G'day SUE .. I suggested using Borax and salt a year ago and found that it helped me .
But NOW I use the BORACIC -( BORIC ) ACID . You may have mistaken Borax for the BORACIC acid in my recent blog re. the bath...just thought I'd let you know.
The BORACIC ACID is a natural insecticide and I know would help knock off your "Bug " problem . Don't know where you find the stuff in America . I buy mine fron E-bay Australia. You might find it at a pest control shop...make sure that it is 99.9% Boric acid.
If / when you have success with it please let others know.
You might want to review my recent blog on how to use it.
Perhaps also you may want to dissolve some and put it in a squirt bottle and spray you place.
