Why You Keep Seeing Ants in Your Home in Brevard County (And How to Stop the Colony)

If you keep seeing ants in your home in Brevard County, the ants you see are only the workers. The colony is somewhere else, often outside in the yard or inside a wall, and it keeps sending more. Wiping the trail or spraying the line stops that day's ants, not the nest.

TL;DR

Ants on your counter are workers from a hidden colony. Killing the visible ones does not touch the queens.
Ghost ants, white footed ants and crazy ants all have many queens in one colony.
Trail sprays are a quick fix that does not reach the queen. Bait reaches the whole colony, so bait is the usual tool.
Fire ants are different. They nest in mounds in the soil and come inside mostly when the ground floods.
Wet wood, leaks and plants against the house keep the trail coming back.

Why do ants keep coming back to my kitchen?

Ants want three things: sugar or protein, water, and a dry place to nest. A Florida house offers all three all year. We do not have a winter that shuts ants down, so a colony that finds your kitchen keeps visiting.

Scouts find a crumb, go home, and leave a scent trail. Then the line forms. The trail is the only part you see. The nest can be out in a flower bed, in a potted plant, or in a wall void behind the sink.

Which Florida ants am I looking at?

The kind of ant decides what works. These are the ones people in Melbourne and Palm Bay describe most. In a UF/IFAS survey of samples that Florida pest control operators sent in, fire ants, ghost ants and crazy ants tied at 14 percent each.

Ghost ants. Tiny, about 1.3 to 1.5 millimeters, with a dark head and a milky white rear and legs. They are hard to see. UF/IFAS says colonies have many queens, nest in wall voids, cracks and potted plants, and start new colonies by budding, when queens leave with workers.

White footed ants. About 3 millimeters, black bodies, pale feet. UF/IFAS lists them as a major household pest in Florida, and they live mostly in trees and shrubs. They love sweets and honeydew.

Caribbean crazy ants. Fast, erratic, reddish brown, under an eighth of an inch. UF/IFAS says crazy ant colonies have many queens, make no mounds, and nest under leaf litter, stones, pots and debris. They can short out electrical equipment.

Fire ants. They build soil mounds, often near slabs, driveways and foundations. UF/IFAS says a pustule usually shows up the day after a sting, and that they may move indoors when soil is soaked.

Why spraying the trail does not fix it

A colony with one queen is simple. Kill the queen and it ends. Ghost ants, white footed ants and crazy ants do not work that way. They have many queens spread over many nests, and parts of the colony swap workers.

UF/IFAS calls a trail spray a quick fix. It kills the workers it touches. It does not reach the queens, which stay deep in the nest and keep laying. For crazy ants, UF/IFAS says a single spray lasts only two to three days. Ghost ants also spread by budding: queens leave with a group of workers and start a new nest. So a colony with many queens can keep growing and spreading while you wipe up the line.

That is why ant control leans on slow bait. Workers carry bait home and feed it to the colony. UF/IFAS says baits reach the whole colony. A fast spray kills the workers first, so nothing gets carried home.

What we see in Brevard

Ghost ants are the small pale ants in Melbourne kitchens and bathrooms, often near a leak or a potted plant by a window. White footed ants follow the palms, oaks and shrubs that touch the roof and walls. Crazy ants are the ones that show up in huge numbers around lanais, meter boxes and outdoor outlets. Fire ants are in the lawn and along the driveway, and they come in after a heavy rain.

The season has a shape. Technicians here say ants are quiet in January and February, start to ramp up in March and April, and peak in May and June, when the first wet season rains arrive. That is a field observation, not a county count. If your trail shows up in spring, expect it to get busier, not quieter.

Busy ant trails can look worse for a few days after a treatment. We explain why in why you see more bugs after pest control treatment.

What to do now

Follow the trail and note where it comes in and where it starts. Do not smear it away. That is the only map you have.
Wipe up sweets, grease and pet food at night, and seal food in containers.
Fix drips and wet spots. Moisture brings ants and wood damage with it.
Trim shrubs, palm fronds and branches off the roof and walls, and pull mulch back from the slab.
Do not spray the trail. Take a photo of the ant, or catch a few in a bag, so a technician can name the species.

When to call somebody

Call if the trail returns after a couple of weeks, if you see ants in several rooms, or if they are in outlets or switches. Bring the photo. The species decides the plan, and a many-queen colony is hard to beat from the kitchen side. Our general pest control page explains what a visit covers, and the estimate is free. If you also see winged ants or sawdust near wood, check termite warning signs.

Frequently Asked Questions

Why do I keep seeing ants in my house even after I wipe them up?

The ants you see are workers from a hidden colony, often outside in the yard or inside a wall void. Wiping them up does not touch the queens, so the colony keeps sending more.

Does spraying an ant trail get rid of the colony?

Not usually. UF/IFAS calls a trail spray a quick fix that does not reach the queen. Baits reach the whole colony, because workers carry them home and feed them to the nest.

What kinds of ants are common in Brevard County homes?

Ghost ants, white footed ants, Caribbean crazy ants and fire ants. In a UF/IFAS survey of samples from Florida pest control operators, fire ants, ghost ants and crazy ants tied at 14 percent each. Ghost ants have many queens and spread by budding.

When are ants worst in Brevard County?

Technicians here say ants are quiet in January and February, ramp up in March and April, and peak in May and June with the first wet season rains. That is a field observation, not a county count.

Why do fire ants come inside?

Fire ants nest in soil, often near slabs, driveways and foundations. UF/IFAS says they may move indoors when the soil is soaked.
