How to kill and prevent termites? Especially if you can't find an ant nest?

First, the harm of termites

The damage caused by termites is serious. According to the estimation of building damage in China, the damage caused by termites is more than 2 billion yuan per year, and the damage caused by termites accounts for more than 90% of the houses without termite prevention in Guangzhou.

Termites harm a wide range of objects, involving all fields of the national economy, including housing construction, water conservancy dams, communication equipment, transportation facilities, agricultural and forestry crops and landscaping. Termites mainly eat wood, leather and other animal and plant materials and objects, and can also harm plastics, paper products, wires, cables, polymer materials, and even soft metal products (such as lead, aluminum, tin, etc. ) you can eat it.

The harm of termites is very hidden, and it is not easy for ordinary people to detect it. Once discovered, it will often cause certain losses.

Second, the way termites invade houses

There are three main ways in which termites invade houses and cause harm:

1. It is harmful to climb into the room from underground soil;

4. When winged termites fly separately from April to July every year, they fly indoors and nest and breed in suitable hiding places;

It is harmful for people to carry termites indoors, such as bringing old furniture with termites indoors when moving.

Three. Living habits of termites

Termites are insects that nest and live in groups. Take domestic termites as an example. The number of termites in a mature termite nest is more than 300,000, and the number of large termites can reach several million. Termites in termite nests have different division of labor, generally divided into worker ants, soldier ants, queen ants and queen ants. There will also be breeding ants and individuals who supplement breeding ants in mature termite nests.

Mature domestic termites in Guangzhou usually fly out of their nests at 7-8 pm from April to July to find a suitable place when the weather conditions are suitable. Male and female reproductive ants chase and pair after shedding their wings, build new nests and gradually breed offspring. After 1-2 years of development and reproduction, this new termite nest will produce breeding ants with wings.

When winged breeding ants fly away from their nests, they have strong phototaxis. Sometimes the lights are not turned on at home, and the reflection of the surrounding lights on the window glass can also attract winged breeding ants to fly indoors to nest. Termites like to use wood to build nests in dark and humid places. Residents should pay attention to avoid using less wood for decoration in wet places.

A single termite in a nest group can not only harm the surrounding objects, but also build roads and feed in the soil 40-50 meters away from the nest, so there must be an ant nest where there are ants, but the place where there are ants is not necessarily the place where the ant nest exists. That's the reason.

Fourth, the control of termites.

This paper mainly introduces the prevention and control of household termites which are the most harmful to the greening of houses and surrounding areas.

Termite prevention and control are two different concepts. For example, the prevention of new houses is three ways to prevent termites from invading houses. Targeted measures, such as fully spraying chemicals on the first floor of the new house or the soil layer in the basement, and setting anti-ant ditches around the outer wall of the house, are all aimed at preventing termites from crawling into the house and causing damage. The termite control treatment of indoor decoration materials (wood) is mainly aimed at controlling indoor scattered breeding ants. Because the decorated wooden materials are treated with pesticides, termites will be poisoned or have repellent and antifeedant effects, so as to drive away termites and achieve the purpose of prevention and control.

Termite control refers to the discovery of exposure signs of termites in houses, such as ant paths, flying holes, excrement, holes in damaged objects, etc. And invite termite control professionals to inspect and poison termites. Because the harm of termites is very hidden, there is a process from mild to serious harm, so residents should always clean indoor hygiene and check the status of wooden decoration. If there are signs of termite damage, please ask termite control professionals to check and kill them in time. It is not advisable to spray by yourself, so as to avoid termites scattering and escaping, which increases the difficulty of control.

In addition, from April to July every year, when residents find winged breeding ants flying into indoor lights at 7-8 pm, they should immediately put out the indoor lights and close the windows to prevent termites from flying into the room to nest. For termites that have flown indoors, drugs that can eliminate the "four pests" can be sprayed.
