The details

This ant killer has become a popular choice because it exterminates ants in their hideouts within 2-3 days. It uses borax to poison ants, but it doesn’t kill them immediately. Ants consume and carry it to other ants. Thus, it exterminates numerous ants at once and that’s why it’s the best ant killer.


Borax slowly affects the digestive system of ants to kill them. It takes a little time, but that time is necessary to target the entire colony of ants.

Ease of use

People choose this ant killer because it is super easy to set-up anywhere across the home. It takes just five minutes to set the bait stations inside or outside the house.

Value for money

One bait station targets numerous ants and exterminates them. 12 bait stations would make your home an ant-free home for several months.


It’s probably the most affordable ant killer because you get 12 ant killing bait stations for indoor and outdoor use.

Final verdict

If you want to use an ant killer that kills hundreds of ants in 2-3 days, you should choose TERRO T300B. Be a little carefully when setting up the bait station! Borax liquid will lure ants and slowly kill them in their hideouts.
