What to do if the roof is a raw worm of wood 20

In hot weather.

At noon, use 500 times liquid dichlorvos.

After spraying, the room is sealed for 30 minutes, and all of them can be killed. Because dichlorvos has a strong fumigation effect, it can make all the insects in the cracks of the wood fumigate to death.

It can be sprayed or smoked with sulfur smoke in unmanned conditions.

First, the method of deworming:

1. Use an appropriate amount of sharp pepper or Sichuan pepper, mash it into the end, stuff it into the moth hole, and flush it with boiling water, which has the effect of killing insects and preventing the spread of insects.

2. Mix well with fire water and a small amount of insecticidal water, and drip into the cavity to kill the moth.

Second, the method of mothproofing:

1 Paint treatment. For some corners that have not yet been damaged, paint such as tung oil, shellac paint or varnish is used to brush the surface of the wood, which can isolate the moth from the air and achieve the purpose of moth-proofing. Note that when painting, the front and back sides and the inner walls of the wood.

should be evenly painted.

2 Pharmacy treatment. When the wood is infested by insects, dichlorvos and water can be used in a ratio of 1 5 to prepare the solution, spray it with a sprayer, let the liquid infiltrate into the wood, spray 3 times 5 times in a row, after 8 hours, it can kill all the moths. Pass.

After that, the wood is washed and dried with clean water.

3 Rub the wood with diesel fuel on a sunny day, put the wood that has been eaten by insects in the sunny place, and paint all the wood with a brush or cotton yarn dipped in diesel oil1

All over. Dry for two or three hours and then apply it once, and then dry it again, until you see the moth dead at the mouth of the hole. Then wash and dry with laundry detergent.

Dry. 4. After the wood is bought, soak it with 3% sodium fluoride to prevent insects forever.

5. Brush it with colorless varnish, which can not only increase the luminosity of the wood, but also kill insects. This is because after varnishing, the wood is cut off from the air, and the borers cannot survive.

Wood insects on the house are caused by termites, and avermectin and ivermectin derivatives are mostly used.

Abamectin was first used for the control of parasitic nematodes. In the laboratory test, the use of avermectin with a concentration of 20 mg kg can eliminate termites, 4 5 days after the use of the drug is the peak period of termite death, the mortality rate is 32%, the dose of each termite contact with G will make the termites appear semi-lethal, will not pollute the natural environment.

Ivermectin is used in the control test of milk termites and xantes in Taiwan, and when the solution concentration reaches 25mg L, it has a good insecticidal effect. When the concentration is 100 mg l, the mortality rate of termites can reach 100% after 24 hours.

This test is rarely used in the field, and must be used at a higher dose and sealed to effectively penetrate termites, and the effective concentration will be much higher than under indoor test conditions.

Termite hazards:

Termites have a wide range of damages, such as houses, warehouses, railways, sleepers, car boxes, bridges, ships, poles, wires and cables, clothes, books, paper, documents, bills, banknotes, rubber, plastics, metals, reservoir dams, agricultural and forestry crops, etc., and almost all kinds of items have direct or indirect relationships.

When termites are seriously damaged, the affected rural houses are almost ten rooms and nine moths. River embankments, also due to termite infestation, often burst into disasters, destroying a large number of lives and property.

China is one of the countries seriously affected by termites. There are more than 470 species of termites known in China, among which the most common main species that cause serious damage are Taiwan milk termites, yellow-breasted scattered termites, black-breasted scattered termites, black-winged soil termites, yellow-winged large termites, large soil termites, large termites, Qibei scattered termites, etc.

There are the following ways to deal with it:

Paint treatment. For some corners that have not yet been infested by insects, paint such as tung oil, shellac paint or varnish is used to brush the surface of the wood, which can isolate the moth from the air and achieve the purpose of moth-proofing. It should be noted that when painting, the entire wood should be evenly painted.

