What is the common name of a cockroach What kind of cockroach is this?

Northern cockroaches: flattened, black-brown, usually medium in size. The head is small and can move.

The larvae that have just hatched from the egg sheath are gathered around the egg sheath, which is white, and then the color gradually darkens and spreads out, and the larvae are similar in shape to adults, but the body is small, wingless, and the sexual organs are immature. The larvae develop slowly. It must undergo multiple molts to grow gradually, and the number of antennae and tail whiskers also increases with age.

After the last molt, the larvae grow wings and emerge into adults. Freshly molted larvae and newly fledged adults are also white and gradually darker in color, so that a species of cockroach can also change according to environmental conditions in a population of Momeng. The larval stage is long, generally lasting about 30 450 days.

What environment do cockroaches like:

Cockroaches prefer to choose warm, moist, well-fed and crevice-filled places to live, which are the 4 basic conditions they need to breed. All buildings where people live and live generally have these conditions, so cockroaches have become a sanitary pest that infests thousands of households. Warmth and love tide is an important habit of cockroaches.

This is a German cockroach, which is also a type of cockroach.

Here's how to get rid of cockroaches:

1. Laundry detergent is a highly effective agent for trapping cockroaches, and its effect is even better than some chemical insecticides. The method is to sprinkle the laundry detergent on the place where the cockroach may be infested, and it will die after eating the laundry detergent.

2. Take one part of borax and one part of flour, a little sugar, mix well to make balls the size of rice grains, sprinkle them on the haunt of it, and be poisoned to death after eating.

3. It is a hot soapy water killing method, add a piece of soap to 4 liters of hot water, dissolve it and spray it directly on the cockroach, which can effectively kill cockroaches.

4. It is a soda cockroach removal method, half of sugar and baking soda powder, placed in the cockroach infested place, about 3 14 days later, the cockroaches will disappear, it is said that this is also the most commonly used cockroach prevention secret recipe in the United States.

5. It is a boric acid mopping and cockroach prevention method, after dissolving an appropriate amount of boric acid with hot water, wipe the floor with a mop or rag, after drying, white boric acid crystals will penetrate into the cracks of the floor, which can prevent cockroaches, ants, etc.

6. It is an anti-cockroach method for orange and lemon peels, after drying or roasting the peel of oranges and lemons, and placing them in various cabinets, it not only has the role of flavor agent, but also has a certain anti-cockroach effect.

German cockroach control methods:

Residual spraying and poison bait are the two basic methods of chemical control of German cockroaches. Because the residue on the surface of the indoor surface can remain for more than 3 months after residual spraying, it is difficult to remove, so in the prevention and control of German cockroach, we should avoid indiscriminate large-scale spraying on the ground, walls and ceilings, focusing on the activities and habitats of German cockroaches, especially the gaps close to water sources and food.

The dosage forms suitable for residual spraying include microencapsulated suspension agent (CS), emulsifiable concentrate (EC), aqueous emulsion (WP), suspension agent (SC), wettable powder (WP), etc.

Cockroach poison bait has been rapidly promoted because of its small environmental pollution, safe use and reliable effect. Cockroach poison bait dosage forms include ointment, glue bait, granular poison bait, poison bait box, etc., which are suitable for schools, hospitals, offices and other places that are sensitive to insecticides.

When using poison bait, it must be applied in crevices or in areas where German cockroaches gather. If the density is high, the retention spraying should be carried out first, and after the density is reduced, the poison bait should be used to consolidate the cockroach control results.

Due to its advantages of good etherealness and long lasting effect, poison powder is also often used in the prevention and control of German cockroaches. Especially when dealing with the inside or deep crevices of some precision instruments that cannot be sprayed, the use of toxic powder can achieve good results.

Cars, boats, basements and other confined places can be used fumigants to control German cockroaches. The smoke has strong penetration and completely exterminates cockroaches, but the disadvantage is that it is not effective and must be coordinated with other control measures. The fumigant is more polluting and dangerous to people and animals, so attention should be paid to safety when using it.

Cockroaches prefer to choose warm, moist, abundant food and crevices to live, which are the 4 basic conditions they need to breed. These conditions are generally met in all buildings where humans live and live, so cockroaches have become sanitary pests that infest thousands of households.

Cockroaches like darkness and fear light, and they come out at night. During the day, they hide in dark and dark places, such as indoor furniture, crevices in walls, and corners. At night, especially after the lights are turned off, people go out to do activities or forage for food.

As a result, about 75% of the 24-hour day is spent at rest.

Cockroaches are flat and can hide in very narrow crevices. For example, the adults and nymphs of the German cockroach can hide in crevices as small as a millimeter, and when they inhabit the crevices, their antennae often extend outward, waving from time to time, and they remain vigilant.

Cockroaches also have a habit of living in groups. It can often be found in a single habitat, always with a few or a few.

Ten or hundreds of them are clustered together, mainly due to the attraction of pheromones. Both adults and nymphs of cockroaches secrete an "aggregate pheromone", which is secreted by the rectal pad and excreted in the stool. In places where cockroaches live, it is common to see traces of their feces, and the more dung they have, the more cockroaches gather.

It can be seen that in the prevention and control of cockroaches, doing a good job of hygiene is an important measure.
