How to prevent termites?

Prevention and control: Don't panic when termites appear, and don't use scalding water, cement plugging, mosquito killing drugs and other methods. These methods can't solve the fundamental problem. Because of this, first, it destroys the scene and is not conducive to professional analysis; Second, after self-treatment, the live termites that have not been eliminated are diverted, causing greater harm. Therefore, once termites are found, it is necessary to contact the professional units for the prevention and control of white mosquitoes in time. Hazard: Termites mainly eat cellulose. They can eat everything except glass and ceramics. The harm of termites is extremely extensive. Termites can eat wood into pieces, and the formic acid secreted by termites can corrode steel bars and concrete, easily bite through the cement floor, further loosen the reinforced concrete structure, lose its firmness and integrity, and endanger the safety of houses. There are many ways to control termites, which should be controlled according to their characteristics. When termites are found, they should keep the signs of termites and the objects eaten by termites, and never clean up the scene. First of all, the site must be inspected clearly, and the termites' nests must be judged according to the signs of termites. 1, the method of checking termites, and determining the position of termite nests according to the signs of termite exposure. Usually, the signs of termites are ant passages, excrement, nest holes, air holes and so on. And it is necessary to judge according to the number of termites in these signs. The ant path of termites is thick or thin. Pick the thicker end of the ant path with a rose knife, and the soldier ants of termites, especially those with a large number, are closer to the direction of the ant nest. Feces are the nesting materials of termites, and they are generally brown. The color of feces varies with the diet of termites. Pick up shit with a rose knife or insert it into a hole to see the number of soldier ants in the hole. If the soldiers are heavily guarded, the hole will be blocked soon after a period of time, and this place may be close to or just an ant nest. Stomata are the windows of termites' nests. In places where termites are numerous and dense, air holes are needed for ventilation or temperature adjustment. Air holes are as small as needle eyes and as big as beans, and there is no certain arrangement law. Pick up the blowhole, a large number of soldiers will climb out to guard the blowhole, and workers will immediately block the blowhole. The grouping holes are generally above the ant nest and close to it. The grouping holes are slightly larger than the air holes. In the season of "parting", breeding ants with long wings are waiting to fly out of the waiting room. If disturbed, long-winged breeding ants will fly out immediately. It is easier to find the ant nest by using group holes or air holes. 2. Termite control methods After detailed inspection, an ant nest was found according to the inspection situation, and it was found that the termite nest could be controlled by methods such as digging the nest, killing drugs, trapping and killing. Different methods are used to control termites according to different situations. General tree nests, wall nests, especially mud brick wall nests, shallow tree head nests or underground nests can be dug, and it is best to dig nests in winter, because cold weather will freeze the remaining termites after digging nests, so that termites can be completely eliminated. It is better to apply some termite medicine after digging the nest. Drug killing method is to spray termites with termites' drugs in the signs of eating, so that termites can stick to their bodies with termite powder. Every day, termites transport food back to their nests to feed other termites. When termites with powder on their bodies return to their nests, other termites find that there are unclean things on their bodies, and they will use mouthparts to help clean them up. At this time, the powder will be passed to other termites, resulting in the poisoning death of the whole nest of termites. The main components of termite powder we use now are arsenious acid, mirex and so on. They are all chronic drugs. Generally, termites are all poisoned one week or one month after application. Drug killing is the simplest way to kill termites, as long as you insert a few holes with a rose knife and spray a proper amount of powder in places where there are many termites, such as ant passages, feces, stomata and grouped holes. Then check whether all termites are poisoned to death after one week or one month. There are two methods of trapping and killing: drug trapping and light trapping. When termites are found but their nests can't be found, or when they are known and can't be dug up, and when the number of termites is too small to be completely eliminated by drug killing, it is best to use trapping and killing. The trap box is made by nailing a box with wooden boards, preferably pine boards that termites like to eat, putting some wood blocks and shavings in the box, and then putting the wooden box where termites come out to lure termites out to eat and corrode the wooden box. After a period of time (half a month or a month), a large number of termites gather in wooden boxes to eat and corrode. At this time, the wooden box has formed a termite nest, and then coated with termite powder to make a large number of termites bring the powder into the nest. Light trapping is mainly used to deal with long-winged reproduction. When a large number of termite breeding ants fly in at night and pounce on the light, putting a pot of clear water under the light can reflect the light and drown the termites when they pounce on the water. At the same time, it is best to spray pesticides on the corners of rooms and the bottom of furniture to prevent some breeding ants from crawling into these places.
