On our previous post on microscopic bugs that bite, we revealed biting bugs that are quite impossible to see by naked eye.

That list contained minute biting bugs like chiggers and biting mites like rat mites and bird mites.

However, the 9 tiny black bugs that bite are NOT invisible or microscopic. You can easily spot them.

But given their sneaky nature and their unique ways of biting, these bugs can be hard to deal with. But we’ve got your back.

Let’s get into each of these little black bugs that bite and find out why, when, how, and where do they bite.

Later in the post you’ll find out the easiest-to-implement ways to deal with them.

Pirate BugsThe Tiny Black Outdoor Bug That Bite

Black Microscopic Bugs That Bite Pirate Bugs

Pirate bugs are outdoor bugs, and they’re most likely to bite when you’re engaged in any outdoor activity.

They fly in swarms, so many people confuse them with mosquitoes. But they’re so tiny that they look like black dots, if you can see them.

Pirate bugs are active during the summer months, and outdoors, you’ll find them near moist and damp areas.

Pirate bugs bite repeatedly. But they don’t inject anything inside you, nor do they carry any diseases. 

They’re looking for a new place to hide and sources of food, and when they land on you, they think that you may be that. 

Pirate bugs have a sharp beak-like mouth that they insert into your skin to probe on what they’ve landed on. Their bites are pretty painful, and you’ll get welts and red rashes on the bitten area. 

Insidious Flower Bugs

Insidious flower bugs, twice as big as the period at the end of this sentence, is also an outdoor bug that bites humans. 

Why they bite humans is still unknown. But the best part is that, like pirate bugs, insidious flower bugs don’t inject anything, nor do they transmit any diseases.

When insidious flower bugs bite you, the only thing they leave behind is bite marks. These bite marks are red welts and rashes that are very similar to mosquito bite marks.

Studies have shown that they tend to bite people when they’re sweating.

And they also have a habit of entering your home through open doors and windows.

Insidious flower bugs are active during late afternoons, starting from the summer to autumn. 

Female Gnats – The Tiny Black Flying Bug That Bite And Causes Itching

Fungus gnats - tiny black bugs in houses near windows

Gnats are mosquito look-alikes that live and breed outdoors. These are delicate tiny black flying bugs that bite.

Places like moist soil beds in your yard or garden and pots, compost, potting-mix, and decaying organic debris like foliage and mulch beds are their living and breeding places.

Gnats can enter your home too. And they do, especially when the outdoors becomes too dry and hot for them.

Dry weather will cause the wet debris and soil beds to dry up. That forces the gnats to enter your home in search for cooler and mild places to live.

Once inside your home, gnats will look for damp and cool places to hide. That’s why they end up in places like bathroom and in electrical appliances like refrigerator.

Another reason that brings gnats home is that they’re attracted to light.

Light coming out of your home in the evening hours attracts the gnats.

That’s the reason why gnats can also land up in the swimming pool. It’s because the light around the swimming pool attracts them.

Bringing potted plants home, with gnats in the soil bed of the pot, is also another way to bring gnats inside your home.

Despite being a mosquito look-alike, how would you distinguish between a gnat and mosquito?

The most critical difference between the gnats and mosquitoes is that the gnats are very weak fliers.

They can’t fly as strongly as mosquitoes do. To go from one place to another, gnats tend to hop more than they’ll fly.

Outdoors, gnats will feed on the nectar and pollen of flowers.

However, there’s an important point to note. The male gnats don’t bite.

It’s the female gnats that bite humans, livestock, poultry, and even pets. Without blood meals, female fungus gnats can’t breed and lay eggs

The bite from female gnats is severely itchy, or as itchy as mosquito bites.

Female gnats will use their sharp mouth parts to rupture the skin and access the veins to suck the blood.

So, if gnats are inside your home, these tiny black flying bugs will indeed bite you.

No-See-Ums – Small Black Biting Flying Bug

Tiny black flying bug that bite and itch - No See Ums

Another black flying and biting bugs are the no-see-ums. They’re also known as biting midges.

