Tiny Black Bugs on Bed Sheets | Identification, Habitat, and Control

Black Carpet Beetle

The black carpet beetle is a common tiny black bug you can find around the house – especially if you have a carpet. These bugs munch on a variety of fabrics, including wool and silk. That’s why they can also infest bed sheets. 

Unfortunately, these beetles lay around 50 to 100 eggs. That can easily lead to an infestation once they hatch. Thus, it’s best to stop its spread before the eggs hatch.

  • Appearance: Black carpet beetles are small insects with oval-shaped bodies. Its color is either black or dark brown, with its outer shell looking shiny. It has three pairs of legs and a pair of long antennae.
  • Size: 1/8 to 3/16 inches
  • Scientific Name: Attagenus unicolor
  • Lifespan: 4 to 8 weeks
  • Habitat: Soil, under rocks, logs, and leaves
  • Diet: Leather, wool, silk, feathers, hair, dried meat, dead insects, and dried plant
  • Threat: Black carpet beetles do not bite. However, they love munching on carpets and other similar fabrics. This can create quite an eyesore – or cause welts on your sheets which can lead to discomfort.
  • Control: Prevention is always better than cure. To avoid a black carpet beetle infestation, make sure to regularly clean your bed sheets to prevent them from making a nest there. It also helps to have your sheets steamed to get rid of any eggs.

Wood Ticks

Wood ticks, also known as the American dog tick, are the common parasite that you can find on warm-blooded household pets. They have eight legs, which means that they are arthropods, although they are often misidentified as insects.

  • Appearance: Wood ticks are characterized by their flat, oval-shaped bodies that appear dark red or reddish brown. However, a female wood tick turns gray or green-gray when it is engorged with blood and ready to mate. 
  • Size: 3/16 inches
  • Scientific Name: Dermacentor andersoni
  • Lifespan: 3 to 5 months
  • Habitat: Woodland paths, parks, pastures, and backyards
  • Diet: The blood of mammals, birds, and reptiles
  • Threat: By itself, a wood tick doesn’t always bite humans. But when they do, their bites are often harmless, although these can be itchy. However, wood ticks can be carriers of certain bacterial diseases like the Rocky Mountain Spotted Fever or Lyme disease. 

However, the same may not be the case for your furry friends. Wood ticks often host warm-blooded animals like cats and dogs, and an infestation could lead to anemia and even paralysis. This is in addition to other bacterial infections or diseases that a carrier wood tick can transfer to your pet. 

  • Control: Wood ticks may get to your bed sheets whenever you allow a host pet to take a nap on your bed. The very first step you have to do to prevent it is by making sure that your pet doesn’t have any wood ticks. You can use anti-tick soaps, shampoo, and powder to keep these tiny arthropods away from your furry friend.

Swallow Bug

Swallow Bug

Swallow bugs, also known as American swallow bugs or cliff swallow bugs, are blood-feeding insects. It is so named because it commonly hosts swallows and other wild birds. These bugs are often mistaken for bed bugs, but they are often smaller and with a more grayish appearance.

  • Size: 3/16 inches
  • Scientific Name: Oeciacus vicarius
  • Lifespan: 2 to 3 years
  • Habitat: Grassland, marshes, marshes, and any similar areas where you can find cliff swallow nests

Spider Beetle

Spider Beetle

The spider beetle is a flightless scavenger insect that feeds on plant-based food products such as grains, almonds, and wheat. They are commonly found in pantries where food is usually stored. 

  • Appearance: The spider beetle looks like a tiny spider with a plump oval-shaped body. They are so named because they have three pairs of legs and two long antennae that look like legs – and that gives them the appearance of having eight legs. They are usually reddish-brown or dark red.

If you love snacking in bed, make sure to clean and vacuum your bed sheets to prevent spider beetles from being attracted to the crumbs and leftovers.



The batbug is another tiny black bug that’s commonly found on bed sheets. Otherwise spelled as bat bugs, these parasitic insects prefer feeding on the blood of mammals. It prefers the blood of bats and would often be found where bats often nest. However, it has made its way into urban areas where bats have grown accustomed – such as in old buildings or parks.

  • Lifespan: 9 months
  • Habitat: Mattresses, box springs, bed frames, and furniture

  • Control: Bat bugs do not normally enter a person’s home unless you have been to a place where bats live. In that case, it may have adhered to your clothes, shoes, or bags. In this case, don’t go straight to your room as soon as you get home. Make sure all your things are thoroughly cleaned to make sure that you have not brought any bat bugs into your home. 

In case you already have an infestation at home, experts advise using an aerosol bomb or an insecticide treatment to eliminate bat bugs once and for all. With them dead, make sure to clean your home thoroughly, especially paying attention to cracks and crevices where they may be hiding. 



Fleas are another small parasitic tiny black bug that you can commonly find on your bed sheets – especially if you have pets. These wingless insects often feed on the blood of their host animal but may also bite humans if no other host is nearby.

Unfortunately, a single flea can lay up to 50 eggs per day which last for around 50 days. And these eggs can fall off your pet when it shakes or scratches. That’s how it can easily lead to an infestation on your bed. 

  • Appearance: Fleas have oval-shaped yet plump bodies. They often appear reddish brown or dark brown. A notable feature is its long legs and rounded heavy bottom. 
  • Size: 1/8 inch
  • Scientific Name: Siphonaptera
  • Lifespan: 2 or 3 months

  • Diet: Blood from humans and pets
  • Threat: Aside from its quick reproduction that could easily lead to an infestation, fleas can be carriers of diseases. This is in addition to their painful and itchy bites – some of which can trigger severe allergic reactions. 
  • Control: To make sure that you don’t get a flea infestation at home, it’s best to always bathe your pet with anti-flea soap, shampoo, or powder. This is especially done after your pet has been out for a walk or has been to the dog park. This is to ensure that no flea is to enter your home and start a dreaded infestation.

Cockroach Nymphs

Cockroach Nymphs

Cockroach nymphs are the newly-hatched baby cockroaches. These are the tiny wingless versions of the adult cockroach. But while they are flightless, they can similarly spread diseases like their adult versions.

  • Control: In case of an infestation, you can diffuse citrus oils in your bedroom since cockroaches are known to be repulsed by that scent. To prevent the recurrence of an infestation, make sure your room – especially your bed sheets – is always clean. If you love snacking in bed, always vacuum right after eating to get rid of any leftovers that can further attract cockroach nymphs. It also helps to clean the entire house to make sure no cockroach nymphs or eggs remain hidden. 

Book Louse Bug

Book Louse Bug

The book louse bug is one of the hardest tiny bugs to spot because of its pale-colored body. Otherwise known as booklice, the book lousebug is known to munch on paper products, including the glue that binds books together. They’re primarily drawn to moist and moldy areas.

To get rid of them, you have to dispose of the affected materials, get rid of molds, and address the source of the leaks. And to prevent its recurrence, it’s best to invest in a dehumidifier to prevent the growth of molds.
