At the level of vector density control, physical mosquito-killing devices show significant advantages. WHO data shows that when the density of female Aedes mosquitoes drops to less than 5 mosquitoes per 100 people, the risk of dengue fever transmission decreases by 92%. The three-band ultraviolet spectrum of Bug Zapper (with a main peak of 365nm) combined with bionic carbon dioxide release (200ml/min) has an attractive effect on mosquitoes that exceeds that of traditional single-spectrum devices by 138% (USDA 2023 control experiment). After the Ministry of Health of Malaysia deployed 1,000 similar devices in the dengue fever epidemic area, the proportion of Aedes aegypti mosquitoes in the captured samples reached 47.3% (including 4.7% of virus-carrying individuals), reducing the mosquito bite index in the local area from 29.6 times per person per night to 3.1 times, and the mosquito vector density attenuation rate reached 89.5%.
The core of blocking the virus transmission chain lies in the efficiency of eliminating pathogenic vectors. The incubation period of the Zika virus in mosquitoes is approximately 10 days, and the vector needs to be cleared before the virus spreads. The 1500V high-voltage grid response time of Bug Zapper is less than 0.02 seconds, the single discharge energy reaches 30mJ, and the instantaneous killing rate is 99.7% (sample size N=5000). Compared with the 78% mortality rate of chemical spraying, physical methods prevent the development of drug resistance – monitoring in Florida shows that after continuous use of pyrethroid insecticides for five years, the frequency of drug resistance genes in Aedes albopictus rose from 12% to 67%. A 2025 study in The Lancet showed that the incidence of dengue fever in communities using electric grids for mosquito control decreased by 47% compared with areas controlled by drugs (RR=0.53,95%CI 0.41-0.68).
The economic benefit model verifies the value of disease prevention and control. Statistics during the Zika virus outbreak in Brazil show that the medical expenditure for a single patient was approximately $23,000 (including treatment and productivity loss). And the community plan for deploying the Bug Zapper device:
• Initial investment: $40 per unit (covering a radius of 15 meters)
Operating cost: $0.03 per day (5W×10h×$0.1 per kilowatt-hour)
• Equipment density per thousand people: 22 units
Compared with the annual expenditure of $8.7 per person for chemical prevention and control, the cost of the physical solution is only $3.2 per person. The Senegal community Project has confirmed that for every $1 budget invested in mosquito control equipment, $17 in public health expenditure is saved (IRR=203%).
The environmental compatibility and comprehensive prevention and control have achieved remarkable results. Chemical pesticides cause the mortality rate of non-target organisms to reach 21% (such as a 17% reduction in bee populations), while physical methods have a nearly zero impact on the ecological environment. The Bug Zapper is equipped with an intelligent photosensitive sensor and automatically turns off 2 hours before sunrise (with an energy-saving rate of 38%). In the joint prevention and control of the Thailand-Cambodia border in 2024, the Bug Zapper network linked by the Internet of Things reduced the incidence of malaria from 15.3 cases per thousand people to 2.7 cases. Data regression analysis showed that the device density was significantly negatively correlated with the incidence rate (r=-0.91,P<0.001). The Africa Centres for Disease Control and Prevention plans to increase the penetration rate of such devices in epidemic areas to 60% by 2030, and it is expected to prevent 230,000 deaths from mosquito-borne diseases each year.
