#1 - Never had to deal with ants when growing in-house

[voyager]

I bought an Ascda. Thai Spots 'Bow' at the Hilo Orchid Show last fall. I was really looking forward to its first blooming. A few weeks after mounting it in a tree it began to bud a flower spike. Before it got even a 1/2" long, I found ants biting into the bud, grabbing onto it with their mouth pincers. I did spread some ant poison pellets around it and the ants seemed to disappear. But the spike bud dried up and died. It has now begun another spike bud. I want to protect it so that it can develop its pretty purple freckled yellow flowers.

After many very painful encounters with the local Little Fire Ant [LFA] population, I began a monthly regimen of spraying my lot with Tango to keep them in check. The fire ants are now bearable, but other types seem to be moving in to replace them.

Will the Tango help to control ant types other than LFA's?
Or, will I need to use other methods to keep them under control also?

Plus, my tree mounted Iwanagaara Apple Blossom had ants all over it right after mounting it. Its flowers faded and died very quickly. I assumed the ants were cultivating scale or aphids and sprayed with Neem Oil as I do with my fruit trees. I don't see ants around it any more, but it hasn't re bloomed yet. I'm suspicious that the ants are still affecting it.

I'm open to any thoughts on the subject.
