Best Ant Bait: Liquid, Gel, and Granules Matched to the Ant You Have

Direct answer. For sweet-feeding house ants such as odorous house ants and pavement ants, start with Terro Liquid Ant Bait. The six-pack of bait stations typically costs $8-13, and it is the default first try. Expect the bait flood to look worse for 2-3 days because it is working; killing the visible ants with spray resets the whole job. For cracks where stations do not fit, Advion Ant Gel at 0.05% indoxacarb is a $25-35-class option. Fire ants outdoors need a different product: Amdro Fire Ant Bait granules, $15-25 class per bag.

Best Ant Bait: Liquid, Gel, and Granules by Ant Type

How these picks were made

Picks are based on the product label, active ingredient, and published pricing. This site does not run a lab. Prices are typical US ranges checked in November 2026 and vary by retailer and region.

Match the bait to the ant

Bait type matters more than brand. Terro Liquid Ant Bait is borax-based, with sodium tetraborate at 5.4%, and it fits sweet-feeding house ants. The six stations are cheap enough to try first, and the liquid format lets ants take bait back to the colony. The honest warning is that visible activity can increase for 2-3 days. That is not a reason to spray. Killing the visible ants with a repellent spray resets the job and can split the colony.

Advion Ant Gel is the gel-placement option at 0.05% indoxacarb, typically in the $25-35 class. Use it in cracks and crevices where bait stations do not fit. It is not a replacement for choosing the right bait type; it is a delivery format for the same kind of crack-and-crevice work. Follow the label for placement and dose.

Amdro Fire Ant Bait granules use hydramethylnon and are in the $15-25 class per bag. This is an outdoor fire ant product, applied as a broadcast or mound treatment per the label. Apply dry and never before rain. Fire ants are a separate job from house ants; see fire ant control cost for the service and product cost picture.

Optigard Ant Gel, with thiamethoxam, is the rotation option when a colony ignores the first bait. Ants that will not eat a sweet bait may be protein-feeding, so bait type—sweet versus protein—matters more than brand. Rotate after a fair trial, not after one day. If the ants are not taking the sweet liquid at all, do not keep adding more of it.

Carpenter ants are a different problem

Carpenter ants are not a good candidate for a bait-only plan. Bait is slow and unreliable on them. The real issue is usually an inspection and moisture problem—finding the nest, the wet wood, and the entry path. Treating what you see with bait or spray can miss the colony. If carpenter ants are the target, use the carpenter ant treatment cost guide and plan for inspection and moisture correction, not just a bait station.

How to run a bait job without wasting money

• Place stations or gel where ants are traveling, not randomly around the room.
• Do not spray the trail. The bait flood can look worse for 2-3 days because it is working.
• Give the label’s trial period before rotating. If a sweet bait is ignored, consider protein-feeding ants and change bait type.
• Keep bait out of reach of children and pets, and follow the label for indoor and outdoor use.

Cost is not the main variable here. An $8-13 Terro pack is cheap enough to test the sweet-bait theory first. Advion Ant Gel costs more but solves placement in cracks. Amdro is a separate outdoor fire ant purchase. The expensive mistake is spraying a trail and resetting the job, or buying a second bait before confirming what the ants will eat.

Safety and price note

Follow the product label. Keep children and pets away from bait placements. Some ant products are restricted in some states; check the label and state rules before ordering. Prices were checked in November 2026 and vary by retailer and region.

Verdict

For sweet-feeding house ants, buy Terro Liquid Ant Bait first. For cracks where stations do not fit, use Advion Ant Gel. For outdoor fire ants, use Amdro Fire Ant Bait granules and apply dry, never before rain. Keep Optigard as the rotation option when the first bait is ignored. Skip bait as a primary plan for carpenter ants; that is an inspection and moisture job.
