Each box contains 15 ready-to-use sachets. There is no need to open them. For best results, use only 3-5 sachets at a time. Do not use all 15 sachets at once.
To use, simply remove the sachet from the box and dip it or wipe it with left over sauce, such as adobo after cooking or used cooking oil. Leave the sachet in the corners of the house that the rats frequent. Do not open the sachet, as the rats will eat through the packaging.
