Migrate is micro-encapsulated turf control for geese. It protects the turf 24 hours a day: no stains, no cross-species risks, no re-entry concerns. It can be tank mixed with other turf chemicals. A spray surfactant is recommended. It is a feeding aversion; when geese don't eat, they don't leave a mess. We suggest adding Invisi-Dye to this product, to make the grass taste AND look unattractive. 1 gallon treats 16,000 sq. ft! Mix 1 gl. concentrate with 3 gallons water. Water (rain) will NOT wash off product! Will not harm birds or people, and run-off will not contaminate nearby bodies of water!
