【城市野化（Urban Rewilding）與自然式植栽（Naturalistic Planting）】

城市野化強調最小化人為干預，讓植被自然演替；自然式植栽則模仿自然生態，以多樣原生或適應性植物形成複合群落。國內外研究顯示，這兩者能革新都市綠地結構、構築生態網絡，並帶來顯著的環境與氣候效益。以下依據國際科學文獻（如牛津大學、LSE Grantham Institute等研究）與台灣相關應用案例（如宮脇式造林法導入），逐點說明。

👉1. 結構革新：多層次複層群落 / 食物森林
傳統都市植栽多為單一層次（如草坪或單種樹木），易受氣候衝擊且維護成本高。城市野化與自然式植栽則採用多層次複層群落（multi-layered polyculture），模擬自然森林結構：包含冠層樹木、亞冠層灌木、地被層、藤蔓與根層，形成食物森林（Food Forest）。
🍀研究支持：國際文獻指出，食物森林作為自然基礎解決方案（Nature-based Solutions），能快速建立自我維持的生態系統，2–3年內即達近免維護狀態，比傳統造林更具韌性。美國林務局與多篇都市農業研究顯示，此結構可垂直利用空間，提升產量與生態功能。
🍀台灣應用：台灣引入日本宮脇式造林法（Miyawaki Method），密集種植多種原生植物，形成複層森林，已在都市隙地與校園應用。研究顯示，此法比傳統單層植栽更快達到穩定群落，生物多樣性與土壤健康顯著提升。
🍀益處：結構複雜度提高後，系統更能抵抗極端氣候，降低維護成本，並提供食物、遮蔭等多重服務。

👉2. 生態網絡
城市野化透過留白與自然演替，串聯碎片化的綠地，形成生態網絡（Ecological Networks），包括綠廊道、棲地走廊與生物多樣性節點。
🍀國際證據：柏林等城市研究顯示，野化區能促進物種遷移、基因交流與生態連通性，避免孤島效應。英國Rewilding Britain與歐洲都市生態研究指出，連接的綠地網絡可提升整體生態韌性。
🍀台灣脈絡：雖規模較小，但台北田園城市政策與橋下自然式植栽實驗（中興大學、嘉義大學等團隊），已開始透過隙地與河岸植栽構築小型生態網絡，強化都市與周邊自然連結。此網絡不僅保護野生動物，還讓都市居民更容易接觸自然，提升心理健康。

👉3. 關鍵效益：碳匯能力提升、調節微氣候、生物多樣性提升
多篇國際研究（如2024–2025年牛津大學、LSE與Nature系列論文）證實，城市野化與自然式植栽的複層結構遠優於傳統綠化：
🍀碳匯能力提升：複雜植被（含根系與土壤）能固定更多碳，比單一樹木種植或人工林更高效。Rewilding研究顯示，野化景觀的碳儲存量更高，且具長期穩定性；部分案例中，土壤與生物質碳匯優於傳統造林。 台灣宮脇式應用亦顯示，密集複層森林的固碳能力顯著高於傳統方式。
🍀調節微氣候：多層植被能降低都市熱島效應、增加保濕、過濾空氣污染物，並改善 stormwater 管理。研究指出，野化綠地可創造涼爽微氣候，減少能源消耗。
🍀生物多樣性提升：最小干預促進自然演替，提供多樣棲位，吸引授粉昆蟲、鳥類與微生物。都市野化區的物種豐富度常高於人工綠地，包含瀕危物種。

👉4. 指標案例：德國柏林自然公園（Natur-Park Südgelände）
柏林Natur-Park Südgelände（前身為廢棄鐵路調車場）是全球公認的城市野化典範，1980年代起因停用而自然演替，1999年正式開放為自然公園，面積約18公頃。
🍀轉型過程：早期生態調查發現自然演替已形成豐富棲地，規劃採「分區管理」——部分區域完全野化（無干預），部分適度控制以保護稀有物種，保留鐵路遺跡作為文化元素。
🍀生態成果（最新調查）：
◎植物：超過350種（含多種瀕危物種，如meadow hawkweed）。
◎動物：30種繁殖鳥類、95種野生蜜蜂（佔柏林蜜蜂物種約1/3）、57種蜘蛛、15種蚱蜢，以及49種大型真菌。
◎外來物種亦融入，形成新型都市生態。
🍀都市貢獻：提供高品質綠地、生物多樣性熱點，同時作為教育與休憩空間，證明野化不僅可行，還能與都市生活和諧共存。柏林其他野化案例（如柏林牆綠帶）更擴大成生態網絡，強化全城韌性。

