been using mark-it blue for about 5-6 years I have 5 acres with a lot of tumble weeds I ad added mark-it blue. Due to the cost of weed killer I started using mark-it blue it saves a lot of $$$ because I do not duplicate spraying the same weeds multiple times.

Helpful with herbicide application but hard to see on dark green foliage unless recommended amt is doubled. Even at 2x strength I will get alot of applications from one bottle. Accidentally knelt in full-strength blue dye; worried i would be 'tattoed' for a long time but several hours later nearly all showered off with only a little effort using soapy washcloth.

Yes, Monterey Mark-It Blue can be used when treating with Bora-Care for a termite treatment. Just be aware that the dye will also most likely soak into the wood as well.
