If you know exactly how to inspect for termites around your house, maybe DIY termite treatment is an option for you. But is it possible to purchase Termidor yourself? According to Termidor's official website, it states :

Termidor cannot be directly purchased or applied by homeowners. Only licensed pest control professionals who have taken Termidor Certification Training are authorized to purchase and apply Termidor.

But the truth is that you CAN purchase Termidor online without a problem. Even Amazon carries Termidor SC. Other online vendors say anyone can purchase and apply Termidor as long as it is used on their own property. But you have to be licensed if you are treating other peoples property.

There are states that doesn't allow Termidor to be used; AK, CT, NE, NY, SC, MA, IN Try an alternative if you live in one of these states. You might want to try Dominion's termiticide line. (Dominion termiticide is banned in AK, AS, HI, NY, PR as well)

Termidor is a great termiticide and it can be purchased by anyone. I really don't know why Termidor's official position is that only licensed professionals can use it, but make your own decision. I bet it has to do with legal & liability issues.