👉城市野化與自然式植栽是低成本、高效益的都市永續策略，能回應氣候變遷、生物多樣性危機與居民福祉。可借鏡柏林模式，從屋頂、橋下、閒置地開始，結合宮脇式與食物森林概念，逐步建構更具生命力的都市生態。未來若能納入更多量化監測（如碳匯數據），將進一步強化政策推動。這些做法不僅是綠化，更是讓都市「重新野化」回歸自然平衡。

Urban Rewilding and Naturalistic Planting
Urban rewilding emphasizes minimizing human intervention to allow vegetation to undergo natural succession. Naturalistic planting, on the other hand, imitates natural ecosystems by creating complex communities using diverse native or climate-adapted plants. Domestic and international research shows that both approaches can revolutionize urban green space structures, build ecological networks, and deliver significant environmental and climate benefits. The following explanation is based on international scientific literature (such as studies from Oxford University and the LSE Grantham Institute) and Taiwan-specific application cases (such as the introduction of the Miyawaki Method).
👉1. Structural Innovation: Multi-layered Complex Communities / Food Forests
Traditional urban planting is mostly single-layered (e.g., lawns or monoculture trees), making it vulnerable to climate shocks and costly to maintain. Urban rewilding and naturalistic planting instead adopt multi-layered polycultures that simulate natural forest structures—including canopy trees, subcanopy shrubs, ground-cover layers, vines, and root layers—to create food forests.
🍀 Research Support: International literature highlights food forests as nature-based solutions that can rapidly establish self-sustaining ecosystems, reaching near maintenance-free status within 2–3 years and offering greater resilience than conventional afforestation. Studies by the U.S. Forest Service and multiple urban agriculture reports show that this structure makes vertical use of space, boosting both productivity and ecological functions.
🍀 Taiwan Application: Taiwan has adopted Japan’s Miyawaki Method, densely planting multiple native species to form multi-layered forests. It has already been applied in urban gaps and school campuses. Research demonstrates that this approach reaches stable communities faster than traditional single-layer planting, with marked improvements in biodiversity and soil health.
🍀 Benefits: Once structural complexity increases, the system becomes far more resistant to extreme weather, significantly reduces maintenance costs, and delivers multiple services such as food production and shade.
👉2. Ecological Networks
Urban rewilding creates ecological networks by leaving areas undisturbed for natural succession, linking fragmented green spaces through green corridors, habitat pathways, and biodiversity nodes.
🍀 International Evidence: Studies in cities such as Berlin show that rewilded zones promote species migration, gene flow, and ecological connectivity, preventing island effects. Organizations like Rewilding Britain and European urban ecology research indicate that connected green networks enhance overall ecosystem resilience.
🍀 Taiwan Context: Although smaller in scale, Taipei’s Garden City policy and under-bridge naturalistic planting experiments (led by teams from National Chung Hsing University and National Chiayi University) have begun building small-scale ecological networks via vacant lots and riverbanks. These networks not only protect wildlife but also make it easier for urban residents to connect with nature, improving mental well-being.
👉3. Key Benefits: Enhanced Carbon Sequestration, Microclimate Regulation, and Increased Biodiversity
Multiple international studies (including 2024–2025 papers from Oxford University, the LSE, and Nature journals) confirm that the multi-layered structure of urban rewilding and naturalistic planting far outperforms traditional greening:
🍀 Enhanced Carbon Sequestration: Complex vegetation (including root systems and soil) sequesters far more carbon than single-tree planting or monoculture forests. Rewilding research shows that rewilded landscapes store higher amounts of carbon with greater long-term stability; in some cases, soil and biomass carbon storage exceeds that of conventional plantations. Taiwan’s Miyawaki applications similarly demonstrate significantly higher carbon-fixing capacity in dense multi-layered forests.
🍀 Microclimate Regulation: Multi-layered vegetation reduces the urban heat island effect, increases humidity, filters air pollutants, and improves stormwater management. Studies show that rewilded green spaces create cooler microclimates and lower energy consumption.
🍀 Increased Biodiversity: Minimal intervention encourages natural succession, providing diverse niches that attract pollinators, birds, and microorganisms. Species richness in urban rewilded areas is often higher than in manicured green spaces and frequently includes endangered species.
👉4. Landmark Case: Natur-Park Südgelände in Berlin, Germany
Berlin’s Natur-Park Südgelände (formerly a disused railway marshalling yard) is a globally recognized model of urban rewilding. Natural succession began in the 1980s after the site was abandoned; it was officially opened as a nature park in 1999, covering approximately 18 hectares.
🍀 Transformation Process: Early ecological surveys revealed that natural succession had already created rich habitats. The park adopted a “zoned management” approach—some areas are left completely wild (no intervention), while others receive light management to protect rare species. Railway relics are preserved as cultural features.
🍀 Ecological Outcomes (latest surveys):
◎ Plants: Over 350 species (including several endangered ones, such as meadow hawkweed).
◎ Animals: 30 breeding bird species, 95 species of wild bees (about one-third of Berlin’s bee species), 57 spider species, 15 grasshopper species, and 49 species of macrofungi.
◎ Non-native species have also integrated, forming a novel urban ecosystem.
🍀 Urban Contributions: The park provides high-quality green space and a biodiversity hotspot while serving as an educational and recreational area. It proves that rewilding is not only feasible but can harmoniously coexist with city life. Other Berlin rewilding projects (such as the Berlin Wall Green Belt) have expanded into city-wide ecological networks, strengthening urban resilience.
Conclusion
Urban rewilding and naturalistic planting represent low-cost, high-impact strategies for sustainable urban development. They address climate change, the biodiversity crisis, and residents’ well-being. By learning from the Berlin model, cities can begin with rooftops, under-bridge spaces, and idle land, combining the Miyawaki Method with food forest concepts to gradually build more vibrant urban ecosystems. Incorporating more quantitative monitoring (such as carbon sequestration data) in the future will further strengthen policy implementation. These practices go beyond simple greening—they represent a true “rewilding” of cities, restoring balance with nature.

