Asked by Pih from United States06/25/2012QWestern drywall termites in framing of house treated with Boracare. Still alive after 3 days. To be expected?
We gave all framing 2 treatments of 50/50 boracare/water 3 days ago. Still finding live termites crawling on treated wood. How long does it take to kill them? Is it a safe bet to reapply insulation and siding yet, or should we give the wood another treatment first? Should we be concerned that the termites will spread to other areas like say the attic where we have not treated, while everything is open and exposed to elements? Should we treat the back side of the siding and the black fire barrier material as well?ABora-Care can take up to 90 days to completely penetrate through all of the wood to where all of the termites are. Bora-Care does not kill the termites by touch. The termites walking on the wood are not effected. Bora-Care kills the termites by ingestion. After the Bora-Care …
Read Full Answer »Bora-Care can take up to 90 days to completely penetrate through all of the wood to where all of the termites are. Bora-Care does not kill the termites by touch. The termites walking on the wood are not effected. Bora-Care kills the termites by ingestion. After the Bora-Care has moved through the wood, the termites that are still in the wood will die when they continue to eat and ingest the Bora-Care with the wood. You should treat all exposed sides of the wood that you can get to. One treatment is normally enough unless the wood you are treating is more than 8 inches thick. The termites will not spread easily to other areas so that is not a concern. -

Asked by Paul from Dade, Florida09/19/2011QCan I apply Boracare with a paint brush? What should I do with left over solution? Can it be stored?A

A 1:5 mixture ratio can remain stable for up to 30 days. You should do your best to only mix enough solution for the job you are doing that day to prevent having to discard any solution. Any unused solution can be dumped out right up against the foundation of the structure taking care not to get it on plants. -

Asked by Chris from Arlington, Va06/05/2018QHow many dry days in a row do you need to have before applying Boracare to a cedar fence? And how long does it take to dry?
Also, if I apply this along the bottom three feet of my fence (sufficient for a termite barrier), will the fence stain evenly?AWood just needs to be dry before applying Bora-Care. It can take up to 48 hours for it to dry after application. It should dry clear when mixed as directed and would not affect stain once dry.Â
