TERRO Liquid Ant Baits T300

Borax-based liquid bait that worker ants carry back to the nest, so it ends the infestation rather than just killing the ants you can see, which is the most common indoor pest job.

Not for: Homes with roaches, fleas, bed bugs or flying insects, which this does not treat, and homes where pets or toddlers can reach and chew the bait stations.

TERRO Liquid Ant Baits (line)

Ready-to-use bait lets foraging ants carry slow-acting borax back to the colony, targeting more than just visible ants.

Not for: Other pests, grease-loving ants, or placement accessible to children and pets.

Which one fits you

cockroaches

Syngenta Advion Cockroach Gel Bait (line)

Professional-grade gel bait that roaches eat and spread to others in the harborage, which outperforms sprays on German cockroaches.

Not for: Anyone dealing with ants, or anyone unwilling to place bait in cracks and hinges rather than spraying open surfaces.

flying insects with no chemicals

Zevo Flying Insect Trap (line)

Plug-in light and sticky-pad trap that catches fruit flies, gnats and house flies without spraying anything in living spaces.

Not for: Crawling-insect problems, or anyone unwilling to keep buying replacement cartridges.

Check before you buy

Bait vs. spray. Use slow-acting baits for social insects (ants, roaches). Use sprays for perimeter barriers and individual insects. Fast contact kill keeps the poison from reaching the colony. Repellent sprays can also make ant colonies split and spread.
Target pest on the label. The label must list your pest and indoor use. Ant baits are formulated for ant feeding preferences and often fail on roaches, and the reverse is also true.
Placement and patience. Put bait on active trails and harborage points. Do not spray near the bait. Expect several days to a couple of weeks for results. More ants at the bait at first means it is working. Spraying contaminates the bait and ruins the result.
Pet and child exposure. Prefer enclosed, tamper-resistant stations or crack-and-crevice gels where pets and children can reach. Open liquid and gel baits can be licked or chewed.

What to avoid

Spraying an ant trail where you have also placed bait.
Treating bed bugs or termites yourself as a first step instead of getting a professional inspection.

Questions

Why are there more ants after I put out bait?

The ants are recruiting nestmates to the food source. Leave the bait alone and the numbers should drop within days.
