If you see yellow powder in your wooden cupboards and drawers everyday, which comes back the very next day even if you clean it, then you most likely have a problem of borers.
Wood-boring insects such as Powder Post Beetles cause untold damage to furniture & other wooden articles. They are very destructive & reduce precious wood into dust. The powder or dust falling from the holes in the wood is the excreta of the borers and undigested cellulose of wood.
Wood Borers are controlled by injecting the insecticides in the holes with a syringe. Insecticide is also sprayed over wood. For Wood Borer Control a contract of three months is generally sufficient. After initial major treatment, we come on call, whenever you see powder falling again. In most cases, three months treatment is enough. If the infestation is not controlled by three months, it will be necessary to enter into one year contract.