No-see-ums are minute and they’re not that easily visible.

Biting midges are outdoor biting flying bugs. These bugs are a menace for hikers, campers, and trekkers.

Biting midges are so tiny that it makes you wonder that what’s biting you but you can’t see. Measuring up to only 1/8th of an inch, these bugs are greyish-black with white spots of pigmentation on their skin.

No-see-ums or biting midges are common in homes that are near the woods. They’re not that widespread in towns and urban areas.

Like the gnats, no-see-ums too are attracted to light. Inside your home they won’t shy away from biting you.

In the US, no-see-ums don’t cause any severe skin infection or dermatitis. But their bites are pretty itch and cause red rashes on your skin.

Fleas – The Tiny Black Biting Bug That Can Be In Your Bed!

Now fleas are the bugs that bite humans only when their natural hosts, which are your pets and other mammals, are not around.

Fleas are tiny biting bugs that get inside your home in one of the three ways.

The first is that your pet brings them home. Yes, if your pets have fleas, then those fleas can easily jump off to your bed or couch.

This is quite common when your pets spend a considerable time on your bed or couch. And this is how fleas get into your bed.

The second way that fleas get inside your home are through wild life like squirrels and racoons. They can transfer fleas to your home.

The third way is fleas latching onto your clothing when you’re outdoors.

Fleas hide and breed in tall grasses and dense bushes in moist areas. You walk through those grasses and bushes, fleas will latch onto your trousers and socks.

Fleas can live and hide in your bed. They’ll leave behind itchy bites on you while you’re asleep because they need their blood meals to survive.

On your bed fleas look black jumping bugs that bite. And they’ll leave behind flea dirt, which is their feces, on your bed.


California Bugs That Bite - Tiger Mosquito
Asian Tiger Mosquito

Mosquitoes are the most common tiny black flying bugs that bite. 

Over the years, because of overpopulation and increasing waste, mosquito infestations in homes have increased. 

There are no serious mosquito-borne diseases in the US. But some mosquitoes, like the Asian Tiger mosquitoes capable of spreading deadly diseases, are now active in the US.

Some of the diseases that these mosquitoes spread are Encephalitis, West Nile Virus, and dengue fever.

Mosquitoes breed on stagnant water. That’s why you must not allow water to accumulate in your yard or garden. 

If there’s a swimming pool in your yard, it can also be the source of mosquitoes. Mosquitoes are one out of many bugs in the swimming pool that can breed and increase in numbers if you don’t get rid of them.

Also, drains in the mosquitoes are a common occurrence, especially when you’ve got clogged drains in your home and catch basins in your yard.

Clogged drains are the reason for several bugs, including drain flies and drain roaches.

To get rid of mosquitoes in your home, use mosquito repellent sprays during dusk and dawn, as these are the times when they’re most active and more likely to bite you.

Mosquito bites are solitary itchy red welts or lumps. They never bite in clusters. 

As a long-term solution to mosquitoes, do not allow stagnant water, damp and organic wastes to accumulate on your property. 

Maintain cleanliness in your outdoors as much as indoors.

Black Carpenter Bees

Black carpenter bees are not aggressive unless they feel threatened. 

Unlike other tiny black bugs on the list, these bees won’t try to latch onto you to bite you or to feed on your blood.

The point to note here is that only the female carpenter bees bite. And that’s only when you try to handle them or when you go near their nests.

Female carpenter bees have stingers that they insert into your skin. That sting is painful and causes swollen redness on the bitten area. 

The male carpenter bees don’t have stingers, so they can’t sting.

Carpenter bees aren’t typically tiny. They’re half an inch long, and they’re thicker than house flies too. Carpenter bees are pitch black, but they’ve got distinctive yellow markings on their abdomen.

Carpenter bees are active from the early spring till late summer. At this period, they’ll look for wooden structures to bore and lay eggs.

The holes that they bore on the wood are a round-shaped and one-half inch in diameter.