Urban Balcony Gardening: 8 Beginner-Proof, Foolproof Summer Herbs for Taiwan Balconies – Ready for Your Table
Taipei’s summer is heavily affected by the urban heat island effect, with temperatures often exceeding 35°C and afternoon thunderstorms occurring almost daily. This creates a tough challenge for traditional Mediterranean herbs. However, based on years of “summer-survival variety” screening research by Taiwan’s Ministry of Agriculture (MOA) and regional agricultural improvement stations, combined with empirical data from international tropical container gardening studies, you can turn your city balcony into a thriving mini farm — as long as you choose the right varieties and master the three key principles: shade, ventilation, and drainage!
Below is a re-ordered recommendation of 8 beginner-friendly summer herbs, ranked by growth resilience, Taiwan summer adaptability, and scientific evidence (starting with the most heat- and humidity-tolerant “unbeatable champions”):
👉1. Thai Basil (九層塔) —— Tropical Climate’s Guardian King
🍀Scientific Evidence: Research from the Kaohsiung District Agricultural Improvement Station highlights Thai Basil’s excellent heat tolerance and strong pest/disease resistance, making it the most stable summer-survival variety in Taiwan. International studies also show it synthesizes essential oils fastest above 30°C, delivering the most intense aroma.
🍀Culinary Uses: Three-cup chicken, Thai basil scrambled eggs, clam soup, salt-and-pepper fried chicken (deodorizing).
🍀Cultivation Tips: Loves full sun — west-facing balconies are fine too. Use the “pinching method” (remove the top bud) to encourage side branching and prevent early flowering and aging.
👉2. Perilla (紫蘇) —— Functional Oriental Super Herb
🍀Scientific Evidence: Taiwan summer balcony field studies classify it as a “functional immune plant” with astonishing growth speed. Subtropical container research confirms Perilla has extremely strong adaptability to the humid, muggy conditions of the Taipei Basin.
🍀Culinary Uses: Sushi wraps, raw fish salad, perilla plum juice, salt-and-pepper chicken (deodorizing).
🍀Cultivation Tips: Thrives in half-day to full sun. Leaves wilt visibly when thirsty — water immediately. Pinching and harvesting encourages denser growth.
👉3. Lemongrass (檸檬香茅) —— Structurally Tough Moisture-Loving Champion
🍀Scientific Evidence: Agricultural stations across Taiwan frequently list it as the top choice for summer greening and natural mosquito repellent. Its robust root system, confirmed by international container gardening studies, adapts exceptionally well to high-humidity potted environments without rotting from waterlogging.
🍀Culinary Uses: Thai tom yum soup, lemongrass tea, deodorizing meat dishes.
🍀Cultivation Tips: Use a pot at least 30 cm in diameter to give roots ample space. Keep soil evenly moist.
👉4. Mint (薄荷) —— High-Efficiency Transpiration Cooling Agent
🍀Scientific Evidence: Adaptation assessments in southern high-temperature regions show Mint has extremely high survival rates under partial shade. Its rapid growth helps regulate balcony microclimate through leaf transpiration.
🍀Culinary Uses: Mojito cocktails, iced tea, fruit salads, dessert garnishes.
🍀Cultivation Tips: Must be planted in its own pot to prevent underground runners from invading other plants. Water once in the morning and once in the evening during summer to keep soil lightly moist.
👉5. Sweet Basil (甜羅勒) —— Pesto Lovers’ Summer Blessing
🍀Scientific Evidence: Same family as Thai Basil but with softer leaves. MOA studies confirm that, if protected from direct heavy rain, both yield and aroma remain at high levels throughout Taiwan’s summer.
🍀Culinary Uses: Classic pesto, Margherita pizza, tomato and mozzarella salad.
🍀Cultivation Tips: Soil should be rich in trace elements (apply light organic fertilizer). Harvest by cutting the whole stem to encourage more new shoots from the base.
👉6. Oregano (奧勒岡) —— Dry-or-Wet All-Rounder & Pizza Hero
🍀Scientific Evidence: International tropical herb guides confirm its high tolerance to heat. Taiwan organic cultivation research shows that after drying, the key aroma compound (Carvacrol) becomes even more pronounced — perfect for summer harvest and storage.
🍀Culinary Uses: Homemade pizza, tomato meat sauce, Greek salad, bread spreads.
🍀Cultivation Tips: Loves full sun with excellent drainage. Cuttings root extremely easily for propagation.
👉7. Rosemary (迷迭香) —— Adapted Heat-Tolerant Mediterranean Star
🍀Scientific Evidence: Although originally Mediterranean, heat-adapted varieties bred by the Kaohsiung station now thrive in Taiwan summers. Studies recommend extra ventilation in summer to avoid “wet-heat” root suffocation.
🍀Culinary Uses: Pan-seared steak, roasted potatoes, sous-vide chicken breast, homemade herb oil.
🍀Cultivation Tips: Mix plenty of perlite or coarse sand into the medium for superior drainage. Water only after soil is completely dry; provide light shade during intense afternoon sun.
👉8. Thyme (百里香) —— Tiny but Mighty Stress-Resistant Hero
🍀Scientific Evidence: The MOA cultivation manual notes Thyme grows best at 20–30°C; with 50% shade it safely survives Taiwan summers. Its compact size makes it ideal for space-limited urban balconies.
🍀Culinary Uses: Italian pasta, braised meats, Mediterranean-style grilled fish.
🍀Cultivation Tips: Avoid direct rain. Water at the base and keep leaves dry to prevent fungal issues in hot, humid conditions.

