Customer reviews
You will not regret buying this powder!!!!
We had a major fly issue in our bathroom for months and we had no idea how to resolve it as they were reproducing through rotting, damp wood. Luckily, we stumbled across this product after a Google search and it was the last straw before considering ripping the whole bathroom out. Aren't we glad we found this powder!! Incredibly easy to use (doesn't just spill out, it has a little hole for precise aim/application), a generous tube as well for the price and you don't need to use much when using it so we have loads leftover. Within a couple of days, all the flies were dead & they haven't returned since! We were able to hoover up all the recently deceased and apply another fresh coat of powder just to be safe. This stuff is an absolute lifesaver and has honestly stopped me from tearing my hair out every day! Do not hesitate to invest in this if you need it as it is literally a miracle!!
