Ant Problem Remedy

I have this problem of managing ants around my house. I usually have pesticides on their way. But I found out that these solution is quite expensive and temporary. After a few hours of spraying, their comes again these ants marching.
So I read some articles on ant problems in the house and found these simple solutions that usually found in your house, not expensive. So what's the effective solution I used: talc (baby powder) and salt.
Sprinkle baby powder on their way. These talc discourages the ants. So they will not pass on that way. If baby powder is not available, try also salt. Sprinkle salts in their way, usually in your windows or doors. This will avoid ants from going back.
I also found out that killing ants will encourage other ants to go on that place because some odor on the dead ants will attract other ants.
You can also used vinegar with water (50/50) and spray the liquid on their way or to their colony.