The best way to protect yourself from these bees is not to go near their nests and refrain from poking them.

Leave the process of getting rid of carpenter bees to a professional. We don’t recommend handling these bees as removing them requires the removal of their nests. 

And while doing it, these bees will get aggressive, which will make them bite you. Pest control professionals know how to get rid of them with appropriate safety measures. 

Black Widow Spiders

Black widow spider infestation signs

When it comes to biting spiders, black widows are the most common. 

However, black widow spiders are not bugs. These are arachnids. 

Growing only up to 1/4th of an inch, these spiders sneak inside your home when the weather outdoors is too extreme for them.

It means if it’s too hot, too cold, or too wet outdoors, black widow spiders will look for drier and good places to live.

Inside your home, they’ll hide in tight gaps in places where you don’t frequent often.

So, places like the attic, basement, cracks, and fissures on the floor, walls and ceiling are some of the places where they hide.

Black widow spiders aren’t aggressive. However, if you’re a novice in getting rid of spiders, then they can bite you if you use the wrong ways to get rid of them. 

The signs of the black widow spider infestation are pretty evident in the places where they hide. 

If you observe those signs, it’s always safer to lure the spider out of hiding and trap them rather than going out all in the offensive. Leave it on the pest controller to do it.

Black widow spider bites are singular bites with two red dots, which are the fang marks. The bite wound looks like a swollen red lump, and it’s painful. 

But unlike the brown recluse spider bite, black widow spider bite doesn’t cause necrosis on the skin. 


Like spiders, ticks are also arachnids. They look like sesame seeds with visible legs. 

A fully developed adult tick grows up to only 1/8th of an inch. The tick larvae are even tinier, growing up to only 1/32th of an inch.

Ticks come in three different colors – reddish-brown, brown, and black.

Ticks are primarily parasites on animals from whom they have their blood meals. 

But, ticks can also bite humans, especially when they’re on the lookout for an alternative source of blood meals.

Like fleas, ticks also live in tall grasses and dense bushes in damp areas.

Ticks are hard to spot when they’re not biting you. But while they’re at your skin and drawing blood, that’s the time when you can notice them.

Ticks partially burrow themselves in your skin, reach the blood vessels, bite, and suck out blood. While they’re having their blood meals, you’ll notice that the frontal part is inside the skin while the back is visible.

Tiny black bugs that bite and itch - ticks

When they’re fully fed, ticks will turn bluish-grey. That state of fully fed tick is known as an engorged tick.

Most ticks don’t spread diseases, but some ticks do. The most common diseases that ticks spread are Lyme disease and rocky mountain fever.

The tiny black tick with black legs, also known as Ixodes tick, is the one that spreads Lyme disease.

If you notice a tick on your skin, remove it asap. If it’s half-burrowed into your skin, which means it’s feeding, use a tweezer to pull it out.

While pulling it out, the tick may leave its mouthparts behind, which can cause infection. So, it’s always a wise decision to see a doctor after a tick bite.

But don’t stop there. Remove all your clothes and ask anyone to check for ticks on your back. 

Please do not wear the same clothes again without washing them in warm water. There might be ticks latching onto your clothing that can bite you more if you don’t wash them.

Dealing With The Bites From These Tiny Black Bugs

Most of the bug bites from the tiny black bugs on the list are indeed itchy, cause red lumps, welts, and some bites are painful. 

However, it’s easy to soothe the pain and itches from these bites.

Essential oils like peppermint, antiseptic creams, and ointments are available to alleviate the itches and pain from these bites.

Washing the bitten wound with warm water then applying these ointments works even better. 

If there’s a burning sensation on the bitten wound, applying ice packs also helps.

But there’s a catch. 

Some people are sensitive to bug bites. They can show allergic symptoms like nausea, diarrhea, vomiting, and dizziness when bugs bite them.

In that case, it’s always the right option to see the doctor.

If a tick bites you, then you shouldn’t take a risk even if you’re not showing any of these signs. See the doctor as soon as you can.

