Borates - powdered/liquid
Borate wood preservatives have successfully been used to protect wood from attacks by wood-boring insects and decay-causing fungi for over forty years. This includes... log homes, frame houses, historic boats and other wooden artifacts.
Borates are a naturally occurring mineral salt mined in California. Borates work by eliminating wood as a food source or harborage for termites, carpenter ants, wood-destroying beetles and decay fungi. The wood becomes nonviable to them; therefore, the pests don't feed on the affected wood. If borates are consumed, they kill the microorganisms that produce enzymes in the insect's stomach, the insect can't absorb nutrients and it will starve to death.
Powdered borates...such as Timbor and Penetreat are considered 'Preventative', while liquids such as Bora-Care, Shell Guard and Shell Guard RTU (Ready to Use), are Remedial...that is where you have an existing problem.
NOTE: All powdered Borates are pretty much the same item with a different label...that is to say they all come out of the same hole in the ground. Thus coverage rates may vary with the Brand...however that is simply a difference of opinion on coverage rates between the competiting distributors.
