Warehouses & Supermarkets
A warehouse is an important link in the retail chain leading from the processor to the consumer. Food warehouses vary in size, function, and physical condition, but they share one common feature- the need for a comprehensive sanitation program to protect stored food from attack by rodents, insects, birds, and other pests.
Type of Warehouse:
- Wholesale Grocers
- Supermarkets or stores
- Retail chains
- Public storage warehouse
- Manufacturer’s warehouse
- Cash & carry store
- Speciality warehouse
Food warehouses are regulated by the state and local regulatory authority. It is important to make thorough preparations before conducting an inspection. Gather as much background information as possible before you conduct the inspection. Advance information that will prove valuable might include:
- A current pest control program
- Current pesticides usages
- Current sanitation program
- A flow diagram or floor plan
- Type of products stored and packaging
- The average length of time a product remain in the store
- Information on any packaging, processing, or re-packaging
- Defective / rejected materials or breakage handling policy
- Shipping and receiving practices
- Procedure for bringing goods into the warehouse
- Information on general employee attitudes and co-operation between employees and management
- Stored grain pests
A.Pest Hot Spots
A certain section of the stores will be key areas for pest problems, requiring constant monitoring and more frequent treatment. These are delicatessen areas, bakery/confectionary area, restaurant/fast food area, storage area, pet food aisles, natural food bins, fruits and vegetable product section, employee break and locker rooms, meat department, indoor/outdoor trash refuse area, voids below and behind shelving and the corners where rows or banks of shelving meet.
B. Inspect“To be fully alert and conscious of your surroundings is the essence of inspection”.
Inspection is an information gathering an analysis technique that should at the minimum.
Answer the questions:
- Which pest(s) are present?
- Where are the pests located?
- How did they enter the structure?
- What conditions and practices conducive to infestation exist?
- Are there any conditions that may affect the type of pest management program being prescribed?
C. Prescribe :
Determine what needs to be done by analyzing the information gathered from your inspection and choose your strategies and options.
When formulating a prescription for a pest problem, you must ask yourself. What do you want to achieve?
- Get rid of the pest problem quickly (Flush out treatment – minimum a months time)
- Protect the area from re-infestation (Proofing measures within a month time)
- Identify adjacent areas/incoming materials/equipments/practices contributing re-infestation
- Monitoring and trapping
D. Treat :
Execute the treatment techniques properly. Treatment techniques are the actions taken to solve pest problems. They are options that focus on how the prescription will be implemented. Learning each technique will arm technicians with the important knowledge necessary to make informed decisions.
Crack & Crevice Treatment
The application of small amounts of insecticide into cracks and crevices in which insects hide or through which they may enter the building. Such openings commonly occur at expansion joints, between different elements of construction, and between equipment and floors. These openings may lead to voids such as hollow walls, equipment legs and bases, conduits, motor housing, junction, or switch boxes.
It is important to inject cracks in tile floors and walls adjacent to the dishwasher and floor drains, which are difficult harbourages to reach. In particular, large commercial dishwashers have pipes and support extending into the ceiling above the unit. German cockroaches can survive in harbourage area above suspended ceilings. Therefore any area adjacent to the dishwasher – such as cracks in walls or pipe collars around pipes penetrating walls should be treated.
Application to enclosed spaces where insects may live, hide or travel. Void treatments flush insects from their harborage, repel insects from the void or impassable (exclusion); or kill insects present within the void space. Examples of voids include hollow walls, hollow doors, spaces within equipment housings, false flooring and suspended ceilings. Some cracks and crevices lead to voids, while others have open access points.
Surface application to limited areas where insects are likely to be present, not exceeding two square feet in area. The goal is to control insects by exposing them to insecticide as they come in contact with treated surfaces. Applications are usually made along baseboards, foundations or on framing members where other application techniques are not practical.
The goal of ULV space treatment is to kill or control exposed stages of flying insects or crawling insects by exposing them to small droplets of insecticide delivered and dispersed into the air.
Direct Contact Treatment
Application of a wet spray to exposed insects for the immediate kill. Some situations require quick kill to prevent insects such as bees and wasps from stinging people. Other situations involve insects found in complex environments (eg. inside machinery or piles of debris) that limit the usefulness of other techniques.
General broadcast application to exterior areas of structures. Adequate pesticide coverage in targeted areas and proper penetration to the substrates where pests live, feed and travel, may be an important consideration for successful perimeter treatment.
Baits may be placed in cracks/crevices and harbourages for cockroaches, along with insect foraging trails for ants.
Exclusion involves altering the environment so pests cannot get through. Chemical exclusion repels pests from the area and reduces the likelihood that pests will enter or harbour. Usually accomplished by making crack and crevice or avoid injection treatments with silica aerogel or other material.
A technique of capturing pests as a means to identify, quantify or control adult stages of an infestation. The role of trapping can range widely from identifying insects present to measuring populations of insects or acting as a control mechanism.
Communication and education should be the verbal “transfer of value”. Since the customer’s perception of value is critical to customer retention, making sure that value is transferred to the customer during service is an important task for a successful pest management provider. The way we communicate and the messages being communicated are critical to success with every account.
“TERMITERA” of Pest management is a process that requires careful and on-going documentation of findings, recommendations, actions and communications. Proper documentation protects us from liability, provides internal communication, acts as a quality assurance mechanism for the technician and his supervisor, and can be used to express value to the customer.
Documentation also provides structure for delivering a customer’s special need or request. Follow-up can also be looked at as action taken to integrate past services with present or future actions. It shows customers that you care and you are aware of the pest management process in place which gives them a sense of value for continued pest management service.