👉 Core Summer Cultivation Tips
🍀Based on the MOA Summer Gardening Guide and international container gardening research, mastering these four points will dramatically boost your success rate:
🍀Physical Shade Protection: Install 50-60% shade netting on your balcony to lower leaf temperature and prevent afternoon thunderstorms from washing away the soil.
🍀Medium Optimization: Use “herb-specific potting mix” rich in wood fiber and perlite. Maintain pH 6.5-7.0 to ensure excellent root respiration.
🍀Precise Watering: Avoid watering during midday heat; follow a “morning and evening” schedule. Never let water accumulate in the saucer beneath the pot — this prevents mosquitoes and root rot.
🍀Ventilation and Harvesting: Harvesting is pruning! Regularly pinch off the top leaves to improve air circulation and reduce the chance of powdery mildew.

👉 Beginner Starter Pack: Start with three pots — Thai Basil + Lemongrass + Mint. These three have nearly “unbeatable genes” for Taiwan summers. They’ll quickly build your planting confidence and deliver fresh herbs to your table every day.

#一起做好居家防治 #驅鼠是每位臺北市民的責任 #公民素養

【老鼠驅趕方法與香草精油輔助：生態友善指引】

根據2026年上半年的最新報導與台北市政府的防治評估，近期爆發的「安鼠之亂」主要源於都市結構老化、環境食物來源充沛，以及大規模都市更新引發的老鼠棲地遷移。柯紹華醫師與前台北市政府社會局局長許立民指出，師大路至泰順街、古亭國小一帶密集都更拆除老舊建物時，若缺乏事前精準滅鼠配套，老鼠即被迫「難民化」竄逃至鄰近住宅與街道，形成當前亂象。

老鼠驅趕的核心仍是「整合式害蟲管理」（IPM），優先環境管理（封堵入口、斷絕食物、清除藏身處），再輔以物理與天然方法。強烈建議避免使用老鼠藥（尤其是第二代抗凝血劑SGARs），因為會透過食物鏈造成二次中毒，嚴重危害老鼠的天敵，如老鷹、貓頭鷹、鳳頭蒼鷹、黑鳶等猛禽，以及石虎、野貓等其他野生動物。這些毒素在猛禽體內累積，導致內出血、行動遲緩甚至死亡，破壞生態平衡，反而可能讓老鼠族群因天敵減少而反彈。政府已於2015年停辦全國滅鼠週，就是為了保護黑鳶等保育類猛禽。鼠藥雖能短期殺鼠，但老鼠繁殖快、易產生抗藥性，長期效果有限，且對寵物、兒童也有風險。目前環境部已公開呼籲地方以環境整頓為主、藥劑為輔，避免大規模投藥。

👉1. 國內外研究支持的驅趕方法
台灣環保署、環境部一貫強調「防鼠三不原則」：不讓鼠來（封堵≤1cm縫隙、使用金屬紗網）、不讓鼠吃（食物／廚餘密封、垃圾每日清）、不讓鼠住（整理環境、清除雜物）。國際上同樣推崇IPM，強調物理＋天然方法，避免抗凝血劑因二次中毒危害禿鷹、紅尾鷹等猛禽（全球猛禽檢體中60%以上驗出鼠藥殘留）。研究一致顯示：鼠藥無法長期控制鼠患，反而破壞食物鏈。

🍀物理方法（最推薦）：捕鼠籠（人道、可重複使用，避免死鼠在家中腐爛傳病）；黏鼠板（效率低、較不人道，僅作輔助）。
🍀天然氣味法：薄荷油、尤加利油、香茅油等。台大昆蟲系名譽教授徐爾烈指出，老鼠嗅覺敏銳，強烈刺激氣味可暫時驅避，但需定期補充。
🍀超音波驅鼠器：效果因環境而異，老鼠可能適應。
🍀養貓：天然天敵，但需考量居住環境。
🍀避免化學方法：第二代抗凝血劑毒餌雖曾被建議置於誘餌盒，但會危害猛禽等天敵。

👉2. 哪些香草精油有實證可驅趕老鼠？(適合居家環境)
🍀精油類是目前最環保、安全的輔助方式，對猛禽等天敵無害。實驗（行為測試、食物消耗量、徑向迷宮、明暗轉移測試）證實，強烈刺激性精油可讓老鼠產生厭惡感，減少進入與取食。尤加利精油證據最充分，適合台灣家庭使用。效果短期（揮發快），需每1-7天補充，高濃度或製成蠟塊較持久；組合使用效果更好。老鼠可能適應，故搭配環境管理最佳。

🍀尤加利精油 (Eucalyptus oil)
◎核心成分：富含1,8-桉葉油醇 (1,8-Cineole)。
◎研究實證：印度旁遮普農業大學（PAU）針對家鼠（Rattus rattus）進行測試，發現噴灑高濃度尤加利精油或放置精油蠟塊，能顯著降低老鼠的食物消耗量與停留時間。
◎特性：這是目前國際研究中證據力最強的種類，其強烈氣味能有效干擾老鼠的通訊與覓食路徑。

