Sugar ants are a common spring and summer nuisance, invading homes in search of food and water. While they don’t pose health risks, their persistence makes them a frustrating pest to eliminate.
This guide covers the best DIY and professional solutions to eliminate sugar ants and keep them from coming back.
What Are Sugar Ants?
Sugar ants, or banded sugar ants, are small black ants native to Australia and exclusive to that part of the world. When I think of the term sugar ants, I sometimes think of pavement ants or pharaoh ants—both common household ants. Pavement ants are black or reddish brown with pale legs while pharaoh ants are yellow or light brown.
Another interesting term for sugar ants is odorous house ants because they produce a pheromone when killed that even humans can smell. If you have a sugar ant problem, chances are you’ve smelled this but just didn’t know it.
These ants are attracted to sweet foods and all varieties of sugary foods and scraps. They also eat fats, proteins (obtained from eating other insects), and plant pollen. Once they find a food source, they’ll haul food back to their nest for the rest of the colony.
How To Identify Sugar Ants
There are so many ant species that it can become a challenge to identify one from the other. Let’s break down some of their differences from black ants and other types of ants.
Size and Color
Sugar ants are extremely small, being around 1/8 inch long at most. Their bodies range from light yellowish-brown to reddish-brown in color. They have darker abdomens compared to their lighter colored head and thorax area.
Antennae
Take a close look at their antennae, which have a very distinct build. Sugar ant antennae have a rigid “elbow” joint about 1/3 of the way from the head, with the longer end being the antenna itself. This elbow antenna is a sure giveaway.
Nesting Sites
Inside homes, sugar ants typically nest in warm, moist areas like wall voids, under floors, or around hot water pipes and heating systems. Outside nests are shallow under mulch, stones or sidewalk cracks.
Type
There are several types of sugar ants, including those that live outdoors and come indoors to eat, as well as others that prefer to live and feed inside your home. Outdoor sugar ants can include acrobat ants, false honey ants, or rover ants. Some common indoor sugar ants are carpenter ants, pavement ants, and pharaoh ants.
Where Do Sugar Ants Come From?
Most sugar ants come from outside your home. They have about four to five times more odor receptors than other insects and can smell food and follow scent trails through cracks, crevices, vents, and other openings in your home and foundation.
Only one ant needs to find an entry point. Once an ant finds a food or water supply, it lays a pheromone trail—a basic scent trail—for other ants to follow.
Sugar ants also come from existing nests inside your home. Their nests are typically in undisturbed spaces, such as inside walls or basements.
How To Get Rid of Sugar Ants: DIY Solutions
Before eliminating sugar ants, find their entry point and scent trail. Follow the ants to see where they’re coming from—this will help you stop them at the source.
Once you’ve identified the trail, choose one of these effective methods:
Natural Methods To Get Rid of Sugar Ants
- Vinegar spray – Mix equal parts vinegar and water in a spray bottle and apply along baseboards, counters, and entry points. Vinegar erases pheromone trails so other ants can’t follow.
- Diatomaceous earth (DE) – Sprinkle food-grade DE along ant trails and entry points. This natural powder dehydrates and kills ants on contact.
- Coffee grounds and bay leaves – Scatter used coffee grounds or bay leaves in problem areas. These strong scents repel ants but won’t kill them.
- Homemade ant bait – Mix 1 part Borax with 3 parts sugar water and place it near ant trails. Ants take the bait back to the colony, wiping it out over time.
- Essential oils – Mix water with peppermint, tea tree, or lemon oil and spray around doorways and windows. Ants hate these scents.
Most natural methods work within a few days but require repeated application.

Chemical Methods To Get Rid of Sugar Ants
- Ant baits (best for large infestations) – Use Terro Liquid Ant Bait or similar products. These attract ants, who take the poison back to the colony, eliminating the entire nest.
- Ant sprays – Apply an ant-killing spray along baseboards and around windows/doors. (Avoid using sprays near baits, as they can repel ants from taking the poison back to the colony.)
- Perimeter treatment – Use an outdoor ant barrier spray around your home’s foundation to keep ants from coming inside.
Chemical methods usually show results within 24–48 hours, but bait traps take about a week to fully work.
How To Remove Sugar Ant Nests
If sugar ants are nesting outside your home, destroy the colony before they invade. A sugar ant nest looks like a small mound of dirt with a hole in the center.
Effective ways to eliminate outdoor nests:
- Boiling water – Pour a kettle of boiling water directly into the nest to kill the colony instantly.
