10 Fascinating cockroach facts that will surprise you
A cockroach can hold its breath for up to 40 minutes—so think twice before trying to flush one down the drain. Known for their resilience and adaptability, cockroaches are one of the most difficult pests to eliminate without expert help. Here are ten fascinating facts about them:
1. They can live without their head
Cockroaches breathe through tiny holes in each body segment and have an open circulatory system. This means they don’t rely on their mouth or head to breathe. In fact, a cockroach can live for up to a week without its head—it dies only because it can no longer drink water.
2. They can hold their breath for 40 minutes
Cockroaches regulate water loss by holding their breath, and can even survive being submerged in water for up to 30 minutes. This makes them difficult to drown or eliminate using simple household methods.
3. They spread germs quickly
With the ability to run up to three miles in an hour, cockroaches can rapidly spread bacteria and germs throughout a home or business, posing serious health risks.
4. German cockroaches mature fast
German cockroaches, one of the most common species in the UAE, can grow from hatchling to adult in just 36 days. They are also associated with allergic reactions and disease outbreaks.
5. Baby roaches are fast, too
A newborn cockroach, barely visible to the naked eye, can run nearly as fast as an adult, making infestations challenging to detect early on.
6. Some are attracted to beer
The American cockroach has been shown to favour alcoholic beverages—particularly beer—due to its sugar and hop content. This is especially relevant in hospitality environments.
7. Some cockroaches are giant
The largest known cockroach, found in South America, grows up to six inches long with a one-foot wingspan. Thankfully, most species found in the UAE range from ½ inch to 2 inches.
8. They’re ancient survivors
Cockroaches have been on Earth for more than 280 million years, making them one of the oldest insect species in existence.
9. There are over 4,000 species worldwide
Globally, there are more than 4,000 cockroach species. The most commonly found in UAE households and businesses are the German, brownbanded, and American cockroach.
10. They can live a month without food
Cockroaches are cold-blooded and can survive for up to a month without food. However, they can only survive a week without access to water—making leaky pipes and damp spaces ideal hiding spots.
Why professional pest control matters
Cockroaches are remarkably resilient and capable of thriving in the most difficult conditions. Their ability to hide, multiply, and carry harmful bacteria seriously threatens hygiene and safety in residential and commercial spaces.
