How to Detect, Treat, & Eliminate Termites That Are Living Inside Your Walls…
Step One – Confirm the Infestation
Before treating, make sure you’re actually dealing with termites.
Signs of wall infestations include…
- Hollow-sounding wood
- Small pinholes or cracks in drywall
- Faint clicking or tapping noises
- Buckling paint or wallpaper
- Mud tubes or visible droppings (frass)
If you’re unsure, consider getting a professional termite inspection to confirm & locate the infestation.
Step Two – Choose the Right Treatment
Professional Termite Treatment (Most Effective)
Hiring a licensed pest control company is the safest and fastest way to kill termites in your walls.
They may use…
- Foam termiticides – Injected into walls to fill voids and reach deep into wood.
- Dust treatments – Applied through small drilled holes to kill termites on contact.
- Bait systems – Installed around your home to eliminate the colony over time.
DIY Termite Foam or Spray
For small infestations, you can purchase termite foam or spray from a hardware store. These products expand inside the wall cavity and kill termites where they nest.
- Look for products labeled for indoor wall treatment
- Follow safety instructions carefully
- Drill small holes into the drywall to apply product directly into affected areas
Orange Oil or Boric Acid (Natural DIY Options)
- Orange oil contains d-limonene, which can kill termites on contact
- Boric acid is a common termite poison and can be dusted into wall voids
Natural methods may not eliminate the entire colony, especially if the infestation is severe.
Step Three – Seal & Monitor
Once treatment is applied…
- Seal up drilled holes with wood filler or wall patching compound
- Keep monitoring for new signs of activity
- Schedule follow-up inspections to ensure the termites are gone
