Trico Garden has been proven to give highly effective protection to trees, shrubs and garden plants against deer browsing. Trico Garden is a smell and taste deterrent based on emulsified sheep fat which deer will avoid as they find the smell and taste totally unappetising. It has the advantage over other repellents on the market in that it has good rainfastness, providing effective protection against deer damage during both the summer and winter. It is totally harmless to deer. Spray in autumn and spring to protect plants, trees and shrubs. Trico Garden is diluted with water and can be sprayed with hand or backpack sprayers.
