Step 1
Locate the source of the cockroach problem. This is usually in a warm, damp place like under the sink or refrigerator. Clean any spills or stray food particles before applying the boron. Make certain the application surface is completely dry. When boron becomes wet, it loses it's effectiveness.
-
Step 2
Create a barrier of boron around the perimeter of the area by sprinkling the powder in a continuous line. The area can be a single room or the entire exterior of the house or building.
-
Step 3
Watch for signs of the infestation decreasing. Boron is toxic to the cockroaches through absorption. This means the roaches will crawl through the barrier of boron several times before dying.
-
Step 4
Re-apply the boron as necessary when there are any signs of pests.
-
Step 5
Keep the area free from debris, trash and food substances on a regular basis. This will keep the infestation of any pest to a minimum.
