You can find Harris Roach tablets on Amazon, Home Depot, etc. They’re nothing more than Boric Acid and bait. Rumor has it that the bait is simply powdered sugar. Regardless, they work. I used to see one Palmetto Bug every two days and after randomly throwing tablets all around the apartment, I haven’t seen any for the past two weeks. My roach motels have also caught none. I also used Diatomaceous Earth so my success may a combination of both methods. The tablets were easier to apply because I literally just threw them randomly around the apartment, . on top of shelves, under appliances and furniture, near pipes, plants, etc. And unlike the DE, boric acid works fine when wet. A $ box contains about 40 tablets and I’ve only used about 20.
Another early double-blind, placebo-controlled study of 320mg Permixon® daily found significant improvement in many symptoms of BPH over placebo.  A later retrospective study in men with urinary symptoms caused by BPH (no prostatic cancer and PSA less than 10ng/mL) given 320mg saw palmetto (Permixon®) for six months confirmed this.  It found an improvement in urinary symptoms when saw palmetto was used alone as well as when used alongside an alpha-blocker, although saw palmetto alone showed better responses on mean void volume and intermittence in urinary flow while combination therapy had a more rapid improvement in maximum flow.
