Identify a Termite Infestation

You may be able to determine if you have a termite infestation by identifying swarming behavior, finding mud tunnels, and by examining damaged wood. Inspect the tunnels by using a pocketknife to break them open. Even if the tunnels are empty, you may still have a termite infestation. Inspect damaged wood by probing the wood with a pocketknife. The presence of mud tunnels or dried pieces of soil underneath the wood’s surface are signs of an infestation. Make sure to call a professional once you have determined that your house is infested with termites.

Steps

Identifying Swarming Behavior

  1. Look for swarming near lights. This is because light attracts flying termites, especially during the night. Also look for swarming near windows and doors. If you see a large congregation of termites in the air, then the termites are exhibiting swarming behavior. Swarming can occur during the day or night.[1]
    • Swarming generally occurs in the spring months, i.e., March, April, May, and June.
    • If you happen to see a termite fly out from under your porch, patio, or foundation, then this is a sure sign of an infestation.
  2. Observe piles of wings. Termites will shed their wings when they enter the next stage of their development. This usually occurs after the swarming period. In an infested home, you can often find piles of wings that have been shed by flying termites.[2]
    • Shed wings look similar to tiny fish scales.
  3. Look for piles of feces. Also called frass, termite droppings are ridged and small. They look like small, wood colored pellets. Oftentimes, you can find piles of feces near the openings of tunnels, as well as where they have eaten or nested.[2]
    • Sweep up the feces and dispose of it. Check the spot daily to see if more fecal pellets appear. If they do, then this is a sure sign that you have an infestation.

Finding Tunnels

  1. Look for working tunnels. In an infested home, you will be able to find mud-like tunnels extending from the ground, up your concrete or stone foundation and to a wooden structure. These tunnels are usually the size of a pen, but they can also be slightly larger or smaller.[1]
    • You may also be able to find tunnels on your floor joists, sill plates, support piers, and slabs, for example.
  2. Identify exploratory and drop tunnels. Exploratory or migratory tunnels can be found rising up from the soil but do not connect to wooden structures. Additionally, in an infested home, you can find drop tubes extending from a wooden structure back to the soil.[1]
  3. Break the tunnels open. When you identify mud tunnels, use a pocketknife to break open the tubes. If the tubes are active, you may be able to see worker termites. Worker termites are small and appear white or translucent. However, the absence of these termites does not mean that you do not have an infestation.[1]
    • If the tunnel is rebuilt after a few days, then this is a sure sign that you have an infestation.

Observing the Wood in Your Home

  1. Look for swollen ceilings, floors, and walls. These areas may also appear to have water damage. This is due to the hollowing out of your wooden structures, which is caused by the termites’ excavations.[3]
    • A mold or mildew-like odor may accompany a termite infestation.
  2. Observe holes in wooden structures. Tiny holes in wooden structures like walls and furniture are also signs of a termite infestation. Examine the holes. If you can identify pieces of soil around the edges of these holes, then you are dealing with an infestation.[1]
    • Buckling paint and/or cracked wood are also signs of a termite infestation.
  3. Tap damaged wood with a hammer. If you hear a dull thud, then your wooden structures have been hollowed out. Pick the surface of the wood with a pocketknife. See if you can find tunnels or pieces of dried soil or mud inside the damaged wood.[1]
    • These are signs of a termite infestation.
  4. Check your basement. Use a flashlight to examine wood construction in your basement, focusing on the areas where concrete connects with wood. Also examine the wood under your porch, wooden window frames and sills, joists, and supporting piers and posts.[1]
    • Make sure to examine both the interior and exterior parts of your foundation.
  5. Contact a professional. If you have determined that your home is infested with termites, then you need to contact a professional. A professional will examine your house, confirm that you have an infestation, and advise you on what steps to take next.[4]
    • Most do-it-yourself kits are not very effective at eliminating termite infestations.

Tips

  • Termites have a straight body (no visible waistline), straight antennae, and the length of each wing is the same size. On the other hand, flying ants have bent antennae, a visible waistline, and their front wings are significantly longer than their back wings.[5]
