What Are The Little Bugs on My Corn Plant

Updated: June 20, 2022

If you have noticed tiny bugs on your corn plants, it’s essential to identify them and take necessary action if they are harmful. In this article, we will discuss the little bugs that can infest your corn plant, how to identify them, and what to do if they pose a threat.

Types of Bugs that Infest Corn Plants

1. Corn Earworms

Corn earworms are the most common insect pests that affect corn plants. The larvae of these moths feed on the silks and kernels of corn ears, leading to stunted growth and reduced yield. These pests are usually found during late summer or early fall.

2. Corn Borers

Corn borers are another type of moth larvae that burrow into the stalks of corn plants. Their feeding activity results in stunted growth and reduced yield. Adult corn borers are small, slender moths with a wingspan of about an inch.

3. Aphids

Aphids are tiny, pear-shaped insects that suck sap from the leaves of corn plants. These pests can multiply rapidly and cause yellowing and curling of leaves, leading to reduced photosynthesis and growth.

4. Spider Mites

Spider mites are another common pest that can infest corn plants. These tiny arachnids feed on the sap of leaves, causing yellowing and stippling of foliage. Severe infestations can result in defoliation and reduced yield.

How to Identify Bugs on Your Corn Plant

To identify the bugs on your corn plant, you need to examine the plant closely. Look for any signs of damage on the leaves, stalks, or ears of corn. You may also notice some small insects crawling or flying around the plant.

To get a closer look at these insects, use a magnifying glass or take a photo and zoom in. This will help you identify the pest and take appropriate action.

What to Do if Bugs Pose a Threat to Your Corn Plant

If you notice an infestation of bugs on your corn plant, it’s vital to take prompt action to prevent damage to your crop. Here are some steps you can take:

  • Remove any damaged or infected parts of the plant and dispose of them.
  • Use insecticidal soap or neem oil to treat the infested plant.
  • Introduce natural predators like ladybugs, lacewings, or parasitic wasps to control the pest population.
  • Practice crop rotation and maintain good soil health to prevent future infestations.


How do I prevent bugs from infesting my corn plants?

You can prevent bugs from infesting your corn plants by maintaining good soil health, practicing crop rotation, and using natural remedies like neem oil or insecticidal soap.

Can I use chemical pesticides to control pests on my corn plants?

While chemical pesticides may be effective in controlling pests, they can harm beneficial insects and contaminate the soil. It’s best to use natural remedies or integrated pest management techniques to control pests.

How do I know if the bug on my corn plant is harmful?

You can identify harmful bugs by examining the damage they cause to your plant. Look for signs of stunted growth, yellowing leaves, or damaged ears of corn. If you’re unsure, consult a gardening expert or agricultural extension office for advice.

In conclusion, identifying and controlling bugs on your corn plant is crucial for the health and yield of your crop. By following these tips and taking prompt action, you can prevent damage and ensure a healthy harvest.
