IF you do not ever plan to sell your home, then yes DIY. However, I used to live in FL (for 19 years) and I saw a lot of termite problems (not in my home) in others homes. Some had "Professional" termite contracts and still got termites. The good news is that the bonds (which were a LOT more than 10K - low 6 digits, as I remember) covered some very expensive repairs. A friend spent about $15,000 of his own money doing repairs trying to move out of eastern central FL (he did the Sentricom DIY program). HO-1 policies do not cover termite damages. IMO I would spend the money and I would go with termodor, senticom (sp) is more of a hassel. When they do the WDO (Wood Destroying Organisms) inspection at time of sale, you will feel much better if you had professional servcie (with the repair bond).
