You might be blaming your sneezing, allergies, or breathing trouble on dust or changing weather. But what if the real culprit is crawling around your kitchen and bathroom—cockroaches? Sounds bizarre, but a recent post by a Bengaluru-based cardiologist has sparked concern over the lesser-known link between cockroach infestations and respiratory issues.

Cockroaches and Your Health: What Most People Miss

In his recent post on X (formerly Twitter), Dr. Krishnamurthy pointed out that cockroaches aren’t just a hygiene problem—they could be a health hazard. He shared a picture listing three major conditions linked to cockroach exposure: asthma, Salmonella, and E. coli.

While many people assume asthma is caused by dust or pollution, it can also be triggered or worsened by cockroach allergens, leading to wheezing, breathlessness, or even chest tightness. And it doesn’t stop there. Cockroaches can also carry Salmonella, which causes severe stomach infections and even typhoid fever, and E. coli, a bacteria known for triggering serious food poisoning.

Which brings us to the next big question: how exactly do these pests make us sick?

How Do Cockroaches Spread Disease

Cockroaches crawl through drains, garbage, and sewage, then move across kitchen counters and food, leaving bacteria behind. Their saliva, droppings, and even body parts also release proteins that float in the air, settle on furniture, and can trigger asthma or allergies when inhaled.

Studies have shown that children and elders living in cockroach-infested homes are more likely to have asthma attacks, even without other triggers like pollen or dust.

Warning Signs to Watch Out For

You don’t always have to see cockroaches to know they’re around. Your body might give you clues first. Unexplained fever, nausea, vomiting, or diarrhea that keeps coming back could be early signs. In some cases, people also report flu-like symptoms, body aches, and fatigue that just don’t go away.

But the biggest red flag is trouble breathing. If you’re wheezing, coughing, or feeling chest tightness—especially indoors—it might be more than just allergies or pollution. It could be a reaction to cockroach allergens in the air.

What Can You Do About It

Start by checking for signs like droppings, egg casings, or a musty smell. Clean up food spills, seal leftovers, and fix any leaks. Try natural repellents like bay leaves, or get a pest control check if symptoms persist.

Also, consider using an air purifier, especially one with a HEPA filter, to trap airborne allergens. And if you’re still having breathing problems, talk to a doctor and mention possible exposure to cockroach allergens; it might help catch a diagnosis that’s been missed.

The Bottom Line

Cockroach infestations are more than just a cleanliness issue—they can have serious health effects, especially if ignored. If you’re struggling with unexplained respiratory or stomach issues, it might be time to check for signs at home. Taking a few preventive steps could protect your family’s health in the long run.
