Rodent control is often an unsettling subject – no one feels comfortable in the presence of unwelcome pests. In the case of restaurants and food processing businesses, however, the problem of rodent control goes beyond personal comfort and into significant public image and financial loss. A restaurant’s success is determined by its public reputation, and nothing destroys a hard-earned reputation faster than a rodent scurrying across a room where food is served and/or prepared.
Rodents, along with flies and cockroaches, are the bane of any food service operation, as they are directly and/or indirectly the cause of:
Tough public health guidelines against rodents exist for good reason, and the reason is that rodents carry numerous pathogens and bacteria that cause life-threatening diseases in humans and other animals. Through their droppings, rodents can spread Salmonella, asthma, murine typhus, rat-bite fever, infectious jaundice, and the notorious Hantavirus. In 24 hours, a single mouse can urinate thousands of times in micro-droplets and produce up to 75 droppings. In 6 months, a pair of mice can eat 4 pounds of food and contaminate 10 times more. In one year, rodents alter enough food to feed 200 million people.
Many restaurant owners and managers decide to take matters into their own hands when it comes to rodent control on their premises. Their attempt often fails, for two reasons:
1. Commercial DIY pest control is difficult and ineffective. Most common insecticides used for homes and businesses are not always labeled for use in food serving areas due to possible contamination of food and utensils. Even if a certain combination of pest control methods seems to work, it will most likely solve only the current infestation instead of addressing the factors that allow pests inside in the first place.
2. There are several regulations and limitations for pest control in any commercial food handling area. In Canada, strict regulations are in place to ensure that the application of pesticide insecticides and rodenticide residues don’t contaminate the food, food preparation equipment, serving areas, etc.
Although rodenticides might have worked to control rodents in food establishments two decades ago, the science of rodent control has evolved significantly to provide higher efficacy and improved safety at a lower cost. Today, controlling rodents effectively over the long term can be achieved with the implementation of Integrated Pest Management (IPM), an approach that includes monitoring, exclusion, sanitation, and – only as a last resort – the application of rodenticides. Regardless of the size and extent of an infestation, a proactive combination between exclusion and sanitation is the only proven solution for long-term relief from rodents.
Essentially, IPM’s exclusion tactics involve the elimination of all access points pests use to gain access into a building (cracks, crevices, etc.). Rats can squeeze through an opening as small as a dime, which means entry points are not hard to find. Common entry points for rodents include exterior doors, loading dock doors, air vents, and along water, electrical, sewer, and HVAC lines. Holes in the foundation or loose roof tiles can also serve as access points for the pests.
The best exclusion practices for rodent control in a restaurant include:
Maintaining a high level of sanitation that eliminates food waste entirely is another important goal of IPM, which includes:
For any food establishment owner, protecting the restaurant reputation is the number 1 priority, and the impact of a rodent infestation can be devastating. Loss of reputation, revenue, time, money, and peace of mind that would normally accompany a rodent infestation are the reason why IPM practices are critical to the long life and success of any restaurant and food establishment. Working closely with a pest control professional in your area is a great way to form long-term practices and procedures that can help you keep your restaurant clean and your customers satisfied.
