What if there are moths at home? This insect is parasitic on the angle wood of logs and belongs to an entrained wood pest. Although it is less harmful and destructive than termites, it can still eat through hard hardwood floors and furniture. What if there are moths at home?

What if there are mealybugs at home? 1 First of all, why are there mealybugs at home?

The main reason for the damage of bark beetles is that they are carried by building materials for decoration, especially joists with wooden floors, furniture linings and partitions, which are the main transmission routes of bark beetles' adults or eggs. At the same time, we also found that the finished wood floor also carried adults. Pest control companies suggest that these moth pests grow on cellulose, starch and sugar in building materials after they enter the house with building materials, and they hatch, harm and gradually spread under suitable environment and temperature.

Second, the species of the mealybug and the performance of its harm

Moths that harm home improvement building materials mainly belong to two families: (1) mealybugs. The adult is about 3 mm long, the diameter of the damage hole is about 1 ~ 2 mm, and a lot of powder is discharged every day during the damage period. (2) Scale family, the adult is about 5 mm long, the hole diameter is about 3 mm, and there is no powder.

Third, the family control methods of mealybug

1, the preventive methods for decorating building materials are:

High-temperature method: Pest control company advises residents to use steam high-temperature degreasing method when degreasing building materials, which can not only degrease building materials, but also effectively kill moth adults and eggs, killing two birds with one stone.

Chemical control method: For joists used for floor laying, before floor laying, the pest control company suggests spraying or brushing pyrethroid pesticides, and building materials used for furniture and wallboard lining should be piled up in a unified way and sprayed with pyrethroid pesticides. Through the prevention of the above methods, the spread of moths can be basically controlled.

2. Moth control methods in residents' homes:

Selection of pyrethroid insecticides: direct injection of harmful parts with syringes can play a good role in contact killing and stomach toxicity to moths. If the hole density in the dangerous area is high, you can directly use the method of brushing. The pest control company reminds you to do a good job in the safe use of drugs in residents' homes.

What if there are mealybugs at home? How to kill a small mealybug?

preventive measure

(1) Strengthen quarantine work. It is forbidden to transport and carry pests and diseases. If trees with pests are found, they should be treated or peeled with chemicals in time to prevent the spread.

(2) Strengthen the technical measures of afforestation: suitable for the site and trees, rationally plan the afforestation site, improve the seeds and seedlings, and select tree species (varieties) with strong stress resistance; Create mixed coniferous and broad-leaved forests, intensively manage and strengthen tending: transform poor-growing stands by closing hillsides to facilitate afforestation; Age-appropriate cutting and reasonable thinning;

The roots should be cut low and peeled, and the top trees and branches with skins should be cleaned in time to keep the forest land clean; Strictly prevent forest fires and deforestation, and promptly remove fallen trees, broken trees and dead trees in the forest; Clean up the forest farm in advance and cut down low-growth trees and weak trees; The timber yard should be far away from the stands, and scientific management should be implemented to form a complete set of working systems for afforestation, logging, storage and transportation in forest areas.

(3) Coordination of mining, transportation and storage: it is forbidden to store logs with skins in summer cutting areas; Expanding

Logs and stumps cut down by Dalinban Line shall not stay in the forest for the summer without peeling; All newly cut logs must be transported out of the forest; Logs must be sorted or peeled in the log yard; Small-diameter trees cut from artificial young forests should also be transported out of the forest in time; Forest farms should also stay away from forest stands; Coordinate collection, transportation and storage to avoid the loss of pests in all production links.

(4) Biological control: The purpose is to strengthen the role of natural enemies. There are many kinds of natural enemies of bark beetles, including nematodes, mites, parasitic bees, flies, predatory insects and birds. For example, there are 7 species of parasitic wasps (cocoon bees and golden bees) on Dendroctonus armandii, which play a considerable role in controlling the occurrence of Dendroctonus armandii. We should strengthen the role of local dominant natural enemies and create favorable ecological conditions for them; Abuse of pesticides is strictly prohibited in the forest to avoid killing natural enemies.

Treatment measures

(1) Cutting pests: The pests found in monitoring and forecasting should be included in the cutting plan first, and sanitary selective cutting (clear cutting) measures should be taken. First, the dead trees and new dead trees that pose the greatest threat to the stand are cut down, and the local pioneer species and dominant species are the main targets, depending on the order in which they fly to invade the new host, usually before winter or in April of the following spring.

Adopt the method of encirclement and suppression, from light to heavy, from low to high, from sunny slope to shady slope, from forest edge to forest. The cut pest wood should be shipped out in time, or peeled or treated with drugs. After sanitary logging, carefully clean up the forest farm; It is necessary to select suitable tree species for replanting in the gap between sparse forest and skylight after sanitary selective cutting, which complicates the forest phase and increases the insect resistance of the forest itself.

(2) Bait wood trapping and killing: On the basis of cutting down pest trees, when the overall environmental sanitation of the stand is good and the insect plant rate is less than 20 plants/plant, bait wood can be set to trap and kill the remaining individuals. The method is to cut down a small number of weak trees as bait trees before the invasion of dominant species or pioneer species, and determine the setting method of bait trees according to the control objects (that is, whether to use original strips or logs and whether to add mats below them). The suitable bait number of 800m2 is 1 ~ 2.

