Niban’s rain resistant granular bait means we can often schedule exterior treatments without fearing every passing shower will force an immediate return visit.

Niban is formulated to resist light to moderate rainfall, so apply it to dry surfaces or under cover when possible and the particles will adhere long enough to maintain effectiveness. Spread granular bait in thin, continuous bands along ant trails, foundation lines, and near voids, because concentration without clumping improves acceptance and reduces non target loss. Use a hand spreader or scoop to control placement and avoid burying granules under mulch where water run off can move them; placement in protected microhabitats such as under eaves, inside cracks, or along the soil line increases persistence. Check the label for required retreatment intervals and permissible application rates and follow those precisely; label directions also define conditions for reapplication after washout. Communicate to customers that light rain rarely necessitates an immediate reapplication, but heavy downpours can displace granules so plan a follow up inspection after extended wet weather. For monitoring, mark treated zones with chalk or removable flags and inspect for residual granules and bait acceptance by target pests before deciding to reapply.

The most common mistake is applying bait to saturated surfaces which causes clumping and reduces acceptance, so let surfaces dry briefly or choose protected placement. Another issue is overapplication in a single spot which invites non target movement or wash off, so spread thin bands and avoid piles. A frequent communication error is telling customers bait provides instantaneous control; clarify that rain resistant bait maintains availability but kills require pest activity and may take several days to weeks so monitor and only reapply after severe washout per label.
