A thin placement is not a pile
Over-application can create avoidable airborne dust, visible mess and routes insects may avoid. Professional placement targets suitable cracks, voids or interception routes according to the label.
Keep products away from children, pets and food-contact surfaces as directed.
Dust is not instant confirmation
Desiccant action can take time and depends on contact. Monitoring and inspection are needed to judge whether activity is falling.
Do not combine it with incompatible cleaning or wet applications without professional advice.
