Yearlong sunshine and high humidity make life easy for bugs for many bugs and pests in Florida homes.
This guide will reveal ten tiny black bugs in Florida that are common in the homes of the sunshine state.
You’ll learn to identify these bugs like a pro, find out where they hide in your Florida home, and the quick hacks to eliminate them.
Let’s get into these little black pesky pests.
Biting midges are the tiny black biting gnats that are widespread biting bugs in Florida, especially in coastal areas of South Florida.
Biting midges, also known as punkies, bite humans to feed on their blood.
Midges grow up to 1-3 mm in size. They’re gray and they turn reddish after the bloodmeals.
Their wings are transparent with dark patterns.
When at rest, the wings cover their entire bodies giving them a stocky grayish appearance.
Biting midges are also known as no-see-ums because they’re hard to see.
So, when they bite you, you can’t figure out what’s biting you.
Their sharp blade-like mouthparts rip open the skin to draw the blood. That make their bites very painful.
Red welts and intense itching ensue after the bite that can last for days. But midges’ bites don’t cause any diseases.
Biting midges bite many outdoor enthusiasts in the summer when they camp near water bodies.
Bites occur mostly during the dawn and dusk.
However, these biting flies can also be present in the residences, especially when there’s a habitat in the property that supports them.
Biting midges multiply on the same habitat where mosquitoes do.
Adult biting midges lay their eggs on the damp soils, stagnant water, and decaying organic matter near water bodies.
So, if you’ve got a lush green garden or yard with a swimming pool in Florida, then you can have a biting midges infestation.
They’re also a big problem in barns and farms where there’s livestock, manure, leaf litter, decaying organic debris, and dense vegetation.
Glowing light bulbs can attract biting midges inside the house.
They can sneak inside the house through the windows to reach the light source.
To get rid of biting midges, it’s essential to destroy their habitat where they breed.
Removing decaying organic matter, keeping the outdoors clean, eliminating stagnant water, using insecticide sprays or diatomaceous earth on the wet soils kill adult midges and their larvae.
While outdoors, use a skin friendly DEET based repellant to keep these little biting flies away from you.
Fungus gnats are non-biting gnats that breed in the damp wastes and wet soil beds of potted plants and gardens.
These small black flies are common in Florida residences, especially when there’s a damp waste problem in the house.

That’s why you might notice little dead flies inside your refrigerator.
Glowing light bulbs also draw fungus gnats inside the house.
If there’s a gnats infestation at your outdoors, you’ll notice fungus gnats near windows trying to make their way inside.
But here’s the best part.
Getting rid of the fungus gnats is easy.
All you’ve to do is remove the wastes, clean the drains, and use repellants like peppermint essential to eliminate them.
Scattering natural gnats killers like diatomaceous earth on the soil beds, compost piles, and trash bins is a good alternative to insecticide sprays.
Keeping sticky traps near potted plants and in places where you’ve noticed fungus gnats activity also helps in removing them.
Florida has a big pantry pest problem. There are two pantry pests that infest kitchens in Florida homes are the rice weevils and flour beetles.
You’ll find out about the flour beetles in a minute.
But rice weevils sneak inside the kitchen by being present in grains bags that you purchase from the grocery store.

They use the snout to insert inside the grains to draw the nutrients.
Rice weevils are either black or reddish-brown. And they’re oblong shaped, growing up to 2-3.5 mm in size.
Rice weevils don’t contaminate the stored grains. They’ll lay eggs in the stored grains.
When the eggs hatch, the infestation gets bigger.
Moisture also draw the rice weevils.
So, you can also notice weevils in the bathroom if too many of them have multiplied inside the kitchen.
Too many rice weevils in the stored grains causes the grains to become stale. You can also notice a bit of stench from the infested grains too.
Thoroughly cleaning the kitchen, keeping repellants like bay leaves or cinnamon sticks on the pantry shelves, and storing food in air tight containers are the best way to keep weevils away.
You don’t need to throw away infested grains and cereals.
Either heat them or put them inside the freezer for a day to kill the weevils, their larvae, and their eggs.
Wash the grains to remove the dead weevils.
Flour beetles are common pantry pests in not only Florida, but across the States.
These beetles infest grains, flour of all types, and baked foods too.
Flour beetles enter homes by being present in the food packets that you buy from the stores.

Their numbers peak up abruptly when you ignore their presence in your kitchen.
And they become to easy spot in your entire home, especially near the windows and windowsills.
Flour beetles contaminate the stored food by feeding on it.
The dead adult flour beetles on the stored grains and flour, the fecal pellets, and cast skin cause a pungent and nauseating smell in the grains.
It’s better to throw away the grains and flour that flour beetles infested.
You can eliminate flour beetles by using the methods to get rid of rice weevils.
Prevention is better than the cure when it comes to dealing with pantry pests.
It’ll be best not to use any insecticide sprays in the kitchen pantry to eliminate these pests.

The Florida carpenter ants can bite in self defense. But they don’t actively seek humans to bite.
To build their nests, carpenter ants look for places inside the house that have moisture problems.
So, damp floors and walls, places where there’s a lot of water usage like bathroom, kitchen, and basement are the common places where they’ll build their colonies.
Damp window sills, doors, and decks are also easy targets for carpenter ants to nest.
Getting rid of carpenter ants can be a tricky affair because they build multiple nests inside the house.
Finding the nests and eliminating the queen ants in the nest are vital for removing carpenter ant infestation.
So, it’ll be best to hire a pest controller to control them.
Black Carpet Beetles
Black carpet beetles in Florida are menace to both stored food and natural fabrics.
These beetles are oval-shaped, 3-5 mm in size, and they’re able fliers.

The carpet beetle larva chew on the natural fibers and create threadbare holes on them.
They’ll also leave behind there fecal deposits and shed skin on the fabric.
Synthetic fibers are immune to carpet beetle larvae damage.
But synthetic fibers blended with natural fibers is vulnerable to carpet beetle larvae damage.
Carpet beetle larvae can crawl inside the closets and drawers and target the clothes made from natural fabrics.
Stained fabrics also attract them.
Therefore, dirty bed sheets with food stains or sullied clothes kept in the laundry bins also draw the attention of the larvae.
