I. Bed bug hazards

The bedbug sucks blood at night and disturbs people, making them unable to sleep. Because saliva is injected into the human body when biting, local swelling and itching can occur in people with higher skin sensitivity. In Africa, there are reports of anemia, heart disease and colds caused by bedbug bloodsucking. Bed bugs have long been suspected of spreading diseases. Although bedbugs can be infected with many pathogens by experimental methods, it has not been proved that bedbugs can transmit diseases under natural conditions.

Bedbug lumbar injuries are easy to occur in exposed areas, such as face, neck, limbs, etc. If caused by bedbugs, they can occur in clothes covered areas. Skin lesions can be dispersed or clustered. They can be seen as spinning red pimples of the size of mung beans to peanuts. Bulls often appear on the top of pimples, and bullae can be seen in a few cases. Individual sensitive person, bite can appear a large area of red and swollen spots, if occurs in the eyelid, hand, foot back, scrotum, prepuce, lip and other tissue loose parts, then edema is more obvious. Scratching often causes local erosion and secondary infection. Conscious and obvious itching, serious even affect daily life. After one to two weeks, the lesion gradually subsided, leaving brown pigmentation locally. This pigmentation is temporary and can subside by itself after half a year. The disease is prone to recurrence. New rashes often occur in batches and repeatedly. Generally no fever, fatigue and other systemic symptoms.

II. Bed bug control

Do a good job of household hygiene, block furniture, walls, floors, especially the gap between beds and chairs to control bedbug breeding areas. At the same time, the simplest way to kill bedbugs is to blanch them with boiling water. Professional companies can also be invited to use various pesticides to kill them. When traveling or moving bedpanels and furniture, we should carefully check luggage and old furniture to avoid the spread of bedbugs.

1. INVESTIGATION OF INJURY

Bed bugs are found in feces, bedbug bloodstains, live bedbugs, etc. The needle-picking method combined with visual method is used to check the bedbug infestation indications of suspicious habitats (brown shed, bedstead, mirror line, panel wall crevice, tables, chairs, sofas, etc.) and the bedbug odor can be smelled seriously.

2. Environmental prevention and control

The purpose of environmental control is to eradicate breeding conditions, that is, to rectify indoor hygiene, remove debris, to block bedbug-prone crevices such as bedboards, walls and Brown shed with lime or putty, and to tear down and burn the wallpaper where bedbugs breed.

3. Physical prevention and control

(1) Manual capture: knock on bedstead, bedplate, Kang mat, straw mat, etc., to shock and kill bedbugs, or pick out the bedbugs in the cracks with needles and wires, to kill them.

(2) Boiling water ironing: bedbugs do not bear high temperature, can use boiling water to blanch all eggs and adults, bedstead, bedplate and other appliances with bedbug breeding can be moved outdoors, with boiling water pot mouth aiming at the gap, slowly moving ironing, must make the gap to reach high temperature, in order to blanch bedbugs and their eggs, clothes and mosquito nets breeding bedbugs, can be soaked in boiling water.

(3) Solar exposure: For clothes that cannot be soaked in boiling water, they can be exposed to intense sunlight for 1-4 hours and turned over to kill bedbugs because of high temperature sunning or crawling out.

(4) Prevention of spread: In bedbug-infested rooms, the movement of luggage and furniture (relocation or sale) must be strictly checked and handled to prevent the spread of bedbugs.

4. Chemical control

According to the requirement of Shenzhen Aiwei Medication Association, after several years of practice and summary, the company has sorted out a set of professional methods for bedbug control. The characteristics of its medicines are as follows:

(1) High efficiency: One treatment can basically eliminate bedbugs.

(2) Long-lasting effect: It can maintain the efficacy for several months at a time, so it can not only kill the adult nymphs in the environment, but also the newly hatched nymphs from the treated eggs and the newly invaded bedbugs from the outside world.

(3) easy to use: no need for large spray tools, only manual or electric low volume sprays are partially retained for spraying.

(4) Safer: The toxicity of this drug is 3 times less than that of dichlorvos, and the coating method is not easy to be touched.
