There are many termites at home, how to kill them. Urgent. . . .

Because the colony of termites is relatively small, and there are often several groups in a building, there is no fixed formation, which brings certain difficulties to the prevention and control work. When controlling termites, the following points should be done:

1. Find live termites, ant paths or fly holes, and spray the termite killer on the bodies of termites or in the ant paths and fly holes.

2, in the wooden door, window frame drilling pouring termite control liquid.

3. Drill holes in the wooden floor or pry the floor open, and spray termite control liquid on the opposite side of the floor.

4, the floor beam, especially at the entrance to the wall, to drill a hole, spray out ant potion.

5. Drill holes at both ends of the wooden beam (inserted into the wall) and inject ant killing powder or liquid medicine.

6, clapboard pry open the top edge, spraying termite solution.

7. The soil around the building should be sprayed with a large area of liquid medicine.

In general, termite prevention in building decoration should include:

① Ground treatment. Floor decoration is nothing more than installing wooden floors and non-wooden floors. Before installing the ridge and fence, spray the ground with termite control medicine. Before laying the floor, wooden ridges and pavilions should also be treated with drugs by spraying or brushing. If the wooden floor is laid directly on the ground, it only needs to be sprayed on the ground. Used for non-wood (decorated with glazed tiles, slates or grindstones) ground treatment. You just need to treat it with drugs around the ground against the wall.

(2) Treatment of wall surface. Wall decoration includes the installation of dado or dado, or wallpaper or wall covering, as well as tiling or painting, painting, etc. To treat such a wall, spray can be used to carry out drug prevention treatment on the wall. The general processing range (height and width) exceeds the actual decorative surface 10 cm or more.

③ Treatment of wood structure. Wood structures often involved in decoration usually include doors, window frame sheaths, fixed cabinets, dados or dados, suspended ceilings, stairs, etc. Used for the installation of dado or dado, stairs, ceilings, etc. , processing can refer to the first two items.

Second, remedial termite prevention and treatment in building decoration. After the building decoration is completed, remedial termite prevention treatment can also be carried out. The way is to increase the dosage of pesticides, so that the liquid medicine can cover the treatment point as widely as possible through overflow, forming a broad protective barrier to keep termites out of the drug protective barrier.

Termite prevention 1, soil treatment-4 liters -5 liters per square meter. Spray treatment.

2, used to brush the board.

3, square material-soak for 30 minutes.

4. Killing termites-according to the method of killing scattered termites-pouring.

Precautions; 1, this product is toxic to bees, fish and silkworms, and must be used far away from the culture area. It is forbidden to clean pesticide tools in rivers, ponds and other water bodies.

2. Because this medicine has certain toxicity, avoid touching the skin when using it. Wear a mask and gloves when using this medicine. Do not eat or drink during application, and wash your hands and face in time after application.

Termite control:

First, try to find an ant nest or an ant path in the discovered ant harm. First of all, the powder for killing ants should be sprayed on termites in ant nests or ant passages as far as possible, so that they can infect each other and achieve the effect of killing.

Second, in the place where termites are found, drill holes at a certain distance from the wooden door window frame to inject liquid medicine, and spray liquid medicine to the surrounding soil at the same time, so that both wood and soil contain certain toxins, and termites will be poisoned and die if they touch the poison.

3. Trapping method: Trapping piles, traps, traps and baits can be set up at the place where termites are found. The above three methods can be used alone or in combination. In addition, there are fumigation insecticidal methods, such as the hot air insecticidal method used abroad now, which has also achieved certain results. There are many ways to kill termites, but specific methods should be formulated according to the position and surrounding environment of termites.

4. What's the difference between termites and general pesticides?

General pesticides are fast killers and termites are slow killers. That is, termites can only die after eating toxic food for 3-7 days. Because termites have the habit of sucking each other, and other termites rely on worker ants to feed, according to this living habit of termites, the whole nest of termites is destroyed by mutual transmission. Therefore, according to different uses, the requirements for drugs are different. Preventive medication in new houses should have the characteristics of high efficiency, low toxicity and no environmental pollution. Therefore, the state has strict requirements for termite control drugs.

Five, the basis of drug treatment

1. drug treatment of foundation: after the foundation is dug, spray drugs on the bottom and two walls of the foundation as required.

2, building backfill soil plus or minus zero (including aproll slope), laying cement ground, spraying drugs on the soil surface.

3, wooden door window frame after production, namely besmear brushs anti-ant drugs.

4, other wooden components of drug treatment, according to the situation in general, mostly by brushing or dipping method.

First, the eradication of Taiwan's milk termites (domestic termites)

The nest of Taiwan's milk termites is a concentrated large nest, which consists of many nest pieces mainly made of wood fibers, and also includes some honeycomb and sheet structures bonded by soil, termite feces, sand and secreted saliva, so it is also called dry nest. The shape of nests is mostly oval, and some nests have different regular shapes due to the limitation of environmental matrix. The diameter of nests is generally 40-50 mm, and some of them exceed1m. There are two kinds of nests: main nest and auxiliary nest. There is only one main nest and multiple sub-nests. Termites in the main nest and the auxiliary nest often contact each other. Isotope tracing measurement shows that the main nest and the auxiliary nest can contact 1 time within 4 hours. The colony in the nest is huge, and the total number of individuals in its vigorous and mature colony is as many as several million.

