### ⭐⭐⭐⭐ Works
*by D***A on May 31, 2026*

Worked! No funky smell & the irritating little monsters were gone within days. I had previously tried traps, blocking the drains & using baking soda & vinegar cleanses to no avail. I think this stuff is ridiculously expensive, but as a last resort I can say it works.
