SOB. I've been spending a lot of money on different sprays to get rid of ants (There is construction going on nearby and the ants have invaded two of our buildings).
This morning I ran out so I made a 10% solution of bleach water and sprayed an area that is a chronic problem. I let it dry and so far, no more ants. I know the bleach knocks out their scent trail, but I didn't think it would be this effective.
Goll-ee Mr Science!
