Harris Roach Tablets

These tablets use 40% boric acid, which acts as a slow-acting stomach poison. Because the effect is delayed, roaches ingest the lure and carry the powder back to their colony, allowing the treatment to spread and eliminate the infestation at the source.

Place the tablets in concealed, dry areas where roaches travel but people and pets cannot reach. Ideal spots include behind appliances, inside drawer wells, under sinks, and within tight cracks or crevices.

While the tablets are odorless and easy to hide, they contain boric acid, which is toxic if ingested. You must place them in areas that are completely inaccessible to children and pets, such as behind heavy appliances or inside sealed cabinets.

While the tablets can remain active for up to two years if kept dry, we recommend replacing them every 12 months to ensure maximum effectiveness and potency.

For most rooms, you should use up to 12 tablets. Because they are designed to be placed in specific, targeted areas rather than scattered everywhere, a small number is usually sufficient for effective control.

No, moisture can degrade the tablets and reduce their effectiveness. It is critical to place them only in dry locations, away from water sources like leaky pipes or areas that are frequently mopped.
