What are Cankerworms?

Cankerworms, also known as inchworms, are the larval stage of several moth species. These inch-long caterpillars are notorious for their defoliating habits, munching on leaves and causing significant damage to trees. While their impact on trees is undeniable, the question remains: are cankerworms dangerous to humans?

Are Cankerworms Dangerous to Humans? The Short Answer: Generally No

The good news is that cankerworms are generally not considered dangerous to humans in the sense that they don't bite or sting. Unlike some caterpillars, they lack venomous spines or stingers. They primarily focus on consuming foliage.

However, there are a few caveats to consider.

Potential for Skin Irritation

While cankerworms don't bite, their hairs or setae can sometimes cause minor skin irritation in sensitive individuals. This is similar to the reaction some people have to contact with certain plants. The irritation may manifest as a mild rash or itching. Thorough handwashing after handling cankerworms or plants infested with them is recommended.

Allergic Reactions

Some people might experience an allergic reaction to the cankerworm's hairs or saliva. This reaction could be more severe than simple irritation, potentially causing redness, swelling, or even breathing difficulties in rare cases. If you experience a significant allergic reaction after contact with cankerworms, seek medical attention immediately.

Indirect Dangers

The significant defoliation caused by cankerworm infestations can indirectly impact humans. This can negatively affect the environment, potentially impacting food sources and biodiversity, but this is an environmental concern rather than a direct human health risk.

How to Protect Yourself from Cankerworms

Prevention and proactive measures can help minimize any potential discomfort:

Wear gloves: If you need to handle cankerworms or remove them from plants, wear gloves to protect your skin.
Wash thoroughly: After working in areas with cankerworms, wash your hands and exposed skin with soap and water.
Monitor children and pets: Supervise children and pets to prevent them from handling cankerworms.
Professional pest control: For severe infestations, consider seeking professional pest control services. They have effective and safe methods for managing cankerworm populations.

Cankerworm Infestations: When to Seek Professional Help

While cankerworms aren't inherently dangerous, large infestations can severely damage trees. If you notice significant defoliation or large numbers of cankerworms in your yard, consider consulting an arborist or pest control professional. They can assess the situation and recommend appropriate treatment options to protect your trees.

Conclusion: Weighing the Risks

While cankerworms pose minimal direct danger to humans, it's crucial to practice caution. Simple preventative measures like wearing gloves and washing hands can prevent skin irritation. For severe allergic reactions or large-scale infestations, seek professional help. Understanding the potential risks, however small, allows for informed and responsible management.