2 Pharmacy treatment. Can be used dichlorvos and water in the ratio of 1 5 to prepare the liquid medicine, with a sprayer to spray comprehensively, so that the liquid can penetrate into the wood, to spray 3 times 5 times in a row, after 8 hours, can kill all the moths. After that, the wood is washed and dried with water.

3 Rub with diesel. On sunny days, paint all the wood once with a brush or cotton yarn dipped in diesel. Dry for two or three hours and then apply it once, and then dry it again, until you see the moth dead at the mouth of the hole. Then wash and dry with laundry detergent.

Answer: Soak a high concentration of dichlorvos in cotton, find a wormhole and stuff it in, stuff it as deep as possible, or use a needle for injection to inject medicine into it, and then use a brush to dip dichlorvos to brush the beams of the house, brush it several times! Let dichlorvos moisturize the wood enough.

Paint method: use paint to oil the board, isolate the air, and then the moth will hang, this method is easy to partially isolate the air is not complete, the sealing degree is not high, you need to pay attention to the oil paint, and the paint smell is difficult to eliminate.

Insecticide: Find the moth-eaten area, clean the wood powder, spray the insecticide for a few days, then wash it and dry it in the sun.

If it is termites, things are more troublesome and should be dealt with by experts to avoid large losses; If it is a longhorn beetle, in general, the number of occurrences is not much, the sound it makes, it is easy to find out the channel of decay, drill with a drill, and sometimes use iron wire to hook out the larvae of the longhorn beetle, if you can't find the larvae, you can put crushed camphor, or camphor oil into the hole, and seal it with wax on the outside;

If it is a mealty borer, then in the part where the borer is found, drill some small holes with a small drill, inject camphor oil, seal the outside with plastic, and wait for the borer to die, and then paint to restore.

You can put some insect repellent medicine, preferably in the sun.

1. Paint treatment method: This method is mainly used to prevent moth, in short, it is to use tung oil, shellac paint or varnish and other coatings to coat the surface of the wood where insects have not yet grown, so that the insects can be effectively isolated from the outside air, and the purpose of moths is achieved.

2. Medicinal treatment method: This method is very simple, that is, when you find that the wood is eaten by insects, buy some dichlorvos, and then mix it with water in a ratio of 1 to 5. Then use the upper sprayer to spray all the potion into the wood as much as possible, and this is not done by spraying only once, you need to spray 3 to 5 times in a row, and after a few hours, you can probably kill all the moths.

3. Diesel erasing method: If you want to use this method, you have to look at the weather at that time, because this method needs to be carried out in good sunny weather. First, put the wood that has been eaten by insects in a sunny place, and then paint all the wood with a brush or cloth dipped in diesel.

Then it is exposed to the sun, and after two or three hours, it is coated with a layer of diesel, and it is exposed again until you see the moth dead at the mouth of the hole.

Summary. Deworming method.

After that, the wood is washed and dried with water.

Dichlorvos) drops into the moth-eaten holes, and can also be pounded with sharp peppers or peppercorns, and stuffed into the moth-eaten holes. Method.

3. Apply paraffin oil to the moth-eaten area for 10 consecutive days. For some corners that have not yet been damaged, paint such as tung oil, shellac paint or varnish should be used to brush the surface of the wood, which can isolate the moth from the air and achieve the purpose of preventing moths.

There are insect eyes on the rafters on the roof of my house, and there are grains the size of rice grains on the corresponding ground, what are the termites? Worms, yes.

The roof beams have been eaten by bugs, and that would be a very dangerous thing. Because this kind of insect that can burth small holes in wood is termites. Termites feed exclusively on wood and reproduce extremely quickly.

Termite bridges are active in swarms. On the surface, there is only a small moth-eaten hole on the roof, but in fact, the roof beam has been eaten empty by termites. As long as there is a thick snow on the roof or other loads, the roof beams and pillars may be broken and collapsed, causing ** accidents.

So termites must be exterminated.

My home is in Qinghe County, Xingtai City, Hebei Province, and you can find termite exterminators in 58.com.
