In many areas of the Northeast and Mid-Atlantic, wood destroying insect infestation is common. Heavily wooded areas provide ample oppty for these insects, including termites, carpenter ants, etc. I have commonly seen great homes have 'termite' problems. Even if you are lucky enough to buy a home that has not had termites, you should have your home checked regularly once you own it.
So, no, don't axe a property off your list because it had termites and has been treated. But, still, by all means, have another inspection to know the current status. And, have both the termite inspector and your general inspector look for any damage the prior infestation may have caused. Are there any repairs to the structure that need to be made as a result of the infestation? If the termites were there for a while before being treated, there might be some needed work to fix their damage. If that damage is minor, then ask for it to be repaired by the seller. If that damage was substantial, get a clear understanding from the inspectors what repairs will entail and make sure you are comfortable.
The mere presence of prior termites should not be a reason to steer clear. Even minor structure damage is not a red flag to steer clear. Be guided by the advice of your inpsectors. Ask lots of questions so you feel comfortable with your decisons.
