i have heard many people talk about biologic and they did not have any luck. like they said deer just walk right past it. If i was you i would just pant somthin like a patch of corn or a patch of soy beans. i live on a farm so i dont worry about that stuff. we plant corn and sunflowers along with barley. we always find them in the sunflowers. well hope this helps. o by the way soy beans are high in protein so they are a good thing for a deers diet
