How to prevent solid wood furniture from getting borers?
Preventing borer infestation requires protection from the time of purchase and good daily maintenance habits.
Inspection at purchase
- Carefully check new furniture for holes and powder.
- Pay attention to the bottom, back, and joints — these areas are most prone to hiding borers.
- Smell for mustiness (damp wood is more susceptible to borers).
- Choose wood that has been kiln-dried (moisture content 8-12%).
Daily preventive measures
- Keep dry and ventilated
Borers survive and breed more readily in damp wood. Keep indoor areas ventilated and dry; leave 10-15 cm gaps between furniture bottoms and walls/floors to prevent moisture accumulation. Keep furniture away from moisture sources (bathrooms, kitchens, exterior walls). In southern humid seasons, use a dehumidifier.
- Regular cleaning
Regularly wipe furniture surfaces and backs with a dry cloth; do not let dust and debris accumulate in corners and crevices.
- Control indoor humidity
Aim to keep indoor humidity below 50%. Especially during humid seasons (southern rainy seasons, spring humidity), use air conditioning or a dehumidifier. Borers reproduce fastest at 20-30°C with humidity above 60%.
- Chemical prevention
If you live in a humid southern area, apply a small amount of dinotefuran-containing household insecticide to the back and underside of furniture (out of sight) as prevention; once dry, it forms a protective layer. The visible surfaces do not need spraying.
- Insect prevention for old furniture
When restoring or bringing in old furniture:
- Sand off old paint and check for borer damage.
- Treat any holes with injection and seal.
- Reapply varnish or wax to seal the wood surface.
Regular inspection
It is recommended to check furniture bottoms and backs twice a year, especially during spring and summer when borers are active. Treat promptly if powder or holes are found.
