A few cloves of garlic buried in the soil
In the process of green plant maintenance, pest control has always been a major concern for plant lovers. Compared to chemical agents, natural plant pest repellent methods, with their advantages of being safe, environmentally friendly, and easy to operate, are becoming a new trend in home gardening. This article systematically analyzes five natural pest control methods, especially focusing on garlic, to teach you how to create a pest-free green space.
Principles and Application Scenarios of Garlic Pest Control
Double Effects of Allicin
Allicin contained in garlic has natural antibacterial and pest-repelling properties. Its pungent odor can effectively repel common pests such as aphids and red spiders, while also inhibiting the reproduction of soil bacteria, achieving dual effects of pest control and sterilization.
Garlic Water Preparation Process
Crush fresh garlic cloves and soak them in water at a ratio of 1:50 for 3 hours. The filtered solution can be directly sprayed on the leaves. It is recommended to apply twice a day, early morning and evening, for 3 consecutive days to completely eliminate aphid colonies.
Soil Improvement Solution
Bury 2-3 chopped garlic cloves shallowly on the surface of the potting soil, which can repel ants and nematodes, and slowly release nutrients. Remember to update every quarter to prevent garlic cloves from rotting and affecting the soil structure.
Complementary Plant Pest Control System
Leek Synergistic Pest Control
Crush 100g of fresh leeks and soak in 1L of water for 24 hours. The filtered solution can be sprayed to control red spiders. Alternating use with garlic can enhance the persistence of pest control. It is recommended to use both methods alternately twice a week.
Onion Complex Preparation

Chop 1/4 of an onion and soak in 500ml of water for 12 hours. The resulting solution has both leaf surface pest control and soil disinfection functions. It is especially suitable for easy-to-rot varieties such as succulents, with significant effects when applied twice a month.
Advanced Pest Control Solutions
Chili Pest Control System
Chili peppers soaked in a 1:500 solution are effective against scale insects, and boiling the chili water can increase the extraction rate of active ingredients. It is recommended to wear gloves during operation and avoid applying it during strong sunlight to prevent leaf burns.
Biological Trapping Technology
The mature pork skin ant trapping method needs to be combined with physical isolation measures: set a 20cm radius isolation zone centered on the flowerpot, place the bait, and concentrate on elimination after 6 hours. This method can achieve a root elimination rate of 92% for underground ant nests.
By systematically using a plant pest control system centered on garlic, combined with scientific application methods, it is possible to achieve green pest control in home gardening. It is recommended to establish a periodic control plan, combined with environmental regulation (maintaining ventilation, controlling humidity), to build a natural protective barrier, allowing plants to grow healthily without being troubled by pests.