🍀胡椒薄荷精油 (Peppermint oil, Mentha piperita)
◎核心成分：薄荷醇 (Menthol)。
◎研究實證：廣泛應用於國際開放場域（Open Field）與迷宮測試。薄荷醇對齧齒動物的鼻腔黏膜具有強烈刺激性，能引發避忌行為。台灣徐爾烈教授觀察亦顯示，噴灑後老鼠會暫時逃離洞穴。
◎特性：揮發速度極快，在密閉空間效果較佳。開放空間需透過棉球浸潤或頻繁補充（約3-7天）以維持濃度。

🍀香茅與檸檬草精油 (Citronella & Lemongrass)
◎核心成分：香茅醛 (Citronellal) 與檸檬醛 (Citral)。
◎研究實證：泰國徑向迷宮測試顯示，這兩類精油能產生強烈的嗅覺屏障，短期與長期驅避表現均穩定。
◎特性：台灣民間與農業推廣中常提及用於儲糧害獸防治，建議與其他精油組合使用以產生協同效應。（註：目前尚未見大型官方量化農業推廣報告針對屋頂鼠的特定數據，但國際實證支持其輔助效果。）

🍀橙油 (Orange oil) 與薑油 (Ginger oil)
◎研究實證：泰國對比研究顯示，橙油與薑油在噴灑一週後的殘留驅避效果，甚至優於單純薄荷精油。
◎特性：含有複雜揮發性有機化合物，老鼠適應速度較慢，適合需要較長時效的環境。
茶樹精油 (Tea tree) 與玫瑰草精油 (Palmarosa / Cymbopogon martinii)
◎研究實證：塞爾維亞毒理學研究發現，高濃度（約0.0625%以上）混入誘餌，能顯著降低老鼠對該區域食物的偏好指數。
◎特性：適合阻斷老鼠對特定取食點的依賴。

🍀關鍵結論：尤加利精油國際實證最強，台灣環保與友善動物團體也大力推薦。精油無二次中毒風險，對猛禽等天敵完全安全，是取代鼠藥的最佳選擇。局限：非殺鼠劑，只能驅避；重度鼠患仍需環境＋物理方法。
🍀注意事項：以上精油用於驅鼠時（棉球、噴霧、蠟塊），寵物可能透過吸入蒸氣、皮膚接觸、舔舐或踩踏而暴露風險。貓特別敏感（缺乏分解酚類化合物的肝酶），即使低濃度也可能中毒；狗相對耐受性較高，但仍不建議直接使用。若您家有狗貓，請優先選擇非化學、非精油的生態友善方式，例如：乾燥薄荷葉或丁香香包。

👉3. 實用建議（結合國內外最佳做法＋生態優先）
🍀先環境管理（最根本，80%問題可解決）：落實「三不原則」，封洞、斷糧、清潔。針對「安鼠之亂」都更區，建議住戶先檢查管道間與牆縫。
🍀優先天然／物理：用尤加利或薄荷＋香茅精油（棉球／噴霧／蠟塊），置於牆角、入口、櫥櫃；每1-3天補充。搭配捕鼠籠監測。
🍀完全避免老鼠藥：除生態危害外，還可能培養抗藥性「超級老鼠」。若鼠患極嚴重，聯絡專業業者（要求非化學方案）或環保局。
🍀安全提醒：精油稀釋使用，遠離寵物（尤其是貓可能敏感）；孕婦、幼童家慎用高濃度。
🍀監測與求助：放捕鼠籠確認效果；持續問題可向環保局通報或找專業除鼠（強調生態友善）。
🍀處理老鼠排泄物或屍體時，務必先佩戴口罩、手套，開窗通風，以稀釋漂白水（100cc市售漂白水＋1公升清水）潑灑污染處，待30分鐘後再清理，以防範漢他病毒或鼠疫等嚴重疾病。

👉總之，環境管理＋精油驅避＋物理捕捉 是最有效、也最友善生態的組合，能保護老鷹等天敵，維持自然平衡。維持生態平衡，保持環境乾淨，就是對野生動物與自身健康最好的幫助。

