Both Terro Ant Bait Gel and Amdro are used to kill ants. They work in slightly different ways, but they have the same effect of killing ants when eaten by them. The only exception is that while Amdro will not spill outside its range if it remains dry, Terro can do so as long as it is kept wet with water or any other liquid substance.

Comparing these products side-by-side for their pros and cons makes one thing clear: you choose whichever works best for your needs! If you want something quick acting that does not leave a mess behind then go with Terro. But if prefer an insecticide product that has more bait options than just sweet syrup then stick with Amdro instead of the Terro ant killer.

Short Review of Terro

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

Short Review of Amdro

Amdro can be used indoors as well as 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.

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 behind, 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, then 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 it can be used only outside. Terro ant killer doesn’t work as well on all types of ants, so you should also determine what type of ant you have before deciding which one to use.

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