The Westland Bug Guard contains natural ingredients and will not harm beneficial insects such as bees and ladybirds. It works by promoting a plant reaction to defend itself against a wide range of pests, including aphids, whitefly, greenfly, mealybugs, and more. This helps to target and immobilize pests, preventing them from developing resistance. It also improves a plant's natural defenses, making it a suitable choice for organic gardening. The Bug Guard is pesticide-free and safe to use around bees and ladybirds. It is available in a size of 800ml.
