Managers of food warehouses, food processing plants and other commercial buildings with substantial food storage can have frustrating experiences with mice and rats continually getting into the building. That may be an ongoing ordeal even though the managers have been following traditional pest-control measures. Professional pest control technicians know how those rodents get in and can help you put a stop to the problem.
Ineffective and Unsuitable Pest Control Practices
One measure that has historically been relied on, but often proves relatively useless, is to place metal traps at evenly spaced locations around the perimeter of the building. Unfortunately, not only do most of the traps stay empty, an employee has to spend time routinely checking all of them.
Poisoning rodents in a facility is generally prohibited. Any chance of cross-contamination could lead to disaster. In addition, poisoned mice and rats tend to crawl into walls of buildings, where they expire and exude a disgusting odor.
Even the issue of baiting traps is a complex one. Food processing facilities that guarantee no contamination from peanuts or other nuts, for instance, cannot use nut baits in traps.
Considering Where Rodents Get In
It may be a valiant effort to attempt to catch random rodents all around the building. However, focusing on key locations makes more sense.
Professional pest control services inspect the facility to find possible points of entry. Any small holes at the foundation level, for instance, should be filled to block rodents.
Some rodent entryways can't be permanently blocked off. The critters may come in at the loading dock, for instance. Mice sometimes take up residence in pallets and thus have an easy way into the facility. Without concentrated trapping in this area of the building, rodents can prove extremely difficult to control.
A more effective approach to pest control involves logging the trapping successes and gradually removing traps that never catch rodents. That way, employees don't waste time checking them. Adding more traps where rodents are a known problem is advisable. However, ask your third-party auditors whether this strategy is acceptable to them before taking action. They may require a certain minimum of evenly spaced traps. You can still add more traps in areas that show infestation even if you don't remove others.
With the assistance of professional service technicians, the food facility is better able to manage rodent problems. Having mice and rats get into the building isn't entirely unexpected. They are attracted to food, crafty about getting inside and can fit into tiny holes and crevices. Pest control must be ongoing.
