First, if there is sticky stuff, the ants could be farming aphids that produce it. Ants are quite industrious - the issues are while the aphids produce honey dew for the ants, the aphids are sucking juices out of your plants and buds and spreading disease.
One of the best ways I find when having questions about products is to go the mfg website first and then find on Amazon and look at reviews. Thus at the website, I checked the Orange Guard for Ornamentals.
It said:
“Orange Guard Ornamental Plants Concentrate gallon size is OMRI listed (Organic Materials Review Institute) as allowed for use in organic production. Diluted 4 parts water 1 part Orange Guard Ornamental Plants Concentrate is nearly 100% effective against a broad range of bugs including Adelgids (wooly aphids), aphids, lace bugs, leaf hoppers, scale insects, mealy bugs, mites, plant hoppers and white flies.At a 6 parts water 1 part OG dilution still over 90% effective. Best to use maximum dilution that is still effective, avoid treating in the heat of the day, avoid open blooms and absolute new growth. Does not repel honeybees, if not sprayed directly the bees can still work the flowers without harm.”
(My Comment - I would use at 6 to 1 solution or even go to 8 or 10 to1 solution. You can always increase the mix if you need to but you can’t go back. In fact, you can call them at the number below or email and ask about testing with orchids as they are much different from other plants whose roots are in soil. The active ingredient is a powerful solvent even though it is below 6%. You might - use something like Physan 20 which isn’t a pesticide but is used on orchids from leaves to roots (follow directions for weak solution too) but I think it would make ants in the soil unhappy (someone mention using dish soap - most regular dish-soaps today have to many chemicals, ammonias, scents, etc for me to trust on my roots). Then either spray the plant with the physan 20 all over or cover your roots and spray the plant with the Orange Guard at a very dilute solution. I would only spray one..the one you can replace the easiest and dislike the most. Let dry completely before exposure to sun. And as someone mentioned - do outside where the ants can run as they most likely will if not killed.)
The mfg goes on to further say -

I will let you look at the Fire Ant and any amazon reviews. The ones I have seen look good - I’m ordering some myself as I have used the active ingredient in cleaning products, strippers, and house sprays and liked it. Of course for stripping - it is much stronger. But I want to use on my porch under mats and around doorway to discourage spiders and earwigs
Good luck.
