Repeat the process daily until the infestation subsides.

Homemade Ant Traps

Homemade ant traps can lure odorous house ants away from your home.

Borax and Sugar Trap:

Borax: Acts as a slow-acting poison.
Sugar: Attracts ants to the trap.

Steps:

Combine 1/2 cup of sugar with 1 1/2 tablespoons of borax.
Add enough water to create a thick paste.
Place the mixture in small containers near ant activity.
Monitor and refresh the traps as needed.

Vinegar and Water Trap:

Vinegar: Destroys scent trails and kills ants on contact.

Mix equal parts white vinegar and water.
Pour the solution into shallow dishes.
Place the dishes around ant entry points.
Clean up ant carcasses regularly and replace the solution as necessary.

Using these natural remedies can effectively deter odorous house ants, creating a safer home environment. If these methods do not yield results, consider contacting a professional pest control service.

Chemical Solutions

Using chemical solutions can effectively eliminate odorous house ants. When natural methods don’t suffice, consider chemical options to ensure thorough extermination.

Insecticidal Sprays

Insecticidal sprays can provide immediate relief from an ant infestation. These sprays are designed to kill ants on contact and can be used in various locations around your home.

Contact Sprays:

Definition: Sprays that kill ants immediately upon contact.
Usage: Apply directly on visible ants, particularly along trails and entry points.
Examples: Terro Ant Killer, Raid Ant Spray.

Residual Sprays:

Definition: Sprays that leave a lasting residue to kill ants over time.
Usage: Spray along baseboards, around doors and windows, and in areas where ants are frequently seen.
Examples: Ortho Home Defense, Bayer Advanced Ant & Roach Killer.

Precautions:

Ventilation: Ensure good ventilation during application.
Children and Pets: Keep away from areas accessible to children and pets until the spray has dried.
Packaging Instructions: Follow all instructions and warnings on the product label.

Baits and Traps

Baits and traps target ant colonies more effectively than sprays, as they allow ants to carry the poison back to their nests.

Ant Baits:

Definition: Poisonous food that ants take back to their colonies, eventually killing the entire population.
Usage: Place baits near ant trails, entry points, and areas of high activity.
Examples: Terro Liquid Ant Baits, Advion Ant Gel.

Definition: Devices that lure ants in and trap them, often containing a bait inside.
Usage: Set traps in areas where ants are commonly seen.
Examples: Raid Ant Baits, Combat Ant Killing Bait Stations.

Features:

Slow-Acting Poison: Allows ants to share the bait with the colony before dying.
Indoor and Outdoor Use: Suitable for both indoor spaces and outdoor areas like patios and gardens.
Refillable Options: Some baits and traps can be refilled for continuous use.

To maximize effectiveness, inspect and replace the baits regularly, especially if ant activity persists.

Using chemical solutions can efficiently eliminate odorous house ants. Apply these methods responsibly by adhering to safety guidelines for a successful and safe extermination.
