I wonder why Ants like this so Much?

Ants like getting into my things and I have to go smash and punch and kill them so why do you think I have so many ants? I mean this is getting kind of bad and then I will have an anthill in my garden. Oh my gosh this is bad! I water them and every time they come biting me, then I give the ant repellent and I might harm my flowers! What do you think I should do?
