What Are Those Bugs? How to Identify Bugs in Quail Feed and Your Aviary

If you raise Coturnix quail long enough, eventually you may open a bag of feed, look inside a feeder, or clean your aviary and notice something moving.

Tiny white bugs.

Little brown beetles.

Something crawling around the feed bin.

Or, even more concerning, tiny dark specks moving through your quail's feathers.

The first reaction is usually the same:

What is that—and is it going to hurt my quail?

Not every bug found around a quail setup is a parasite. Some insects and mites are attracted to stored grain and feed, while others actually live on poultry or hide in the aviary and feed on the birds.

Knowing the difference is important because the solution depends entirely on what you are dealing with.

This guide will help you determine whether you have feed pests, aviary pests, or external parasites and what steps to take next.

First Question: Is the Bug in the Feed or on the Quail?

This is one of the easiest ways to start narrowing down the problem.

Bugs primarily inside feed

If the insects are concentrated inside:

• Feed bags

• Feed storage containers

• Feeders

• Cracked grain

• Spilled feed underneath cages

you are probably dealing with a stored-grain pest.

Common examples include:

• Grain mites

• Grain weevils

• Rice weevils

• Maize weevils

• Sawtoothed grain beetles

• Merchant grain beetles

  
  

Bugs primarily on your quail

If you see tiny insects or mites:

• Around the vent

• Under the wings

• Around the tail

• Along the breast

• At the base of feathers

• Crawling directly on the skin

  
  

you may be dealing with an external poultry parasite such as northern fowl mites or poultry lice.

Bugs hiding in the aviary

There is another important possibility.

Some poultry mites don't spend their entire lives on the bird.

The red poultry mite, also called the chicken mite or roost mite, hides in cracks and crevices during the day and comes out at night to feed on birds.

That means you could inspect your quail during the daytime and find very little while still having a mite problem in the aviary.

Common Bugs Found in Quail Feed

1. Grain or Flour Mites

Grain mites are one of the easiest pests for quail keepers to confuse with poultry mites.

They are not the same thing.

Grain mites live in stored grains and grain products rather than living as blood-feeding parasites on your birds.

What do grain mites look like?

Grain mites are extremely small, generally less than 1 millimeter long.

They may appear:

• White

• Cream colored

• Pale or translucent

• Like moving dust

When there are enough of them, it may look as though the surface of the feed itself is moving.

You may also notice:

• Fine dust

• Increased moisture

• A strange sweet odor

• Feed beginning to clump

  
  

Why are they there?

Warm temperatures and moisture create favorable conditions for many stored-feed pests.

For quail keepers in warm, humid climates, feed storage becomes especially important during summer.

A grain mite infestation can also be a warning that your feed has been exposed to moisture or poor storage conditions.

2. Grain Weevils

Weevils are small beetles that can infest stored grains.

Unlike tiny grain mites, weevils are usually much easier to see.

Look for:

• Small dark brown or black beetles

• A distinctive long snout

• Small holes in grain kernels

• Powder or fine dust accumulating in the feed

  
  

The holes are an especially useful clue.

Female weevils can deposit eggs in grain kernels, and the developing larvae feed inside the grain.

By the time you notice adult weevils crawling around, the infestation may already be established.

3. Rice Weevils

Rice weevils are similar to grain weevils but have a few identifying characteristics.

They are generally dark brown to reddish brown and may have lighter reddish markings on their bodies.

Unlike the grain weevil, rice weevils can fly.

Watch for:

• Small holes in grain

• Fine powder or dust

• Small beetles crawling through feed

• A musty smell

4. Maize Weevils

Maize weevils closely resemble rice weevils.

They are generally:

• Dark brown to nearly black

• Small

• Equipped with a noticeable snout

• Capable of flying

  
  

They can infest both growing crops and stored grain.

Like other weevils, they leave behind damaged kernels and fine grain dust.

5. Sawtoothed Grain Beetles

Sawtoothed grain beetles are small brown beetles with narrow, flattened bodies.

They get their name from the small saw-like projections along the sides of the thorax.

They particularly like:

• Cracked grain

• Broken kernels

• Processed grain products

Large infestations can contribute to heating and moisture problems within stored feed.

That becomes especially concerning because warm, damp feed creates conditions where mold can develop.

Is Bug-Infested Feed Safe for Quail?

This requires a little common sense rather than simply asking whether quail can eat insects.

Yes, quail naturally eat insects.

But that isn't really the problem.

An insect infestation may indicate that feed has been stored too long or under poor conditions.

Feed pests consume portions of the grain and can reduce its nutritional quality. More importantly, moisture associated with deteriorating feed can encourage mold.

That is where I become cautious.

I would discard feed if I notice:

• Visible mold

• Damp feed

• Significant clumping

• Unusual heating inside the feed

• A strong musty or sour smell

• Severe insect infestation

• Feed that simply doesn't look or smell right

When you are unsure about questionable feed, replacing a bag of feed is much less expensive than risking the health of your flock.

Bugs in the Aviary: When It's NOT a Feed Pest

Now we get into a completely different category.

If the bugs are crawling on your quail rather than primarily living in the feed, you may be dealing with an external parasite.

Two of the most important mites for poultry keepers to recognize are the northern fowl mite and the red poultry mite.

Northern Fowl Mites

Northern fowl mites are blood feeding poultry parasites.

Unlike grain mites, these mites spend essentially their entire life cycle on the bird.

Where should you look?

Start around the:

Vent → tail → breast → back → legs

The vent area is especially important.

Part the feathers and look closely at the skin and feather bases.

