Harris Roach Tablets combine the proven effectiveness of Boric Acid with sugar, flour and a proprietary lure that creates a food that insects truly crave. It's not just roaches that love these tablets; ants, silverfish and waterbugs go for them as well. These tablets have been evaluated and listed by OMRI (Organics Material Review Institute), so you can be confident in using them around your home and in organic settings.
Harris Roach Tablets can remain effective for several years, if they are kept dry. If they get wet, you should consider replacing them. Do not apply insect spray over the tablets as this will also negatively affect their performance. For best results, it is recommended that you replace tablets yearly.
One box of roach tablets contains a minimum of 145 small tablets and can treat an entire house; just place them in those out-of-the-way spots that roaches like to hide and travel. Please read "Use Instructions" for additional suggestion/guideline on tablet placement. This product is sold by weight, not by volume. It is normal for some settling of contents to occur during transportation and handing. Complete instructions in both English and Spanish are on the label, which you can see under the MSDS tab.
