When it comes to household pests in Indianapolis, ants are among the most persistent invaders. Understanding which species you're dealing with is the first step toward effective control. At Trio Pest Control, we've encountered virtually every ant species in the region. Here's our guide to the most common ants in Indianapolis and how to identify them.
Odorous House Ants
These are perhaps the most common household ants in Indianapolis.
Identification features:
- Size: 1/16 to 1/8 inch long
- Color: Dark brown to black
- Distinctive trait: When crushed, they emit a rotten coconut-like smell
- Form trails along baseboards, countertops, and other surfaces
Odorous house ants are particularly attracted to sweet foods and can establish large colonies with multiple queens, making them difficult to eliminate without professional help.
Carpenter Ants
These larger ants are concerning because they can cause structural damage to your home.
Identification features:
- Size: 1/4 to 1/2 inch long (one of the largest ant species)
- Color: Usually black, but some species have reddish or yellowish coloration
- Distinctive trait: Smooth, rounded thorax when viewed from the side
- Often found near damaged or moist wood
Unlike termites, carpenter ants don't eat wood but excavate it to build nests. Finding sawdust-like material (frass) near wooden structures is a telltale sign of infestation.
Pavement Ants
These ants commonly nest under sidewalks, driveways, and foundation slabs.
Identification features:
- Size: 1/8 to 1/16 inch long
- Color: Dark brown to black
- Distinctive trait: Parallel lines on head and thorax
- Often seen emerging from cracks in pavement
Pavement ants are opportunistic feeders that will consume almost anything, from sweet foods to protein-rich items.
Pharaoh Ants
Though smaller than other species, Pharaoh ants can be particularly troublesome in Indianapolis homes.
Identification features:
- Size: Extremely small, about 1/16 inch long
- Color: Light yellow to red with darker abdomen
- Distinctive trait: Two nodes between thorax and abdomen
- Do not follow visible trails like other ant species
Pharaoh ants are concerning because they can spread disease organisms in their travels through homes. They're also notoriously difficult to control due to their habit of "budding" – creating new colonies when disturbed.
Acrobat Ants
Named for their ability to raise their abdomen over their head when disturbed.
Identification features:
- Size: 1/16 to 1/8 inch long
- Color: Light brown to black
- Distinctive trait: Heart-shaped abdomen when viewed from above
- Often nest in moist or decaying wood
Acrobat ants commonly enter homes through tree branches touching the roof or utility lines.
Prevention and Control Tips
- Seal entry points: Caulk cracks and crevices around foundations, windows, and doors.
- Eliminate food sources: Clean up spills promptly, store food in airtight containers, and take out trash regularly.
- Reduce moisture: Fix leaky pipes and ensure proper drainage around your home.
- Trim vegetation: Keep trees and shrubs trimmed away from your home's exterior.
- Professional treatment: For persistent infestations, professional pest control provides the most effective solution.
