Chemical-based mosquito repellents, such as those containing DEET, permethrin, or pyrethroids, can have significant negative effects on non-target organisms, including beneficial insects like bees and butterflies, as well as aquatic life if runoff occurs. These chemicals can also contribute to the development of pesticide resistance in mosquito populations, making future control efforts more challenging. On the other hand, natural or organic repellents, often based on essential oils like citronella or eucalyptus, generally pose less risk to the environment but may require more frequent application to maintain effectiveness. Additionally, the overuse of any mosquito repellent can lead to soil and water contamination, affecting plant health and local biodiversity. Integrated pest management strategies, which combine repellents with habitat modification and biological controls, offer a more sustainable approach to mosquito control while minimizing environmental impact.
