An active substance is an ingredient that has an effect on an organism. Sumitomo Chemical’s active substances have the effects of paralysing or killing insects and other small creatures that are harmful to human and animal health, including mosquitoes, ticks, fleas, mites, cockroaches and flies.
Many of our active substances are pyrethroid insecticides, which are organic compounds similar to those found in chrysanthemum flowers. From these powerful active substances, we have created specialised insecticides that have various effects on a variety of different pests.
Mosquitoes are found in nearly every region of the world, from the arctic to the tropics, and can survive severe winters or dry seasons depending on the region. They can be found breeding in all types of water, both clean and polluted.
Female mosquitoes require blood from living hosts in order for their eggs to develop. In cooler climates, they are mainly a biting nuisance, but in more tropical regions they pose a real threat to animals and humans as they are vectors transmitting serious diseases from host to host. These include yellow fever, west Nile virus, dengue fever, filariasis and, most notably, malaria.
It is estimated that 300-500 million people in nearly 100 countries worldwide are infected with malaria. Of these, some 2.5 million will die each year. This makes the mosquito the most dangerous animal in the world.
Sumitomo Chemical has created highly effective mosquito-killing formulations in the form of plug-in vaporiser liquids and vaporiser mats. See our products.
Ticks are ectoparasites: small arachnids which live by feeding on the blood of living hosts – mostly mammals and birds. They are found across the globe, especially in warm, humid climates. They cannot fly or jump, but quickly climb from vegetation on to a host – for instance, when a dog brushes past them through long grass.
Ticks are often infected with pathogens. They attach to their host while feeding (embedding the head in the skin), in some cases for several days, during which time they may pass on their infections.
Major tick-borne diseases affecting humans, pets or livestock include Lyme disease (the main risk in the UK), babesiosis, ehrlichiosis, Colorado tick fever, Rocky Mountain spotted fever, African tick bite fever, Crimean Congo hemorrhagic fever, tularemia, tick-borne relapsing fever, tick-borne meningoencephalitis, canine jaundice, and bovine anaplasmosis.
