Summer is here, and when cockroaches are rampant, cockroaches in some places can even fly, which is even more lethal. And with the change of time, cockroaches are also evolving. Many cockroach-killing tools that I used to think are easy to use will be less effective in the later stage. This is the main reason why I finally choose the research ingredients to kill cockroaches. Only by regular replacement can we achieve the best cockroach removal. effect ~
Cockroachicides belong to the category of pesticides. As long as the relevant registration number is provided, the active ingredients, toxicity and content can be found. The toxicity is divided into 5 grades from low to high. Toxic.
1. Imidacloprid (low toxicity)
At present, the most famous cockroach-killing gel bait on the market is imidacloprid, which is a new generation of chlorinated nicotine insecticide with high efficiency, low toxicity, quick effect and low residue. After the nest dies, other cockroaches eat the corpse, which will lead to a series of deaths, which can be said to kill a nest. The disadvantage is that the German cockroach is easy to develop resistance to it, and the effect will be weakened after repeated use. In addition, it is necessary to be careful not to let children and pets at home touch it, so as not to accidentally eat it.
2. Acephate (low toxicity)
The main component of Keling insect control cockroach gel bait is 2% acephate, which has a contact killing effect, and can also act on eggs, which can also have the effect of eliminating future problems.
3. Fipronil (slightly toxic)
The main component of the well-known Yukang cockroach bait is 0.05% fipronil. The toxicity of fipronil itself is higher than that of imidacloprid and acephate. If it is used to kill cockroaches at home, the content is lower than the first two to be safe. The toxicity of fipronil at 0.05% is slightly toxic, which is one grade lower than imidacloprid and acephate at about 2%. Inexpensive large bowl of green leaf cockroach bait, the active ingredient is also 0.05% fipronil.
4. Flumezone (slightly toxic)
As the name suggests, fluorite hydrazone is also a micro-toxic and highly effective cockroach and ant-specific disinfectant. Its toxicity is one level lower than that of low-toxicity. Family use with small children. BASF from Germany should have been heard by many people. The main ingredient of its cockroach bait is also 2% fluorite.
5. Chlorpyrifos (slightly toxic)
Chlorpyrifos (chlorpyrifos) is a non-systemic broad-spectrum insecticide with triple effects of stomach poisoning, contact killing and fumigation, and is classified as slightly toxic. At present, there are few cockroachicides that use clopyrifos as the main component, and the cockroach bait containing chlorpyrifos contains 0.2% of chlorpyrifos.
6. Crusader (low poison)
Propoxur (methyl phenylcarbamate) is also a non-systemic broad-spectrum insecticide with triple effects of stomach poisoning, contact killing and fumigation. It achieves killing effect by disrupting cockroach nerve axon conduction and inhibiting acetylcholinesterase activity. . At present, it is rarely used on cockroach bait, and it is generally used with cypermethrin as a spray.
7. Dinotefuran (slightly toxic)
Syngenta Oupote in the United States uses 0.1% dinotefuran (Avermectin benzoate), which blocks the sodium channels in the nerve cells of cockroaches, resulting in the death of cockroaches. It is slightly toxic and relatively safe.
8. PFDNV insect virus (microvirus)
In terms of serial killing ability, the brand developed by the School of Life Sciences of Wuhan University for 16 years: the active ingredient in Baile Wuda Oasis Toxicity Island – PFDNV virus also has a good effect, and achieves targeted killing of cockroaches through insect virus technology. Effect.
9. Pyrethroids (determined by content)
Pyrethrins are widely used in sanitary insecticides, mainly divided into deltamethrin, permethrin, difluthrin, etc. The dosage forms range from aqueous emulsions, suspensions, wettable powders to emulsifiable concentrates. According to the content, the toxicity can be divided into slightly toxic, low toxicity, moderate toxicity and so on.
Among the 9 common and effective cockroach-killing ingredients, the toxicity is not only related to the ingredients, but also to the content. From the point of view of the safety of active ingredients, the toxicity of oral ingestion is as follows: sulfamezone < acephate < imidacloprid < clopyrifos (chlorpyrifos) < propoxur, but in terms of skin contact, the toxicity is both It’s not too high, and the intake will be more than 2000-5000mg/KG to be poisoned. Basically, it is placed in scattered spots in the corners to avoid accidental ingestion by infants, and it will not cause much impact.
No active ingredient is completely harmless. There is no need to blindly believe in foreign products. Most of these 9 active ingredients are produced by domestic manufacturers. As mentioned at the beginning, cockroaches survive hundreds of millions of years longer than us and are very tenacious. Even if they kill adults, they must be completely killed. Cockroach eggs are also difficult. It is almost impossible to defeat it with a weapon, not to mention that the environment is always changing. For any product, cockroaches will develop resistance to the drug over time, and the ideal situation is to replace it every now and then. This is a long war.
