What are garden pests?
Garden pests are insects or other organisms that can cause damage or harm to plants, which can negatively affect their growth, health, and yield. Some common types of garden pests include aphids, slugs, snails, spider mites, whiteflies, caterpillars, beetles, and many more.
These pests can cause various types of damage to plants, such as eating leaves, stems, or roots, transmitting diseases, and sucking out plant juices. Some pests can even attract other pests or predators to your garden, which can cause further damage. These pests can have negative effects on your plants by:
- Feeding on plant tissues can weaken or kill the plants.
- Spreading diseases that can infect the plants and reduce their productivity.
- Disrupting the growth and development of the plants.
Here are some common garden pests that plants can deter:
- Aphids: These tiny insects suck the sap from the leaves and stems of plants, causing them to wilt and die. Plants like marigolds, chives, and garlic can deter aphids.
- Caterpillars: These larvae of moths and butterflies can eat the leaves and flowers of plants. Plants like dill, parsley, and fennel can repel caterpillars.
- Slugs and snails: These slimy creatures can eat large holes in leaves and fruits, and they can also spread diseases. Plants like lavender, sage, and thyme can deter slugs and snails.
- Beetles: These insects can chew through the leaves and flowers of plants. Plants like basil, catnip, and tansy can deter beetles.
- Rodents: These pests can eat the roots and fruits of plants, causing extensive damage. Plants like peppermint, garlic, and onions can repel rodents.
By incorporating pest-repellent plants into your garden, you can deter these pests and protect your plants from damage.

How to incorporate pest-repellent plants in your garden
Incorporating pest-repellent plants in your garden is a great way to protect your crops from pests naturally. Here are some ways to integrate pest-repellent plants in your garden:
- Companion Planting: Companion planting involves planting different plants together that complement each other’s growth and properties. For example, planting marigolds alongside tomatoes can help deter aphids and whiteflies, while also improving the soil quality for the tomatoes.
- Intercropping: Intercropping involves planting different crops together on the same plot of land. This method can help reduce pest damage by confusing pests or making it harder for them to find their preferred plants. For example, planting onions or garlic with carrots can help deter carrot flies and improve the carrots’ growth.

For example, planting basil or oregano alongside your tomato plants can help repel pests like tomato hornworms and attract bees to pollinate the tomato flowers.
- Container Planting: If you have limited space, you can still incorporate pest-repellent plants in your garden by planting them in containers. This can also make it easier to move the plants around if necessary. For example, planting mint or petunias in a container on your balcony can help repel mosquitoes and aphids.
When incorporating pest-repellent plants in your garden, it’s important to choose plants that are appropriate for your climate and soil conditions.
You should also pay attention to the plant’s growth habits and spacing requirements to ensure that they have enough room to grow and thrive. By using a combination of these methods, you can create a natural and effective pest management strategy for your garden.
