Let’s dive in.

Carpet Beetle Larvae

Carpet Beetle Larvae

The most common slow-moving tiny black bugs in the house are the carpet beetle larvae.

The carpet beetle larvae hatch out of the eggs that adult carpet beetles lay in your home.

Adult beetles fly or crawl inside the house, especially during the spring, to lay eggs.

They’ll lay eggs on things like carpets, rugs, couches, and clothing made from natural fibers like wool, silk, leather, fur, and feather.

They do it because the protein present in the natural fibers is the food source of carpet beetle larva.

The carpet beetle larvae feed on natural fibers which causes the damage.

The damages are in the form threadbare holes.

The larvae also leave behind shed skins and fecal deposits which are the signs of their presence.

The adult carpet beetles can also target stored food in your kitchen pantry.

If you don’t close the airtight containers properly, or if there’s a fissure on them, then the adult beetles will sneak inside the containers to lay their eggs.

Stored pet food is also vulnerable to carpet beetle infestation.

On top of being a damaging fabric pests, the carpet beetle larvae are also grain insects like the flour beetles and rice weevils.

A carpet beetle larva is of ¼ – 1/8 inch in size. It’s black or dark brown with hairy bristles on its body.

The body has five segments and there are also small invisible legs that it use to crawl slowly.

Some larvae can also have yellowish or brownish patches on their bodies.

The larvae don’t bite. But the hairy bristles on their bodies can cause serious itching if they crawl onto your skin.

The adult carpet beetles are harmless. Outdoors, the adult carpet beetles feed on nectar and pollen.

There are three primary types of carpet beetles that invade homes – the black carpet beetle, varied carpet beetle, and the furniture carpet beetle.

The furniture carpet beetle can also lay it’s eggs in the gaps on upholstered furniture.

It’s not only the natural fibers and stored food the adult carpet beetles target to lay their eggs.

Carpet beetles can also lay their eggs on wall voids, and in places like attic, especially when there are dead insects in them.

It’s because the dead insects are also a food source for the larvae.

Upon feeding, the larvae will venture out of the wall voids to look for dead insects and spider webs to eat.

That’s why you can notice them crawling on the walls and ceiling too.

Bed Bugs On Bed

Worried I brought bed bugs home

Bed bugs aren’t typically black. They can appear as black because of their dark reddish-brown color.

And on the bed, bed bugs are slow crawlers.

The ones that had their bloodmeals will move slowly because their bellies are full of human blood.

Bed bugs are parasites that bite humans to feed on their blood.

And their bites are intensely itchy. Red welts and itchy rashes develop on the skin after the bites.

But some people don’t show any symptoms when bed bugs bite them.

Outdoors, the pill bugs feed on the decaying organic matter like leaf litter, rotting wood pieces, and on the molds and fungi on the soil beds.

They’ll hide underneath rocks and potted plants.

Pill bugs are moisture bugs. They prefer wet and damp places to live.

So, when the weather outdoors becomes too dry, pill bugs move inside the house looking for damp places.

The best part is that pill bugs are harmless. And they can’t lay eggs inside human homes.

So, there’s no chance of infestation.

Clover mites enter homes when the weather outdoors becomes too hot or cold.

They’ll gather on window sills and window frames looking for entry points to sneak inside your home.

Clover mites are dark red. But they can appear as tiny black bugs at the first look.

Clover mites are extremely tiny. They grow only up to 1/30 inch long.

The segmented abdomen is visible when they crawl on the soil beds or rotting debris.

The adult roach beetles are strong fliers and can cover considerable distances.

Like the predaceous devil’s coach horse beetles, the roach beetles raise their abdomen upwards if you poke or disturb them.

Rove beetles move slowly. These insects eat any tiny bugs or larvae that move slower than them.

Rove beetles look like earwigs and they seldom enter homes.

But they can sneak inside human homes looking for debris and leaf litter.

Rove beetles are nocturnal bugs. At the outdoors they’ll hide underneath rocks, wood pieces, and plant pots.
