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.
Mosquitoes are ectoparasites, surviving by feeding on the blood of living hosts. 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.
Adult fleas live exclusively as ectoparasites of warm-blooded animals, especially mammals. Cat fleas (Ctenocephalides felis) are responsible for most domestic flea infestations.
Besides the itchy, biting nuisance, fleas can also act as a vector for disease, transmitting various harmful viruses and bacteria or tapeworms to their hosts.
The most serious infection they can spread to humans is bubonic plague, transmitted by rodent fleas. Rodent fleas have in the past been responsible for serious epidemics of this disease, the most famous being the Great Plague of London in 1665.
Sumitomo Chemical has a water-based insecticide spray formulation that kills fleas rapidly and keeps working for up to six months. See our products.
House dust mites, as their name implies, thrive in human dwellings around the world, living off organic debris – particularly the sloughed skin flakes that make up household dust. They are mainly found in furniture, carpets, mattresses and pillows.
Dust mites do not bite, but their faeces contain very potent enzymes which often induce allergic reactions in humans (and pets), especially respiratory conditions like allergic rhinitis and asthma.
Sumitomo Chemical distributes ready-made aerosol sprays that kill dust mites rapidly and keep working for up to four weeks. See our products.
Cockroaches are extremely resilient insects that can survive in many habitats, even in the Arctic – but most are found in warm, humid climates.
A few species of cockroach have become problematic pests. These feed on human foodstuffs, wallpaper, leather and other items found in homes and commercial premises. A building may become infested by accidentally introducing eggs or adults in laundry or construction materials, or by the cockroaches entering through drains or rubbish chutes in search of food.
Cockroaches can carry and spread many diseases to humans, some of them serious, such as dysentery, gastroenteritis, typhoid and poliomyelitis. They are also associated with allergic reactions and asthma symptoms.
Sumitomo Chemical distributes ready-made insecticide aerosol and trigger spray formulations that rapidly kill cockroaches and keep the sprayed area treated for up to three months. See our products.
Houseflies are extremely common insects found all over the world, which are highly active indoors. In warmer climates, houseflies remain active and reproduce throughout the year. They will feed indiscriminately on any liquefiable food.
Apart from the obvious nuisance they cause, houseflies are very unhygienic; they frequently feed on rotting food and faeces, and subsequently land and feed on food intended for humans consumption, constantly depositing their own faeces. In this way, they can transmit intestinal worms and are potential carriers of some serious diseases such as dysentery, gastroenteritis, typhoid, cholera and tuberculosis.
Sumitomo Chemical has aerosol and trigger sprays that efficiently knock-down and kill houseflies. See our products.
Ants are found almost everywhere on the planet; there are an estimated 22,000 difference species of these insects. They live in highly organised societies and survive by a wide variety of means, from farming and ‘milking’ aphids or growing and eating fungus, to preying on termites and other ants.
Foraging worker ants travel widely in search of food, presenting a problem for humans when they enter environments intended to be kept sterile. If they detect sweet food in a kitchen or food storage facility, that location may quickly be overrun and contaminated by ants, resulting in food being discarded for hygiene reasons. Many types of ant can also sting or bite people and animals.
Sumitomo Chemical has an insecticide aerosol and spray formulation that rapidly kills ants and keeps the sprayed area ant-free for up to three months. See our products.
Wasps are closely related to ants, with tens of thousands of species spread across the globe. Like ants, many species of wasp are social insects with new nests being constructed every year. Wasp nests may be located underground, in buildings or in trees or bushes. Social ants may prey on other insects, but they primarily forage for sugary foods like fruit and nectar – along with the cakes and soft drinks at people’s summer picnics.
Wasps have a very strong attraction to sweet foods and drinks, and cause a nuisance when they enter kitchens, bakeries, restaurants or food preparation areas. Food stuffs can be contaminated by wasps walking and feeding on them, and people may be disturbed or even stung.
Sumitomo Chemical has ready-made aerosol and spray formulations that efficiently knock-down and kill wasps. See our products.
Moths are insects (of the order Lepidoptera – or ‘scaly wing’) related to butterflies, found all over the world. Most species are nocturnal.
It is the larvae of certain moth species that are responsible for causing damage to stored products. The most well-known problem is with clothes moths; their larvae feed on fabrics containing wool and silk, leaving holes in clothes along with their waste products and webbing.
Other moth species are major agricultural pests, with the larvae eating their way through corn or fruit farms.
Sumitomo Chemical’s active substance, Vaporthrin®, is highly effective at repelling moths thanks to its high volatility at room temperature and long-lasting activity. It can be added to a paper carrier to be placed inside closets or wardrobes, making it an excellent pyrethroid alternative to traditional mothballs. See our active substances.
