  • Where Found: Inside walls, attics, hollow doors, and water-damaged wood 
  • Evidence: Sawdust piles, rustling sounds in walls, large black ants indoors 
  • Behavior: Do not eat wood but excavate it to build nests, especially near moisture 
  • Inspection Tip: Tap wood surfaces—hollow-sounding wood may indicate internal galleries

What to Look For

Signs of Wood-Destroying Insects

These observations can help guide an inspection, but they do not establish the species, age of damage or whether activity is current.

  • Piles of sawdust (frass) near wooden structures 
  • Tapping sounds or faint rustling inside walls 
  • Small, round exit holes in trim, baseboards, or beams 
  • Swarming insects inside or around your home in spring 
  • Discarded wings on windowsills or near doors 
  • Blistering paint or soft wood under slight pressure 
  • Mud tubes climbing up foundation walls 

Have unexplained wood damage assessed. An insect inspection and a building repair assessment address different questions.

Stop Damage Before It Starts

How to Prevent Wood-Destroying Insects in Missouri

Preventing infestations starts with moisture control, routine maintenance, and professional inspections. 

  • Keep gutters clear and direct drainage away from the foundation.
  • Address leaks and have damaged wood assessed for repair.
  • Choose appropriate materials and finishes for outdoor projects.
  • Store firewood away from structures.
  • Maintain gaps and openings around utility lines.
    • Discuss inspection frequency and any treatment recommendations for your property.

Regular monitoring is key to protecting your home’s integrity.

FAQs About Wood-Destroying Insects

Do carpenter ants and termites affect wood in the same way?
No. Carpenter ants excavate nesting galleries, while termites feed on wood. See the MU Extension carpenter ant guide and subterranean termite guide.

Can I tell whether damage is active just by looking?
Appearance alone is not enough. An inspection can assess insect evidence and whether further monitoring is needed.

Does every problem require the same treatment?
No. Recommendations depend on the insect, affected materials, activity and property conditions.

Will pest treatment repair damaged wood?
Pest service and structural repairs are separate. Have a qualified repair professional assess damaged building materials.
