It's sticky stuff that the bugs can't cross. You do have to prune any
branches that touch a fence, wall or anyplace the ants can crawl up to
access the tree that way.

I've not seen the AntPro system before.

I want to keep ants off my Moro Blood Orange tree because they keep
transporting aphids on to it and the aphids damage the tree. I used
to use Combat bait granules but I can not find it any more. Then I
used Zep ant bait trays which I liked because they are transparent
and I could see when they were empty but I think they were
discontinued.

What is the best system for controlling ants that is still
available? I found this on the web:

Does anyone know if it is any good? Thank you in advance for all
replies.
