Amdro Fire Ant Bait is a ready-to-use granular fire ant killer designed to eliminate entire fire ant colonies including the queen. This dual-action formula attracts ants with corn grit-based bait that worker ants carry back to the mound as food. The product contains 0.73% hydramethylnon as the active ingredient, which provides relatively fast control within 2-6 weeks.

The bait is effective against imported fire ants, native fire ants, Argentine ants, bigheaded ants, and harvester ants. For individual mound treatment, apply 2-5 level tablespoons in the area extending 1-3 feet around the mound without disturbing it. For broadcast application, use 1-2 pounds per acre or 2-4 ounces per 5,000 square feet. The product works best when applied in early morning or late afternoon when ant activity is at its peak, and should not be applied when the ground is wet or heavy rain is expected. Do not water in after application as moisture makes the bait soggy and less appealing to ants.

This product is labeled for use in landscaped areas, ornamental and flower gardens, and grounds surrounding poultry houses. It should not be used in vegetable gardens, grazing areas, or pastures. While hydramethylnon has very low toxicity to people, animals, and birds when used according to label directions, the product is toxic to fish and should be used with caution near ponds, lakes, or wells.
