Insects That Can Damage Buildings

Posted on: June 23, 2025, in Blog

Insects can pose significant threats to the structural integrity of buildings, often causing damage that is both extensive and costly. Knowing which insects are responsible—and how to spot the signs—is key to protecting your property.

1. Subterranean Termites (White Ants)

These are among the most destructive insect species in South Africa. Living underground, subterranean termites infiltrate buildings through tiny cracks in foundations or walls. Once inside, they feed on wood like skirtings, door frames, windowsills, and roof timbers—often silently causing serious damage from the inside out, before you even know they are there.

Signs of Infestation:

  • Mud tunnels on walls or foundations
  • Hollow-sounding or visibly damaged wood
  • Accumulation of termite droppings

Prevention Tips:

  • Eliminate moisture around the building
  • Regularly inspect wooden structures
  • Ensure proper drainage near foundations

2. Drywood Termites (Woodborer Beetles)

Often referred to as woodborer beetles, these pests infest dry wood, targeting furniture, roof timbers, and wooden flooring. They tunnel into wood, leaving behind small holes and powdery frass (wood dust).

Signs of Infestation:

  • Tiny, round exit holes in wood
  • Fine wood dust beneath wooden items
  • Weakened, brittle, or hollow-sounding wood

Prevention Tips:

  • Keep wood dry and well-ventilated
  • Seal cracks to prevent access
  • Conduct regular inspections, especially in coastal areas

3. Ants

Certain ant species, particularly those that nest in wood, can weaken structural elements. They’re also known to tunnel through insulation and wiring, compounding the damage.

Signs of Infestation:

  • Trails of ants entering the building
  • Soft rustling in walls or woodwork
  • Piles of wood shavings or disturbed insulation

Prevention Tips:

  • Seal all cracks and gaps
  • Store food properly and clean up spills
  • Trim vegetation away from buildings

Protecting Your Property
Regular inspections and early intervention are crucial to preventing major damage caused by insects. If you suspect a problem, don’t wait—contact a professional pest control service.
