Avon's Skin So Soft is still working. The ants have not returned, however it doesn't seem to effect palmetto bugs (giant roaches very common here in Florida).

I have a screen enclosed patio in the front of my house, which it seems, is undefendable against these creepy invaders. I sprayed some Skin So Soft around the inner door sill, but the bugs seem to ignore it and continue to enter the house.

No ants though!
