Baby grubs are the babies of many different kinds of beetles, moths, and butterflies. They’re pretty small and usually look white or cream-coloured, with a long, round body shape. 

Unlike grown-up bugs, they don’t have legs or wings, and you can’t see their head when you look down at them.

Now, What do baby grubs eat? Well, they mostly munch on plant roots and stuff like that in the soil. 

But here’s the catch: some types of grubs can be real troublemakers for farmers and gardeners because they can wreck crops and plants.

Knowing what baby grubs prefer to eat isn’t just interesting; it’s important for keeping their numbers in check. 

When springtime comes, these hungry little critters start chowing down again, gobbling up everything in sight until they grow up.

In this article, we’ll talk about what baby grubs enjoy eating, what Chafer grubs eat, and where they prefer to be, and we’ll also explore their life cycle along with some interesting facts about these small bugs that live underground.

What Do Baby Grubs Eat: Baby Grub’s Favorite Foods


Baby grubs, also known as larvae, represent the immature stage of various beetle species. 

Their dietary preferences vary depending on the specific type of beetle they are destined to become. 

Generally, most grubs fall into two categories: herbivores, which consume plants, and detritivores, which feed on decomposing organic matter.

Among the numerous species of baby grubs, such as Chafer grubs and Leatherjackets, many exhibit a penchant for devouring plant roots

They tunnel into the soil, targeting the delicate roots of grass, flowers, and other vegetation

This feeding behavior can result in considerable damage to lawns, gardens, and crops.

Besides, baby grubs help keep the environment healthy by eating up rotting organic stuff in soil and compost piles. 

This helps break down dead plants, recycle nutrients, and make the soil better for plants to grow in.

Occasionally, baby grubs may also nibble on the tender shoots of grass and other plants.

This consumption pattern can lead to visible harm to turf and vegetation, especially in areas with a high concentration of grubs.

What do Chafer grubs eat?

Chafer grubs are baby scarab beetles often found in lawns, gardens, and farms. There are different types of chafer grubs in these places. 

These little grubs love eating, especially plant roots. They have chubby bodies and brown heads. 

They mainly eat the roots of grass, flowers, and other plants. This can cause big problems for lawns and gardens because they eat up the roots that plants need to grow.

What do Leatherjackets eat?

Leatherjackets, on the other hand, are the larval stage of crane flies. These long, greyish-brown critters are often found in damp soil, especially in grassy areas.

Unlike Chafer grubs, they don’t have legs and their skin is tough and leathery. They eat differently too. 

Leatherjackets mostly feed on dead stuff in the soil, like old leaves and plants. But sometimes they also nibble on grass roots and other plant roots. 

While this helps break down dead stuff in the soil, which is good for the soil, it can also harm lawns and farms.

Where Do Baby Grubs Live: The Habitat of Baby Grubs

Baby grubs, which are the early stage of beetles, have different preferences for where they live depending on what kind of beetle they will turn into later. 

Most grubs like to live in the soil, where they dig tunnels to find food. 

For example, Chafer grubs and June beetle grubs usually live in soil with lots of healthy grassroots because they eat those roots. 

Other grubs, like Scarab beetle grubs, prefer places with a lot of rotting stuff, like compost piles or manure heaps, because they help break down that stuff. 

Some grubs even make their home in old, rotting wood, like Stag beetle grubs, and help break it down too. 

But there are many different kinds of grubs, and some might live in different places like under leaves, in old logs, or even in water.

Life Cycle of Grubs

Grubs, just like many other insects, go through a complete makeover during their lifetime. It’s like they have four different identities: egg, larva (which we call grub), pupa, and adult.

1. Egg: It all starts when adult beetles lay their tiny white eggs in the soil, usually in the warmer months. These eggs take a few weeks to hatch.

2. Larva (Grub): This stage is all about eating! Grubs have soft bodies and look like they’re bending into a C-shape. 

They spend most of their time munching away, either on plant roots or on dead stuff in the soil, depending on the type of grub they are. 

Some, like chafer grubs and June beetle grubs, love to snack on plant roots, while others, like scarab beetle grubs found in compost piles, prefer eating dead and decaying stuff. 

When winter comes, they burrow deeper into the soil to keep warm.

3. Pupa: When a grub is all grown up, it builds a cosy chamber in the soil called a pupal chamber. 

Inside this chamber, it transforms into a pupa, which is like a resting stage. The pupa doesn’t move or eat and stays like this for a few weeks.

4. Adult: Finally, the adult beetle breaks out of its pupal shell and emerges. This is the stage we’re most familiar with, where beetles have hard bodies and wings. 

Now they’re ready to find a mate and start the cycle all over again by laying eggs. And so, the life cycle continues!

Interesting Facts About The Baby Grubs


Baby grubs might be tiny and easy to miss, but they have some pretty cool qualities that make them stand out in the bug world:

1. Helping Hands in the Soil

Baby grubs are like little gardeners underground. As they dig and tunnel through the soil, they help make it healthier by mixing things up and making sure nutrients can move around better.

2. Nature’s Clean-up Crew

Lots of baby grubs love snacking on old, dead stuff in the soil. This might not sound glamorous, but it’s super important because it helps break down all that dead plant stuff and makes the soil richer.

3. Winter Survivors

When it gets super cold, baby grubs know how to handle it. They dig down deeper into the soil where it’s warmer, kind of like how we snuggle under blankets when it’s chilly. 

Some of them even have a special ability to avoid freezing!

4. Part of the Food Chain

Baby grubs aren’t just sitting ducks waiting to be eaten. They’re part of a big food game in nature. 

Birds, mammals, and other bugs think they’re pretty tasty, so they help keep the balance of who eats who in check.

5. Lots of Different Types

There are all kinds of baby grubs out there, each with its own way of living. 

Some hang out in lawns and gardens, while others prefer compost piles or rotting wood. They’ve learned to adapt to all sorts of homes.

6. Money Matters

While some baby grubs are helpful, others can be a real pain for farmers and gardeners.

Certain types, like Chafer grubs and Leatherjackets, can mess up lawns, crops, and plants, causing headaches and money losses.

So, even though they’re small, baby grubs play a big role in keeping nature in balance.

Whether they’re digging in the dirt, munching on old stuff, or being part of the food chain, they’re worth keeping an eye on!


To sum up, even though baby grubs might not catch your eye right away, they do some pretty important stuff in nature. 

They can affect how plants grow and how farms work. So, it’s really important to know what they eat, where they live, and how they grow. 

This helps us take care of plants better and make sure our ecosystems stay healthy.


What can you feed grubs?

Grubs typically eat things like plant roots, decaying organic matter (like leaves and dead plants), and sometimes even the tender shoots of grass or other plants.
They’re like tiny recyclers, breaking down old stuff to help keep the soil healthy.

What do baby grubs look like?

Baby grubs, or larvae, can vary in appearance depending on the species, but they usually have soft, C-shaped bodies.
They might be white, creamy, or greyish, and some have brown heads. They’re not very big, usually just a few centimeters long.

How fast do grubs grow?

Grubs grow at different rates depending on factors like species, temperature, and food availability.
Some may take only a few weeks to reach maturity, while others might take a year or more.
Generally, they grow slowly, gradually molting and getting bigger until they’re ready to pupate and become adult beetles.
