How to Get Rid of Borer from Your House
Treatment of timbers to remove borer infestation is the same for whichever species is present.
1.Treat any bare wood with solvent based NO Borer Concentrate or NO Borer Ready to Use. Solvent based insecticides using turpentine or kerosene will penetrate deep into the timber and will kill larvae as they eat the wood. The insecticide also prevents adults laying eggs on the surface. In normal circumstances this will protect the wood for many years.
2.The solvents used to carry insecticide deep into the timbers will leave a solvent smell for some days. Ventilation will help to dissipate the odour.
In areas where the smell would be unacceptable there are water based options such as NO Borer Ready to Use Trigger Spray but these do not penetrate as deeply and will not give as good long term control.
3.Inject flight holes in painted, varnished or polished timbers with NO Borer Aerosol Injection Fluid. This comes supplied with a nozzle for fitting into the flight holes. The aerosol forces insecticide into the labyrinth created by the borer larva, killing any larva in the labyrinth or nearby. It also prevents adult beetles laying eggs in the flight hole.
4.During each flight season (October-May) set off NO Bugs Borafume borer bombs in roof voids and sub-floor areas. These knock down adult beetles that would lay eggs on the exposed timbers and give some protection to the surface of the timbers.
5.Borer prefer timber that has some moisture in it. Ensure that your sub-floor is dry and well ventilated. Check for plumbing leaks and unblock all air vents. Check for leaks in the roof and if you have old terracotta or concrete tiles. These can act like sponges soaking up water and increasing the relative humidity of roof voids. Check that tiles are well sealed with NO Leaks Masonry Sealer or NO Leaks Red Brick and Terracotta sealer to prevent moisture penetration. |
