I've been told (by the local extension office) that bee's can pick up AMDRO. They recommended covering the ant hill with a tarp or large sheet of plastic until they've taken all the AMDRO into the hive.
Normally you spread Amdro on your whole property (homeplace) at the rate of a pound per acre, which it is reccomennded to use a hand held garden broadcast spreader (the plastic garden/yard type), set at it's lowest setting, as the ants travel in undergropund burrows they have dug up to a couple of hundred feet long in all directions around their mound/coloney seeking food. If you are afraid of the bees picking it up, you would be better to treat just the mound, and cover with a tarp.
But the problem then is that you will only destroy that mound/coloney, and you have many more ant homes/burrow/villages/coloneys, what ever you want to call them, that exsist without making a mound. You have more ants that do not make a mound, than you have that do make mounds. and the only way to reallly control the fire ant is to spread the bait over the whole property.
I have had neighbors say they do not have fire ants, because they do not see any mounds. Well, they are badly mistaken, if you live in my area, you do have fire ants, unless you treat both spring and fall with Amdro, or a similer bait. They are just not building any mounds where you are seeing them. If you live im my area, and do not treat for them systamatically, I can find fire ants on your property, and if your neighbors do not treat regularly, you are constantly being reinfested by their ants colonys.
Also if you live in an area that is to cold for them, they will eventually get to you, as they become acustomed to the cold and adjust, as it is natures way.
It may help some, that they have released an imported fly, that lays an egg in their head, which kills them (if the cure does not turn out to be worse than the ant).
I am told the armadillo, is slowly adjusting to the weather, and moving into our area, which I understand they are ant eaters, maybe they will be a godsend for us here.
