Injection Treatment for Wood Borers: Step-by-Step

Injection treatment is one of the most common professional methods for wood borers. It delivers treatment into the tunnels where larvae live.

The short answer

In injection treatment, a professional drills or uses existing exit holes and injects a wood-borer treatment into them, then treats surrounding surfaces. It reaches deeper than surface sprays and suits furniture, doors and frames. The process involves inspection, preparation, injection, surface treatment and follow-up. Keep children and pets away, ventilate, and allow drying time. Repair and refinish afterwards.

Step-by-step

1. Inspection to identify the borer and the extent of damage.
2. Preparation: moving and covering items, cleaning powder.
3. Injection into holes and, where needed, drilled access points.
4. Surface treatment of all accessible faces and joints.
5. Drying and ventilation time.
6. Repair, filling and re-polishing.
7. Follow-up inspection for new activity.

Why it works better than sprays

• Reaches larvae inside tunnels.
• Targets the infestation, not just the surface.
• Suitable for doors, frames and furniture.

Safety

• Keep children, pets and food away during treatment.
• Ventilate the area and follow drying advice.
• Do not use treated furniture for sleeping or eating until advised.

Limits

• Cannot reach every tunnel in very dense or heavily damaged wood.
• Does not repair damage.
• May need repeat visits.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
