Active Ingredient
Amdro Fire Ant Bait granules contain Hydramethylnon (0.73%) as the primary active ingredient. At the same time, Amdro Ant Block Home Perimeter Ant Bait has a slightly higher concentration, with Hydramethylnon constituting 0.88% of the product.

Mode of Action
Both products are designed to deliver delayed action, typically eliminating the queen within a week and the entire colony within two weeks.

However, Amdro Fire Ant Bait is often considered more effective since it ensures the poison is shared with all colony members, thus guaranteeing the complete extermination of the colony.

Both Amdro Fire Ant Bait and Amdro Ant Block manifest their effects within a week, initiating with the queen’s death and culminating in colony eradication within two weeks.

Targeted Pests
The Amdro Fire Ant Bait primarily targets imported fire ants, native fire ants, Argentine ants, bigheaded ants, and harvester ants.

Contrastingly, Amdro Ant Block has a wider spectrum of targeted pests, killing 25 ant species that include all those targeted by Amdro Fire Ant Bait and more.

Where To Use
Amdro Fire Ant Bait is typically used for outdoor infestations, while Amdro Ant Block Home Perimeter Ant Bait can be applied outside to block ants from entering the house. For indoor infestations, using AMDRO products specified for indoor use is recommended.

Neither of the two products should be applied while pets are in the treatment area. Pets can return once the dust has settled. Moreover, treated lawn or sod clippings should not be used as grazing fodder for livestock after using these products.

How To Use
Amdro Fire Ant Bait can be sprinkled using a disposable spoon, with 2 to 5 level tablespoons spread around the mound without disturbing it. There’s no need to water it in after application.

Conversely, Amdro Ant Bait requires a 12-inch-wide band around the home perimeter, focusing on visible ant trails and potential entry points. This bait can also be sprinkled directly onto and around the mound using a disposable spoon or measuring cup.

Best Time To Apply
Both Amdro Fire Ant Bait and Amdro Ant Block are best applied during cool early morning or early evening hours when ants are most active. They should not be used when the ground or grass is wet or when temperatures are below 50°F.

Our Observation
Given the wider range of ant species targeted and the slightly higher active ingredient concentration, Amdro Ant Block is arguably the more potent product. However, the Amdro Fire Ant Bait’s efficiency in delivering the poison throughout the entire colony gives it a certain edge.

It’s essential to match the product’s choice to your situation’s specific needs. For instance, Amdro Fire Ant Bait is a superior choice if you’re dealing with a fire ant problem. On the other hand, Amdro Ant Block provides comprehensive control for a broader array of ant species, making it an ideal option for mixed ant infestations.
