The house mouse is the most common threat to the food industry. This versatile creature can squeeze or gnaw its way through a hole the size of a dime, and quietly spread feces and urine in every inch of a warehouse. House mice, Norway rats, and roof rats eat and contaminate food sources, chew through boxes and wiring, and have 20 to 35 offspring per year. When you inspect for rodent activity, look for gnaw marks, droppings, urine, oil marks from fur, the sound of gnawing, and marks in dirt or flour. When looking for urine, you will need to use a black light.

To control mice and rats, you will need to remove clutter and block off places where they can nest. Protect or eliminate food sources. Set up and monitor traps. Traps are not just used to remove rodents, they can also give you important information about numbers and types of rodents trying to enter your facility. A professional pest control technician numbers and documents trap activity, which satisfies the requirements of auditors and inspection agencies.


Filth flies are known to carry and spread human pathogens like Salmonella and Listeria. This insect is drawn to decaying organic matter and can quickly spread bacteria through a facility. To monitor the activity of flying insects, you will need to set up electrocutors, baited fly traps and sticky traps. Keep track of numbers and types of flying insects, so you can track where they are coming in, or breeding from. It is important to clean all traps regularly. When government auditors find insect parts, they consider it a sign that insects are living in the facility. Professional pest control technicians have the knowledge base to find breeding sites, properly install traps and monitoring devices as well as perform insecticide fogging. They document all activity to meet the requirements of auditors.

Mice, rats, filth flies, stored product pests, fruit flies, pest birds, cockroaches, and other invasive pests can spread illness and disease in a warehouse. It takes careful inspections, good sanitation, properly installed deterrents, regular cleaning of all traps, rigorous documentation, and a knowledge of how these pests live, breed and nest.
