vents or insulation. This odor typically fades after a week or two as the animal dries out, but if you can locate the source, call a pest control pro.
The Scatological Scoop
Let’s get real for a second: sewage and rotten eggs smell very similar. That’s because sewage contains hydrogen sulfide from decomposed organic matter. A sudden whiff near your toilet or in your basement could mean a broken sewage pipe, a cracked wax ring, or a clogged vent stack.
Don’t ignore this. Sewage gas isn’t just stinky—it contains methane and can be explosive. Plus, prolonged exposure can cause headaches, nausea, and eye irritation. Call a plumber immediately if you suspect a sewer line issue. Your wallet will hurt less than your lungs.

Fun fact: In Japan, the smell of rotten eggs is often associated with natural hot springs (onsen), which are rich in sulfur. Tourists pay good money to soak in water that smells like a broken egg fart. Perspective, people.
