Bed Bug Eradication
Bed bugs, or Cimicidae, are small parasitic insects. The term usually refers to species that prefer to feed on human blood. Early detection and treatment are critical to successful control. According to a survey, the most commonly infested places are the mattress (98.2%), boxspring (93.6%), as well as nearby carpets and baseboards (94.1%).Gangloff-Kaufmann, J.C. et al. 2006 Bed bugs in America: a pest management industry survey. Am. Entomol. 52: 105–106 In fact, bed bugs thrive in areas where there is an adequate supply of available hosts, and plenty of cracks and harborages within of the host. Because treatments are required in sleeping areas and other sensitive locations, methods other than chemical pesticides are in demand. Treatments can be costly, laborious, time consuming, repetitive, and embarrassing, and may entail health risks. Public health laws Bed bug infestations spread easily in connecting units and have negative effects on psychological well-being and hous ...

Cyhalothrin
Cyhalothrin is the ISO common name for an organic compound that, in specific isomeric forms, is used as a pesticide. It is a pyrethroid, a class of synthetic insecticides that mimic the structure and properties of the naturally occurring insecticide pyrethrin which is present in the flowers of ''Chrysanthemum cinerariifolium''. Pyrethroids such as cyhalothrin are often preferred as an active ingredient in agricultural insecticides because they are more cost-effective and longer acting than natural pyrethrins. λ-and γ-cyhalothrin are now used to control insects and spider mites in crops including cotton, cereals, potatoes and vegetables. Structure and stereochemistry : Gamma-cyhalothrin and lambda-cyhalothrin are the active ingredients in the current commercial products based on cyhalothrin. Both are cyanohydrin esters of cis-3- Z)-2-chloro-3,3,3-trifluoropropenyl2,2-dimethylcyclopropanecarboxylic acid. All of the insecticidal activity is due to the proportion of absolute ster ...

Steaming
Steaming is a method of cooking using steam. This is often done with a food steamer, a kitchen appliance made specifically to cook food with steam, but food can also be steamed in a wok. In the American southwest, steam pits used for cooking have been found dating back about 5,000 years. Steaming is considered a healthy cooking technique that can be used for many kinds of foods. Because steaming can be achieved by heating less water or liquid, and because of the excellent thermodynamic heat transfer properties of steam, steaming can be as fast, or faster, than cooking in boiling water, as well as being more energy efficient. History Some of the world's earliest examples of steam cooking were found in China's Yellow River Valley, early steam cookers made of stoneware have been found dating back as far as 5,000 BCE. And also in Gunma Prefecture, Japan, created during the Stone Age. Some of the second earliest examples of steam cooking have been found in Italy and Sardinia, cre ...

Sulfuryl Fluoride
Sulfuryl fluoride (also spelled ''sulphuryl fluoride'') is an inorganic compound with the chemical formula, formula SO2F2. It is an easily condensed gas and has properties more similar to sulfur hexafluoride than sulfuryl chloride, being resistant to hydrolysis even up to 150 °C. It is neurotoxic and a potent greenhouse gas, but is widely used as a fumigant insecticide to control termites. Structure, preparation, reactions The molecule is tetrahedral with C2v symmetry point group, symmetry. The S-O distance is 140.5 pm, S-F is 153.0 pm. As predicted by VSEPR, the O-S-O angle is more open than the F-S-F angle, 124° and 97°, respectively. One synthesis begins with the preparation of potassium fluorosulfite: :SO2 + KF → KSO2F This salt is then chlorinated to give sulfuryl chloride fluoride: :KSO2F + Cl2 → SO2ClF + KCl Further heating at 180 °C of potassium fluorosulfite with the sulfuryl chloride fluoride gives the desired product: :SO2ClF + KSO2F → ...

Biocide
A biocide is defined in the European legislation as a chemical substance or microorganism intended to destroy, deter, render harmless, or exert a controlling effect on any harmful organism. The US Environmental Protection Agency (EPA) uses a slightly different definition for biocides as "a diverse group of poisonous substances including preservatives, insecticides, disinfectants, and pesticides used for the control of organisms that are harmful to human or animal health or that cause damage to natural or manufactured products". When compared, the two definitions roughly imply the same, although the US EPA definition includes plant protection products and some veterinary medicines. The terms "biocides" and "pesticides" are regularly interchanged, and often confused with "plant protection products". To clarify this, pesticides include both biocides and plant protection products, where the former refers to substances for non-food and feed purposes and the latter refers to substances ...

