Wood Borer Injection Treatment

A Targeted & Non-Invasive Solution
How our injection treatment works.
Verminator offers a professional wood borer injection treatment service that is effective, safe, and highly targeted. This method is ideal for treating infested structural timbers like roof beams, floor joists, and bearers without the need for extensive spraying.
The Process: Precision & Power
- Inspection: Identifying active borer holes and assessing the integrity of the timber.
- Drilling: We drill small, discreet injection holes into the wood at approximately 300mm intervals, to a depth that ensures full penetration.
- Injection: Using a specialized injection gun, we apply a concentrated, glycol-based wood borer treatment directly into the timber. The treatment is injected until the wood is saturated, indicated by seepage from the holes.
- Sealing: The injection holes are then sealed with a suitable sealant, leaving a clean, professional finish.
The wood absorbs the treatment, which kills borer larvae and eggs on contact. Crucially, the treatment also has a long-lasting residual effect, continuing to protect the wood from future infestations. Dead wood borers may emerge from the wood in the days following the treatment; this is a normal sign that the treatment is working.
No-Guarantee Spray Service for Attics
Please note that while we can provide a preventative broad-spectrum barrier spray for brandering inside an attic or roof space, this specific service does not carry a guarantee. This is due to the nature of thatched roofs and other materials that are difficult to treat with 100% certainty. The spray acts as a deterrent but cannot be guaranteed in the same way as our injection treatment.
Our Guarantee: 2-Year Warranty (on injection treatment)
