Are termites harmful to human body?

Generally speaking, they appear because the weather is wet. They are harmless to human body and won't bite. In the south, termites, also known as termites, flood insects and flood ants, are a worldwide pest, and are also called the five largest pests in the world with tsetse flies, ticks, mosquitoes and armyworms. Termites are socially polymorphic harmful insects, and a nest of termites can be divided into reproductive ants and sterile ants. Breeding ants include queen ants, queen ants, long-winged breeding ants, short-winged breeding ants and wingless breeding ants, and sterile ants include worker ants and soldier ants. Termites have a clear division of labor, and breeding ants specialize in breeding and reproduction. Worker ants are responsible for building nests, building roads, pumping water, feeding, carrying ant eggs, feeding and cleaning ant nests, and soldier ants are responsible for defending ant nests, defending worker ants' activities and flying long-winged breeding ants safely. First, the harm of termites (a) the main manifestations of termite harm in families 1. Destroy buildings and building components, endangering the safety of houses. 2. Destroying components and decoration materials will make the renovated family unrecognizable. 3. Destroy furniture, cables and pipes, clothes, books, etc. When termites fly away, it will also cause family panic. (2) Termite hazard characteristics 1. Concealed. Termites are usually sent out through mud roads or mud built by themselves, and their nests are mostly underground, in walls or in wood, so they are not easy to be found. 2. extensiveness. Everything in the house may be damaged or destroyed by termites. 3. Severity. Domestic termites can destroy clothes, books, furniture and daily necessities, and even lead to line damage, fire and house collapse. 2. Common Species and Habits (1) Common species of termites can be divided into three types according to their nesting characteristics, habitat habits and requirements for habitat environment: wood termites, civil termites and soil termites. Because soil-dwelling termites mainly harm dams and garden green spaces, they do not harm families, so they are not introduced here. 1. Woody termite wood is the only habitat of this termite. Nests and groups are in the Woods, and once they leave, they can't survive. This termite has a fixed habitat (also their feeding place) and rarely invades other wood. Nest groups are small, and nests without fixed structures are easy to spread due to business activities. 2. Terrestrial termites are the most widely distributed and harmful termites in the family. Can nest in cracks in soil or brick walls, or in the roots and trunks of wood or living trees; Or both, that is, a nest of termites, some in underground soil and some in wood. Habitat and feeding ground are sometimes consistent, sometimes inconsistent, but relatively close. This kind of termites has a complex nest group, a fixed nest structure and a large number of individuals, ranging from thousands to hundreds of thousands. (2) Habitual termites are polymorphic social insects with complex life history. Most termites generally start from eggs and hatch young ants. Young ants can be divided into soldier ants, worker ants and Ruo ants. If ants develop, they can be divided into supplementary queens, queens and long-winged breeding ants. As soon as the flight season arrives, the winged breeding ants begin to fly away from their nests, and after shedding their wings, they become primitive ants and queens. 1. In a termite colony, there is a clear division of labor among grades, but they are interdependent and cooperative. Under normal circumstances, termites can't live alone without nests, except for breeding ants with long wings. This kind of dependence and cooperation between different levels is very important to the development of ant nests. 2. Active hidden termites are generally afraid of the sun and like to move in dark places, or build hidden ant paths to fly, feed and pump water. Sometimes we have short outdoor activities in the evening. 3. Highly sensitive termites are highly sensitive to external environmental conditions such as sunlight, temperature, humidity, invasion by foreign enemies, etc. Once the ant path or nest is damaged or exposed, the soldier ants will immediately come out to defend against the enemy, while the worker ants are busy repairing it. Worker ants and soldier ants can also send messages by shaking their bodies and making sounds. 4. Cleaning habits Termites pay great attention to hygiene. They always keep their nests, ant paths and themselves clean. Ant paths are often clean and smooth, and they will be removed quickly when encountering debris. Termites often lick each other to keep themselves clean. 5. Once the external environmental conditions are suitable, the long-winged breeding ants will fly out of the fly hole to develop new nests when they mature. Different kinds of termites have different flying seasons and times. 6. Termites are mainly fed with wood and cellulose-containing substances. Except a few varieties, there is generally no habit of storing grain. 7. The spread winged adults (1) spread termites separately, and when they are mature, they fly out of the nest to mate, and when they meet a suitable environment, they can develop into new groups. (2) Spread If ants are not effectively controlled, termites will spread rapidly, from one point to another and from one house to another. (3) The imported termites will spread from one place to another with the transportation of materials. If you buy wooden furniture or home improvement materials, sometimes termites will be brought into your home. Termites can also spread over long distances by means of transportation. Third, preventive measures The key to termite control is to pretreat the house, which should be carried out before the house starts to be built or rebuilt, expanded and renovated. (1) termite prevention in new houses 1. On-site treatment before construction. Mainly cut off the termite food left over from the site, indirectly eliminate termites, and reduce the possibility of termite survival. 2. Termite control of wall base, ground and soil. If mosquitoes are found in the new house, they must be thoroughly treated, including killing ground termites by physical methods and chemical drugs, leaving no hidden dangers. 3. Pretreatment of wood components. The purpose of wood component treatment is to cut off the pumping line of termites, avoid the direct harm of termites, and prolong the service life of wood components. Pretreatment of wooden components can be done by brushing termite control drugs and soaking. And can also be treated at a high temperature above 60 DEG C.. (2) Termite prevention of decoration materials When a family wants to decorate, it is necessary to pretreat the home improvement materials to avoid bringing termites indoors. The pretreatment method of home improvement materials is basically the same as that of wooden components. (3) Keep indoor and outdoor clean, remove sundries, keep indoor items in order, and leave no garbage that can attract termites, especially sawdust, paper and worn-out clothes.
