When I got my hands on the HARRIS Boric Acid Roach Killer Powder with Lure, I was eager to put it to the test. Here's my in-depth review, drawing from my own experience and others at the Repellent Guide team.

First Impressions:

The product's packaging is robust and informative. The lure's addition intrigued me, given that many such products rely solely on the killing agent.

Test Setup:

To gauge the product's efficacy, I applied the powder:

  1. Behind my kitchen's refrigerator
  2. Along the baseboards in my living room
  3. In cracks and crevices in the basement where I've spotted roaches before

I also set up a controlled test area in my garage, placing the powder at the entrance to see if it would deter roaches from entering.


  • Barrier Creation: The product promises a barrier that roaches would have to crawl through. While setting it up, I observed that the powder's consistency was slightly heavier than expected, likely due to the lure.
  • Action Mechanism: Boric Acid interferes with the roach's digestive system, making it a lethal agent. The fact that it can transfer the effect to other roaches when the affected one returns to its colony is a notable feature. Within my testing period, I observed dead roaches within the promised 72 hours.
  • Versatility: It's clear that the product is designed for a range of environments, from homes and markets to ships and mobile homes.
  • Longevity: As long as it remains dry, the powder can continue its killing spree. I found this claim to be accurate over the weeks I observed.
  • Attraction: The lure is a distinguishing feature. While it does its job of attracting roaches, its weight affects the powder's 'puffiness' and distribution.
  • Safety: Being EPA registered and suitable for homes with people and pets is a significant advantage.

Team Feedback and Findings:

Drawing from Repellent Guide Team feedback and my own experiences:

  1. Effectiveness: There's a consensus on its efficacy. One member mentioned placing it around their home's exterior and inside their garage, which deterred bugs from entering. I had a similar positive experience.
  2. Consistency Issues: A point of contention was the powder's consistency. The lure, while effective in attracting roaches, made the powder denser than what many are used to. One member mentioned that it poured "like sugar," which I found accurate. This heaviness made it challenging to achieve the desired 'smoke-like' dusting effect.
  3. Pet Safety: The product's non-toxic nature for pets is appreciated, but caution is still advised. A team member avoided placing it where their dogs might sniff, which is a practice I'd also recommend.


The HARRIS Boric Acid Roach Killer Powder with Lure is undoubtedly an effective product with the added advantage of the lure. However, there's a trade-off in terms of its consistency. If you're looking for a roach deterrent that can be used in various settings and you're willing to adapt to its heavier-than-usual texture, this product is worth considering. Remember to always apply with caution, especially in homes with pets.
