以下是居民们想知道的乐虎网在社区喷洒灭蚊喷雾的10件事. 重要的是要注意,这些常见问题的具体答案可能会因你所在社区使用的灭蚊产品而异. But generally:
在社区范围内,使用安装在卡车或全地形车后部的超低体积(ULV)喷雾设备进行成蚊控制治疗. ULV sprayers turn a liquid mosquito control product into an ultra-fine spray cloud or mist, made up of tiny droplets. 这些飞沫在喷洒时随风在空气中移动,与飞行的成年蚊子接触.
In order to be effective, the droplets need to make physical contact with the flying mosquito, 所以紫外线照射通常在当地蚊子最活跃的黄昏或黎明开始. 它们没有任何残留效应——它们只在治疗时起作用,迅速减少成年蚊子的数量. Once applied, the product begins to break down rapidly and dissipates 5 to 30 minutes later, depending on the formulation and weather conditions.
我们理解很多居民在日常生活中对农药接触的担忧. And, we know many individuals are generally sensitive to chemicals, whether they’re from a perfume or a pesticide, and take steps to limit exposure whenever possible. However, mosquito control treatments, applied correctly, using EPA-registered products, 不会伤害人类或宠物,是保护公众免受蚊媒疾病侵害的重要做法. That said, we do offer residents the ability to sign-up for advance notification of scheduled applications, so they can plan accordingly.
Plants and garden beds do not need to be covered or harvested before a treatment. Just use the same practice that should be followed with grocery or market produce, and rinse with water and a mild detergent before consuming.
Leave the A/C on! 在喷雾处理期间,窗户也可以保持打开状态,但大多数居民更喜欢关闭窗户. Decades ago, these were common recommendations, but as application technology and product chemistries have evolved, this is no longer a necessary measure.
Insecticide applications are not one-size-fits-all, and spray treatments to reduce flying, biting, adult mosquito populations will not work on ticks. Why? Mosquitoes are flying; ticks are crawling; AND they are a completely different type of insect, with a very different body size. While the same product may be used for tick and mosquito control treatments, the application method and dose will be different. Applications for ticks need to be made at ground-level where they crawl, 而且使用的剂量明显高于控制成蚊喷洒所需的剂量.
(Ahh… you were waiting for this one!) This one gets tricky and can be very product-specific, but generally, the answer is, have no fear! 从美国疾病控制与预防中心下载这份情况说明书,详细介绍了喷雾剂的应用. While the EPA has determined that certain active ingredients in pesticides may be toxic to beneficial insects upon direct exposure, four key things reduce this risk for mosquito control applications:
喷洒蚊子和蜜蜂——这是另一个敏感问题,也是每个从事公共卫生蚊虫控制工作的人都非常重视的问题. Firstly, 保护其他有益昆虫的同样保护措施也适用于蜜蜂, 此外,还鼓励蚊虫控制项目与当地养蜂人保持透明的关系,并提前提供治疗通知. 也有很多由非常著名的学术机构发表的实地调查和研究, such as Louisiana State University, that demonstrate mosquito control applications, when conducted according to all label guidelines, do not present a material risk to pollinators. For example, this article summarizing field research conducted by LSU demonstrates that ULV treatments for mosquito control do not harm honey bees, even in cases of direct spray applications.
Less – and quieter – is better! ULV spray technology has evolved quite a bit since the days of DDT fogger treatments. Modern chemistries, more advanced, quieter spray equipment, 多变的天气条件意味着雾云并不总是可见或可闻,但这并不意味着它不起作用!
每辆乐虎网的喷雾车都配备了两项技术,以确保喷雾的有效性和安全性. First is a monitoring system called SmartFlow. 该设备可根据车辆速度的变化调节喷雾量,以确保均匀的处理率. So, whether we are driving 5 or 15 mph, the right application rate is being dispersed. The second technology used is called GeoTab, which is a GPS-based application that tracks vehicle locations, vehicle speeds, and spray activity (on/off) in real-time.
喷雾治疗的时机总是与我们所服务的社区密切协调,并取决于他们的蚊子控制计划和预算的设计. To determine spray requirements, we look at population and disease monitoring data from surveillance traps in the local area, and combine it with insights from environmental conditions, predictive software, resident calls, and resource availability to time adult mosquito treatments to deliver the most relief.
Last but not least, ULV spray treatments followed by rain are usually still effective, as long as there were adult mosquitoes in flight at the time of treatment. However, 在植物叶片上喷洒屏障处理的持久力可能会受到天气条件的影响.