According to the investigation of mud-wood structure and brick-wood structure houses by Guangdong Insect Research Institute, domestic termites can nest in mud walls, and the most common nesting location is at the corner of lintel and the junction of beam and wall, where food is abundant and there is room for the development of ant nest space. However, in the brick-wood structure, termites can't penetrate the firebrick or nest in the brick wall, so the ant nest is mostly located at the junction of the main beam with the thickest wood and the wall.

Urban concrete structure is complex, so the distribution of ant nests is also varied, often in the hollow sandwich wall, above the ceiling, near the water pipes in toilets, kitchens and bathrooms, gaps at the corner of the lintel, switches and both ends of the gold frame. In addition, underground nests also account for a considerable proportion, especially warehouses.

Essentials of eradication and treatment

1, powder poisoning method

The application technology has a great influence on the control effect. If the application site is improper, the dosage is too small or the powder is blocked, the expected control effect will not be achieved.

In order to avoid mistakes caused by improper use or other reasons, the efficacy test must be carried out after use. Because termites come and go frequently between nests, applying pesticides in the main nest can kill the whole termite population. The time from pesticide application to termite death is about 3-4 days in summer and 0/week in winter.

2. Trapping method

Trapping and killing methods include poison bait method and drug poison bait method, which are the main methods to kill termites at present.

3. Nest-digging method

In places where the drug source can't be solved, the method of digging holes is generally adopted. It is cold in winter, and domestic termites seldom go out when the temperature is lower than 10 degrees, and a large number of termites are concentrated in nests. At this time, digging a nest can get better results.

Second, eliminate termites.

Termites belong to the genus Reticulitermes, widely distributed in temperate and subtropical regions, and are the largest termites in China. So far, more than 100 books have been subscribed. It is a civil amphibian, scattered and does not build big nests, so it is called termites.

Scattered termites mainly harm the wooden components of houses and some cash crops. The discovered host plants are cassava, sunflower, persimmon, peach, willow, poplar, cypress, Broussonetia papyrifera, white dried layer and so on. As far as the characteristics of houses are concerned, termites with yellow breasts eat wood close to the ground, such as floors, doorframes, stair feet and column feet. So termites in Zhejiang don't climb buildings. Reticulitermes nigricans and Reticulitermes nigricans can corrode the top floor of buildings.

Essentials of eradication and treatment

1, check the ant damage very carefully. It is necessary not only to check the wooden components that have been found to be harmful, but also to carefully check the parts where no ants are found, so as not to let those wooden components hiding ants escape the net.

2. Grasp the application opportunity. The colony of Reticulitermes flavipectus often appears in rainy days in February and March, when the weather suddenly turns fine, the temperature rises rapidly to above 20 degrees (the first temperature rise in early spring), and the air pressure drops to 10 134Pa, generally at 106 1 Pa. In an area, it is generally divided into 2~4 groups a year, and it is better to apply the medicine after the first group 10 day to the last group, and the effect of applying the medicine on the same day is the best.

3. Choose the best place to apply.

4, daub should be deep, uniform and scattered.

5. Review the following year and apply continuously. Because there are many termite groups in a certain area, some of them have no grouped holes and signs of harm in that year, so they are easy to be left behind when applying pesticides.

Third, control termites piled in the sand.

Sand-piling termites belong to the family Termitotidae, belonging to the family Termitotidae. There are 9 species in China, distributed in the area south of 28 degrees north latitude. It has been found in Taiwan Province, Fujian, Zhejiang, Guangdong, Guangxi, Yunnan, Guizhou and Sichuan in China. The main hazards of sand termites are internal wooden components and wild trees and fruit trees. The found parasitic plants are litchi, coconut, banyan, maple, ruojun and Lagerstroemia indica.

Four, termite control, control points

1. fumigation: this is an important method to control sand termites. Fumigating agents must undergo special technical training. Staff should wear gas masks. For wooden furniture corroded by sand termites, small ones can be fumigated in fumigation room or fumigation box. The doors and windows of the fumigation room must be sealed with kraft paper, and the fumigated articles can also be covered with plastic film, and sand should be pressed around to prevent air leakage.

2. High-temperature termite control method: Termites piling sand will die in a few hours at a high temperature above 60 degrees. Therefore, using various methods to generate high temperature and treat rotten wood can prevent and control this kind of termites. Furniture corroded by sand termites can effectively kill termites if it is treated at 65℃ for 65,438+0 hours and 30 minutes or at 60℃ for 4 hours.

3. Soil treatment method: Because termites mostly penetrate the soil and enter the house. Therefore, it is necessary to treat the soil and establish toxic soil areas.

4. Wood treatment method: Wood parts of houses, such as beams, columns or slabs, which are in direct or indirect contact with the underground, must be treated.

5. Cleaning treatment method: In the place where termites have corroded, holes can be drilled and termites can be injected for mass killing. Other places such as wood surface, soil and building foundation must be thoroughly treated.
