There are lots of reasons to use weatherized Niban Granular Bait, but have you tried prebaiting for emergent pests? You can even apply Niban in advance on snow, the company says. After a cold winter, it only takes only one warm day for forager ants to erupt by the hundreds at your customers’ homes, looking for food. If you prebait ahead of time, their meal is taken care of — and so are they! Ants take food back to the nest and share it, killing the entire colony and the queen. Niban solves your potential callback problem before it can even get started.