Chlorpyrifos
Chlorpyrifos (CPS), also known as Chlorpyrifos ethyl, is an organophosphate pesticide that has been used on crops, animals, and buildings, and in other settings, to kill several pests, including insects and worms. It acts on the nervous systems of insects by inhibiting the acetylcholinesterase enzyme. Chlorpyrifos was patented in 1966 by Dow Chemical Company. Chlorpyrifos is considered moderately hazardous to humans (Class II) by the World Health Organization based on acute toxicity information dating to 1999. Exposure surpassing recommended levels has been linked to neurological effects, persistent developmental disorders, and autoimmune disorders. Exposure during pregnancy may harm the mental development of children. In the United Kingdom, the use of chlorpyrifos was banned as of 1 April 2016 (with one minor exception). As of 2020, chlorpyrifos and chlorpyrifos-methyl were banned throughout the European Union, where they may no longer be used. The EU also applied to have ch ...

Chlorfenapyr
Chlorfenapyr is a pesticide, and specifically a pro-insecticide (meaning it is metabolized into an active insecticide after entering the host), derived from a class of microbially produced compounds known as halogenated pyrroles. History and Applications Chlorfenapyr was developed by Cyanamid from the natural product dioxapyrrolomycin, which was isolated from ''Streptomyces fumanus''. The United States Environmental Protection Agency initially denied registration in 2000 for use on cotton primarily because of concerns that the insecticide was toxic to birds and because effective alternatives were available. However, it was registered by the EPA in January, 2001 for use on non-food crops in greenhouses. In 2005, the EPA established a tolerance for residues of chlorfenapyr in or on all food commodities. Chlorfenapyr is also used as a wool insect-proofing agent, and was introduced as an alternative to synthetic pyrethroids due to a lower toxicity to mammalian and aquatic life. ...

Dichlorvos
Dichlorvos (2,2-dichlorovinyl dimethyl phosphate, commonly abbreviated as an DDVP) is an organophosphate widely used as an insecticide to control household pests, in public health, and protecting stored products from insects. The compound has been commercially available since 1961 and has become controversial because of its prevalence in urban waterways and the fact that its toxicity extends well beyond insects. Since 1988, dichlorvos cannot be used as a plant protection product in the EU. Use Dichlorvos is effective against mushroom flies, aphids, spider mites, caterpillars, thrips, and whiteflies in greenhouses and in outdoor crops. It is also used in the milling and grain handling industries and to treat a variety of parasitic worm infections in animals and humans. It is fed to livestock to control botfly larvae in manure. It acts against insects as both a contact poison and an ingested poison. It is available as an aerosol and soluble concentrate. It is also used in pet flea ...

Diazinon
Diazinon (IUPAC name: ''O'',''O''-Diethyl ''O''- -methyl-6-(propan-2-yl)pyrimidin-2-ylphosphorothioate, INN - Dimpylate), a colorless to dark brown liquid, is a thiophosphoric acid ester developed in 1952 by Ciba-Geigy, a Swiss chemical company (later Novartis and then Syngenta). It is a nonsystemic organophosphate insecticide formerly used to control cockroaches, silverfish, ants, and fleas in residential, non-food buildings. Diazinon was heavily used during the 1970s and early 1980s for general-purpose gardening use and indoor pest control. A bait form was used to control scavenger wasps in the western U.S. Diazinon is used in flea collars for domestic pets in Australia and New Zealand. Residential uses of diazinon were outlawed in the U.S. in 2004 because of human health risks but it is still approved for agricultural uses. An emergency antidote is atropine. History Diazinon was developed in 1952 by the Swiss company Ciba-Geigy (now Novartis) to replace the formerly dominan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permethrin
Permethrin is a medication and an insecticide. As a medication, it is used to treat scabies and lice. It is applied to the skin as a cream or lotion. As an insecticide, it can be sprayed onto clothing or mosquito nets to kill the insects that touch them. Side effects include rash and irritation at the area of use. Use during pregnancy appears to be safe. It is approved for use on and around people over the age of two months. Permethrin is in the pyrethroid family of medications.

Fipronil
Fipronil is a broad-spectrum insecticide that belongs to the phenylpyrazole chemical family. Fipronil disrupts the insect central nervous system by blocking the ligand-gated ion channel of the GABAA receptor and glutamate-gated chloride (GluCl) channels. This causes hyperexcitation of contaminated insects' nerves and muscles. Fipronil's specificity towards insects is believed to be due to its greater binding affinity to the GABAA receptors of insects, than to those of mammals, and to its action on GluCl channels, which do not exist in mammals. , there did not appear to be significant resistance among fleas to fipronil. Because of its effectiveness on various pests, fipronil is used as the active ingredient in flea control products for pets and home roach traps as well as field pest control for corn, golf courses, and commercial turf. Its widespread use makes its specific effects the subject of considerable attention. This includes ongoing observations on possible off-target h ...
