Mercaptan gives off a strong sulphur-like smell which can be mistaken for the smell of rotten eggs. It's often this smell that is the early warning of any sort of gas leak and you should take the appropriate measures to ensure the safety of yourself and others around you.
One often not considered source of a “gas-like” smell that can come from your home is bacteria inside of your sink or sewer system. It has a similar smell to the sulfur that is added to gas to give it an odor but is obviously less dangerous.
Carbon monoxide doesn't smell like rotten eggs. Carbon monoxide gas is odorless—it cannot be smelled. Some myths surround ways to detect carbon monoxide, such as identifying the strong scent of rotten eggs. However, never ignore the “rotten egg” smell of natural gas.
A weird smell in a house can come from numerous sources, including appliances, furniture, carpets, fabrics or issues like mold or mildew. Occasionally, odors may be caused by sewer gas, natural gas leaks or animals that have died between walls, in attics or under decks.
This scent will evolve to a cabbage-like smell and then to a strong smell of decay. The smell comes and goes in the beginning, it gets worse for a while then it comes and goes again when the dead rodent is almost decomposed. The middle is the worst part.

A qualified plumber, HVAC technician or remediation company can diagnose the source of the odor and take the necessary steps to eliminate it safely and effectively.
Odor sensors have been extensively used to detect gas leakage and in fields such as healthcare, mobility, and spatial environment control, in which the detection of low-concentration biogas and odor is crucial [3].
Leaks are common in doorways and windows that open to the outdoors, which can lead to dampness and in turn lead to mould. Entrances to the home are therefore a likely to be a source of damp smells, so try to check around the doorway for signs of mould.
Radon gas has no colour, smell or taste and is completely imperceptible to humans, even in high concentrations. Radon occurs naturally in the rocks and soil beneath us, but there is no way of knowing how much is escaping from the ground and entering a building.
Cracked sewer pipes may release gases into your house and cause unpleasant smells. Faulty or old wax seals on toilets can allow sewer gases to leak into your bathroom. Sump pump issues can cause standing water, often associated with sewage smells.
