Susan from Kapolei, Hi writes
After the vial is cracked, is there supposed to be a liquid that spreads to the cloth? If not, and a rattling sound is heard while the disk is shaken (sounds dry), does it mean that it's ineffective? You mentioned that it has a shelf life of about 1 year. How would I know that I'm not provided an old batch upon ordering?
The Gentrol Point Source should have a visible liquid that spreads through the trap once activated. You should be able to see it go over the paper in the trap. If you are experiencing any issues, please let us know the lot number of the box that you received, and we will report this to the manufacturer and move forward with a solution for you.
