Other species, such as the widespread
Sometimes when they're threatened, they'll fly to escape– either from a predator or from a human who wants to kill them. If they take off and fly straight towards you, they're usually just frightened and not in very good control of where they're headed.
Cockroaches will mostly likely fly if they feel there is a threat and they need to get away quickly. They also might use their wings like gliders if they happen to be in a high place and need to get down to a lower place. This allows them to get down more easily than by falling.
Cockroaches are not likely to bite living humans, except perhaps in cases of extreme infestations where cockroach population are large, especially when food becomes limited. In most situations, cockroaches would not bite humans if there are other food sources such as in garbage cans or exposed food.
Cockroach Urine
Just like with their droppings, cockroaches will urinate anywhere, and their urine also contains harmful diseases. If you have a large infestation on your hands then there might be a chance that a lot of items might be contaminated with cockroach urine in your property.
Cockroaches do sleep and just like other animals and insects, they also follow a specific circadian rhythm. They are nocturnal insects, which means that they rest or sleep during the day. Cockroaches are usually active for four hours after dark and then go into a period of immobility.
Females have vestigial wings, and males have short wings that are not as long as their bodies. Neither male nor female can fly. Oriental roaches like cool, damp places and prefer the dark.
Cockroach Droppings Appearance
Cockroach feces are easy to identify. Droppings from small cockroaches resemble ground coffee or black pepper. Larger roaches leave behind dark, cylindrical droppings with blunt ends and ridges down the side.
Not only do they help “clean up” degrading plant material, in the process their bodies trap a lot of atmospheric nitrogen. Basically, the purpose of cockroaches in this case is basically for cleaning. Cockroaches then release the trapped nitrogen into the soil (through their feces).
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.
The secret is in their legs. All six legs have three knees, 18 knees altogether. With so many joints, their movement has precision and accuracy, with very little wasted movement that could slow them down. Once they get up to speed, they rise on their hind legs and run as humans do, which helps them run even faster.
They also tend to have emotions. Also, when insects, just like most animals, feel that they are being threatened, they tend to protect themselves. Thus, they seem like they are trying to take revenge on you.
"Cockroach feeding has the effect of releasing that nitrogen (in their feces) which then gets into the soil and is used by plants. In other words, extinction of cockroaches would have a big impact on forest health and therefore indirectly on all the species that live there."
Roach droppings look like specks of pepper, coffee grounds, or dark grains of rice. The size of the feces is directly related to the size of the cockroach. Bigger insects produce larger droppings.
What's Inside Cockroach Droppings
And dead insects, including the carcasses of other cockroaches. Cockroaches don't pee (a not-so fun fact), but instead secrete solid and semi-solid waste. All of which varies in appearance, depending on the size, age, and species of roach you're dealing with.
They're mesopredators, more than willing to hunt down and kill these resilient pests. However, cats aren't the best at preventing cockroach infestations. Even though cockroaches are high in protein, they aren't a good food source for cats due to their tough exoskeletons cockroaches.
Raid Ant & Roach Killer Insecticide Spray was found to be one of the most effective at killing cockroaches. A can is helpful for the times when you spot a roach in your home and you don't want to get too close. A roach spray should kill the bug almost instantly.
Cockroaches don't technically get pregnant because most species (see above) don't give birth to live young. But when they do get “pregnant”, they form the egg sac that will hold their eggs until they hatch. Some species only mate once; they'll keep reproducing from that first mating for the rest of their lives.
Do Cockroaches Like the Cold? Generally, cockroaches don't like the cold one bit. They are cold-blooded arthropods that don't survive very well in either extremely cold or hot circumstances. They're always at whatever temperature their environment is and generally slow down with cooler temperatures.
Cockroaches do not have red blood because they do not use hemoglobin to carry oxygen. They do not carry oxygen in their blood stream either. Most cockroach's blood is colorless.
Cockroach Bites Are Powerful
You may not feel them when biting you, but the aftermath might give you a painful sensation. Cockroaches' bite force is 50 times powerful than their body weight. The pain might depend on your tolerance, but if you have low pain tolerance, then you might find it too excruciating.
Maxillae - basically the teeth of the roach. These are secondary chewing parts that further grind down the food into smaller and smaller pieces so they can be pulled into the digestive areas for nutritional purposes.
It's a fact that cockroaches are afraid of humans and other mammals or animals that are bigger than them. They see us as predators and that fear triggers their instinct to scatter away. However, they dislike strong and distinctive scents such as citrus, peppermint, lavender and vinegar.
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.
