A:  Hi Matt, Our products including the Amdro Fire Ant Bait has a shelf life of three years. Thank you.

A:  I have used a large container the next season but it does not seem to be as attractive to the nest. Just my observation not a study.

A:  This is my experience with this product. I don't use a whole bottle of it in one season so I make sure the lid is tightly secure and store it in a cool dry place. I have used it for three seasons and it work just as good three seasons later as the first. This will be my fourth season and I'll be using it up this go round. Hope this helps.

A:  I've used it for several years after opening with no apparent loss of effectiveness.

A:  Short answers: Not immediately. And yes. Amdro loses its attractiveness to ants (and hence effectiveness) as it goes 'stale'. That said, I have opened and unopened Amdro in the barn that is several years old, and it still works. I always seal my open working container with a piece of plastic under the screw-on cap (like a sandwich bag, or piece of plastic wrapping) to keep moisture out. I have tried to carefully peel the existing foil seal and push it back into the cap, but my success on that procedure is limited.

A:  I have had mine two years and it still is very effective.

A:  I have used it for several years after opening with the same as new effectiveness.

A:  I've only used it when it was dry. I put a few grains at the entrance to the ant colony, and the worker ants picked it up immediately and took it inside. If any grains remain outside within a few minutes, it probably means you've used too much. A small amount works well. I've only used it when the worker ants are moving around outside. I wouldn't use it when it is raining or wet.

A:  Hello, The Amdro Fire Ant Bait granules are made from a corn grit granule. If that granule gets wet it may no longer be appealing to the ants and may be ignored. We do not recommend applying it when the ground is soaking wet or if heavy rains are expected. Thank you

A:  Rain will wash it away. Wait for a dry spell. Ground should be dry with low chance of rain for at least 5 to 7 days. IMHO

A:  I would not use it when rain is forecast within two or three days as it is meant to be taken into the nest dry.

A:  You have to reapply after it rains.

A:  Nope I don't think it would effect the tree.

A:  Don't know about a new planted tree, but I used it along a 15 ft bed that had bromeliad plants. It killed the red ants and the plants are all fine.

A:  Not that I am aware of, I sprinkle it around shrubs and othe plants and trees and have not had any suffer from it. I would suggest reading the label.

A:  I have had to re-apply this ant bait as ants will relocate their mounts but it has not affected any vegetation, but please consult the manufacture's website or customer number.

A:  You shouldn't have to use very much, not enough to hurt the tree.
