Controlling Borer In Your Home19 Jan 2021

The threat of borer can have a disastrous effect on the condition (and ultimately the value of your property) when it comes time to sell.

If selling your property is on the cards and you're aware that parts of your home have borer, you need to start looking at prevention as soon as possible. Otherwise, you could face a hefty price tag to get borer affected areas of your property fixed (or have the borer affect the potential sell price of your property).

What is Borer?

While there are 7 species of wood-boring insect in New Zealand that can attack the timbers of your home, the most common of these is the house borer.

Adult females lay up to 100 eggs on bare timber or in old flight holes. The eggs hatch after 4-5 weeks and the larvae bore through the wood. The larvae can survive for up to 4 years and then pupate in a chamber near the surface. Finally, the adult exits the wood by eating its way to the surface creating a 'flight hole'. It mates and begins the life cycle over again. The flight holes are approximately 2mm in diameter for Common Borer and 3-4mm for Native Borer.

How Can I Best Treat Borer?

Professional pest control services are your best bet here, however, there are also some home control methods that you can use if the problem isn't widespread.

Kiwicare is a great choice and they have a product to treat bare wood called, NO Borer fluid. Using this product, you'll get right into the timber surfaces and kill the borer while also preventing adults to lay more eggs. Using a product like NO Borer fluid should help protect your home and it's surface for many years.

You can also try to inject the borer flight holes with Kiwicare 'NO Borer Injection fluid'. This differs from the fluid as you apply it from an aerosol can with a nozzle that fits directly in the flight holes. Again, this option will also help stop the adults from laying eggs.

Borer Bombs are recommended to set off between May - October. You simply use the bombs in your subfloor or roof cavity areas of your home, and the bomb will give protection to your timber surfaces. KiwiCare also has a Borer Bomb product called  NO Borer Borafume.

Finally, make sure that your home is dry. Borer loves timber that has moisture in it, so check your subfloor and roof cavities for moisture and look out for any plumbing leaks.

Prevention of Borer is the key. It'll not only be easy on your wallet now, but we'll ensure that your home is in better condition when it comes to selling.
