Cockroach brains are considered primitive, as are most insect brains. Cockroaches are not capable of the same level of thought and consciousness as humans. Still, they are one of the more intelligent insects as they: Can learn.
Cockroach's IQ will up to 340 in a second when they meet danger. But when most people meet cockroach, they are so frightened that their IQ will become less than 5.
June is National Pest Control Month—but instead of reaching for the Raid, why not show a little kindness to a cockroach? A new study by scientists at Queen Mary, University of London has found that cockroaches are social beings who “talk” to one another about food and prefer to dine in groups.
Cockroaches and most insects can feel curiosity, excitement, comfort, fear, anger, and greed. The more complex emotions, like jealousy, empathy, and love, only higher animals can feel.
Myth #3: They can see me coming…
True: Why yes, they can. Cockroaches can see humans, and that is why they tend to run in fear when we are in their line of sight. The eye of the cockroach is like a compound lens, made of over 2,000 mini lenses that are photoreceptors and allow them to see in complete darkness.
Cockroaches are a bit different. These invasive home pests do not like being seen and are instinctively afraid of humans. This makes identifying them difficult.
Why Do Flying Cockroaches Fly Toward You? If you think flying cockroaches are flying right toward you, they actually aren't. Most cockroach species aren't good "flyers," and what you take as them flying toward you is actually just them being startled and gliding uncontrollably in a certain direction.
Let's round up the usual household suspects and see which is the sultan of squalor, the ruler of rubbish – basically, the dirtiest insect around. Bedbugs – Your skin might start to crawl at the very mention of these resilient little insects.
Cockroaches clean themselves after touching a human, but it's not because they find people filthy. You won't see a cockroach frantically trying to clean off a human smell or avoiding us because of some dreaded human bacteria. Instead, they'll clean themselves after contact with any predator.
“Some individuals are afraid of them because they can hide in dark places and crawl out unexpectedly. Others imagine cockroaches invading their homes, nibbling on their leftovers, or possibly spreading diseases. To some people, the smell of cockroaches alone can be nauseating.”
Cockroaches have two brains—one inside their skulls, and a second, more primitive brain that is back near their abdomen. Schweid says “Pheromones, chemical signals of sexual readiness, operate between a male and female cockroach to initiate courtship and copulation.
Cockroaches could very well possess a sense of self, and one that's perhaps not entirely alien to our own.
They found that when they later exposed the cockroaches to the odor alone, they still drooled. Another group of cockroaches was fed the sugar solution without the odor, and exposure to the smell afterwards caused no change in the amount of saliva produced. “Sure, cockroaches can remember and learn,” Mizunami said.
If you touch a cockroach, you risk becoming infected with some serious diseases, including bacteria that cause dysentery. According to the World Health Organization, cockroaches commonly transmit these diseases to humans: Salmonellosis. Typhoid Fever.
Absolutely, and roaches in bed while you sleep is definitely not an ideal situation. Even with a clean sleeping space, roaches may still find their way into the bedroom. So many people wonder how to keep roaches away from bed areas but often are at a loss with how to do so without chemicals and sticky traps.

If you're battling an infestation, you may wonder why cockroaches even exist. They appear to serve no real purpose. Cockroaches recycle decay and waste while promoting the nitrogen cycle. They're a food source for predators and assist the ecosystem in inhospitable places.
As far as entomologists are concerned, insects do not have pain receptors the way vertebrates do. They don't feel 'pain,' but may feel irritation and probably can sense if they are damaged. Even so, they certainly cannot suffer because they don't have emotions.
Are roaches capable of making sounds? Some people say yes, and others say no. Certainly, seeing a cockroach can elicit high-pitched screams from an unsuspecting homeowner late at night. However, the most common species, the American and German roaches, are generally acknowledged to be silent.
Cockroaches are omnivores that eat plants and meat. They have been recorded to eat human flesh of both the living and the dead, although they are more likely to take a bite of fingernails, eyelashes, feet and hands. The bites may cause irritation, lesions and swelling.
The myth that killing a cockroach will spread its eggs isn't true, but killing a cockroach with force can attract more. But that can be used to your advantage if it brings bugs out of hiding to be eliminated.
Can Cockroaches Play Dead? Cockroaches can, indeed, play dead. Many have reported seeing cockroaches stay completely still (sometimes even roll onto their backs) until a human presence or threat has gone away. Once they detect the coast is clear, the cockroach will flip back onto its feet and scuttle away to safety.
It is theorized that the cockroach's intelligence is closely tied to its visual processing unit and the mushroom body of its brain. With it, roaches use their smarts for more basic tasks.
