Many houses are built with inherent weaknesses in their construction. This weakness allows undetected access to termites. Unless the homeowner has experience with many types of buildings, it is almost impossible to understand where to check.
Cracks in concrete slabs, wooden pegs through concrete slabs, high soil levels around buildings and many other conditions add to this difficulty. If you are looking for professional inspections in Texas then you can browse online.
Familiarity with a building can cause a homeowner to blaze. This can occur with the best termite inspectors when sent to the same property regularly. That certainly can happen to homeowners.
Homeowners tend to believe that they have greater knowledge about their castle than anyone else might and therefore they are better off checking it for termites. Out of curiosity about a building that has never been seen by people, often all kinds of problems arise that were not previously detected by the homeowner.
If you have to check your own home for termites, please do it together with a professional, and make sure you do as much research as possible before doing so.
Termites don't always need to build shelter tubes because they can successfully travel through landscaping and wood or other tree roots.
Termites can also make their canister of residence easily by using a small gap between the woods, e.g. sleeping or between brick walls where there are gaps e.g. Behind the engaged dock.
Some species of termites can nest in tree trunks, it is easy for these termites to dig the middle of the root of the tree and follow them for a long distance to appear without being detected several meters from where they started.