Mouse Control Methods and Herbal Essential Oil Assistance: An Eco-Friendly Guide
According to the latest reports from the first half of 2026 and Taipei City Government’s pest control assessment, the recent “An Rat Chaos” outbreak stems mainly from aging urban infrastructure, abundant environmental food sources, and large-scale urban renewal projects that have triggered the displacement of rat habitats. Dr. Ko Shao-hua and former Taipei City Government Social Affairs Bureau Director Hsu Li-min pointed out that during intensive urban renewal demolitions around Shida Road to Taishun Street and Guting Elementary School, the lack of prior precise rodent control measures forced rats to become “refugees,” fleeing into nearby residential areas and streets, creating the current crisis.
The core of mouse control remains Integrated Pest Management (IPM): prioritize environmental management (sealing entry points, eliminating food sources, and removing hiding spots), then supplement with physical and natural methods. We strongly recommend avoiding rodenticides (especially second-generation anticoagulant rodenticides, SGARs), as they cause secondary poisoning through the food chain and seriously threaten the natural predators of rats—such as eagles, owls, crested goshawks, black kites, and other raptors—as well as leopard cats, feral cats, and other wild animals. These toxins accumulate in raptors, causing internal bleeding, sluggish movement, and even death, disrupting the ecological balance and potentially allowing rat populations to rebound due to reduced natural predators. The government suspended the National Rodent Control Week in 2015 precisely to protect black kites and other protected raptors. Although rodenticides can kill rats quickly, rats reproduce rapidly and easily develop resistance, making long-term control ineffective; they also pose risks to pets and children. The Ministry of Environment has publicly urged local governments to focus on environmental cleanup as the primary approach, using chemical agents only as a last resort and avoiding large-scale baiting.
👉 1. Domestic and International Research-Supported Control Methods
Taiwan’s Environmental Protection Administration and Ministry of Environment have long emphasized the “Three No’s Principle for Rat Prevention”:

No entry for rats (seal gaps ≤1 cm, use metal mesh screens)
No food for rats (seal food and kitchen waste, dispose of garbage daily)
No shelter for rats (tidy up the environment and remove clutter).

