Cockroaches do not suck blood.

But cockroaches can spread viruses.

What are the direct hazards of cockroaches to humans?

The direct harm of cockroaches to humans: first, health hazards; The second is property hazards.

1. Health hazards.

Cockroaches have the habit of eating, spitting and excreting at the same time, and secrete odorous liquid, in their activities, not only can carry more than 40 kinds of pathogens such as Mycobacterium leprae, Yersinia pestis, Shigella dysentery bacillus, etc., but also an important vector of intestinal diseases and parasitic diseases, and its secretions and feces contain a variety of carcinogens.

Cockroaches often hide in dark corners such as kitchens, pantry, feed stores, and bathrooms. It not only harms stored items such as grain, oil, food, clothing and books, but also spreads diseases and causes harm to people.

2. Property hazards.

Factory products, store goods, and home food can all be defaced by cockroach bites, causing economic losses. Cockroaches can also easily drill into large appliances, electronic computers, meters, and household appliances to bite and break lines, or create short circuits, causing unexpected failures.

Nowadays, more and more families, the failure of kitchen appliances is related to cockroaches, such as microwave ovens, induction cookers, etc. Cockroaches can easily get into household appliances and cause accidents. As a result, cockroaches are now also called "computer pests".

Cockroaches do not bite people and suck blood. In fact, cockroaches are not blood-feeding animals, they mainly feed on litter and kitchen waste. Sometimes, they also prey on insects or other small creatures.

The mouths of cockroaches are mainly used to chew or nibble on food, not to bite people or suck blood.

However, in rare cases, cockroaches may bite a person's finger. This is often because human ** sometimes attracts cockroaches in search of nutrients, not because they want to attack humans. Cockroach bites usually do not cause real harm to a person's body and do not spread disease.

However, if you are accidentally bitten by a cockroach, it is best to wash the wound with warm water and soap, which will avoid infection and relieve uncomfortable symptoms.

Blood-sucking, especially small.

Cockroaches have blood, but because it does not carry oxygen through hemoglobin, the blood is usually colorless.

Xiaoqiang lives almost everywhere, especially in hot and dark and damp places.

Take the kitchen room as an example, generally speaking, the kitchen sink, especially around the sewer pipe, the storage cabinets that are not opened often, the garbage cans that are not even disposed of, and the leftovers that have been eaten are Xiaoqiang's favorite perches.

Summer is also the breeding season for cockroaches, and when you go to the kitchen to get something at night, you will see cockroaches on the wall and ground fleeing as soon as you turn on the light. With the simplest and most brutal physical attack, he stepped on it, heard a crisp sound and flowed juice, thinking that he would clean up tomorrow morning, but he was sure to die, but the next day the corpse disappeared out of thin air.

The cockroach eats the cockroach medicine and returns to the perch, and after death, the same kind eats the remains and also dies due to the cockroach medicine, and the cockroaches at the last roost will almost die.

In addition, if you have a cat or a king at home, it is very likely that you will be eaten by mistake. Kittens and puppies are extremely curious and eat them before you can clean them up.

Since cockroaches do not oxygenate with hemoglobin, their blood is not red, but colorless. Only adult egg-laying females have orange blood because their livers produce an orange substance similar to vitamin A, which is sent to the ovaries for nourishment to develop embryos.

So you killed ......It should be a female and pregnant .........

You're in luck....It's so unfortunate....

Do insects have blood? I agree with the saying that insects have blood, and that the blood of insects is not necessarily red.

Here's a quote from a friend named Njut Tiger:

The blood of insects is actually an internal medium that transports nutrients and metabolic wastes, so it is also called hemolymph, which is composed of plasma and blood cells, and is carried out in the trachea because of respiration, so the blood of insects has no respiratory pigment. The blood of insects also often has a variety of colors, the common ones are yellow, orange-red, blue-green and green, etc., and the pigment substances contained in their blood make their blood show a specific color, such as carotene, riboflavin and flavin-nucleotides in the silkworm moth; flavonoids, fluorescein, and folic acid in silkworms; The green color of the larval blood of the butterfly is due to the co-presence of a yellow protein (whose cosylgroups are -carotene and lutein) and a blue protein (whose cogroup is biliverdin). A similar component is found in the green blood of the dispersed locust, however, the green blood of a green bug is the result of the presence of a -carotene-protein complex and an approximate anthocyanin.

These pigments in insect blood are generally thought to be obtained from food. In addition, the color of insect blood is also related to sex, such as the blood of larvae, pupae and adults of the butterfly, the female is green, and the male is yellow or colorless.

Cockroaches have blood. Since cockroaches do not carry oxygen through hemoglobin, their blood is not red but colorless. Only adult egg-laying females have orange blood because their livers produce an orange substance similar to vitamin A, which is sent to the ovaries for nutrient development.