You may notice:

• Tiny dark moving specks

• Blackened or dirty-looking feathers

• Mite eggs around feather shafts

• Dried blood

• Scabs

• Irritated skin

Heavy infestations can cause:

• Reduced egg production

• Reduced feed intake

• Poor growth

• Irritation and stress

• Anemia

Northern fowl mites may also bite humans and cause itching or irritation.

Red Poultry Mites

Red poultry mites behave very differently.

Instead of living continuously on your quail, they typically hide in the aviary during the day and feed on birds at night.

That makes them easy to miss.

During daylight hours, inspect:

• Cracks

• Wood joints

• Cage connections

• Nesting or shelter areas

• Dark corners

• Under equipment

• Crevices around feeders and structures

The mites may appear gray, brown or reddish depending on whether they have recently fed.

Try a nighttime inspection.

Take a flashlight into the aviary after dark and examine both your birds and the areas immediately around where they rest.

A nighttime inspection may reveal mites that weren't obvious during the day.

Poultry Lice

Poultry lice are another external parasite that quail keepers should recognize.

Unlike mites that feed on blood, poultry lice generally feed on feathers, skin debris and material from the bird's skin.

Look for:

• Small insects moving through feathers

• Feather damage

• Eggs attached near the base of feathers

• Excessive scratching or preening

• Irritated birds

• Poor feather condition

Severe infestations can affect the overall condition and productivity of the flock.

Where Did the Mites or Lice Come From?

Even a well-maintained quail setup can develop external parasites.

Potential sources include:

Wild birds

Sparrows and other wild birds can carry external parasites.

This is one reason I don't want wild birds sharing feeders, waterers or housing areas with my quail.

Rodents

Rodents can contribute to parasite movement and create additional sanitation problems around feed storage and aviaries.

New birds

Any time new quail enter your property, you have the potential to introduce something you didn't previously have.

Equipment

Used cages, crates, feeders and other poultry equipment can potentially transport pests between flocks.

Good biosecurity matters even in a small backyard quail operation.

My Regular Quail Bug Inspection Routine

You don't need to wait until you have a major infestation.

Make bug inspection part of your regular flock-management routine.

Check the feed.

When opening a new bag, look at it before dumping it into your storage container.

Look for:

• Moving insects

• Fine powder

• Webbing

• Holes in whole grains

• Clumping

• Moisture

• Mold

• Strange odors

Check your birds.

Pick up several quail and inspect:

• Around the vent

• Under the wings

• Around the tail

• Breast feathers

• Feather shafts

• Legs and feet

Don't just look at one bird.

Parasite numbers can vary dramatically from bird to bird.

Check the aviary.

Pay special attention to:

• Cracks

• Corners

• Wood joints

• Areas underneath feeders

• Dark hiding places

• Spilled feed

• Damp bedding or waste

Then occasionally repeat the inspection after dark.

How I Prevent Bugs in Quail Feed

Prevention is much easier than trying to deal with a major infestation.

1. Don't overbuy feed.

Buying several months of feed because it is on sale may not actually save money if the feed deteriorates before you use it.

Buy quantities appropriate for your flock and rotate them regularly.

2. Keep feed dry.

Moisture is the enemy of stored feed.

Store feed in a dry location protected from rain and excessive humidity.

3. Use sealed storage containers.

A secure container helps protect feed from:

• Insects

• Rodents

• Wild birds

• Moisture

4. Rotate your feed.

Use the oldest feed first.

Think:

First In → First Out

Don't continually pour new feed on top of old feed and allow older material to accumulate at the bottom.

Empty and inspect the container periodically.

5. Clean spilled feed.

Feed underneath cages and feeders provides an ongoing food source for insects and rodents.

Keeping the aviary clean is part of pest prevention.

What About Diatomaceous Earth?

You will frequently see diatomaceous earth recommended online for poultry pests and feed storage.

Some poultry resources recommend food-grade diatomaceous earth for certain applications.

However, I take a more cautious approach around my quail.

Diatomaceous earth is a very fine dust, and inhaling airborne dust can irritate the respiratory system.

Quail are small birds living relatively close to the ground and bedding, so I don't want unnecessary dust circulating through their breathing zone.

Instead of depending on powders to compensate for questionable feed, my first line of defense is:

fresh feed + dry storage + sealed containers + sanitation + regular inspection.

For an active external-parasite infestation, identify the parasite first and use a treatment specifically labeled and appropriate for poultry, following the product label regarding application, safety precautions and any egg or meat withdrawal requirements.

Don't Confuse Grain Mites With Poultry Mites

This is probably the most important takeaway from this article.

Grain mites live in stored feed.

Poultry mites parasitize birds.

Finding tiny bugs in your feed does not automatically mean your quail have mites.

And finding mites on your quail isn't something you fix simply by throwing away the feed.

Correct identification tells you where the problem is coming from and what you need to address.

Final Thoughts From Shady Hollow Quail

Raising quail teaches you to pay attention to small changes.

Sometimes that means noticing that your birds aren't laying normally.

Sometimes it's a change in their feathers.

And sometimes it's opening the feed bin and thinking:

"Did that just move?"

Don't panic.

Figure out where the bug is living first.

Check the feed.

Check your quail.

Check the aviary.

Then identify what you're dealing with before reaching for a treatment.

Good feed storage, sanitation, biosecurity and regular flock inspections can prevent many small pest problems from turning into major ones.

At Shady Hollow Quail, our goal is to help new and experienced quail keepers understand not just what to do, but why we're doing it.

The more you understand your birds and their environment, the faster you'll notice when something isn't right.
