With a history of more than 150 years, Bayer has developed the "medicine of the century" - aspirin. After World War II, Bayer successively developed cardiovascular and cerebrovascular drugs, skin antifungal drugs, broad-spectrum antibiotics, etc., with strong strength. In 2018, it also completed the acquisition of Monsanto, making it the world's largest seed and pesticide company, which will control more than 25% of global seed and pesticide production.
 
Because Bayer specializes in R&D, unlike SC Johnson, which specializes in daily chemical products, Bayer sells active ingredient preparations rather than pesticides. The exterminators, exterminators, and exterminators on sale all contain only one ingredient, and the exterminators and exterminators are all baits, while the exterminators need to be diluted with water before use, so Bayer is also more suitable for long-term booby trap protection. These pesticides can be purchased in the Tmall flagship store opened by an agent.
 
Enemy removal is Bayer's insecticide against flying insects and reptiles, the main ingredient is deltamethrin, which is often used in cotton planting, as a household use, must be diluted in a low-concentration version. Because the insecticidal effect of this compound on mosquitoes, flies and other sanitary pests is higher than any known insecticide, and has the characteristics of fast insecticide and long residual effect, if it is a high concentration, it will have a certain impact on the human body. Among the eight isomers of deltamethrin, the dextro-cis isomer has the highest insecticidal activity, and if the isomers used are converted into dextro-cis isomers in the production process, it can be 5-10 times more effective than other pyrethroid insecticides, but this is also mostly used in agricultural preparations.
 
The user buys the enemy, a box of about 34 yuan, which is 4 5ML of medicine, equipped with a spray bottle, when using a medicine to be filled with 330ML of spray bottles, the formation of the solvent is a suspension dosage form, can be attached to the spraying surface, not easy to volatile, and not easy to decompose at high temperature. The effective range for fleas, mosquitoes and flies is 50 square meters, and the effective range for cockroaches is about 30 square meters.
 
Imidacloprid as a neonicotinoid high-activity insecticide jointly developed by Bayer and Japan Special Pesticide Co., Ltd. and industrialized, is a high-efficiency, low-toxicity broad-spectrum systemic insecticide, with both gastric toxicity and contact killing effects, long effective period, good control effect on stabbing mouthparts pests, so this ingredient is also used in Bayer's pet in vitro anthelmintic drugs.
 
Among the insecticides, the baits are both imidacloprid as the main ingredient, and the baixin contains 2.15% imidacloprid with a white emulsion texture, and the target is cockroaches. It is an anticidal bait, which is a transparent gel texture and contains 0.03% imidacloprid. Pests eat the bait and return to the nest to die, and will be eaten by other pests, so as to achieve the effect of killing the whole nest. Spot application is used in places where ants and cockroaches often appear, with an interval of about 1 meter, which can increase the density as appropriate, although the glue bait also uses HVL moisturizing technology to maintain the activity of the active ingredients, but to achieve the official claim of 6 months of protection, it still needs to be supplemented in a timely manner. Considering that pets may be eaten by mistake, bitters are added to the bait. The price of Bai Zhan is about 45 yuan, and Bai Shi Yi is slightly higher, about 70 yuan.
 
Bayer also has a Temid insecticide against termites, the main ingredient of which is fipronil and kills termites. However, it is not recommended to buy and dispose of it yourself, because ordinary people cannot accurately judge the location of the anthill, and improper treatment will allow termites to move the nest and cause greater damage, so it is recommended to directly hand it over to professionals.
