Sugar Ants in Texas
Sugar ants aren't a single species. In Texas, the name usually means the pharaoh ant, a tiny orange-tan ant with a sweet tooth, though people also call odorous house ants and ghost ants sugar ants. All of them are small, march in thin lines to sweets and water, and nest inside walls or close to the house.

What Are Sugar Ants?
"Sugar ant" is a nickname for any small ant that shows up around sweet food. Texas A&M AgriLife entomologists note that pharaoh ants earned the name from their taste for sugary foods. Australia has a true sugar ant, a large banded carpenter ant, but it doesn't live in the United States, so it isn't the ant on your counter.
Because the name covers several species, the first step is working out which one you have. The ants look alike at a glance, yet they nest in different places, and the right treatment depends on where the colony lives.
Sugar Ants in Texas by Species
The table below compares the ants Texans most often call sugar ants, plus the rover ant, which people confuse with them. Size and color are the quickest clues, so a flashlight and a close look go a long way.
| Ant | Size and color | Best clue | Where it nests |
|---|---|---|---|
| Pharaoh ant | About 1/16 inch, light tan to orange | Trails going in and out of outlet covers | Behind walls, under appliances and carpet |
| Odorous house ant | About 1/8 inch, brown to black | Smells like rotten coconut when crushed | Soil under stones and mulch, wall voids |
| Ghost ant | Under 1/16 inch, dark head, pale body | Dark specks moving on sinks and counters | Gaps behind cabinets and baseboards, potted plants |
| Rover ant | Very small, dark brown to almost black | Crowds onto pet food more than sugar | Leaf litter in gutters, under concrete, damp walls |
Pharaoh ants are the ones most likely to live entirely indoors. They settle in wall voids, light fixtures and cracks near warmth and water, which is why they turn up in kitchens and bathrooms in any season. Odorous house ants and rover ants mostly nest outside and come in to forage.
Why Sugar Ants Come Inside
Food brings them in, and water keeps them coming. A drip of juice, a sticky syrup bottle or a pet bowl left out overnight is enough to start a trail. Once a scout finds food, it lays a scent trail back to the nest, and within hours a line of workers follows it.
DFW summers add a second reason. During long hot, dry spells, ants move indoors in search of water, according to AgriLife Today's report on pests moving indoors during drought. A leaking faucet, a sweating AC line or a damp cabinet under the sink can draw ants even from a spotless kitchen. Fixing those leaks matters as much as wiping the counters.
Why Spraying Makes Sugar Ants Worse
Spraying the trail feels like the fix, but with pharaoh ants it often backfires. A pharaoh ant colony has many queens, and when a spray stresses it, the colony splits into several new ones. Texas A&M AgriLife's school IPM article on pantry ants warns that spraying likely leads to more ants in more locations, and it names ant baits as the best control.
Baits work because workers carry them back and feed them to the rest of the colony, queens included. A small dab of gel bait is plenty. Our technicians treat a colony directly when they can reach it. Otherwise they use baits along with non-repellent sprays that ants don't avoid, so foragers carry the product home without scattering. That approach takes longer than a spray, but it ends the colony instead of moving it.
How to Get Rid of Sugar Ants
These steps work for every ant in the table, and they matter most for pharaoh ants.
- Wipe each trail with soapy water to remove the scent the ants follow.
- Store sweets, cereal and pet food in sealed containers, and pick up pet bowls at night.
- Fix leaks under sinks and around AC lines so the ants lose their water source.
- Place small amounts of ant bait along the trail, out of reach of children and pets, and leave the ants alone while they feed.
- Skip repellent sprays and foggers, which scatter pharaoh ants into new colonies.
If the trails keep returning after two or three weeks of baiting, the colony may sit in a wall void or another spot the bait isn't reaching.
Are Sugar Ants Harmful?
Sugar ants are mostly a nuisance. They don't sting, and pharaoh ants seldom bite. The bigger concern is where they travel. Texas A&M notes that in hospitals, pharaoh ants can carry more than a dozen kinds of disease-causing bacteria. In a home, that means ants walking from drains and trash to your counters, so toss any food they reach.
Sugar Ants FAQ
Do sugar ants bite?
Rarely. Pharaoh ants and odorous house ants don't sting, and a bite, if it happens, is too small to notice. If tiny ants are stinging you outdoors, you're more likely dealing with fire ants.
What attracts sugar ants?
Sugar, syrup, fruit and grease attract most of them, and water draws them in during dry weather. Rover ants prefer protein, so they gather on pet food and meat scraps.
How long does it take to get rid of sugar ants?
Baits usually take days to a few weeks, because the workers need time to carry them back and share them through the colony. You may see more ants at the bait at first, which is a good sign that they are taking it home.
