I bought my first container of this a couple years ago and have been using it as a perimeter spray for the house. Each time I put it down, I end up with piles of dead roaches on the porch. VERY effective. I only put this down a couple times a year even though it's approved for every 21-dy intervals. It lasts a long time and works. Note that this seems to be the same active ingredient as Cyonara 9.7 which also has all 5-star reviews and comes in a bigger package. If you expect to apply every 21 days, it may be more cost effective that way.
