Is Terro Safe for Plants?

I live in the SW desert area, and have been battling ants for 7 years. Some years I win, some years they win. We've had some epic battles over years, and now I'm trying to finally gather a front that will end in at least an armistice.

Every time I find ants in my house, I lay down a blob of Terro (http://www.terro.com/products/liquid-ant-killer). It works well and they never come back to that track.
I've tried Diatomacious Earth outside. And Amdro. Neither have helped, even when I've dumped them around an obvious ant exit point.
What I'm looking to do now is start using blobs of Terro outside in the areas where I can see they're active. I've found that one of their major highways is up a mesquite tree in my back yard.
So, my question is: would Terro damage the tree if globs of it got onto the trunk and branches?
I found one previous meta reference to Borax, but it doesn't really seem to apply in this situation: http://ask.metafilter.com/205638/How-safe-is-Borax
Some more information about Terro and plants: http://answers.yahoo.com/question/index?qid=20120507093239AA5XJxX But I'm not intending to eat the mesquite trees, so I'm not worried about toxins that would make it up to humans if ingested.
The formula for Terro, from their site: Contains sodium tetraborate decahydrate (Borax) (5.40%) and other ingredients (94.60%)
The Other Ingredients is basically sugar and water. So the only part to really be concerned about would be the 5.4% borax.
Maybe the question is best phrased as: would dumping borax on a tree hurt it?
