How much borax do you add to a quart squirt bottle of water to use for insecticide? Anybody know? Thanks!

First question would be why use borax to begin with, though considered low toxic it is still a number of times more toxic than anything else you or an exterminator would use for insect control. It is a slow acting stomach poison, so it would take time to get the job done if you are fighting a current insect infestation. The borates can be effective by lightly dusting out of the way places of the home, but mainly as a preventative.
