Mosquito plague 2022: Which flowers and herbs really help against mosquitoes – and which do not?

Mosquitoes are probably the most unpopular insects in the world – and rightly so! Their tenacity can quickly ruin a barbecue or picnic in the great outdoors. Mosquito sprays aren’t always practical, and non-natural remedies are extremely harmful to both the environment and you. Fortunately, there are a handful of anti-mosquito plants that can drive away the pests and save your summer garden vacation.

What plants help against mosquitoes

There are several plants with mosquito repellent properties, some of which even deter other garden pests. However, there are also some that do not work at all. Many plants are often advertised as having mosquito repellent properties, but in most cases there is little to no scientific evidence to support these claims. That’s why we’ve created this list, where you’ll find not only the best plants that repel mosquitoes, but also those that only have a good reputation, but don’t protect against the pests at all.

What plants help against mosquitoes?

While many of these mosquito repellent plants contain certain amounts of citronella and other pest repellent oils, simply planting them will not necessarily solve your mosquito problems. In most cases, you’ll need to grate, crush or cut these plants to get them to release their valuable oils.

The 7 best plants that repel mosquitoes in the garden

Lemongrass for mosquitoes

We’ll start our list with the obvious. Citronella, or West Indian lemongrass, has a scientifically proven effect against biting mosquitoes. The essential oil it contains repels mosquitoes , which is why it is included in various insect repellent products such as candles, sprays and bracelets.

The citronella plant gives off a delicious lemony scent, which is why it is often confused with lemongrass. The two also look very similar, but are in fact very different plants.

This plant against mosquitoes does not release its essential oil by itself – it needs a little help. You need to chop or cut a few blades of grass, and the citronella oil will be released. For example, you can rub the cut blades of grass directly on your clothes or skin to keep the stinging insects away.

Get rid of those pesky mosquitoes with lavender

Lavender, with its delicious scent, is one of the most popular plants for gardens and patios. While this scent tantalizes our noses, mosquitoes just can’t stand it. Studies show that it has a similar effect on mosquitoes as DEET (diethyltoluamide), which is used to make anti-mosquito sprays.

Lavender has a dual action against the pests. In addition to the strong scent, the plant also contains linalool – a type of alcohol that repels mosquitoes.

In order to get the full effect of the repellent effect of lavender, it must be crushed or cut. How exactly you can use this fragrant plant against mosquitoes, find out in this article .

Catnip is a good anti-mosquito plant.

This lavender-like plant is known for sending our feline friends into a euphoric frenzy. But catnip is more than just an herb for cats. Its cute little flowers with purple spots will add color to your garden in no time .

In addition, catnip repels various insects, including mosquitoes. The chemical compound nepetalactone, which attracts cats, deters mosquitoes and other pesky summer pests.

Catnip is one of the few plants that deter mosquitoes on its own. However, there are ways to get the most out of this handy little herb. You can cut a few stems and spread them around your picnic area or patio, or make a simple catnip spray of your own.

Marigolds for biting insects.

Whether for planting in beds or attracting beneficial insects, marigolds are always considered a good choice for the garden. Even more so, as marigolds have been found to be a wonderful deterrent to mosquitoes. They are also one of the few plants that are most effective in their herbal form.

During their natural biological processes, marigolds produce chemicals, namely pyrethrum and thiophenes, that are unpleasant to mosquitoes and other summer pests. These chemicals can be released when these lovely plants are crushed and marigold essential oil is produced. But they are also highly effective in the garden and often deter mosquitoes as well as artificial sprays.

Wandelröschen – beautiful and effective against the pests.

One of the most effective flowers against mosquitoes is the wood anemone. This beautiful bedding plant is often used in the garden because of its beauty and ability to attract bees. However, this is not all that the plant can do. Several studies have demonstrated the flower’s effectiveness in repelling mosquitoes.

Wandelröschen can be planted well in beds, but it is best to display them in heavily used areas where they can be disturbed. When the plant’s leaves and flowers are rubbed or crushed, they give off a strong citronella scent that deters mosquitoes. You can also cut them and incorporate them into cut flower bouquets to bring their beauty and superpowers indoors.

Another surefire way to repel mosquitoes is to dry, shred and burn the leaves. However, don’t rub the crushed Wandelröschen leaves on your skin as the oil can irritate it.

Does basil also help against mosquitoes?

In recent years, studies have shown that the compounds contained in basil are extremely toxic to mosquitoes and their larvae. Basil oil is the most effective mosquito deterrent, but plain basil leaves are also very effective.

While other plants may be better suited to repel pesky mosquitoes, basil is a good choice for anyone looking for a multipurpose plant for their herb garden.

Fighting mosquito infestations in the garden with the power of mint

Mint also finds its place in the list of herbs against mosquitoes. The strong mint scent of all mint varieties effectively repels many pests, with peppermint being the most effective variety. Studies have shown that peppermint, when applied as an oil, can deter mosquitoes for between 45 minutes and 2 hours.

But you don’t have to make mint essential oil to take advantage of this herb’s mosquito-repelling properties. Fresh mint works wonders, and you can easily make a mint spray for yourself or for an area that is prone to pests. Simply crush some fresh mint leaves and steep them in boiling water. Once it cools, strain the water and pour your mint mixture into a spray bottle.

These plants are completely useless against mosquitoes

They are often touted as effective, but their action against biting insects has not been scientifically confirmed. Here are the plants that, despite their reputation, are useless against a plague of mosquitoes in the garden.

  • Rosemary: this herb in a real asset in the herb garden, but unfortunately can not drive away mosquitoes from your garden or terrace.
  • Garlic: While studies have shown that rubbing garlic on the skin has some success in deterring mosquitoes, the plant itself has no repellent properties. However, the plant itself has no repellent effect on mosquitoes.
  • Scented geraniums: Still known as the citronella plant, scented geraniums ironically have no proven effect against mosquitoes.
  • Liverwort: Although touted as an effective mosquito repellent plant, there is no research to confirm the defenses of the pretty purple flower against mosquitoes.