- Soapy water – Mix water with dish soap and pour into the nest. This traps and suffocates the ants.
- Baking soda and sugar – Sprinkle a mix of baking soda and sugar over the nest. Sugar attracts the ants, while baking soda kills them.
- Chemical ant killers – If DIY methods fail, use a granular ant killer specifically for outdoor use.
⏳ How long does it take? Boiling water works instantly, while other methods may take a few days.
How To Prevent Sugar Ants From Invading Your Home
Sugar ants are most active in spring and summer, but prevention should be year-round. Here’s how to keep them out:
- Wipe up any sugary messes – Even small spills attract sugar ants. Clean up juice, honey, and syrup immediately.
- Eliminate moisture sources – Fix leaky pipes, wipe up standing water, and keep bathrooms and kitchens dry.
- Routinely clean your sink – Wash dishes promptly, and pour vinegar or bleach down the drain every few days to eliminate food residue.
- Vacuum and sweep daily – Food crumbs are a magnet for ants. Regularly clean floors, especially around the dining area.
- Take out the trash regularly – Use sealed garbage bags and take out the trash before it overflows.
- Seal entry points – Inspect windows, doors, and foundation for cracks and seal them with caulk.
- Use natural repellents – Place bay leaves, cinnamon sticks, or coffee grounds along pantry shelves and entryways.
- Treat your home’s perimeter – Apply a natural pesticide spray around the foundation to create a barrier.
- Call an exterminator if needed – If DIY methods don’t work, a professional can provide a long-term solution.
Final Thoughts
Properly identifying sugar ants is the crucial first step before attempting any control or extermination methods. While they may seem like just another trivial nuisance ant, their unique biology and behavior patterns require a targeted approach.
With their distinctive features like tiny size, elbow antennae, attraction to sweets, and preferred nesting spots, you’ll be able to distinguish sugar ants from other household species.
If you’re still having a hard time dealing with these ants, hiring a pest management company might be the right solution for you.
FAQs About Getting Rid of Sugar Ants
Sugar ants typically invade homes from the outdoors, attracted by food, moisture, and warmth. They have a powerful sense of smell—four to five times stronger than most insects—allowing them to detect even tiny food crumbs.
Once a single scout ant finds a food or water source, it leaves behind a pheromone trail that signals the rest of the colony to follow. These trails can lead through cracks, vents, electrical outlets, and even under doors. If you’re seeing sugar ants, chances are they’ve already established a scent path into your home.
Prevent them by:
- Sealing cracks around windows, doors, and foundation.
- Keeping counters and floors free of crumbs and spills.
- Eliminating moisture sources like leaky pipes or standing water.
Sugar ants don’t cause structural damage like carpenter ants, but they can still create problems.
- Food contamination – They crawl over food, dishes, and countertops, potentially spreading bacteria.
- Pantry invasions – They chew through paper, cardboard, and even thin plastic to access sugar, grains, and pet food.
- Attracting other pests – Their presence can lure spiders, cockroaches, and other insects into your home.
If you notice persistent sugar ants, it’s best to act quickly to prevent a larger infestation.
The fastest way to eliminate sugar ants is a three-step attack:
- Erase the scent trail – Spray a mix of vinegar and water along baseboards, counters, and entry points. This prevents more ants from following.
- Set bait traps – Use Terro Liquid Ant Baits or a homemade mix of Borax and sugar water. Ants take the poison back to their colony, eliminating it at the source.
- Seal entry points – Caulk cracks, fix leaky pipes, and keep your kitchen spotless to prevent re-entry.
Most infestations clear up within a week if you remove food sources and use effective bait traps.
Sugar ants generally prefer warmer, humid environments. This is why the onset of the late spring and summer months often coincides with their appearance in any home. They prefer to nest in holes in wood when outdoors, and will be attracted to wet areas once they’ve made their way inside your home.
No, sugar ants won’t leave on their own. Once they’ve found a food source, their pheromone trail keeps attracting more ants. Without intervention, the infestation will only grow.
To stop them:
- Destroy scent trails – Use vinegar spray to wipe away their chemical signals.
- Remove all food sources – Clean up spills, seal pantry goods, and take out the trash daily.
- Use bait traps – If the colony is large, baits are the best long-term solution.
Ignoring sugar ants only allows the colony to expand, so act fast!
The most widely known outdoor ant extermination technique is to pour boiling water into the nest. An even easier solution could be to pour a full liter of white vinegar into the nest once you’ve found it. This is totally non-toxic to surrounding plants and soil but will kill the ants on contact.
