whichever one you go for, make sure they offer free yearly, or semi-yearly inspection, with free or reduced pricing on retreatment if necessary, with their treatment packages, that way, a recurrence is prevented and treated as soon as evidence is shown.
Ehrlich is one of those companies, my parents had them treat our house for termites 6 years ago, and they send a postcard every six months to set up an appointment for them to come out and check to see if they’ve come back.
