Outdoor activities can be fun, but it won’t be anymore if you encounter little black bugs that bite. They’re nasty pests that can ruin your day anytime.
What are these little black bugs? Black bugs are tiny, barely noticeable pests with a big bite, leaving small red bumps and a crawling sensation on your skin. They’re parasitic and feed on warm-blooded animals and humans. Some of the most common black bugs are the following: Bird mites, chiggers, fleas, gnats, insidious flower bugs, minute pirate bugs, and no-see-ums.
In the United States alone, several small black bugs bite people and pets. They’re usually attracted to your garden and yard due to the soil that contains organic materials, such as compost, wood chips, and more.
In this article, we’ll go through the most common black bugs that bite, including their scientific name, lifespan, diet, and habitat. This article also discusses the symptoms of their bites and how to get rid of them.
What Are the Common Black Bugs That Bite?
Bird mites are parasitic pests that can grow about 1/32 of an inch in length. They have a sharp mouthpiece used for penetrating their host’s skin to feed their blood.
You can identify them apart from other common black bugs by the following physical characteristics:
- Flattened oval body covered in short hairs
- Brownish or greyish in color but can appear darker after feeding
- Eight legs and two main body parts
This type of black bug is parasitic to poultry and birds. They live on wild and domestic birds, such as the following:
These mites live on birds or bird’s nests their whole life, but if the bird dies or the nest they live on is abandoned, they’ll look for other hosts. They can intrude into homes and bite humans, but they can’t reproduce on human blood.
Chiggers are microscopic larvae that are part of the arachnid family. They’re also called red bugs and typically live in tall grasses, weeds, berry patches, and wooded areas.
Chigger mites are tiny, so they generally look like small black bugs. Although they are tiny, their bite gives a powerful punch that you can surely feel. They’re most active during spring, summer, and fall when temperatures are mild and welcoming.
Chiggers have distinct features that can help you identify them apart from others, and these are the following:
- Red in color
- About 1/150 of an inch
Although these mites are almost impossible to see with the naked eye, you might be able to notice them when they cluster together due to their red color. Their red color, however, will turn into a yellowish color once they feed on human skin.
Fleas are external parasites common to dogs, cats, and humans. Their bites can cause intense irritation that a hypersensitive animal will need veterinary assistance after being bitten.
These pests are known to transmit tapeworms and bacterial infections. They can quickly jump into passing pets like dogs or cats and stick to human pants when given the opportunity.
These black bug species are highly productive—some of them could be living on one of your pets, in addition to hundreds of eggs that could hatch anytime in your home or yard. If infestations signs are ignored, they can multiply quickly and can be out of control.
When it comes to identification, you can identify them based on the following features:
- Flattened spines
- Rigid cuticle with many bristles
- Small and wingless
- Length varies from 0.039 to 0.13 inch
They’re known to feed on birds, the blood of mammals, including humans.
Gnats are tiny flying insects, categorized in the following:
- Fungus gnats: Have dark, long legs
- Drain flies: Have moth-like wings
- Fruit flies: Round and brown in color
They’re not known to be harmful to humans, but they can be to your plants. You can identify them apart from other mite species with the following characteristics:
- Slender flies
- Long legs
- Long antennae
Insidious Flower Bug
Insidious flower bugs are tiny yet effective predators of thrips, which are also pests. Apart from thrips, they also feed on:
- Insect eggs
If given the opportunity, they may also prey on other smaller animals and occasionally feed on plants. They have needle-like sharp beaks that inject digestive enzymes and suck up the slightly digested insides of their victim.
Minute Pirate Bugs
Minute pirate bug is another term for flower bugs. They lay eggs within the plant tissue, then nymphs surface after four to five days and become adults in seven to ten days.
These bugs are beneficial in managing harmful pests like thrips that are known to infest plants. Thus, it would be helpful to leave habitat for them to kill harmful pests in your environment.
No-see-ums are incredibly tiny flying insects that are difficult to spot. They’re also called punkies, biting gnats or sand flies.
These pests can be hard to detect due to their minuscule sizes that can fit through the screens on your doors or windows. You’ll only know about their presence when they start to bite you.
Apart from their painful and itchy bites, they’re also known to transmit diseases to humans.

What Causes Reactions to Bites and Stings?
The venom injected into your body causes the reactions to bites and stings as your body produces antibodies. Your body will likely get an immediate response, which includes swelling and redness at the bite site.
What Are the Symptoms of a Bad Reaction to Bites and Stings?
- A warm feeling on the site of the bite or sting
- Numbness or tingling in the bitten area
- Pain in the affected area

Step 2: Heat the ingredients using your stove and stir until it forms a paste.
Step 3: Allow the mixture to cool before applying it to a piece of cardboard.
Step 4: Once done, place the trap on the floor, cardboard, and in areas where you believe these bugs exist.
Use Essential Oils
1. Orange oil – Most insects, particularly bugs, hate citrus. Thus, it’s a good option in deterring black bugs from your premises.
2. Peppermint oil – The strong scent of this oil causes the black bugs to stay away from your place. So, it would be a good idea to spray this regularly on the affected area.
