Termidor has a delayed reaction so it gets brought back to a nest (good for termites, ants, etc.) Talspar kills soon after contact.
I don't have any issues with bugs.
I have never had good results with Ortho home defense and other store-bought stuff.

The quoted post above is excellent advice.
To add to it, also spray around all external light fixtures.
I also use Bifen from domyown(dot)com here:
Bifen IT | Bifenthrin 7.9% Insecticide | Fast, Free Shipping
These are all commercial level treatments. They are what you pay a lot of money for the hired guys to spray. They have a residual property - they keep acting long after sprayed.
Also they are effective against a lot of other bugs.
