Can you manually convert it into a finer powder, to make it more effective against roaches?

YES... WHAT I DO IS USE THE BLENDER. I PUT ABOUT 10 OUNCES. OR A CUP. BLEND @ HIGH SPEED FOR 2 OR 3 MIN. AND IT BECOMES POWDER. EMPTY BLENDER. AND REPEAT. AFTER WASH BLENDER. IF IS NOT IN POWDER IT WILL NOT WORK AGAIN ROACHES, BECAUSE IT WILL NOT STICK TO THEN...

Can you use this in your carpet for fleas

Try dusting the carpet sparingly - leave for 48 hrs - vacuum the carpet thoroughly and re-dust and leave for 36-48 hours and vacuum thoroughly. After dusting the carpet you do not necessarily need to vacate the house - simply do not allow pets on the carpet however no harm would come to them if they are exposed to boric acid granular powered.

I received my package of boric acid from florida labs 3/2017. there is no expiration date or lot # on the bag. does this boric acid powder expire?

It will not expire. It will clump up in a high humidity environment like Arkansas. Seal it in double plastic bags.
