Finding tiny black worms or bugs crawling around your house can be unsettling While many small black bugs are harmless, seeing them scurrying across floors and countertops is never a pleasant experience If you’ve noticed tiny black worm-like pests in your home, don’t panic—there are several effective methods for getting rid of them and preventing future infestations.
In this comprehensive guide, we’ll cover everything you need to know about identifying, removing, and preventing tiny black worms and bugs from invading your house.
What Are These Tiny Black Bugs?
Small black worms or bugs that show up in homes can belong to a few common pest species
-
Drain flies Also known as moth flies, drain flies are small, fuzzy, moth-like bugs about 1-5 mm long. They are often seen flying around sinks and tubs where they breed in drainage pipes, sewers, and very moist organic matter.
-
Fruit flies: These tiny flies about 2-3 mm long infest overripe fruit and vegetables. They breed rapidly in drains, garbage disposals, empty bottles and cans, trash bins, and floors where organic waste has built up.
-
Fungus gnats: These delicate dark flies with long legs are attracted to moist organic soil and decaying plant matter. They become a nuisance when they emerge indoors from overwatered houseplants and entryways.
-
Millipedes: While not insects, some small black millipedes with worm-like bodies invade homes seeking moisture and can leave behind an unpleasant odor.
Figuring out which of these pests you’re dealing with will help guide the best removal methods. Check areas around drains, pipes, plants, and trash to find their source.
Effective Ways To Remove and Kill Tiny Black Bugs
If you discover an infestation of small black worms or insects in your house, there are several effective DIY methods to get rid of them:
Use a vacuum cleaner
A simple way to remove and kill tiny black bugs is by vacuuming areas where you see them congregating. Use the hose attachment to thoroughly vacuum cracks, crevices, drains, crawl spaces, along baseboards, behind appliances, and under furniture where pests may be hiding.
Vacuuming picks up adult insects while removing eggs and larvae in debris. Immediately empty the vacuum contents into an outdoor trash bin after use.
Apply insecticidal spray
For quick control, apply an over-the-counter insecticidal spray labeled for indoor use, such as those containing pyrethrins. Spray insecticides directly on bugs to kill adults on contact. Also treat areas where they are emerging like drains, pipes, potted plants, and soil.
Be sure to read and follow all safety instructions when using insecticides. Avoid spraying onto food surfaces and utensils. Ventilate treated areas after use.
Use adhesive traps
Sticky glue traps and fly paper tape can help catch adult pests. Place traps along walls, under cabinets, and anywhere you’ve spotted the bugs. For flightless millipedes, put traps around floor perimeters. Check traps frequently and replace until infestations are under control.
Apply boric acid powder
Boric acid is an effective natural pesticide that can kill small insects through ingestion and contact. Lightly dust a fine layer in concealed areas like cracks, crevices, wall voids, under appliances, behind baseboards, and in other places bugs may hide. The fine powder sticks to their bodies, causing dehydration and death within days.
Pour boiling water down drains
If drain or fruit flies are emerging from drain pipes, pour a kettle full of boiling water directly into affected drains. This will instantly scald larvae and eggs lurking in the scum. Follow up by scrubbing the pipes with a drain brush. You can also use a bacterial foaming drain cleaner weekly to clear out organic buildup.
Clean up moisture and decaying matter
Eliminate breeding sites by keeping drains free of sludge buildup, drying out moist areas, removing trash promptly, and clearing decaying plant matter from pots and gardens. Fix any plumbing leakscontributing to moisture.
Store ripe produce in sealed containers. Clean countertops, floors, and appliances thoroughly to remove sugary spills, crumbs, and other debris.
Prevent Tiny Black Bugs From Coming Back
Once you’ve succeeded in removing an infestation, there are several key steps to take in order to keep tiny black insects out of your house in the future:
-
Pour boiling water down bathroom and kitchen drains weekly to eliminate scum where drain flies breed.
-
Install fine mesh screens over vents, drains, windows, and doors to block entry points.
-
Clear gutters and direct downspouts and drainage away from your home’s foundation.
-
Remove piles of compost, leaves, firewood, and other moist organic matter near your home’s perimeter.
-
Fix leaky plumbing and water damage that allows moisture into walls, basements, or crawlspaces.
-
Clean all drains weekly with soap and hot water to remove scummy buildup.
-
Allow potted plant soil to dry out between waterings and repot plants into clean containers every few years.
-
Take out trash and recycling daily. Rinse cans and bottles before recycling.
-
Keep kitchen and bath areas clean and dry. Wipe up spills right away.
-
Use dehumidifiers and fans to keep basements and crawlspaces dry.
-
Fill small cracks and openings in walls, moldings, and cabinets where bugs can enter.
-
Treat indoor plants and surrounding soil monthly with insecticidal soap or neem oil.
With diligent sanitation and pest-proofing tactics, you can keep tiny black crawling insects and worms out of your home for good. Get into the habit of cleaning and drying damp areas, removing organic waste promptly, and sealing up pest entry points. Follow up with traps and targeted treatments at the first signs of bugs to prevent infestations from developing.
When To Call An Exterminator About Tiny Black Bugs
While small black fly and worm invasions can often be controlled with thorough DIY methods, it may be time to call a professional pest control company if:
-
Infestations last longer than 2-3 weeks despite intensive cleaning and treatments.
-
You live in a multi-family building where pests may be moving between units.
-
You notice stains or structural damage from excessive moisture contributing to bugs.
-
Drain pipes are leaking or damaged, causing persistent drain fly issues.
-
There are large piles of compost or extensive landscaping right against the home’s exterior.
Licensed exterminators have industrial-strength products and methods to fully eliminate heavy infestations. They can also identify and remedy conditions in a home’s structure that allow pests to thrive.
In some cases, major plumbing repairs and moisture remediation may be required to get a severe bug problem fully under control. The investment is well worth it for long-term elimination of annoying and potentially unhealthy pests.
The Takeaway On Removing Tiny Black Bugs and Worms
Don’t let small black crawling insects and worms ruin the clean, comfortable environment in your home. With consistent drain cleaning, prompt organic waste removal, moisture control, and pest-proofing tactics, you can get rid of existing infestations and prevent new ones from developing.
Implement targeted treatments at the first signs of bugs like vacuuming, drain treatments, natural insecticides, traps, and commercial pesticide sprays. Call in professional pest control reinforcement if DIY options repeatedly fail.
Taking action to get rid of tiny black pests and keeping them out for good provides lasting peace of mind. You and your family will be able to enjoy your living spaces again, free of bothersome bugs darting through the air or worms wriggling across floors.
Common Characteristics of Millipedes
• Active at night and found throughout the United States, these harmless insects prefer damp places.
• Most millipede species are brown or black, but some are orange or red.
• Most millipedes are between 1 and 2 inches long, and their bodies look like worms and are made up of many segments, each with two pairs of legs.
• While their name means “thousand legs”, this arthropod doesnt actually have that many (80-400 is typical.)
• It looks like their legs move in waves when they walk, and they curl up into a small coil when they rest or are scared.
Outdoors: Millipedes like to hide in damp, dark places.
- Under mulch
- Leaf piles
- Compost piles
- Flower pots
- Wood piles
- Under stones
- Plant debris
Indoors: Millipedes are attracted to cool, damp places like the basement, crawl spaces, or the garage.
Millipedes are decomposers and are beneficial to have around your yard. Similar to earthworms, millipedes eat damp, decaying plant material such as leaves and flowers. Millipedes have been known to eat living plants during dry times so they can get the water they need from the leaves and roots.