Bites from ticks are unpredictable, and you never know what type of ticks bit you. It can be a tick that spreads Lyme disease. 

How To Get Rid Of Tiny Black Bugs That Bite?

Maintaining cleanliness and denying these bugs an entry into your home are two ways to get rid of these tiny black bugs.

However, there are other specific measures that you can tick to get rid of them. 

Seal Cracks And Crevices To Deny Them Hiding Places

The tiny bugs that bite most commonly hide in the tight gaps in and around your furniture, bed, floor, and walls.

Sealing them is the best way to stop them from hiding and taking refuge inside your home. 

Ensure that you seal all the cracks on your home’s walls facing the yard, window frames, and doors.

Trim Any Overgrown Bushes And Shrubs Bordering Your Home’s Walls

Most bugs exploit the overgrown bushes and shrubs as a bridge to get inside your home. 

And these bugs also include invasive and home-damaging pests like roaches, ants, and termites.

Trimming them or removing them from your home’s perimeter goes a long way to stop these bugs from entering your home. 

Use Window Shields With Fine Mesh 

Many of these bugs, especially no-see-ums and gnats, are attracted to light. 

They can fly inside your home through the open windows. 

Installing window shields with fine meshes stops these bugs from doing so. 

You don’t need to install window shields in all of your windows. Install them on the windows that are close to your patio and facing the yard. 

Use bug-repellent lights outdoors so that bugs and flying moths don’t get drawn to your home.

Reduce The Clutter Inside Your Home

Reducing clutter is an essential process to get rid of bugs, especially spiders. 

Get rid of stuff that you don’t need from your attic, basement, and storage rooms.

You don’t visit these places often, which creates an ideal hiding place for black widow spiders, and the worst, rats.

Ensure That Your Pet Don’t Have Fleas And Ticks

Believe it or not, your pet is one of the sources of fleas and ticks inside your home.

If your pet has them, it’ll transfer them to your home, and even worse, to your bed and couch.

In the absence of their primary hosts, both fleas and ticks are bound to bite you. 

So, ensure that your pet doesn’t have either fleas or ticks. 

Reduce Dampness In Your Yard

Water leakages in the yard and garden cause the dampness in the yard to increase. That attracts bugs of all sorts. 

Also, piling organic wastes like rotting leaves and woods, moist mulch beds, and stagnant water in potholes are the reasons for biting bugs like gnats and mosquitoes to breed. 

So, don’t overwater your yard, and do not let water accumulate in your yard after the rains.

Also, ensure that the drainage systems are working fine and they’re dispensing the wastewater properly. 

Clogged drains are also one of the reasons for mosquitoes, roaches, and drain flies.

Spray Insecticides Both Inside And Outside Your Home

There are many organic plant-safe insecticides available that you can use to get rid of these tiny bugs that bite from your home and property. 

Always read the safety instructions on the label before using them.

If you want to go all-natural, mixing white vinegar with warm water and using it as a spray also works.

Peppermint oil spray is also an excellent repellent for these bugs that you can use to get rid of them. 

Always Protect Yourself From Bugs While Outdoors

Many of these bugs will bite while you’re outdoors. Taking appropriate protection is vital to prevent these bugs from biting you.

Wear bug-repellent creams on your skin. Also, wear appropriate clothing that hides your lower body portion, including your knees and ankles. 

These are the common places where ticks and fleas can bite you. 

One more important thing to keep in mind – do not keep your luggage and clothes on the bed or couch after returning from outdoors. 

It’s because there might be bugs latching onto your clothing and luggage. You may transfer them on your soft furnishings if you take them straight inside your home. 

It’s always a good idea to spray a bug spray on your luggage and keep the luggage outside your home for a couple of hours before taking them inside your home. 

This is important, especially when you’re back from an activity like camping or hiking.

Also, put the clothes you’re wearing straight into the washing machine rather than putting them in the closet or throwing them in the bin bag.
