I found a cockroach-like insect in my balcony window, and I dare not ask anyone to identify it.

This is Blattella germanica, one of several cockroaches with the strongest reproductive adaptability in the world at present, and the best cockroach that permeates human life.

The reproductive speed of Blattella is thousands of times faster than that of common cockroaches. After about half a month, its young eggs can grow into adults, and the population is several times or even thousands of times that of ordinary cockroaches.

Blattella germanica can experience 4-5 generations a year.

Blattella germanica egg sheath has been dragged on the tail of the female until the larvae hatch. Nymphs therefore spread everywhere with their mothers.

Larvae molt for 5-7 times and become adults. The nymph period is 30-56 days.

The living habits of cockroaches are similar to those of ordinary cockroaches, and they like to move in hotels, Chinese and western kitchens, bars, restaurants, private rooms and other places. Don't be careless, you must take immediate action to clean it up.

The damage of Blattella germanica is also quite serious.

Blattella germanica not only eats books that destroy clothes, but also causes economic losses, the main harm is to spread diseases. When they chew food, they will vomit while eating. Besides Pseudomonas aeruginosa and Escherichia coli, they can also spread hepatitis virus. Studies have shown that Blattella germanica is also the main inducing factor of human asthma and allergy. According to reports, a pair of Blattella germanica can breed 400,000 offspring a year, and usually the life span can reach one or two hundred days.

In order to eliminate cockroaches, you must do the following work:

Clean up garbage and unused items, especially books, newspapers and magazines at home.

B. Check the bottom and back of furniture, as well as hidden places such as false ceilings, air ducts and wire troughs.

C. Fill the cracks and gaps on the ceiling, wall and floor with non-thermal insulation materials to achieve the best sealing effect.

D all cockroach remains and egg sheaths must be crushed and removed to prevent egg sheaths from hatching. (1: For the egg sheath, it must be burned. 2: Rush into the sewer. )

E try to avoid using plywood or ceiling wall for furniture, and choose furniture made of aluminum, stainless steel and plastic, which is easy to wash and has no heat preservation effect, so cockroaches are not easy to survive. It is best to keep furniture away from the wall, so it is not easy to hide cockroaches.

exclusive method

Keep the room clean and eliminate any environment where cockroaches may exist.

If there are cockroaches nearby, put drugs in places frequented by cockroaches to trap and kill them.

If there are many cockroaches, especially in the kitchen, you can spray a cockroach killer and then close the room. After a long time, you will find many cockroaches in the room when you open the door. Try a few more times. Although it can't be guaranteed to be completely eliminated, most of them must have been killed.

Take the initiative and put bait to kill cockroaches. For example, the cockroach board contains specially prepared pheromones to attract cockroaches, which can attract all cockroaches to the sticky board without any harm to the human body, and at the same time can prevent cockroaches from multiplying in large numbers.

Eliminate from the roots, use a mixture of cucumber skin, laurel or chrysanthemum petals and alcohol, and sprinkle it once a week in the place where cockroaches infest, which can eliminate newly hatched cockroaches.