Internationally, IPM is equally promoted, emphasizing physical + natural methods and avoiding anticoagulant rodenticides due to secondary poisoning risks to bald eagles, red-tailed hawks, and other raptors (over 60% of global raptor specimens show rodenticide residues). Research consistently shows that rodenticides cannot provide long-term rat control and instead damage the food chain.
🍀 Physical Methods (Most Recommended): Live traps (humane and reusable, preventing dead rats from rotting indoors and spreading disease); glue boards (low efficiency and less humane, for auxiliary use only).
🍀 Natural Scent Methods: Peppermint oil, eucalyptus oil, citronella oil, etc. National Taiwan University Entomology Professor Emeritus Hsu Er-lieh notes that rats have an acute sense of smell; strong irritating scents can temporarily repel them, but must be replenished regularly.
🍀 Ultrasonic Repellers: Effectiveness varies by environment; rats may become accustomed to the sound.
🍀 Keeping Cats: Natural predators, but suitability depends on living conditions.
🍀 Avoid Chemical Methods: Although second-generation anticoagulant bait stations were once suggested, they harm raptors and other predators and are strongly advised against.
👉 2. Which Herbal Essential Oils Have Scientific Evidence for Repelling Rats?
🍀 Essential oils are currently the most environmentally friendly and safe supplementary method, posing no risk of secondary poisoning to raptors or other wildlife. Experiments (behavioral tests, food consumption measurements, radial maze tests, and light-dark transition tests) confirm that strong irritant essential oils can create aversion in rats, reducing entry and feeding. Eucalyptus oil has the strongest evidence and is highly suitable for Taiwanese households. Effects are short-term (due to rapid volatility), requiring replenishment every 1–7 days; higher concentrations or wax blocks last longer, and combinations work best. Rats may habituate, so pairing with environmental management is essential.
🍀 Eucalyptus Oil (Eucalyptus oil)
◎ Core Component: Rich in 1,8-cineole.
◎ Research Evidence: Punjab Agricultural University (PAU) in India tested it on roof rats (Rattus rattus) and found that spraying high-concentration eucalyptus oil or using eucalyptus wax blocks significantly reduced food consumption and time spent in treated areas.
◎ Characteristics: Currently the strongest evidence-based option in international research; its potent scent effectively disrupts rats’ communication and foraging pathways.
🍀 Peppermint Oil (Peppermint oil, Mentha piperita)
◎ Core Component: Menthol.
◎ Research Evidence: Widely used in international open-field and maze tests. Menthol strongly irritates the nasal mucosa of rodents, triggering avoidance behavior. Professor Hsu Er-lieh’s observations also show that spraying causes rats to temporarily flee burrows.
◎ Characteristics: Extremely volatile; works best in enclosed spaces. In open areas, use cotton balls or replenish frequently (every 3–7 days) to maintain concentration.
🍀 Citronella & Lemongrass Oil (Citronella & Lemongrass)
◎ Core Components: Citronellal and citral.
◎ Research Evidence: Thai radial maze tests show these oils create a strong olfactory barrier with stable short- and long-term repellent effects.
◎ Characteristics: Frequently mentioned in Taiwan’s民间 and agricultural extension programs for stored-grain pest control. Best used in combination with other oils for synergistic effects. (Note: No large-scale official quantitative agricultural reports specifically target roof rats, but international evidence supports their auxiliary role.)
