First, recommend several drugs:

1. Ruijinte (sprayed with water)

2. Xiaotaijian (cockroach medicine)

3. Poison Island (cockroach medicine)

4. Langping No.1 (cockroach medicine)

5. Gunner brand cockroach killing incense.

2. The pheromone in the gel bait lures cockroaches to feed.

3. When cockroaches return to their caves, they get sick and die and infect other cockroaches. Usually, the peak of cockroach death is 2-8 days after pesticide application.

4. Infected cockroaches will bite dead cockroaches, and they will be infected and die one after another. The infected female cockroach will carry the virus to the second generation in its egg sheath, resulting in a "domino" chain effect, which can achieve the continuous killing effect of repeated application of pesticides.

Third, the application steps of cockroach medicine:

1. First, apply the medicine in the place where cockroaches go in and out in a small amount, with a small amount and more points.

2. After one week, a small amount of points should be added, which is about 1/3 of the first medication.

3, check once a month, a small number of points.

Fourth, prevention and control methods of cockroaches:

There are many prevention and control methods of cockroaches, which can be summarized as follows:

1. Environmental prevention and control method: this method embodies the concept of prevention first. It is to create an environment that is not conducive to the invasion and life of cockroaches, so as to prevent them from entering or not living here. Such as plugging holes and plastering seams, cleaning, and managing food and water;

2. Physical prevention and control methods: generally, they are repelling and catching, such as using cucumbers and celery to repel cockroaches and electronic cockroach repellers. The cockroach house, sticky cockroach board, etc. are all caught.

3. Chemical control method: the core of this method is "killing", which is the most important and effective method to control cockroaches at present, mainly including:

(1), smoke method: including smoke bomb, cockroach killing smoke agent, hot smoke machine, etc. This method is quick and ineffective, so special attention should be paid to safety when using it;

(2) Retention spraying method: This is a traditional pest control method with quick and lasting effect, but it needs professional operation, so this method is also commonly used by professional companies;

(3) Poison bait method: the cockroach-killing drugs are prepared into bait that cockroaches like to eat, and placed in places where cockroaches haunt, so that cockroaches are poisoned and die after eating. This method is easy to operate, but it is limited by space, so it is extremely inconvenient to use it in various gaps.

(4) Glue bait method: This is a new cockroach killing method in recent years. Its main advantages are convenient use, safety and environmental protection. However, due to the numerous brands of this dosage form in recent years, it is inevitable that the fishy eye is mixed. A good glue bait should have three conditions: good fitness, strong attraction and long-term moisture retention.

4. Biological cockroach killing method: Because natural enemies can't be used to control cockroaches in cities at present, only biological agents are used to control cockroaches. At present, the mature biological agents are Poisonous Lidao and Langping No.1, the former is cockroach virus, and the latter is plant extract, that is, plant insecticide.

Although there are many methods to control cockroaches, it is difficult to solve the problem fundamentally by a single method. I have summed up a set of control methods of "clearing the source and consolidating the foundation", and adopted different comprehensive control methods according to different occasions to achieve the goal of treating both the symptoms and root causes. The so-called "clearing the source and consolidating the foundation" refers to the source management and regular consolidation, so as to achieve the purpose of treating both the symptoms and the root causes.

5. Common improper cockroach killing methods

1. Aerosol cockroach killing method. Aerosol can kill visible cockroaches, but it can't kill cockroaches hidden in deep cracks. Moreover, aerosols on the market basically belong to pyrethroid drugs, and cockroaches are extremely sensitive to this drug. After smelling the smell of this drug, cockroaches who were originally concentrated will flee in all directions, artificially accelerating their diffusion process. This is also the reason why many families use aerosol to kill cockroaches, which originally only occurred locally, but after being destroyed, they are everywhere.

2. Dichlorvos kill cockroaches. This is a common method to kill cockroaches in many places at present. This method has several disadvantages: first, it is toxic, easy to pollute food and has safety problems; Second, this medicine has fumigation effect, which is easy to cause poisoning events; Third, poor retention and short duration; Fourth, if there are no professional tools and professionals, it is difficult to achieve the desired results;

3. Local cockroach killing method. Many units and families always want to kill cockroaches in the places they see, such as the operating rooms of kitchens and restaurants, but cockroaches hide in various gaps most of the time. Once found in one place, it means that the whole space may happen. Therefore, it is necessary to kill cockroaches in a space as a unit, such as all parts of a family and all parts of a restaurant, in order to achieve the ideal effect;

4. Drive away. No matter what repellent method, it can't kill cockroaches fundamentally, especially electronic repellent, which is harmful to human body and other creatures.

In addition, we should correct a wrong understanding: the idea of killing cockroaches once and for all. Because no matter in theory or practice, it is impossible to kill cockroaches once, which is determined by the biological characteristics of cockroaches. At present, there is no medicine to kill the cockroach's egg sheath, so it will hatch again after a while, unless all the cockroaches' bodies are cleaned up after cockroach killing to ensure that no one is left. Therefore, cockroaches should be killed step by step. The so-called "clearing the source and consolidating the roots" means treating the source and consolidating it regularly to achieve the goal of treating both the symptoms and the root causes.