Set 1 batch in March-April and June respectively. When a large number of new sub-tunnels appear and larvae have not yet pupated, bait trees should be stripped from June to July-August to eliminate larvae. Spraying 1%α- pinene on the bait wood can improve the trapping effect by 1 ~ 2.5 times.

(3) Chemical control: during the peak period of aerial invasion of overwintering adults (from late May to early July, depending on the location), 80% dichlorvos EC, 40% omethoate EC or 80% phoxim EC 0/00 ~ 200 times of/kloc-was used to spray the stumps to kill the adults; According to the characteristics that Tomicus piniperda overwinters in the bark of the northern root neck, in early spring and April, the root neck soil layer can be dug to 10cm, and 2% chlorpyrifos powder or 5% carbaryl powder can be deeply applied at the dosage of 10g per plant, and then the soil can be firmly covered, with an excellent insecticidal rate of 98%.

In order to control Tomicus piniperda, 3% carbofuran granules were applied to the roots of weak woody plants in the forest, and 200g or 2 ml of 40% omethoate emulsifiable concentrate or 40% SN~85 1+0 insecticide was punched at the base of the trunk to prevent adults from gathering and boring. The use of garden medicine-moth-inserted net bottle has obvious effect on the treatment of bark beetles, longicorn beetles and Trichogramma. , green and environmentally friendly.

(4) Fumigation treatment of logs: agricultural film with a thickness of 0. 12mm is selected, tents with corresponding sizes are bonded with adhesive according to the size of logs, and covered on logs, and the edges of the film are compacted with soil along the ditches of logs to prevent chemicals from escaping after gasification. Open a hole in the film above the woodpile, and add methyl bromide (CH3BR) 10 ~ 20g/m3 or aluminum phosphide 3g/m3. , or sulfuryl fluoride (F2O2S) 30g/m3, sealed and fumigated for 2 ~ 3 days and nights. This method can not only kill bark beetles, but also treat the larvae of longicorn beetles that have eaten xylem.

(5) Attractant: including aggregate pheromone crude extract and artificial attractant of Dendrolimus punctatus; The latter can also trap and kill bark beetles. The research and application of aggregation pheromones and attractants is a field worthy of vigorous development, and the related research at home and abroad is in the ascendant, playing an increasingly important role in the control of bark beetles.

What if there are moths at home? 3 1. Scatter diatomite in the cupboard and put it in a dark place. Diatomite is made of crushed fossil materials, and each particle has a sharp edge, which can pierce the exoskeleton of insects and can be fatal, but harmless to people or pets.

2. Another natural material can kill moths and moth eggs. Sprinkle boric acid along the bottom of the cabinet, under the bathtub, and other places with insect-eaten marks. Be careful not to get it on yourself because boric acid is toxic and harmful to the lungs. Remember to avoid using boric acid in places where pets haunt.

3. Chemical insecticide spray containing liquid pyrethrins. This chemical can kill moths and spray it on the bottom and crevices of cabinets and other places where you think there are moths. Remember not to spray it on the cabinet or other places near food, and don't spray it where children and pets come into contact, because it is toxic.

Moth, a biting insect. It is also a metaphor for the bad guys who endanger the collective interests. Beetles spread all over the northern and southern provinces of China, endangering Pinus massoniana, Pinus densiflora, Pinus armandii, Pinus tabulaeformis and Pinus sylvestris var. mongolica. Mongolian pine and black pine. Use adults and larvae to destroy twigs, branches or cut trees of pine trees. Any damaged tip is easily broken by the wind.

Extended data

1, cut down the damaged trees, reduce the harm of pests, and immediately cut down the severely damaged weak trees or dead trees for necessary pest control treatment.

Treatment methods: First, uproot the whole tree; The second is to remove the lateral branches and roots and burn them; The third is to cut the trunk into 3-meter-long blocks; The fourth is to dig a pit 1 m deep, 2 m wide and 4 m long; Fifth, put the trunk (segment) in and fumigate it with aluminum phosphide 3g/m3 (sealed with plastic film with a thickness of 0. 12mm) (3-5 days); Fifth, take out the tree segments, scrape off the bark and burn it.

2. Chemical control of trunk: For slightly damaged Pinus tabulaeformis, the method of spraying pesticides around the trunk and branches (from top to bottom) is adopted. The pesticide is a strong systemic agent such as 40% omethoate or toxic zinc, and a penetrating agent is added at the same time, and the concentration is 100-200 times. Spraying time is before 9: 00 am and after 5: 30 pm. Don't spray when it's windy and rainy, but do it at the same time. Do a good job of antivirus when spraying drugs.

3. Spraying chemicals at the base of the trunk for prevention and control, removing weeds in the range of 0.5-0.8m around the base of the trunk, spraying wettable powder such as phoxim mixed with phosphorus, and shallow turning the tree tray to kill the overwintering adults.
