7 Things You Didn’t Know About Cockroaches

Cockroaches are among the most reviled pests we know — yet they are also some of the most fascinating. Their resilience and ability to survive extreme conditions make them a subject that both repels and captivates. Here are seven surprising facts about cockroaches you probably didn’t know.

#1: They can survive without a head for several days

Cockroaches have such a simple circulatory system that they don’t require their head to survive initially. They breathe through small holes in their bodies, allowing them to continue living – and even walking around – for up to a week without a head. They eventually die from dehydration.

#2: Cockroaches can hold their breath for 40 minutes

As incredible as it sounds, cockroaches can close their spiracles and hold their breath for up to 40 minutes. This not only helps them avoid drowning but also aids in regulating their water loss in dry conditions.

#3: They are true survival experts

Cockroaches have existed for over 300 million years – long before the dinosaurs. Their ability to adapt to new environments and survive in extreme conditions makes them one of nature’s most resilient species.

#4: They can survive microwaves

It is a persistent myth that cockroaches are immune to microwaves – but the truth is that they often avoid dying in a microwave because they can find shelter in corners where the microwaves don’t effectively reach.

#5: They can run up to 3 mph

For their size, cockroaches are extremely swift. They can travel at speeds up to 3 miles per hour, which assists them in rapidly escaping danger – making them extra hard to catch.

#6: There are over 4,000 species

Although we often only hear about the few species that infest our homes, there are actually more than 4,000 different varieties of cockroaches worldwide. Most live in the wild and are completely harmless to humans.

#7: They can survive nuclear disasters

Cockroaches are famously believed to survive nuclear disasters — and while that’s an exaggeration, it’s not entirely untrue. They can withstand much higher levels of radiation than humans, which has earned them a reputation for being nearly indestructible.
