Drilling & Injecting

Drilling concrete slabs and injecting chemical is one of the ways to protect a property from termites, and then there are obviously variations of those treatment methods depending on the type of construction and requirements of the treatment. However, there have to be a few specifications met to ensure it is done correctly. Here we will highlight a few for you to consider.

Hole Spacings! When holes are drilled to inject termiticide under a concrete slab to treat the footing of a wall, the holes cannot be more than 150mm from the wall. This home had holes exceeding 300mm. Needless to say, the original treatment failed …

Holes are often drilled around a perimeter to ensure a complete chemical barrier to prevent termites getting in.

Mould. A sure sign of high moisture.

High moisture is a major conducive condition to termite attack, and nothing says "hey there's lots of moisture here" better than fungus.  Mould is often seen growing in areas of persistent moisture. So it's not surprising that where here is mould, there are termites nearby. This is because the prevailing conditions required for both mould and termites are very similar. So if you see mould in your place, it might be time to get a termite inspection. It's also a good idea to do all you can to reduce the moisture (and mould!) in your home for health reasons.
