Home remedies to kill pests in your vegetable garden

 

Urban gardening is a rewarding experience that connects us with nature and provides us with fresh and healthy food. However, one of the most common challenges we gardeners face is finding home remedies for pests that can affect our plants.

These unwanted invaders can ruin our crops if not properly controlled. But don’t worry, here are some cheap and effective ecological remedies for the most common pests in your urban garden, as well as the types of crops they can be found on.

Aphids

Aphids are small insects that feed on plant sap, causing leaf deformities and weakened growth. They are commonly found on crops such as tomatoes, peppers, lettuce and many leafy green plants.

Remedies to combat this pest:

  • Insecticidal soap: Mix one tablespoon of natural liquid soap in one litre of water and spray on affected plants. The soap will suffocate the aphids without harming your plants.
  • Garlic and vegetable oil: Mix several cloves of crushed garlic in a tablespoon of vegetable oil and let it sit overnight. Then strain the mixture and dilute it with water before spraying on plants.

Mites

Mites are tiny arachnids that feed on plant leaves, leaving yellow spots and webs on the surface. They can be found on crops such as strawberries, green beans, cucumbers and many leafy plants.

Ecological remedies to get rid of spider mites:

  • Neem oil: Mix one teaspoon of neem oil in one litre of water and spray on affected leaves. It acts as a natural repellent and also interferes with the life cycle of the mites.
  • Soap and water: Simply spray the affected plants with strong water from the garden hose to physically remove the mites. If necessary, you can add a few drops of liquid soap to the water to improve effectiveness.

Caterpillars

Caterpillars can quickly devour the leaves of your plants, causing serious damage in a short time. They can be found on crops such as cabbage, broccoli, cauliflower and other plants of the cruciferous family.

Tips to get rid of caterpillars in your garden:

  • Hand picking: Inspect your plants regularly and collect caterpillars by hand with a glove. Then place them in a container with soapy water to remove them.
  • Bacillus thuringiensis: This is a biological insecticide that kills caterpillars when ingested. You can find it in powder or liquid form in garden shops and follow the application instructions.

Snails and slugs

These molluscs can be a nuisance in your urban garden, especially during the wet months. They can be found on crops such as lettuce, spinach, strawberries and many tender leafy plants.

Inexpensive remedies to get rid of snails and slugs:

  • Homemade traps: Place containers of beer or wet boards at ground level to attract and trap snails and slugs.
  • Natural barriers: Surround your plants with crushed eggshells or diatomaceous earth to create a barrier that is difficult for them to get through.

Whitefly

Whitefly is a small insect that feeds on plant sap and can transmit viral diseases. They can be found on crops such as aubergines, pumpkins, tomatoes and many plants of the Solanaceae family.

Tips to combat whitefly:

  • Garlic and pepper solution: mix several cloves of garlic and a teaspoon of pepper in a litre of water and let it sit overnight. Then strain the solution and spray on affected plants.
  • White vinegar: Mix one part white vinegar with three parts water and spray on infested plants to repel whiteflies.

Aromatic Plants against Pests

Aromatic plants not only add a touch of fragrance and beauty to your urban garden, they also play a crucial role in natural pest control. Their intense aroma acts as a natural repellent to many common pests, making them valuable allies in the fight against infestations.

Basil, for example, is known for its delicious aroma and its ability to repel mosquitoes, whiteflies and aphids. As well as being a popular ingredient in the kitchen, it can help protect your plants from pests.

Rosemary, with its herbal fragrance, is effective in repelling moths and carrot flies. Mint, with its refreshing aroma, repels ants, aphids and spiders, while lavender, with its fragrant purple flowers, is effective against flies, mosquitoes and moths.

By interspersing these plants among your crops, you will be creating a natural barrier against potential pests. In addition, these aromatic plants also attract beneficial insects, such as bees and ladybirds, which help control pest populations.

Remember that prevention is key to keeping invasions of your urban garden at bay. Keep your garden clean and tidy, regularly remove weeds and diseased plants, and encourage biological diversity to attract natural enemies of pests.
