You will learn what it is, how it lives, and why it’s important to keep apples safe from it.
The apple worm may seem like a simple bug, but it plays a big role in the world of fruits. If you like apples, it’s good to know what causes those little holes in them. Knowing about the apple worm can help you understand how fruits grow and what makes them healthy or not. Let’s explore this topic together with easy words and clear facts.
What is an Apple Worm?
An apple worm is not a type of worm like an earthworm. It is usually a baby insect, like the larva of a moth. It is also called a caterpillar. The most common apple worm is the codling moth larva. This tiny baby moth is white or pinkish and has a brown head. It is small but very hungry.
The apple worm hatches from eggs that the mother moth lays on apples or leaves. When the eggs hatch, the baby worm starts to eat. It chews its way inside the apple to stay safe and full. The apple worm loves the sweet taste of the fruit.
Where Do Apple Worms Come From?
The mother moth flies around apple trees in spring and summer. She lays tiny eggs on the apples. These eggs are so small that people often don’t see them. After a few days, the eggs hatch, and the apple worm comes out. It begins to eat the skin and go inside the apple.
The apple worm stays inside the apple to hide from birds or people. It eats and grows there until it is ready to come out. Then it leaves the apple, drops to the ground, and becomes a moth later. So, the life of an apple worm begins and ends with apples.
Why Are Apple Worms Bad for Apples?
The apple worm makes holes inside apples. These holes are small but make the apple rot faster. If you see a soft or brown spot in an apple, it may be caused by the worm. When apples have apple worms, they are hard to sell. No one likes eating apples with bugs inside.
Farmers work hard to grow apples. But when the apple worm attacks, many apples go to waste. This costs money and time. A single apple worm can ruin many apples during one season. That’s why people try hard to stop the apple worm early.
How Do Farmers Stop Apple Worms?

Farmers watch their apple trees closely. They check for signs of the apple worm like holes, soft spots, or droppings. They may use traps to catch the moths before they lay eggs. Some use sticky bands on tree trunks. This stops the baby worms from going back up the tree.
There are also sprays that can keep the apple worm away. These sprays are safe for people but not for bugs. Some farmers use natural ways like helpful insects. These good bugs eat the moth eggs before they become the apple worm. This keeps the apples safe without using too many chemicals.
How to Know If an Apple Has a Worm
It’s easy to spot a bad apple. If you see a small hole on the apple skin, it may have an apple worm inside. That’s the entry hole. You may also see brown spots or tunnels. Sometimes, the apple may feel softer in one area. This is where the apple worm is hiding.
When you cut an apple open, check the core. If you see a tiny white or pink worm, that’s the apple worm. You may also find a trail of brown stuff. That’s a sign the worm has been eating. It’s best not to eat apples that have a apple worm inside.
What Happens to the Worm After It Leaves the Apple?
Once the apple worm is full, it crawls out of the apple. It drops to the ground and hides in the dirt. There, it makes a shell called a cocoon. Inside the cocoon, the worm changes into a moth. This takes a few weeks or months, depending on the season.
After the moth comes out, it starts the cycle again. The moth flies to an apple tree and lays more eggs. Soon, more apple worms hatch and eat new apples. This is why the apple worm problem never goes away unless people control it early.
Are Apple Worms Harmful to People?
The apple worm does not hurt people. It only eats fruit. If someone eats an apple with a worm, it won’t make them sick. But it is not fun to eat a worm by mistake. Most people throw the apple away if they see an apple worm inside.
Washing apples before eating can help remove the eggs or dirt. Cutting the apple helps you see if there’s a apple worm hiding inside. Most apples in stores are checked before selling. So the chance of finding an apple worm is small, but it can still happen.
