If you’re starting to observe an unusual smell lingering around the house, it’s easy to suspect that there’s a roach infestation. Cockroaches are one of the most common pest infestations that produce a strange smell when there is a large number of them. A cockroach infestation smell is hard to describe but it’s an obvious sign of a cockroach infestation.
When you begin to notice a strange smell that doesn’t go away even after you’ve cleaned the entire house, you must start investigating where the smell comes from. Look for signs of a cockroach infestation and get rid of it right away before it gets worse. Remember, cockroaches and disease go hand in hand.
WHAT ARE THE SYMPTOMS OF A COCKROACH INFESTATION?
There are subtle signs and not so subtle signs of a cockroach infestation. You must know what these symptoms are to quickly trace where it’s coming from. It’s easier to get rid of the infestation once you’ve contained the source and magnitude of the infestation.
Here are the more noticeable symptoms of a cockroach infestation:
1. ODOR. A cockroach’s smell is difficult to describe but it’s very noticeable. A lot of people brush the smell as something to do with putrid moisture escaping from cupboard crooks or damp corners of the house. It’s perhaps because the smell of a cockroach infestation is hard to describe and can be inadvertently attributed to other smells.
However, once you begin to smell something unpleasant that is kind of musty and sweet but at the same time offensive, this is not something you can dismiss as any other smell. Trace the smell from under the sink, inside cupboards, kitchen corners, crawl spaces, or any moist places in your house.
2. SOUND. Contrary to what everyone believes, cockroaches do make a sound. The moment they start running around your kitchen past bedtime, you can pretty much observe the sound of their legs hitting the wood, granite, linoleum, or porcelain.
3. DROPPING. Cockroaches leave tiny crumbs much like Hansel and Gretel in a form of small black droppings. You can pretty much confuse these as ground black pepper. When you see these things scattered inside your storage areas, food cabinets, or near pet food, then that’s a sure sign of cockroaches feasting while you’re asleep.
4. EGG. Another clear sign of a pest infestation is the presence of cockroach eggs or what’s called ‘oothecae’ sacks. These egg cases hold an average of 16 cockroach eggs, and they’re very visible; littered or stuck inside dark and humid areas of the house as well as on major appliances, shelves, or bookcases.
On the other hand, when you start seeing cockroaches frequent around the house, slipping through every narrow corner or peeking through tiny openings, you must accept the fact that your house has been completely infested. It’s time to eliminate them before the cockroaches start infecting your household with diseases.
WHAT EXACTLY DOES A COCKROACH INFESTATION SMELL LIKE?
One of the most obvious signs of a cockroach infestation is the smell. Just how do you determine whether a particular smell is a sign of a cockroach infestation or simply just a rotten vegetable? Unfortunately, it’s a little hard to explain. The smell of a cockroach infestation is difficult to compare to. And, there’s not a single word that describes exactly what a cockroach’s smell like.
However, there’s a science to a cockroach’s smell. A collective pheromone found in the cockroach’s feces produces a distinct smell that can be sweet, heavy, and musky. On top of that, a chemical called cuticular hydrocarbon is used by cockroaches to communicate with each other. This chemical is found wrapped around a cockroach’s body—the legs, antennae, body, skin. This is pretty much what’s giving a cockroach its distinct smell.
Consequently, when cockroaches die, fatty acids called oleic acid, produce a putrid smell as dead cockroaches decompose. This smell is repulsive even for other cockroaches and insects making them move away from it.
Ultimately, scientific or not, you can observe a cockroach smell. The intensity of the smell will tell you whether the infestation is getting worse. The strangely sweet, musky, heavy, musty, pungent, oily, and offensive smell that increases in intensity as the infestation grows is a clear sign of a cockroach infestation. Your best option is to contact a pest management professional when you notice that the symptoms have become large-scale.

- Oriental cockroach – these are smaller cockroaches that measure up to 25 millimetres long and are dark brown or black. Their wings are smaller and underdeveloped. These cockroaches can adapt to the natural environment and prefer to feed on decay, garbage, litters, and/or landfills.
