August once again marks the start of rodent season
An annual reminder that saves time and trouble in autumn for those who read it early enough.
The same process begins in mid-August every year: nights become colder, crops are harvested, the food supply disappears, and rodents move towards places that offer warmth and food. This is the most predictable process in the pest management calendar — and the one most routinely overlooked.
The difference between preparing in August and responding in October comes down to what you are dealing with. In August, isolated rodents are scouting for suitable premises. In October, an established population is already breeding in the warmth and has developed its own routes and nests.
The sequence remains the same year after year. First, seal entry routes: gaps under gates, utility penetrations, unscreened ventilation openings, and air vents. Then remove sources of shelter and food: weeds along walls, stacks of containers, clutter in break rooms, and exposed waste. Only then should bait stations be installed — first around the outside perimeter, then indoors along the walls.
The format should be matched to operating conditions. Wax blocks are suitable outdoors, in damp areas, and in utility pits: they do not become waterlogged and retain their shape through temperature fluctuations. Soft dough baits are generally used inside heated premises because they remain attractive even when other food is available. At grain facilities, grain bait is the logical choice: familiar to rodents in appearance and taste, it can compete with the surrounding grain.
Inspections must also be regular: every one to two weeks, with bait replenished and particular attention paid to points where consumption remains consistently high.
