Bora-Care can only be used on cut lumber/wood not any actual plant/tree. We would recommend to use Dominion 2L which can be applied directly where they are infesting in the stump and around/on the stump for carpenter ants. Be sure to treat around your home as well to prevent. Check out our Termite Guide for all the up to date tips on Termite prevention and control. We also have one for Carpenter ants here.
We do not advise to mix any waterproofing product, paint or sealant in the same tank mixture when applying BoraCare. A topcoat with a water-resistant finish such as paint, stain or water sealant is recommended within 6 weeks of the initial BoraCare application for longer performance. This can be done as soon as 48 hrs after the application provided the wood is compltely dry.
BoraCare is applied at 1:1 ratio for curative treatments and a 5:1 ratio for prevenative treatements.
