Smell deterrents are not effective during winter months because the cold temperatures suppress the smell. During the winter you need to use a strong taste deterrent. We use DeerPro Winter in the fall and DeerPro Spring/Summer during the growing season.

i know in vegtable gardens life boy soap keeps deer away. they dont like the smell. all you do is put a bar in an empty onions bag tie it to a post or stick with string. maybe that will help your problem too. worth a try right?

Protect holly from winter deer damage with DeerPro Winter Animal Repellent. One spray in the fall will protect woody ornamental evergreens all winter.
