Harris Boric Acid Roach Powder

The powder includes a food-grade lure designed to entice roaches and other crawling insects out of their hiding spots. Once they are drawn to the powder and make contact with it, the boric acid begins to work on their system.

You can expect the formula to neutralize pests within 72 hours of contact. While it acts relatively quickly, keep in mind that it works best when applied in areas where insects are known to travel.

Yes, this product is EPA-registered for use in households with people and pets. However, you should still apply the powder in cracks, crevices, and areas that are generally inaccessible to children and animals, such as behind appliances or inside wall voids.

The powder provides long-lasting protection and remains effective for weeks after application. The most important factor is keeping the area dry; if the powder gets wet or damp, it will lose its potency and need to be reapplied.

In addition to roaches, this formula is effective against palmetto bugs, water bugs, and silverfish. It is designed to handle a variety of crawling insects commonly found in residential and commercial spaces.

For the best results, apply the powder in dry areas where pests hide or travel, such as behind refrigerators, under sinks, in wall voids, and along baseboards. It is ready to use straight from the container, making it easy to dust into tight cracks and crevices.
