Sulfuryl fluoride (SF) is a fumigant used to eliminate drywood termites (DWT: Kalotermitidae; Froggatt) and other structural pests. Because of its global warming potential, it has been suggested that SF be restricted as a greenhouse gas (GHG). We present an economic model to assess the net social cost of restricting SF. We consider 3 approaches to address DWT control- no treatment, allowing SF fumigation and localized treatments, and only local treatment. Each approach generates private and public benefits and costs. We estimate that the annual damage and home equity loss by DWT in California is US$4.5–16.8 billion without treatment. If fumigation is used on 20% of the houses and local treatments on the others, the combined social cost of treatment, damage, and GHG emissions are between US$1–US$2 billion annually. The annual cost of local treatments only would be between US$3.2 and US$4.9 billion. If the application of SF is severely restricted or banned, the social costs will increase between US$1.43 and US$4.31 billion annually. The implied cost per ton of CO2 eliminated is between US$624 and US$1,465, much above the price range of CO2 in other applications. The restriction/ban has significant equity and environmental effects, impacting low-income individuals living in rented properties and replacing damaged wood in housing will increase GHG emissions. We further recommend the continued use of SF until a comparable whole-structure alternative is developed that fits the parameters of our model.

评估禁用杀虫剂的影响的经济框架，以及对加利福尼亚州干木白蚁（蜚蠊目：Kalotermitidae）使用硫酰氟的影响

硫酰氟 (SF) 是一种熏蒸剂，用于消灭干木白蚁（DWT：Kalotermitidae；Froggatt）和其他结构性害虫。由于其可能导致全球变暖，有人建议将 SF 作为温室气体 (GHG) 进行限制。我们提出了一个经济模型来评估限制SF的净社会成本。我们考虑了 3 种方法来解决 DWT 控制问题——不进行治疗、允许 SF 熏蒸和局部治疗以及仅进行局部治疗。每种方法都会产生私人和公共利益和成本。我们估计，如果不进行治疗，加州 DWT 每年造成的损失和房屋净值损失为 4.5 至 168 亿美元。如果对 20% 的房屋进行熏蒸处理，对其他房屋进行局部处理，则处理、损害和温室气体排放的综合社会成本每年将在 1 至 20 亿美元之间。仅局部治疗每年的费用就在 3.2 美元至 49 亿美元之间。如果严格限制或禁止SF的应用，社会成本每年将增加1.43美元至43.1亿美元。每消除一吨二氧化碳的隐含成本在 624 美元至 1,465 美元之间，远高于其他应用中二氧化碳的价格范围。该限制/禁令具有重大的公平和环境影响，影响居住在出租房屋中的低收入个人，更换房屋中损坏的木材将增加温室气体排放。我们进一步建议继续使用 SF，直到开发出适合我们模型参数的可比较的整体结构替代方案。