🍀 Orange Oil (Orange oil) & Ginger Oil (Ginger oil)
◎ Research Evidence: Thai comparative studies show that orange and ginger oils retain repellent effects one week after spraying, sometimes outperforming peppermint oil alone.
◎ Characteristics: Contain complex volatile organic compounds; rats adapt more slowly, making them suitable for environments needing longer-lasting effects.
🍀 Tea Tree Oil (Tea tree) & Palmarosa Oil (Palmarosa / Cymbopogon martinii)
◎ Research Evidence: Serbian toxicology studies found that high concentrations (above approximately 0.0625%) mixed into bait significantly reduced rats’ preference index for treated food sources.
◎ Characteristics: Ideal for blocking rats’ reliance on specific feeding sites.
🍀 Key Conclusion: Eucalyptus oil has the strongest international scientific backing, and Taiwan’s environmental protection and animal-friendly groups also strongly recommend it. Essential oils carry no secondary poisoning risk and are completely safe for raptors and other predators, making them the best rodenticide alternative. Limitations: They are not rodenticides—they only repel. Severe infestations still require environmental management + physical methods.
🍀Important Note: When using the above essential oils for rodent control (cotton balls, sprays, or wax blocks), pets may be exposed through inhalation of vapors, skin contact, licking, or stepping on treated areas. Cats are especially sensitive (they lack the liver enzymes needed to break down phenolic compounds), and even low concentrations can cause poisoning. Dogs have relatively higher tolerance but direct use is still not recommended. If you have dogs or cats at home, please prioritize non-chemical, non-essential-oil eco-friendly methods, such as dried peppermint leaves or clove sachets.

👉 3. Practical Suggestions (Combining Best Domestic & International Practices + Ecological Priority)
🍀 Environmental Management First (The Most Fundamental Step—Solves 80% of Problems): Follow the “Three No’s Principle”—seal holes, cut off food, and clean thoroughly. In urban renewal areas affected by the “An Rat Chaos,” residents should first inspect pipe shafts and wall gaps.
🍀 Prioritize Natural/Physical Methods: Use eucalyptus or peppermint + citronella essential oils (cotton balls / spray / wax blocks) at corners, entrances, and cabinets; replenish every 1–3 days. Monitor with live traps.
🍀 Completely Avoid Rodenticides: Besides ecological harm, they may create “super rats” with resistance. If the infestation is severe, contact professional pest control services (request non-chemical solutions) or the Environmental Protection Bureau.
🍀 Safety Reminders: Dilute essential oils before use; keep away from pets (cats are especially sensitive); use high concentrations cautiously in households with pregnant women or young children.
🍀 Monitoring & Assistance: Use live traps to confirm effectiveness. For ongoing issues, report to the Environmental Protection Bureau or seek eco-friendly professional rodent control.
🍀 Handling Rat Droppings or Carcasses: Always wear a mask and gloves, open windows for ventilation, and disinfect affected areas with diluted bleach (100 cc household bleach + 1 liter water). Wait 30 minutes before cleaning to prevent hantavirus or plague.

👉 In Summary, environmental management + essential oil repellents + physical trapping is the most effective and eco-friendly combination. It protects eagles and other natural predators while maintaining ecological balance. Keeping the environment clean is the best way to safeguard wildlife and our own health.
