Terro T300 Liquid Ant Baits

Name: Terro T300 Liquid Ant Baits
Brand: Terro
Rating: 4.8 (5 reviews)

$8-$15

Terro T300 has built a loyal following among homeowners who report that patience is the key to its colony-killing payoff, with one user describing how “all the ants filled the baits and died inside” after the entire colony followed the bait trail. Most users confirm it takes time for the borax to work through the nest, and those who stick with it note “those baits do a good job and I've had success with them every year”. However, a vocal contingent on r/pestcontrol has flagged a potential red flag: “the new stuff doesn't work at all”, with users pointing to a recent formula change as the culprit. For heavy infestations, the economics can also sting, since the bait “may need to be replaced every three days, which could get expensive”.

From the community

those baits do a good job and I've had success with them every year.

From the community

all the ants filled the baits and died inside. I guess the entire colony followed because I have two baits that are filled with dead ants.

What holds up

Unanimously recommended by homeowners across multiple Reddit communities
Slow-acting borax poison targets and eliminates the entire colony, not just foragers
Easy to use, just place where ants are seen and let them do the work
Widely available at most hardware and grocery stores

What to know

Seeing ants swarm the bait before dying can be unsettling before results kick in
Bait stations can be knocked over by robot vacuums, causing spills
Takes a couple of days before you see results, not an instant fix

Bottom line ★

If you buy from current stock and catch the infestation early, Terro T300 can wipe out an entire colony in a single treatment cycle, as evidenced by users finding their bait stations literally filled with dead ants after the colony followed the trail back.
