Thoroughly spray birds chest, behind the head, under the wings and around vent. For best results, invert birds during application or manually displace the feathers to ensure that spray thoroughly coats the birds skin. When applying product directly to birds, avoid spraying in eyes, nose and mouth. Product is not recommended for extremely old or debilitated birds or birds under 10 days of age. For an area spray, apply a coarse spray to floor area, especially to litter, around feed and water lines and to walls and support beams. Pay special attention to areas where pests have been seen or can find harborage such as cages, stalls, around the feeders and facility entry points. Treat at each grow-out or sanitation procedure, before reintroduction of poultry. Re-apply as often as necessary.
