Fully HSE approved. Effective repellent combinations to be applied directly to birds and poultry as proactive ‘on bird’ deterrents to infestation or to rectify an existing problem. For knapsack application directly onto the birds: dilute contents of container in one go. For ongoing maintenance use 1:50 and where infestation exists use 1:20 parts water and repeat within seven days. Do not use in conjunction with chemical-based products, as this will render ours useless. HSE licence no: 8719.
