There are only a few ways to confirm a termite presence in your home. Inspecting the bases of your home’s foundation and any wooden structures they will eat away, start at the base of the wooden structures on top of your foundation. While checking the foundation you also should check for any mud structures or tubes. Termites do not like exposure to the weather or outdoor environments so they will always dwell in the soil whenever they can.
When they want to move from the ground to the wooden structures in your home they will build mud structures and tubes for them to move from back and forth. They need to move back and forth so that they can renew the moisture in their bodies. This is a critical weakness among termites. They need to go into the soil so that they can retain moisture in their bodies. By treating the soil you will effectively treat / immunize your home against termites for about five to ten years depending on the product you use. Termidor will protect your home for about ten years if you follow the directions and use it correctly.
It is recommended that you use a trenching shovel as opposed to any normal shovel; it will work better and make the work pass by faster. You may want to have some help because treating your whole home with the trench method is laborious for just one person to pursue. You will also need to pay close attention to other spots like any concrete slabs around your home. The soil under these slabs will also have to be treated. If you leave an area of soil untreated next to your home then the termites will be able to go through this ‘hole’ and continue to eat your home.
Normally with older homes the concrete slab will have moved away from your home about an inch (this is particularly telling with driveways and patio slabs). When there is a gap like this then you don’t have to drill through the concrete to reach the soil, the gap will act as a trench for the treatment.
