The primary bugs found on corn on the cob are thrips and various types of worms.
Common Pests on Corn on the Cob
When inspecting fresh corn on the cob, it's common to encounter small insects and larvae. These pests are typically found nestled between the kernels of corn or crawling on the inside part of the husk. While the outer husks are usually discarded and the cob is often thoroughly rinsed, there is a possibility that these tiny organisms might still make their way and remain lodged between the kernels.
Here's a closer look at the common culprits:
- Thrips: These are incredibly tiny, slender insects, often less than a millimeter long, making them very difficult to spot with the naked eye. They can be light-colored or dark and are known to hide in tight spaces, such as between corn kernels or within the folds of the husk. Their presence might appear as small, moving specks.
- Worms: In the context of corn, "worms" typically refer to the larval stages of various moths. These caterpillars can vary in size and color depending on the species. Common types include the corn earworm, European corn borer, and fall armyworm, which feed on the kernels and silk. They are often more noticeable than thrips due to their larger size.
Identifying and Handling Infested Corn
Identifying pests on corn requires careful inspection. While some bugs are easily visible, others, especially thrips, might need closer attention.
Quick Inspection Guide
| Pest Type | Appearance | Common Location (on corn) |
|---|---|---|
| Thrips | Tiny (often <1mm), slender, dark specks | Between kernels, inside husk |
| Worms | Larval stage (caterpillars), variable size/color | Between kernels, at the tip, inside husk |
Steps for Cleaning Corn on the Cob
Even if you don't immediately see pests, it's always a good practice to thoroughly clean corn before cooking.
- Peel Back Husks: Carefully peel back the husks to expose the kernels.
- Remove Silks: Strip away all the silk threads from the cob. Pests, especially worms, often hide among the silks or at the tip of the cob.
- Inspect Thoroughly: Examine the cob meticulously, paying close attention to the spaces between kernels and the base of the cob. Look for any discoloration, tiny moving specks, or visible worms.
- Rinse Under Running Water: Hold the cob under cold, running water, scrubbing gently with your fingers or a soft brush to dislodge any remaining pests or debris. This helps ensure cleanliness before consumption.
- Cut Away Damaged Areas: If you find any areas that have been significantly chewed or damaged by pests, it's advisable to cut them away.
