The Grazers G3 Pest Deterrent Spray is an essential tool for gardeners, allotment holders, and hobbyist growers looking to protect their crops from common pests like caterpillars, cabbage white butterflies, and aphids. By utilizing a calcium-based formula with natural plant extracts, it offers a dual-action benefit of deterring pests while fortifying plant cell structure to stimulate healthy growth. While it is highly effective for vegetable and fruit gardens, users should note that the spray requires consistent reapplication every four weeks to maintain its protective barrier against hungry insects.

Yes, it is perfectly safe to use on vegetables and fruit plants, provided you wash your produce before eating as a standard practice.
No, the product is specifically formulated to deter pests while remaining completely safe for beneficial insects and pollinators.
We recommend reapplying the spray every four weeks to ensure the plant maintains a high enough concentration of calcium to deter pests.
While intended for outdoor garden and allotment use, it can be used on indoor plants, though it is specifically optimized for caterpillar and aphid protection in outdoor environments.
While the calcium is absorbed into the plant, heavy or persistent rainfall may reduce the effectiveness, necessitating an earlier reapplication.
Run the spray nozzle under warm water to dissolve any dried residue and ensure the trigger is fully depressed.
Ensure thorough coverage of both the top and underside of the leaves, as pests often congregate on the undersides.
This product comes in a 750ml ready-to-use spray bottle, meaning no dilution or specialized equipment is necessary. Simply shake the bottle well before each use to ensure the calcium solution is properly mixed. When applying, ensure an even mist covers all surfaces of the leaves and stems. Avoid spraying during the hottest part of the day to prevent leaf scorch and to allow the plant cells maximum time to absorb the calcium. Store the bottle in a cool, dry place out of direct sunlight to maintain the integrity of the formula between uses.
