Top Feature

  • TERRO is primarily recommended for indoor use, while Amdro has products specified for indoor and outdoor usage (e.g., bait station stakes).
  • TERRO is effective against a specific set of sweet-eating ants. At the same time, Amdro claims to kill various ant species, excluding carpenter ants, fire ants, harvester ants, and Pharaoh ants.
  • TERRO recommends replacing the bait stations every three months, while Amdro recommends replacing indoor bait stations after 3 months and outdoor bait stations after 6 weeks.
  • Both are designed to attract and kill common household ants by allowing worker ants to take the bait back to their colony.
  • Both use a slow-kill method. Ants consume the bait and take it back to the colony, sharing it with other ants, including the queen, which eventually eliminates the entire colony.

Short Review of Terro

Terro Ant Bait Gel also contains Pyrethrum as its active ingredient. Still, it is mixed into a syrupy, sweet-smelling bait that attracts ants and insects to feed on the gel instead of your food or household items. Like Amdro, Terro works by suffocating nearby pests. Still, when eaten by an ant colony, it can quickly eliminate them in their nest via starvation. Both are excellent products for killing ants at home!

Amdro Ant Bait Review

Amdro can be used indoors and outdoors while it works by using powerful hydrocarbon fumes that suffocate any insects nearby (including fire ants). The bait gel formulation allows you to place small amounts where there has been activity without fear of spilling outside its range so long as it remains dry.

This product also contains Hydramethylnon (1.0%), a natural insecticide made from the dried flower of the Chrysanthemum cineraria folium.

  • One 24-ounce bottle covers up to 1,080 linear feet for approximately three months.

Our Observation
The main difference between Amdro and Terro Ant Killer is that Terro is an instant kill, while Amdro takes a little longer to work. However, Amdro will also kill termites, which Terro does not do. Additionally, Amdro leaves no residue, while Terro can leave a sticky mess if it is not applied correctly.

Which ant killer should you choose? It depends on your needs! If you want an instant kill and do not mind a sticky mess, then go with Terro. But if you want an ant killer that also kills termites and leaves no residue behind, go with Amdro instead! Both Terro Ant Bait Gel and Amdro are used to kill ants. They work in slightly different ways, but they are both very effective at getting the job done.

Amdro is an effective product for killing ants and can be used only outside. Terro ant killer doesn’t work as well on all ants, so you should also determine what type of ant you have before deciding which one to use.

If your goal is to kill the colony outdoors, then amdro would be a better choice than terro because it lasts longer outside the elements. But if you want to kill an ant & its colony from inside your home, then terro is the right choice.
