Hornworms are as unappealing as their name suggests.
These nasty insects can grow up to four inches long and have characteristic horns at the rear end. Because of their appearance, people ask a question about do hornworms bite.
They can quickly destroy a tomato patch and consume various other garden vegetables.
However, you can prevent hornworms from destroying your valuable plants if you follow some preventive measures and act quickly when they appear.
What exactly are hornworms?
Hornworms are the larvae of the hummingbird or sphinx moth, which derives its name from its rapid wing beats.
If you spot these whirling moths hovering in the air and sucking nectar from the flowers in your garden, look out for horned caterpillars.
There are several types of the hornworm. The horn of the tomato hornworm is black that of the tobacco hornworm is red.
They feed on tomatoes and tomato-like plants such as peppers and potatoes.
The adult moths lay their eggs on plant hosts. They not only infest tomato plants but some vegetables.
When the hornworm eggs hatch, they begin to feed. An adult caterpillar of the hornworm can eat an entire tomato plant within two days.
How can you protect yourself from hornworms?
Adult moths lay their eggs on several weeds in the tomato family, such as horse saddle, jimson weed, and nightshade. Keep these weeds out of your garden.
They harbor so many pests of the tomato plant family that you should remove them from your garden if they are present.
Numerous predatory insects prey on tomato hornworms. Ladybirds and lacewings feed on worm eggs and larvae. A small wasp species lays its eggs under the insect’s skin; once the eggs hatch, the larvae feed on the hornworm.
To encourage beneficial insects, limit the use of pesticides. Grow a wide range of flowering plants, especially sweet lettuce.
Also, allow some vegetable and herb plants to flower, such as lettuce, parsley, and broccoli. Beneficial insects love the nectar these flowers provide.
How can hornworms be controlled?
As a rule, hornworms can be controlled by picking them off the plants by hand and removing them. This is because hornworm populations are usually small (the horn is harmless). Throw them in soapy water or feed them if you have chickens.
If you do not want to deal with worms, pollinating or spraying plants is the best alternative.
Repellents contain both synthetic and natural ingredients. The former is a high-risk measure with quick and definitive success.
The pests are eradicated from your garden. Unfortunately, the adverse effects are serious.
The pollutants contaminate the soil, plants, and water. Of course, the product comes with instructions on using it correctly and safely.
If you discover a hornworm with white oval appendages on its body, you should not remove it from the garden.
The white parts are cocoons that a wasp has parasitized. The wasps hatch from the cocoons and infest other hornworms.
The tomato and tobacco hornworm can be significant garden pests.
However, you can limit the damage with a few preventive measures and quick action when they appear.
Hornworms bite, sting, and poison
Hornworms can neither bite nor sting, so they pose no danger to humans.
The stinger that protrudes from their hindquarters may appear dangerous, but it is relatively harmless.
The caterpillars flee and hide rather than engage in a fight. Those insects are easy prey for their natural enemies, such as birds and small rodents.
Can they be touched? The answer is yes.
Tomato hornworms do not bite, even though their horn looks intimidating.
They will most likely squirm and wriggle away. Many people breed them as pets or as food for their reptiles.
If possible, avoid physical contact and wash your hands afterward.
Note that hornworms can exude a brown substance if you try to touch them. This substance is also known as “tobacco juice” and is used to deter predators.
Use gloves to protect your skin from these excretions, and wash your hands with soap afterward. Avoid touching your eyes, nose, or mouth. Use common sense.
Are some hornworms poisonous to animals and pets?
Hornworms are potentially toxic to dogs. Hornworms ingest a significant amount of toxins by eating tobacco leaves and tomatoes.
If your dog accidentally eats a hornworm, it may be poisonous to him. Occasionally, the toxin from the hornworm can be fatal to a dog.
Hornworms can affect cats in a similar way to dogs. The situation is similar to that of dogs. In general, cats are more sensitive eaters than dogs.
Therefore, the chemicals contained in hornworms can be dangerous for your cats.
In addition, swallowing any bug or insect can cause pain and suffering to your cat. Therefore, the answer is yes. Hornworms are poisonous to cats.
Chickens are notorious for devouring bugs and insects, and hornworms are one of their favorite foods.
Although hornworms are poisonous, they do little harm to chickens. To compensate for the toxicity of the hornworm, chickens have a strong digestive system.
If you decide to feed hornworms to your chickens, make sure that the number of hornworms they eat is limited.
