The Indonesian city of Probolinggo is taking an unconventional approach to combatting a rise in dengue fever cases: encouraging residents to plant lavender. With 36 cases reported in the first two months of 2026, and a concerningly low percentage of homes currently free of mosquito breeding sites, local authorities are hoping the fragrant herb will offer a natural deterrent alongside traditional mosquito control measures. This initiative reflects a growing global interest in exploring sustainable and community-based solutions to public health challenges.
Dengue fever, a mosquito-borne viral infection, remains a significant public health concern in many tropical and subtropical regions. Symptoms range from mild fever to severe flu-like illness, and in some cases, can develop into life-threatening dengue hemorrhagic fever. The Aedes aegypti mosquito is the primary vector responsible for transmitting the virus, breeding in stagnant water around human dwellings. Effective control relies on eliminating these breeding sites and protecting individuals from mosquito bites. The city’s proactive stance comes after a period of fluctuating case numbers, with 326 cases and four fatalities reported throughout 2025, a decrease from the 490 cases and six deaths recorded in 2024. However, officials emphasize that complacency is not an option, particularly with the current rate of mosquito breeding site elimination falling short of the desired target.
Probolinggo’s Multi-Pronged Approach to Dengue Control
The “Gerak Bersama Pencegahan Dan Pengendalian DBD Dengan PSN 3M Plus Lavenderisasi” – a mouthful translating to “Joint Movement for Dengue Fever Prevention and Control with 3M Plus Lavenderization” – is the centerpiece of Probolinggo’s current strategy. The “3M” refers to a long-standing public health campaign: *Menutup* (covering), *Menguras* (emptying/cleaning), and *Menyemprot* (spraying) – covering water storage containers, draining standing water, and spraying insecticide. Adding lavender to the mix represents a shift towards more environmentally friendly and potentially sustainable methods. According to Dr. Intan Sudarmadi, Head of the Health Office, Population Control and Family Planning of Probolinggo City, the initiative aims to not only repel mosquitoes but also to create new economic opportunities for residents. Radar Bromo reported on the initiative earlier this month.
The choice of lavender is based on its known repellent properties. The plant contains compounds that mosquitoes find unpleasant, offering a natural alternative to chemical insecticides. While the effectiveness of lavender as a standalone mosquito repellent is still a subject of ongoing research, studies suggest that its scent can disrupt the mosquitoes’ ability to locate hosts. Times Indonesia highlights the potential for lavender cultivation to also boost local tourism, transforming the city into a fragrant and visually appealing destination.
Addressing the Root Causes: Breeding Sites and Community Involvement
Despite the innovative lavender initiative, officials acknowledge that the core of dengue control remains focused on eliminating mosquito breeding sites. The current rate of “zero jentik” (larvae-free) homes stands at 78.8%, falling short of the minimum target of 90%. This indicates a significant potential for continued transmission. Kanigaran district remains the most affected area, accounting for 103 cases and two deaths in 2025. The continued high incidence in this area underscores the need for targeted interventions and sustained community engagement. The city government is actively encouraging residents to regularly inspect their properties for standing water in containers like flower pots, tires, and buckets, and to take steps to eliminate these breeding grounds.
The success of the program hinges on widespread community participation. The initiative isn’t simply a top-down directive. it’s designed to empower residents to take ownership of their health and contribute to a collective effort. By providing lavender seedlings and educating the public about mosquito control measures, the city hopes to foster a sense of shared responsibility. The potential economic benefits of lavender cultivation – from selling the plants themselves to creating lavender-based products – are also intended to incentivize participation.
Lavender Beyond Repellency: Economic and Aesthetic Benefits
The Probolinggo government envisions lavender as more than just a mosquito repellent. The plant’s aesthetic appeal and versatility offer opportunities for economic diversification. Local authorities are exploring the possibility of developing lavender-themed tourism attractions, such as lavender farms and gardens, which could draw visitors and generate revenue. Lavender can be used to produce a range of products, including essential oils, soaps, and perfumes, creating new income streams for local entrepreneurs. Reports suggest that the city is actively seeking partnerships with local businesses to develop and market these products.
This integrated approach – combining public health interventions with economic development initiatives – is a hallmark of Probolinggo’s strategy. By addressing both the immediate threat of dengue fever and the long-term economic well-being of its citizens, the city aims to create a more resilient and sustainable community. The initiative also aligns with broader global trends towards promoting nature-based solutions to public health challenges.
The Broader Context: Dengue Fever in Indonesia and Globally
Indonesia is endemic for dengue fever, with outbreaks occurring regularly, particularly during the rainy season. The country experiences a significant burden of the disease, with hundreds of thousands of cases reported annually. The Ministry of Health has implemented various programs to control dengue fever, including vector control, surveillance, and public education campaigns. However, the effectiveness of these programs is often hampered by limited resources, inadequate infrastructure, and challenges in community engagement.
Globally, the incidence of dengue fever has been increasing in recent decades, driven by factors such as climate change, urbanization, and increased international travel. The World Health Organization (WHO) estimates that approximately half of the world’s population is now at risk of dengue fever. The development of a safe and effective dengue vaccine remains a priority, but progress has been slow. Current efforts focus on preventing mosquito bites, early diagnosis and treatment, and effective vector control strategies. The Probolinggo initiative, with its emphasis on community participation and natural repellents, offers a potentially valuable model for other dengue-prone regions.
As of March 2026, Probolinggo has already recorded 39 cases of dengue fever, raising concerns about a potential surge in infections. The city government is urging residents to remain vigilant and to actively participate in the ongoing prevention efforts. The success of the lavender initiative, combined with sustained adherence to the 3M principles, will be crucial in mitigating the risk of a large-scale outbreak.
