Why Your Mosquito Plants Aren’t Working

It is entirely understandable why homeowners across Singapore look for simple, natural ways to keep their families safe from mosquitoes. The idea of placing a beautifully fragrant pot of mosquito-repelling plants such as Basil, Citronella Grass, Catnip, or Lavender on your balcony or patio and having a worry-free home is incredibly appealing.

Unfortunately, here at A-Flick, our role is to provide effective, science-backed solutions, and that means being honest: when it comes to effective mosquito control, the common belief that potted mosquito plants work is, simply put, a myth.

While these plants may smell wonderful, they offer virtually no real protection against the dangerous, disease-carrying mosquitoes prevalent in Singapore.

Here is a professional, friendly breakdown of why this popular home remedy falls short and what actually delivers real, reliable results.

The Fundamental Flaw: Plant vs. Product

The key scientific misunderstanding lies in confusing the plant material with the extracted essential oil.

1. The Repellent Compound Is Too Dilute

Many plants—such as lemongrass and citronella—naturally produce chemical compounds (like citronellal or geraniol) that mosquitoes dislike. This is why you see these ingredients in commercial repellent sprays, torches, and candles.

The critical difference is concentration and release rate:

• Commercial Products use highly concentrated, extracted essential oils to create a strong vapor barrier, and even these need constant reapplication because the oil quickly evaporates (a process called rapid volatilization).
• A Living Plant only releases a tiny, localized amount of its essential oil compounds into the surrounding air. The amount released is far too low to create a protective “bubble” around you, your patio, or your home.

A mosquito, driven by its need for a blood meal, will easily fly past the subtle scent of a potted plant to find you.

2. Scientific Testing Does Not Support the Claim

While we love hearing anecdotal success stories, when scientists conduct controlled experiments on popular mosquito-repellent plants, the results are consistently disappointing.

Study that evaluated the effectiveness of these plants when simply placed in an area have found no significant difference in mosquito landing rates on human subjects compared to areas with no plants at all. In fact, more mosquitoes landed on the mosquito plant leave than on a similar size and shape white paper leaf models!

In short, the plant’s presence does not deter the insects. If you rub the leaves and crush the oil onto your skin, you might get a few minutes of protection—but that is neither practical nor effective for long-term safety against pests.

3. These Plants Do Nothing to Stop Breeding

In Singapore, we are primarily fighting the Aedes mosquito, the vector for Dengue, Chikungunya, and Zika. The most effective way to eliminate these pests is not by trying to repel adults, but by eliminating their breeding grounds.

• Aedes mosquitoes are known as “container breeders” because they lay their eggs in small amounts of clean, stagnant water—often found in the very things homeowners use: flowerpot plates, vases, and outdoor containers.
• The plants themselves do not stop the female mosquito from laying eggs in the water nearby. Worse, if the plants are over-watered or placed in decorative pots with standing water, they can actually contribute to the problem by creating hidden breeding sites.

Effective control is about source reduction, not scent masking. If you are looking at buying effective repellents, check out our guide here.

The Takeaway for Homeowners: Choose Science Over Scent

While we wholeheartedly encourage you to grow any plant that brings you joy or fragrance, please do not rely on them as your primary line of defense against dangerous mosquito-borne illnesses. Relying on a myth puts your family at risk.

You need a strategy that targets the source and breaks the entire mosquito life cycle.
