控制蚊子和其他疾病媒介的公共卫生计划还有一个额外的好处，那就是减少居民接触害虫的机会。我们对威斯康星州麦迪逊市的房主进行了调查，并使用经济评估方法和规定选择实验来衡量在当前和增加的西尼罗河病毒（WNV）风险水平下控制传播西尼罗病毒（WNV）和滋扰蚊子的支付意愿（WTP）。在目前的西尼罗河病毒风险水平（大约 25 万分之一）下，麦迪逊调查受访者平均不愿意为仅针对传播西尼罗河的蚊子的计划付费（支付意愿 = -$21, 95% [CI -$63, $20]），而减少滋扰蚊子的支付意愿相当可观（支付意愿 = $147, 95% [CI $109, 186 美元]）。随着西尼罗河病毒风险的增加，控制携带疾病的蚊子的支付意愿也增加（支付意愿 = 158 美元；在最高风险水平下，95% CI [111 美元，206 美元]），但控制滋扰的支付意愿仍然很高（支付意愿 = 108 美元；95% 置信区间 [78 美元，138 美元]）。在我们样本的业主中，就受访者的防蚊需求而言，“滋扰因素”比“疾病因素”更重要。
Public health programs that control mosquitoes and other disease vectors have the added benefit of reducing residents' exposure to pest insects. We surveyed homeowners in Madison, Wisconsin, and used an economic valuation method, stated-choice experiments, to measure willingness to pay (WTP) for control of West Nile virus (WNV)-transmitting and nuisance mosquitoes under current and increased levels of WNV risk. Under current WNV risk levels (approximately 1 in 250,000), the average Madison survey respondent was not willing to pay for programs that targeted West Nile-transmitting mosquitoes only (WTP = -$21, 95% [CI -$63, $20]), while WTP for a reduction in nuisance mosquitoes was substantial (WTP = $147, 95% [CI $109, $186]). As the risk of WNV was increased, WTP for control of disease-carrying mosquitoes also increased (WTP = $158; 95% CI [$111, $206] at the highest risk level), but WTP for nuisance control remained high (WTP = $108; 95% CI [$78, $138]). Among homeowners in our sample, the "nuisance factor" was more important than the "disease factor" in terms of respondents' demand for mosquito control.
