How can I get rid of ants in my flower bed without killing the plants?

Make Sweet Traps

Another natural way to get rid of ants from your flower beds is to surround them with sticky traps made from items in your kitchen. Ants are attracted to anything sweet, so fill several glass jars with honey, maple syrup or a sugar syrup made from 1 part sugar to 1 part water and place them around your flower beds. The ants will be attracted to the sugary sweet liquids, crawl into the jars and drown. You'll need to throw away the contents of the trap and refill them weekly if the problem persists. found on: http://homeguides.sfgate.com/rid-ants-flower-beds-40429.html

apply food grade diatomaceous earth

great solution I used and this works wonders .

1 cup water 1 tablespoon brorex 2 tablespoons of sugar melt in small pot to desolve .

Soak a sponge in the solution and place where you see ants . The ants will bite and take it back to the nest. I also made extra and poured on Ant hills in the yard . Got rid of all my carpenter ants.

Sprinkle corn meal around.

Cinnamon

I experimented......I tried Ant and hornet spray......I used clorox cleanup and a household degreaser.....(.can't think of the name)...I'll get back to ya. These all worked FINE. Ants be gone.

packaged cornbread mix that says it is sweetened and put it where they are coming in if you can find it. They will take it to the mound, everyone will eat it and die, they can't digest the cornmeal, but will take it because it is sweetened. Little goes a long way.

Sprinkle brewed coffee grounds on the ground.

Either food grade diatomaceous earth or Jiffy cornmeal mix right out of the box.
