What are cockroaches?

Cockroaches are the most common insects, numbering more than 5 thousand species of different roaches. Their ability to adapt to any situation allows them to survive under the most inappropriate conditions. Scientists suggest that roaches can survive even a nuclear explosion. This fact makes them invulnerable and leaves us so little chance to get rid of roaches.

Roaches differ in size, color, and types of nutrition. Red cockroaches are the most common species, living near humans. Their body is flat, oval, measuring from 4 mm to 1,5 cm.

Interesting facts: Madagascar hissing cockroaches reach 6-8 cm in length. And 16 species of these insects from the Seychelles archipelago are included in the Red Book and are protected by the state.


Cockroaches prefer warm and humid places. They are nocturnal insects. Roaches hide in secluded places during the day. Therefore, you can detect them at night. If you turn on the light, you will see roaches running through the cracks. Cockroaches are very mobile insects. They run fast and sometimes you cannot swat them.

Roaches reproduce by laying eggs. One egg case contains from 15 to 50 individuals. One female may create at least 10 egg cases in her lifetime. It takes 4 months for a cockroach to develop from an egg to an adult. Roaches can live and reproduce up to 30 weeks. During this time, more than 300 individuals can produce offspring. A female carries eggs in a bag at the back. This egg is called an ootheca. It is often taken for an elongated tail. In case of danger, a dying female can throw back, i.e. catapult, her egg case, and the eggs with roaches will remain alive. Such situations may occur, when a cockroach female runs away and throws back her egg case. In case of exposure to poisonous substances, the eggs remain alive and a young generation of roaches develops from them.

These characteristics of cockroaches indicate their fast reproduction and strong survival ability. The roach infestation of any house is possible due to their high reproduction and survival abilities.

Features that affect the survivability of cockroaches:

  • A cockroach can live for a week without its head.
  • They spend ¾ of their life at rest.
  • Cockroaches run at a speed of 4,8 km/h. This is very fast, considering their small size and short legs.
  • Roaches can hold their breath for 40 minutes.
  • They can eat once a month (besides, they can eat anything).
  • It is difficult to catch a cockroach – it feels the approach of the enemy with the hairs on its legs and changes the direction of movement 25 times per second.
  • The theory that cockroaches will survive a nuclear explosion is scientifically confirmed: they have a slow cycle of cell division, and radiation is not dangerous for them. They can withstand radiation, which increases the human lethal dose 16 times.
  • Roaches have 2 pairs of wings: the upper leathery elytra protect the body, and the thin wings under them allow cockroaches to fly.
  • Red cockroaches are the leaders among all the others: they are the first to start multiplying. They are more careful about their offspring and can destroy the ovipositors of other species.

What harm do roaches cause?

In addition to their unpleasant, frightening and hideous appearance, cockroaches cause tangible harm in the house. So that the question how to get rid of roaches becomes vital.

Roaches damage products, plants, leather goods, and book bindings. They leave their feces in cabinets, doors, and secluded places, where they hide during the day.

In addition, cockroaches can transmit up to 50 species of bacteria, infectious diseases, typhoid fever, dysentery, poliomyelitis, gastroenteritis and intestinal worm eggs. Running about garbage cans, basements, and excrements, they catch infections to their legs. And then roaches can meet your products and dishes.

During molting, cockroaches remove their chitinous scales, which, combined with dust, may lead to allergies and asthma.
