Borer Basher™ is a semi-permanent preventative maintenance measure for controlling borer. When applied correctly it will last 10 to 15 years and in many cases much longer.  After treating borer since 2012 we have not had a recall back to a customer house.  We recommend rechecking the timber for borer every 10 years or so. It is possible that you will not need to retreat in the future.

We provide a service for spraying exposed wood in your home or we sell Borer Basher™ in three convenient sizes so you can do it yourself. The product is great to work with and comes in a water soluble powder. There is no lingering odour or fire risk and only minimal protective gear is required when applying the product.
