Treating The Exterior Walls To Guard Against Subterranean Termites

Posted on

The best way to eliminate a subterranean termite infestation is to treat the hive directly, but it is sometimes difficult to locate the hive. Termites reach your home by traveling through the soil and burrowing through wooden structures. Therefore, if you identify a subterranean termite infestation, you will need to treat the soil near the exterior walls of your home to prevent termites from entering your house.

Identifying Subterranean Termite Infestations

Because the type of termite infestation will affect the type of treatment you should use, first find out what types of termites are targeting your home. Subterranean termites first invade a building by sending winged insects called swarmers. To distinguish them from ants, look at the antennae. The termites have straight antennae.

You are most likely to encounter them in southern states. You may find termites in a nearby fence or woodpile, but this does not mean your home has become infested. Still, by discovering them, you will want to look for further evidence around your home of termite damage. Termite-damaged homes often have

  • Unexplained sawdust

  • Damaged wood, plaster, or siding

  • Peeling wallpaper

  • Cracks and tunnels that become visible in walls and floors

Treating the Exterior Walls

To prevent the termites from entering, treat the exterior walls of your home with insecticides to kill invading termites. Not only will this treatment stop new termites from arriving, but when your resident termites leave your home, they will also be killed.

Applying the Insecticide

Use a digging tool, such as a trench shovel, to dig a six-inch deep and wide trench. It should travel down the entire length of the exterior wall. Then, apply a non-repellent termite insecticide. Repellent termite insecticides will simply discourage termites from exiting your home and crossing the deadly barrier, while non-repellent insecticides are difficult for termites to detect and are deadly. Rather than killing termites outright, the foragers pick up these insecticides and bring them back to the colony where it is shared with the other termites.

The insecticides are liquids that are applied by following manufacturer's instructions. If applied correctly, the insecticide can continue to kill termites for about five years. After the application, fill the trench in and add more of the insecticide to the soil as you do so.

Hiring a Termite Control Specialist

You may be tempted to ignore the termite problem, given the work involved in treating it, but termites will cause damages that are much more expensive to repair than hiring a termite exterminator. If you do not want to treat the problem yourself, hire an exterminator. Oftentimes, it is difficult to know whether your home is infested until it is too late and only an expert can know for sure.
