Termites – Notice anything unusual?

I was driving the other day and noticed this on numerous homes in one specific neighborhood. Well here is my take, the pretreat didn’t work. So why did the pretreat not work? Here are my clues on this one.

1. Wasn’t done at all.
2. Wasn’t the correct mixture.
3. Maybe somebody thought they did these homes, maybe not.
4. Maybe a chemical we thought would work in AZ and didn’t.
5. Wasn’t done at all, oops I said that again. Many of these homes had limited angle drilling and that leads me to think something is amiss, I’m not dropping names but in my opinion it’s a scary thing.
