Ant Control Guide 2025: Species, Treatment Methods & Prevention
Ants are the most common household pest, with over 12,000 species worldwide. While most are nuisance pests, some species like carpenter ants and fire ants can cause significant structural damage or health concerns. Understanding ant biology and behavior is essential for effective control.
Common Ant Species
Carpenter Ants
Large black ants (6-13mm) that excavate wood for nesting—not for food. Unlike termites, they don't eat wood but create smooth galleries. Found in moist, decaying wood near windows, doors, and plumbing.
Warning Signs: Sawdust piles (frass), rustling sounds in walls, winged swarmers in spring. Damage Potential: Significant structural damage if untreated for years.
Fire Ants
Reddish-brown ants (3-6mm) that build large mound nests and deliver painful, venomous stings. Aggressive when disturbed. Common in southern US, spreading northward.
Health Risk: Stings cause painful welts; severe allergic reactions possible.
Odorous House Ants
Small brown ants (2-3mm) that emit a rotten coconut smell when crushed. Form large colonies with multiple queens, making them difficult to eliminate.
Pavement Ants
Small dark brown ants (2.5-4mm) nesting in cracks in pavement and foundations. Common invaders seeking sweet and greasy foods.
Pharaoh Ants
Tiny yellow ants (1.5-2mm) that form massive colonies. Major problem in hospitals and food facilities due to disease transmission potential.
Signs of Ant Infestation
- Ant trails along baseboards, windowsills, and counters
- Small piles of soil or debris near nest entrances
- Wood shavings (carpenter ants)
- Mounds in yard (fire ants)
- Winged ants indoors (swarmers)
Professional Treatment Options
Baiting Systems
The most effective approach for most ant species. Worker ants carry bait back to the colony, eliminating the queen and entire population.
Types: Gel baits, granular baits, bait stations Effectiveness: 90-100% colony elimination Timeline: 2-4 weeks for full effect Cost: $150-$300
Perimeter Treatment
Liquid insecticides applied around foundation create a protective barrier.
Best for: Preventing outdoor ant entry Cost: $100-$250 per treatment Duration: 2-3 months protection
Carpenter Ant Treatment
Specialized treatment including:
Cost: $300-$800 depending on severity
Fire Ant Treatment
Mound treatments and broadcast applications:
Cost: $100-$400 for typical yard
DIY Ant Control
Bait Stations
Consumer ant baits work well for minor infestations. Place near trails and entry points. Allow 1-2 weeks to work—don't spray where baits are placed.
Natural Remedies
- Diatomaceous earth in cracks and crevices
- Peppermint oil as deterrent (not elimination)
- Vinegar to disrupt trails (temporary)
When to Call Professionals
- Carpenter ants present
- Fire ant infestation
- Infestation persists after 2 weeks of DIY treatment
- Ants returning repeatedly

Frequently Asked Questions
Why do ants keep coming back? If you only kill visible ants, the colony remains active. Effective control requires eliminating the queen through baiting.
Are ant sprays effective? Sprays kill contact ants but often cause colony budding, creating multiple new colonies. Baits are more effective long-term.
How long does ant treatment take? Baits take 2-4 weeks to eliminate colonies. Spray treatments provide immediate knockdown but don't address the source.
Can ants damage my house? Carpenter ants can cause significant structural damage over time. Other species are nuisance pests only.
