Below, we look at some of the most common tiny brown bugs that thrive in the kitchen:

1. Flour Mites 

Also Called Grain Mites

Also called grain mites, flour mites are tiny, making them difficult to see. They are some of the most common pests in the kitchen or pantry. They infest a wide array of foods, including:

  • Corn
  • Cheese
  • Cereals
  • Dried fruits
  • Flour


The flour mite is a member of the Acaridae family. The length ranges from .33 to .66mm. Hence, they are often too tiny for the naked eye to detect. Nonetheless, you can spot their presence in food quickly when they infest in clusters. 


While many are brown, some can also range from white to gray. They have clawed legs with colors darker than their bodies.

How Do You Know If You Have Flour Mites in the Kitchen

One of the first indications of these tiny brown bugs on the kitchen counter is the presence of fine dust. When the dust moves, they are likely flour mites. You can put a flashlight on the area to have a clearer view of the supposed movement. 

Another thing that you can do is to take a pinch of flour in your fingers. Roll your fingers lightly and smell the flour. If it is minty, it can signify that there are flour mites. 

2. Weevils

Part of the Beetle Family

A part of the beetle family, weevils make up 40% of the world’s insects. They thrive in many places, including kitchens and pantries. They have long snouts, which is one thing that differentiates them from other beetles. 

Three Common Types of Weevils in the Kitchen

Three main types of weevils can show up in the kitchen: 

  • Rice weevil 
  • Wheat or granary weevil 
  • Maize weevil 

Hard to Detect

With the size of these tiny brown bugs, they are pretty difficult to detect. Hence, in most instances, it is too late before you can act to control the damage they have caused in the kitchen. 

Affects the Quality of Produce

Nonetheless, while these tiny brown bugs on the kitchen countertop, pantry, and other kitchen areas are pesky, they do not carry diseases. But this does not mean that they won’t be a problem. They will affect the quality of produce. 

Check the Food Before Buying

Weevils do not start indoors. Instead, they are from the outdoors. They can enter your home through contaminated food. Alternatively, they can also fly into the kitchen. Plus, they can lay their eggs on dry items. So, the food you brought possibly already had weevil before entering your household. 

How Do You Know If You Have Weevils in the Kitchen

One of the best ways to identify the presence of weevils in the kitchen is to look at rice or other grains. Females are known for using their mandibles to chew kernels when laying an egg. They can quickly destroy grains since many weevils will lay up to 400 eggs.

A small and flat insect with an average length of 1/12 inch, the foreign grain beetle, can range from brown to red.

Upon close inspection in a microscope, you will see that it has two peg-like projections at the back of the head. However, they are almost invisible to the naked eye, making their identification challenging. 

They can be confused with many other insects. For instance, some people might think they are fruit flies or gnats. However, foreign grain beetles are different because they have a hard outer shell. They can also be confused with lice and fleas, but these insects do not have wings.

Thrive in Damp Areas with Fungus

Foreign grain beetles thrive in damp areas with fungus, which are common in the kitchen. Their reproduction requires at least 65% humidity. They will also feed on moldy and damp products, which is why they are among the most famous tiny brown bugs in kitchen cupboards.

Easy to Eliminate

While they can reproduce in large numbers within a short time, the good news is that it is also quick to eliminate them. When the humidity falls below 60%, they will die and disappear, even without you doing anything else. 

Even if foreign grain beetles can be a nuisance, note that they are not harmful to humans since they do not bite. Additionally, they will not infest furniture.

Below are some of the most effective solutions to eliminate tiny brown bugs in the kitchen sink, cupboard, counter, or other areas. Many of these are also applicable if you seek solutions to remove mites in the kitchen:

1. Clean Your Kitchen 

The most effective solution for eliminating tiny brown bugs in the kitchen is to keep the area clean. Doing so will eliminate bugs and other pests that can be a headache in the kitchen, including ants. 

Bugs will thrive in dirty environments. So, the cleaner your kitchen is, the lesser the chance that the bugs will be a nuisance.

Keep the sink free of dirt and residual food particles after washing the dishes. Wipe the counter all the time. Pay attention to the garbage disposal and trash bin. Make sure to avoid the dark areas you often tend to ignore. 

The pantry is one more area that you should keep clean. Make it a routine to declutter, removing foods you are no longer using. The same thing is true with the kitchen drawers. 

2. Keep the Kitchen Dry 

Aside from dirt, moisture is another common problem in the kitchen. It increases the humidity, making it another culprit for the proliferation of tiny brown bugs.

From steaming food to boiling water, many kitchen activities contribute to moisture. Even external conditions can make the kitchen moist. 

Among others, one of the most effective ways to combat moisture in the kitchen is to ensure good airflow. This is possible by installing an exhaust, such as in the range hood.

Having enough air circulation can help counter bugs. You can also line shelves with paper, which will effectively absorb moisture. Another thing that can help is frequently wiping surfaces, especially those that often get wet. 

3. Store Your Stuff Properly 

Improper storage of food items in the kitchen and pantry is one thing you can blame for the appearance of brown and tiny white bugs. An easy solution is to ensure proper storage to limit the possibility of having pesky bugs. 

If possible, transfer items in a container instead of retaining them in their original packaging. Whether it is rice, flour, cereals, or other food items that can attract bugs, keeping them in a container with a closed lid will prevent the entry of bugs. Kitchen pests can easily infiltrate papers and plastics. 

4. Consider Natural Solutions 

Do not use chemicals if you want to eliminate tiny brown bugs in the kitchen. Instead, below are some of the most promising natural and non-toxic solutions: 

  • Use one-part vinegar and one-part water when cleaning the pantry or kitchen. Vinegar has natural properties that will act as a repellent, preventing the bugs from returning. 
  • Putting bay leaves in the pantry can also work. Aside from bugs, they can also deter other pantry insects, such as cockroaches, moths, ants, and flies. 
  • Create a homemade bug spray. Mix essential oil like lemongrass, peppermint, citrus, citronella, tea tree, and catnip with water. Spray them regularly in the kitchen, but make sure that you do not apply them directly to food items.
