Termites have a natural enemy that finds them under ground and will kill them. No it is not an anteater. Not in Texas. But we do have loads of them.
It's FIRE ANTS!!!
Fire ants will attack and kill termites who have no defense against them. I once had a client with a house in La Porte, Texas infested with Formosan Termites. The house was destroyed by the Formosans so much so that the City of La Porte condemned the house. All of the sheetrock had been removed and every stud in that house had some form of extensive termite damage. You could stick you finger through some studs.
I used to go to the house and break open a tube on this one corner of the house and observe the Formosan soldiers vigelently attack and rebuild the shelter tube. One day in the summer, I went out there and broke open the tube and nothing. Jeff Tucker, a Board Certified Entomologist in Houston pointed out that there was a fire ant mound only a foot away and that the ants had killed off the termites trying to get in the house.
So what Orkin could not stop - the Formosan infestation - mother nature took care of.
