The most effective measures to prevent and control mosquitoes are:
Removal or control of mosquito breeding sites (stagnant water)
The construction site is structurally complex due to its environment
It is very easy to produce mosquito breeding grounds
If not properly managed, mosquitoes can easily breed
The density of adult mosquitoes is too high
or periods of epidemics of mosquito-borne infectious diseases
It is necessary to start an emergency anti-mosquito operation
Adult mosquito eradication should be carried out in a timely manner
Different places on the construction site
What kind of mosquito repellent products are more appropriate?
Insecticidal aerosols
When adult mosquitoes are found in site offices, dormitories and other enclosed rooms, household hygiene insecticides should be used, such as commercially available insecticidal aerosols with certificate numbers (such as pyrethroids).
●Close doors and windows before application.
●The application method is operated in accordance with the instructions, generally: shake the aerosol can fully, hold the aerosol can up 30 degrees, press the valve to spray from the inside to the outside of the space, spray for about 10 to 15 seconds per 15 square meters of room or spray according to the dosage of the instructions.
●Focus on spraying all kinds of cabinets, beds, tables, under tables, under sofas, wall bases, and sundries.
●After the application of pesticides, the personnel leave, and then open the doors and windows for ventilation for 20 minutes after 0.5 to 1 hour before the personnel can enter the room.
Commercially available mosquito killer tablets
In the indoor or basement closed by the construction site, a mosquito control sheet can be used every 15 square meters according to the instruction manual, close the doors and windows after ignition, open the doors and windows after 0.5 to 1 hour, and ventilate for 20 minutes before personnel can enter the room.
Mosquito killer lamp
Mosquito killer lamps can be used in indoors, basements, stairwells, green belts and other environments where there is no one on the construction site.
● Drop off area
Mosquito control lamps should be placed in dark areas with a large number of adult mosquitoes to minimize mosquitoes being disturbed by other light sources and affecting the mosquito control effect.
● Opening time
1. The outdoor mosquito killer lamp can be turned on at dusk every day and turned off after dawn.
2. In basements and other lightless environments, mosquito killer lamps can be turned on for a long time.
●Precautions
1. Attention should be paid to the use of mosquito killer lamps, and try to avoid direct eye exposure to mosquito killer lamps for a long time to avoid damage to construction personnel.
2. Mosquito killer lamps, power grids or mosquito collectors should be cleaned regularly to avoid residues affecting the trapping effect.
Mosquito nets
For mosquito-borne infectious disease epidemic areas, the use of long-lasting mosquito nets that can effectively repel or even kill mosquitoes can not only isolate mosquitoes spatially, but also kill or repel mosquitoes through the insecticides they carry.
●Mosquito-repellent nets can be purchased directly, and if they are made by soaking or spraying with drugs, they must be operated by professionals.
●Commonly used agents are 1% deltamethrin suspension, 10% cis cypermethrin suspension, 2.5% cyhalothrin microencapsule, and 10% permethrin EC.
Kill adult mosquitoes in a large area
If the site needs to kill adult mosquitoes in a large area, it is recommended to hire a professional pest control company to carry out the work.
●The chemical method of rapid killing of adult mosquitoes mainly includes ultra-low volume spray method and hot aerosol method.
●The methods of continuous retention and killing of adult mosquitoes by chemical method include indoor residual spraying method and outdoor hedge technology spraying method.
Safety precautions for drug use
●Hygienic insecticides must be selected within the validity period of the pesticide registration certificate.
●The drugs recommended in this article are all sanitary pesticides with low toxicity to humans and animals, but it is still necessary to pay attention to safety, and the drugs should be kept in a place that is not easily accessible to children to avoid children touching or ingesting them.
●Wash your hands after touching drugs.
