Is product X better than product Y?
Apart from the things that look too-good-to-be-true, like weird electronic repellers, just about any termite product you're offered that has some sort of government approval or label is capable of doing the job. Trouble is that each product has situations that suit its use and usually also some situations where it isn't the best choice.
So how do you know which product to use? The easiest way is to ask your technician. For termites, nothing beats local knowledge. Your climate, your species and the way houses are locally built all have a major impact on what's the best management option. So, you can spend a lot of time researching all the options or you can spend a bit of time getting a background and then ask your tech.
Don't just look at which works best and is cheapest. Look at safety and environmental toxicity as well.
It is so easy to make mistakes and think you have control when you don't, so as you explore the options, just remember "Don't do this at home". Termites are nearly always not a DIY project.
