Tiny Black Bugs In House | Identification & Control

Having tiny black bugs in house can really be pesty, as bugs are one of the largest species of living things that exist on planet earth. Bugs are the most diverse group of animals as they include more than 1 million species, and make up more than half of all known living organisms.

What are tiny black bugs? are these tiny black bugs insects? lucky for you, this article has been well set up with adequate research to provide you with answers to these questions. Now let us bug our way into the mind-thrilling answers to this article!


What are Tiny Black Bugs in House?

A tiny black bug is a member of the class Insecta and belongs to the phylum Arthropoda, which itself is the largest of the animal phyla. Tiny black bugs have segmented bodies which are divided into:

  • The Head: Bears the eyes, the antenna, and the mouthpart.
  • The Thorax: Bears the legs and the wings as well.
  • The Abdomen: Bears the digestive, excretory, and reproductive organs.

These bugs have jointed legs and an exoskeleton, and are distinguished from other arthropods by their body segments.

Tiny black bugs are in many ways useful to man as they:

  • Help in the pollination of flowers
  • Can be used for research purposes
  • Serve as environmental indicators to assess water quality and soil contamination
  • Produce useful substances
  • Serve as a source of food
  • Help in the extermination of pests (Although they sometimes are the pests)

The tiny black bugs are among the successful group of animals as they have a high rate of distribution and adaptability.


What is the Anatomy of the Body of Tiny Black Bugs?

As stated earlier, tiny black bugs belong to the Phylum Arthropoda. Similar to other arthropods, they have an exoskeleton (a hard outer covering made of chitin that protects and gives the body support) with no interior skeleton.

It was stated earlier that the body of the tiny black bugs in the house is divided into 3 parts:

  • The Head
  • The Thorax
  • The Arthropod, etc

The head of a tiny black bug is known for bearing the compound eyes, antennae, the mouthpart for food intake, etc; The thorax serves as the grip point that bears the legs for locomotion and the wings as well; and the abdomen is used for digestion, reproduction, excretion, and respiration.

Below is a tabular description of the body segments of the tiny black bugs:

The Head The head of the tiny black bugs is housed in a hard exoskeleton, though this is exceptional in species whose larvae are not completely hardened. The head bears most of the sensory organs (antennae, simple eyes, and compound eyes) of the bug’s body and the mouthpart as well.

In the adult bug, the head is unsegmented, though research has shown that it consists of 6 segments, including the mouthpart.

Of all the bug orders, the Orthoptera (an order of bugs that comprises the grasshoppers, locusts) displays the greatest variety of attributes found in the heads of bugs.

Here,  the dorsal region is situated between the compound eyes of bugs with hypognathous (having the lower jaw longer than the upper) and opisthognathous (having backward-pointing jaws) heads.

However, In prognathous (having a projecting lower jaw) insects, the dorsal region is not found between the compound eyes, but rather, where the simple eyes are normally found.

The Thorax The thorax of a tiny black bug as mentioned earlier is said to bear the legs and the wings of the bugs. The bugs thorax is made up of three segments:

  • Prothorax
  • Mesothorax
  • Metathorax

The prothorax is the anterior segment closest to the head; its major features are the first pair of legs and the pronotum (the plate-like structure that covers the thorax). The middle segment is the mesothorax; its features are the second pair of legs and the forewings if they have one.

The third segment is the metathorax, which bears the third pair of legs and the hindwings. Each segment has four basic regions. The dorsal surface is called the notum, the two lateral regions are called the pleura, and the ventral aspect is called the sternum.

The notum of the prothorax is called the pronotum, the notum for the mesothorax is called the mesonotum and the notum for the metathorax is called the metanotum.

The Abdomen The abdomen (lower part) of an adult bug consists of 11 to 12 segments and is less sclerotized than the head or thorax. Each division of the abdomen is made up of the tergum and the sternum. The tergum is separated from one another and from the adjacent sternum by a membrane.

The variation of the lower part of the abdomen consists of the fusion of the tergum to form a continuous dorsal shield. During the embryonic stage of most insects, eleven abdominal divisions are present. There is a reduction in the number of abdominal segments in modern bugs though.


5 Tiny Black Bugs In House Exposed

After looking at a brief f explanation of what these tiny black bugs in house are, we will be explaining the 5 most common tiny black bugs that are more outstanding than the rest:

The Ants

The length of an ant may range from 0.0625 inches to 0.5 inches long.

As we all know, ants are one of the most common pests everywhere in the world as they can be found in every place except Antarctica. They will feed on grains, crumbs, and necessarily anything captioned food.

Ants have 6 legs just like every other insect and bodies with three segments (the abdomen, thorax, and head). They also have antennae which they use to smell food and detect movement.

Some ants stray from their companions to find their way inside your home while some only travel and form large colonies. When a reliable source of food is detected, they lead the rest of the colony to the food so that they can bring it back to the queen, who lives underneath the ground in an anthill.


The Weevils

Weevils are 0.125 inches long and have a rounded abdomen. The beans weevil ranges from 0.25 inches in length, while the rice weevil is slightly smaller at 0.1875 inches.

Weevils are beetles that belong to the superfamily Curculionoidea and are popularly known for their elongated snouts. There are about 98,000 species of weevils known, and these belong to several families, with most of them in the family Curculionidae.

The weevil is a common pantry pest that often enters the home and through food products like:

  • Grains,
  • Cereals,
  • Pasta
  • Pet food,
  • Basically any dry foodstuff.

They have hard and shiny shells with many little dot-like impressions and antennae that bend at the midpoint.

The Termite

Termites measure 0.25 inches in length, their large, detachable wings are not included, and the queen can grow over 4 inches long.

The termite is one of the most invasive indoor pests as it usually appears in homes during the springtime when they swarm and look for a place to start a new colony. They usually feed on wood and boreholes into the wood when they detect an enormous surplus of wood.

A termite colony consists of:

  • The queen
  • The workers
  • Reproducers
  • Soldiers

You will hardly see the queen come out of the colony as the workers, reproducers, and soldiers are the ones who work the most.

Reproducer termites have long, flat abdomens with a horizontal ribbing pattern and straight antennae, and resemble black ants whose wings usually fall off after finding a food source.

The PillBug

As adults, pillbugs can range between 8.5 millimeters and 18 millimeters in length. Many of the larger pill bugs seen are actually sowbugs, a slightly larger related species.

The Pillbug, also known as the woodlice, is a common pest that dwells in potted plants and damp areas of your home.

Pillbugs have dark gray or brown bodies that are often black unless viewed under a microscope. They have round, segmented shells that look like the armor of the armadillo.

They mostly live in indoor plants, and moist areas of the home, and so will feed on decaying plants.

The Flour Beetle

The flour beetle is a bit larger and longer than the weevils, as they measure 0.14 inches long as mature adults and look like tiny worms.

The flour beetle is a member of the genera Tenebrio. They are used as laboratory animals since they are easy to keep and will feed on:

  • Wheat
  • Flour
  • And other grains

Flour beetles are able to survive in dry environments and are capable of withstanding high radiation amounts than roaches.

Flour beetles have oval-shaped, narrow bodies with black, dark brown shells. They have wings and wing pads that have a vertical pattern.



Having the tiny black bugs In house can be very disturbing, as these pests are capable of causing mayhem and destruction to properties, and foodstuffs in the house.

  • Keep your house and yard as clean as possible to discourage insects from visiting
