Plants can be good helpers in pest control in open areas and in the home. In the article we will talk about crops that have the ability to repel insects, we will give tips on their placement in the garden, in the garden and growing indoors.
What are repellent plants
Most insects rely on smell in search of food and breeding grounds. Repellent plants have a strong scent that can confuse small pests.
Released into the environment, phytoncides have an irritating and depressing effect on insects that cannot stand such a neighborhood and go in search of a new territory..
Fighting flies and mosquitoes
Pesky flies and mosquitoes can significantly spoil summer vacations in the country, especially if it is located near a reservoir. You can limit the number of annoying insects using the following plants.
Castor oil plant. A tall African shrub can be planted next to an artificial pond – mosquitoes do not tolerate its smell, and spectacular palm-lobed leaves will add originality and exoticism to the garden landscape.
Important! Castor bean seeds are very poisonous, so the plant is not recommended to be planted in summer cottages where there are small children and pets.
Tansy (“Field Rowan”) Contains essential oil, the smell of which repels mosquitoes and flies. The plant is not very attractive, so it is better to place it in remote corners of the site..
Ruta – perennial fragrant grass with a pungent odor, most effective in the fight against flies. In extreme heat, the leaves secrete a large amount of flavonoids, which can irritate and even burn the skin. Given this feature, the root should be planted away from home, the optimal place is near a manure or compost heap.
In the flower arrangement near the entrance to the house, you can include nasturtium, and plant fragrant around the gazebo rosemary, which repels mosquitoes and is used in cooking.
It has phytoncidal properties and Walnut. To plant it on the site, you will have to select the brightest place and provide a deep fertile soil layer (at least 90 cm).

How to protect your home from moths, cockroaches and aphids
Not the most pleasant neighbors that can live next to a person are cockroaches, moths and aphids. Some indoor flowers and shrubs have a good resistance to domestic pests..
Geranium (Pelargonium) – an unpretentious plant that lives on windowsills, balconies and greenhouses. The flower drives away flies, aphids and disinfects the room.
Important! It is better to “settle” Pelargonium on the veranda, in the kitchen or living room. She has no place in the children’s room, as she can become a strong allergen for a child..
Smell fragrant woodruff scares off cockroaches. An ornamental shrub with white flowers looks beautiful in hanging planters and floor pots. After the plant has completed its mission, it can be transplanted into open ground.
A well-known anti-moth remedy – lavender. The peak of the action of fungicides occurs at the time of flowering of the herbaceous plant, after which the protective properties of lavender fade away.
When growing lavender in a pot, you must adhere to the basic rules for caring for it:
- the plant prefers well-lit places;
- the size of the pot should be 2–4 cm larger than the root ball;
- the presence of large drainage holes in the container – lavender does not like waterlogging;
- the soil is “fluffy” and light (1 tablespoon of lime can be added to a 10 liter pot);
- water the lavender as the soil dries.
Important! Once dry and dehydrated, lavender will no longer bloom.
It will help to protect the house from aphids, moths and mosquitoes spicy basil. Indoors, it is better to grow small-leaved varieties such as Marquis and Clove Scent. It is better to plant basil with seeds in April; long boxes or ordinary flower pots are suitable for planting.
Attention! Basil is a thermophilic plant that prefers a more or less stable temperature regime. If you equip a “bed” on an open balcony, then when it gets cold, the plant must be covered with cellophane film.

Protection of garden and horticultural crops
To control pests in the garden, satellite plants are sown in the aisles, which will distract insects from cultivated plantings. In the garden around the trees, you can place fragrant herbs or arrange a flower bed of repellent flowers.
The choice of this or that “defender” will depend on the pest and the type of garden culture.

Important! It is better to plant repellent plants between garden beds in small islands or along the perimeter of the site so that they do not compete and do not drown out the main crops.
Cultural repellent plants: mixed plantings
Mixed planting means combining different garden crops on the same bed. This method has several advantages:
- the reproduction of pests and diseases is inhibited – the search for a “host plant” becomes more difficult;
- crops are placed in the soil more densely – the risk of the spread of pests that lay eggs on the ground is reduced;
- some plants are effective protectors for each other.
The correct options for the “neighborhood” of garden crops:
- Crops of tomatoes and collard greens. The smell of tomato leaves will scare away aphids, leaf beetles and cruciferous fleas.
- Celery will protect the crop from spring cabbage fly.
- Garlic should be placed near currant and strawberry bushes – it will reduce the population of kidney mites.
- Tomatoes near the gooseberry will scare away moth and sawfly from the bush.
- It is necessary to plant beans in the aisles of the potatoes – the plant will drive away the Colorado beetles.
- Radish will protect pumpkin from glass bowls.
- Dill will “take away” white butterflies from turnips and cabbage.
Supporters of “crop without chemistry” actively use the properties of natural repellents, planting them between garden beds, garden trees, shrubs, growing at home to fight cockroaches, aphids and moths.
