The Power of Trap Crops: An Innovative Approach to Agricultural Pest Control

As the world’s population continues to grow, the demand for food production also rises. This has led to an increase in the use of pesticides and insecticides to protect our crops from pests. While these methods can be effective, they come at a cost to the environment, our health, and the quality of our food.

Fortunately, there is a safer and more sustainable way to protect our crops: trap crops. Trap crops are plants that are strategically placed to attract pests away from the main crop, reducing the damage caused by pests without the use of harmful chemicals.

What are Trap Crops?

Trap crops are plants that are intentionally grown to lure pests away from the main crop. These crops can be planted close to or around the crop that needs protection, or they can be grown as a barrier crop around the field.

The idea behind trap crops is simple: pests are attracted to specific plants for food or shelter. By planting a crop that is more appealing to the pest than the main crop, the pest will be drawn to the trap crop instead of the crop that needs protection.

Benefits of Trap Crops

There are several benefits to using trap crops as a method of pest control:

  • Reduced use of harmful chemicals on crops, lowering environmental damage and health risks to workers and consumers.
  • Inexpensive and easy to implement
  • Can effectively reduce pest populations and protect crops without affecting the yield or quality of the main crop.
  • Trap crops can enhance the diversity of the agricultural system, providing additional benefits to wildlife and soil health.

Types of Trap Crops

There are different types of trap crops that farmers can use depending on their specific needs and the pests they are trying to control. Some examples include:

  • Attractive crops: These are the crops that pests are most attracted to and are planted to lure pests away from the main crop. For example, sunflowers can be planted to attract stink bugs away from tomatoes or peppers.
  • Repellent crops: These are crops that pests do not like and can be planted to create a barrier around the main crop. For example, planting garlic around roses can help repel aphids.
  • Sacrificial crops: These are crops that are planted with the purpose of being destroyed by pests. By providing an alternative food source, these crops can protect the main crop from severe damage. For example, planting a small patch of sweet corn away from the main crop can lure corn earworms away from the main corn field.

Concluding Thoughts on Trap Crops

Trap crops offer a sustainable and effective alternative to traditional pest control methods. By using natural plant defenses to lure pests away from crops, we can reduce the use of harmful chemicals while maintaining high yields and crop quality. Additionally, trap crops can provide environmental benefits by enhancing biodiversity and improving soil health.

As farmers and consumers become increasingly concerned about the health and environmental effects of traditional agricultural practices, trap crops provide a promising solution for more sustainable pest control.

FAQs About Trap Crops

What plants make good trap crops?

Good trap crops are highly attractive to pests and are planted near the main crop. Depending on the pest in question, different crops can be used as trap crops. For example, marigolds and sunflowers are good trap crops for stink bugs, while clover and buckwheat can attract aphids.

How do I know if I need to use trap crops?

If you have experienced significant pest damage in previous growing seasons, or if you are located in an area with a high prevalence of pests, using trap crops can be an effective way to reduce damage to your main crops.

Will using trap crops affect my yield?

When used properly, trap crops should not have a significant effect on the yield or quality of the main crop. In fact, using trap crops can improve the overall health of the agricultural system, leading to greater yields over time.

Are trap crops expensive to implement?

Trap crops can be a cost-effective alternative to traditional pest control methods. The cost will depend on the specific crop used and the size of the field, but trap crops are generally less expensive than insecticides and can provide long-term benefits to soil and plant health.

Where can I learn more about using trap crops?

There are many resources available for farmers interested in using trap crops. Local agricultural extension offices can provide advice on specific pests and crops, and there are many online resources and books available on the topic.


With the growing awareness of the impact of traditional pest control methods on the environment and human health, using trap crops is an innovative approach to agricultural pest control that benefits both farmers and consumers. By reducing the use of harmful chemicals and enhancing the natural defenses of crops, trap crops provide a sustainable and effective way to protect our food supply.
