No single plant kills adult mosquitoes, but several plants repel them or kill their larvae. The effectiveness varies, and often requires crushing the leaves to release the repellent oils. Large-scale mosquito control needs other methods.
Plants that Repel Mosquitoes:
Several plants are known for their mosquito-repelling properties due to the oils they produce. These plants don't kill mosquitoes directly but deter them from landing nearby.
- Citronella: This plant, often used in candles, repels mosquitoes with its scent. It's effective only when the plant's oils are released, which might involve crushing leaves or using commercially produced citronella oil.

Also noted in several articles from Garden Design, Home Depot, Odomos, and Reddit gardening discussions.]
- Lavender: The fragrant oil in lavender is also a mosquito repellent. [Source: 12 Mosquito Repellent Plants | Garden Design; Plants for mosquito control : r/gardening; 10 Plants That Repel Mosquitoes and Keep Them Away | Odomos]

Plants and Mosquito Larvae:
Some plants and plant-based strategies can help with mosquito larvae control:
- Certain plants may affect mosquito breeding sites indirectly. For example, by keeping standing water at bay. [Source: Battling Backyard Mosquitoes, Easily and Naturally — Wild Roots]
- Note that killing mosquito larvae requires different approaches than repelling adult mosquitoes. Methods such as using vegetable oil or dish soap on standing water are effective. [Source: How to kill mosquito larvae without harming plants - Quora]
Important Considerations:
Planting these plants might reduce mosquito presence in a small area, but they are not a substitute for comprehensive mosquito control methods, especially for large areas or significant infestations. For effective mosquito control in a larger area, you'll need other methods such as insecticides or professional services. [Source: Adulticides | Mosquitoes | CDC]
