The storage of pesticides is a must to keep your pest control business running smoothly, however, proper storage can safeguard well water, surface water, human health, animal health and prolong the shelf-life of your pesticides. Therefore, taking the time to plan and implement a solid storage strategy can be vital to protecting your pesticides and the well-being of your surroundings.

Pesticide Storage

Below is a list of general guidance around pesticide storage:


    • Pesticide storage should be restricted to a first story room or area which as direct access to the outside. Do not store outdoors.
    • The pesticide storage area should be located away from direct sunlight, freezing temperatures and extreme heat.
      Where practical, the mixing area should be located close to the storage facility to minimize the distance that chemicals are carried.
    • Consideration should also be given to the additional area required by a mixing pad when selecting the site for storage.
    • Pesticides should be stored away from fertilizer, food, feed, potable water supplies, veterinary supplies, seeds and personal protective equipment to avoid contamination.
    • If possible, the area should be located at least four hundred feet (preferably down hill or down gradient) from any public or private drinking water supplies and two hundred feet (preferably down hill or down gradient) from surface water.
    • Avoid storing in areas that are prone to flooding


Equipment and Signage

    • Reduce the amount of pesticide stored the necessary amount to avoid chemical fires, explosions, and spills
    • Purchase pesticides in refillable containers that can be returned to your pesticide dealer
    • Post signs notating areas where pesticides are stored and keep storage areas locked when not in use
    • Post safety data sheets in a visible location so others can see how to property handle the chemicals



    • Make sure a back siphon prevention device is present when filling directly from any water source
    • Absorbent material such as re-usable gelling agents, vermiculite, clay, pet litter or activated charcoal should be on hand along with a garbage can and shovel to quickly contain and clean up any spills. The spilled pesticide should be contained – it should not be hosed down.
    • Install smoke and heat detection systems to aide in catching fires before they spread
    • Create an emergency response plan so all know what to do in case of a disaster
