Why are the ants not taking the Nippon Liquid bait?
This problem, although not a common one, is not unknown and although we have been unable to replicate this, we are aware that ants from a particular nest may not show any interest in a tube from a particular batch. This may be due to the natural variation in the natural honey and sugar components of the bait. In such cases, we have found that a replacement tube solves the problem.
