Remove flying ants from wall cavities using bait traps, sealing entry points, and targeted insecticides.

Flying ants in wall cavities indicate a nearby colony. To eliminate them, use ant bait traps to target the queen, seal cracks and gaps to prevent entry, and apply insecticidal dust or foam into wall voids. For severe infestations, professional pest control may be necessary to ensure complete removal.

Identify the source of flying ants

• Check for swarms near windows, vents, or light sources
• Listen for rustling sounds inside walls
• Look for frass (wood shavings) or dead ants near baseboards

Effective removal methods

Prevent future infestations

• Seal cracks around windows, doors, and foundation
• Repair leaky pipes to reduce moisture
• Keep food sealed and clean up spills promptly

When to call a professional

If DIY methods fail after two weeks or if you notice structural damage, contact a licensed exterminator. They can use specialized equipment to treat deep wall voids and identify hidden colonies.
