Treat all plant surfaces including the undersides of leaves where most pests lay eggs. Repeat applications are usually required — follow the label's recommended interval between treatments to break the pest life cycle. Always apply during lights-off or in reduced light conditions to prevent leaf burn from foliar sprays.\u003c\/p\u003e\n\u003ch3\u003eIs Guardian Barrier Guard 250g safe to use on plants in late flowering?\u003c\/h3\u003e\n\u003cp\u003eCheck the pre-harvest interval listed in the product instructions before applying Guardian Barrier Guard 250g to plants in late flowering. Most pest control products specify a minimum number of days between last application and harvest. As a general rule, switch to the most plant-safe options available when within 2–3 weeks of harvest. Contact us at hello@apexgrow.com.au if you need guidance on safe late-flower pest management.\u003c\/p\u003e\n\u003ch3\u003eWill Guardian Barrier Guard 250g affect my beneficial insects?\u003c\/h3\u003e\n\u003cp\u003eBroad-spectrum pesticides can harm beneficial insects including predatory mites, lacewings, and ladybirds used in integrated pest management programs. If running beneficial insects, check whether Guardian Barrier Guard 250g is selective or broad-spectrum before applying. Biological control programs and chemical pesticides are generally not compatible without a washout period between them.\u003c\/p\u003e\n\u003ch3\u003eDoes Guardian Barrier Guard 250g ship fast within Australia?\u003c\/h3\u003e\n\u003cp\u003eYes — Guardian Barrier Guard 250g ships from our Australian warehouse with fast tracked delivery Australia-wide.
