I have been reading through the posts and and I am thinking that you can use regular boric acid in the place of Borax/MA. My question is this.... They have the bottles of Boric Acid powder used to kill bugs at my local Dollar Store. They have the pointy top on them for application that resemble ketchup and mustard bottles. It says it is 100% Boric Acid on the contents part of the label. They don't carry Borax. Is this a reasonable substitute and if so, how exactly should I use it? Also, would the amounts needed correspond with the amounts recommended by the pool calculator of Borax? Thanks for any help
