18 Fun Facts About Cockroaches (Creepy, Crunchy and Surprisingly Tough)
Cockroaches are survivors. They outlasted the dinosaurs, they outlast most diets, and they can outlast your patience. Here’s why they’re so hard to get rid of.
Quick answer: A cockroach can live about a week without its head, hold its breath for around 40 minutes, and roach ancestors have been around for roughly 300 million years. German cockroaches — the most common indoor roach — multiply fast because each egg case holds dozens of babies.
The fun (gross) facts
- They can live about a week without a head. They breathe through holes in their body. They eventually die of thirst.
- They can hold their breath for around 40 minutes. Flushing one doesn’t always work.
- They’re ancient. Roach-like insects go back about 300 million years.
- The nuclear thing is half true. They handle more radiation than people — but they wouldn’t be the last ones standing.
- German cockroaches are the #1 indoor roach. Small, tan, two dark stripes behind the head, kitchens and bathrooms.
- One egg case holds dozens of babies. German roach egg cases hold around 30–40 eggs.
- Mom carries the egg case. German roaches carry it until it’s nearly ready to hatch — protecting it from sprays.
- They’re fast. The big American cockroach can run several feet per second.
- Some fly. American cockroaches can fly or glide, especially when it’s warm. Yes, at your face.
- They love tight spaces. They feel safest when touching surfaces above and below them.
- They can flatten themselves. To squeeze into cracks thinner than you’d think.
- They taste with their feet and other body parts too.
- They eat almost anything. Crumbs, grease, glue, soap, paper, hair.
- They’re mostly nocturnal. Seeing roaches in daytime usually means a big population.
- They trigger allergies and asthma. Roach droppings and shed skins are known indoor allergens.
- “Waterbugs” are usually roaches. See waterbug vs. cockroach.
- They hitchhike. In boxes, grocery bags, used appliances and furniture.
